Energy Conservation Program: Test Procedure for Television Sets

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy.

ACTION: Notice of p roposed r ulemaking.

SUMMARY: The U.S. Department of Energy (DOE) proposes to establish a new test procedure for television sets (TVs) . DOE repealed the prior Federal test procedure for TVs on October 20, 2009, due to petitions from the California Energy Commission (CEC) and the Consumer Electronics Association (CEA) . CEC and CEA petitioned for the repeal in light of the June 13, 2009, Federal Communications Com mission ( FCC ) transition from analog to digital broadcast transmissions for TVs. In their petitions, t he CEC requested repeal of the regulatory provisions establishing the test procedure and defining “television set,” and the CEA petitioned for DOE’s adopt ion of the International Electrochemical Commission’s (IEC’s) test procedure IEC Standard 62087

- 2008 , “Methods of measurement for the power consumption of audio, video and related equipment.” DOE is proposing a new test procedure for TVs that was developed from existing industry test procedures including those by IEC, Environmental Protection Agency (EPA) , and CEA.

I. Authority and Background

A. General Title III of the Energy Policy and Conservation Act (42 U.S.C. 6291, et seq .; “EPCA” or, “the Act”) sets forth a variety of provisions designed to improve energy efficiency. (All references to EPCA refer to the statute as amended through the Energy Independence and Security Act of 2007 (EISA 2007), Pub. L. 110

- 140 (Dec. 19, 2007) ) . Part B of Title III (42 U.S.C. 6291

– 6309), which was subsequently redesignated as Part A for editorial reasons, establishes the “Energy Conservation Program for Consumer Products Other Than Automobiles.” This includes television sets (TVs), the subject of this notice . (42 U.S.C. 6292(a)( 12 ))

Under EPCA, this program consists essentially of three parts: (1) testing, (2) labeling, a nd (3) Federal energy conservation standards. The testing requirements consist of test procedures that m anufacturers of covered products must use (1) as the basis for certifying to DOE that their products comply with the applicable energy conservation stan dards adopted under EPCA, and (2) for making representations about the efficiency of those products. Similarly, DOE must use these test requirements to determine whether the products comply with any relevant standards promulgated under EPCA.7

B. Test Procedure Rulemaking Process

In 42 U.S.C. 6293, EPCA sets forth the criteria and procedures DOE must follow when prescribing or amending test procedures for covered products. Specifically, if DOE determines that a test procedure should be prescribed or ame nded, it must publish the proposed test procedure in the Federal Register and give interested parties an opportunity to provide public comment on the procedures. (42 U.S.C. 6293(b)(2 )) EPCA also provides that the test procedure shall be reasonably designed to produce test results which measure energy efficiency, energy

use , or estimated annual operating cost of a covered product during a representative average use cycle or period of use, and shall not be unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))

EISA 2007 amended EPCA to require DOE to implement a standby and off mode energy consumption measurement , if technically feasible, in test procedures where not previously present. Otherwise, DOE must prescribe a separate standby and off mode energy test p rocedure, if technically feasible. (42 U.S.C. 6295(gg)(2)(A)) EISA 2007 also requires any final rule to establish or revise a standard for a covered product, adopted after July 1, 2010, to incorporate standby mode and off mode energy use into a single amen ded or new standard, if feasible. (42 U.S.C. 6295(gg)(3)(A)) DOE recognizes that the standby and off mode conditions of operation apply to the product covered by this rulemaking. In response to this requirement, DOE proposes adopting provision s in the test procedures to address standby and off mode as discussed in section III.E.5 of this proposed rulemaking

.8

C. Rulemaking Background DOE adopted a test procedure for TVs on June 29, 1979 , codified at 10 CFR part 430, subpart B, appendix H . 44 FR 37938

. In May 2008 , DOE received petitions from both the California Energy Commission (CEC) and the Consumer Electronics Association (CEA) , which

were drafted in light of the June 13, 2009, Federal Communications Commission ( FCC ) transition from analog to digital broadcast transm issions for TVs 1

. As of June 12, 2009, the Digital Transition and Public Safety Act of 2005 required that all broadcasting stations transmit in digital to make analog frequencies available for public safety communications 4

. Both t he CEC and the CEA petitioned for repeal of the regulatory provisions establishing the test procedure

. CEC’s petition stated that the old test procedure was not capable of accurately measuring the energy consumption of modern TVs because TV broadcasting is no longer transmi tted via an analog signal 2

. In addition, the CEA petitioned for DOE’s adoption of the International Electrochemical Commission’s (IEC) test procedure IEC 62087

- 20 08 , “Methods of measurement for the power consumption of audio, video and related equipment.” 74 FR 53641. In light of these petitions , and the fact that the previous test procedure was largely obsolete for today’s products because of the mandated transition from analog to digital signal transmission, DOE repealed the test procedure on October 20, 2009 . The test procedure DOE is proposing today seeks to rectify the problem with the old test procedure by allowing for accurate measurement of the energy consumption of modern TVs.

DOE notes that the National Technology Transfer and Advancement Act of 19 95 (Pub. L. 104

– 113) directs Federal agencies to use voluntary consensus standards in lieu of Government standards whenever possible. Consequently, as described in today’s NOPR , DOE incorporate s by reference in its test procedures the generally accepted te st procedures or recognized industry standards , such as those issued by the IEC , the Environmental Protection Agency (EPA) , or the CEA , that provide either specific aspect(s) of the test procedure, or complete test procedure s , for the specified modes

.

As the first step in th is rulemaking to establish a new test procedure , DOE published a Request for Information on September 3, 2010 , 75 FR 54048, (the 2010 RFI ) requesting stakeholders to provide information and views on DOE utilizing both the IEC 62087

- 2008 and the ENERGY STAR ® Program Requirements for Televisions, Version 4.1 ( ENERGY STAR v. 4.1 ) as reference standards for the basis of a new DOE test procedure 3 . DOE also solicited comments on the key issues affecting the development of a new test procedure including the following:

1) A n appropriate method for ensuring screen brightness , 2) U tilizing the nine point video signal , 3) A n appropriate method for measuring screen luminance , 4) R equiring testing on all preset viewing modes ,

5 When the RFI was published, the most current version of EPA’s test procedure was ENERGY STAR v. 4. 1 and the most recent version of the IEC

- 62087 was 2008. Since then, EPA has published an updated version, “ENERGY STAR Program Requirem ents for Televisions, Version 5.3” and the IEC has published an updated version, “IEC 62087

- 2011”10

5) T esting multiple illuminance levels (specifically 10, 100, 150 and 200 lux) , 6) A n appropriate method for generating illuminance , 7) T he best possible signal source and connection to that signal source , 8) A n appropriate stabilization time for luminance and power measurements , 9) A n appropriate method of testing 3D energy consumption , 10) M easuring download acquisition mode (DAM) power,
11) Measuring internet connectivity power , 12) M easuring power saving technology energy (including presence sensors, display power management systems (DPMS), and high

- definition mu ltimedia interface consumer electronic controls (HDMI

- CEC)), and
13) T he scope of coverage for the rulemaking. 75 FR 54048

.
II. Summary of the Notice of Proposed Rulemaking In today’s NOPR , DOE is proposing a new test procedure for determining the energy use of TVs. The proposed test procedure includes measuring screen luminance and testing energy consumption for active (on mode), standby, and off modes

.

The luminance test is proposed to be performed by measuring the screen luminance while the TV is displaying t he IEC 62087

- 2011 three bar video signal in both the home and retail picture settings. The luminance test is being proposed to allow the ENERGY STAR program to utilize the measurement. The on mode test will measure on mode energy consumption when the TV is displaying the IEC 62087

- 2011 dynamic broadcast

- content video signal. I f the TV is11

shipped with an automatic brightness control (ABC) sensor enabled by default, on mode will be tested at various room illuminance levels. If the TV does not have an ABC sens or or the sensor is disabled by default , the test would be performed while the TV is in the home picture setting

.
DOE’s proposed standby test procedure incorporates both IEC 62087

- 2011 “Methods of measurement for the power consumption of audio, video and related equipment” and the CEA

“ Procedure for DAM Testing: For TVs ” ( CEA DAM test procedure ) . DOE’s proposed off mode test procedure incorporates IEC 62087

- 2011.

Although DOE is aware of TVs with additional modes , DOE is not proposing to require
test ing these , but rather is simply considering these modes and requesting comment on them. These modes include:

1) O n mode tests for TVs with internet connectivity ;

2) 3D mode , if capable ; and

3) S tandby

- active, low mode (when the internet is enabled but the TV is in st andby , and the TV is not sending or receiving external data , for those TVs with internet

access )

.12

To supports its efforts in developing a Federal test procedure, DOE conducted various
tests , the results of which can be found on the DOE website 4 . The information found on the DOE website helps support this NOPR by providing additional data and clarification. DOE conducted testing at two different testing facilities and therefore some of the data is organized according to where that data was collected. T he data from test facility one is denoted with numerical values , while the data from test facility two is denoted with alphabetical letters. The test facilities were determined to produce similar results as indicated in the Round Robin Test Program Final R eport for Televisions

. This information , found on the DOE website 5 , include s the following:

1) Television Test Procedure Comparison Chart which compares key aspects of various TV standards including IEC 62087

- 2011, CEA 2037

- 2010, ENERGY STAR version 5.1, CEC, BS EN 62087 “Methods of measurement for the power consumption of audio, video, and related equipment” , and EN 62087 “Methods of

meas urement for the power consumption of audio, video, and related equipment”

.
2) Video Signal of Test Patterns Comparison Table which compares the different advantages and disadvantages of particular video signals including the 3

- bar, 9

- point, DOE 5

- point, and dynamic video signals. DOE assessed these video signals based on their availability, impact on average picture level (APL) , affect on power limiting, and interested party input among other features.

3) Room Illuminance Measurements During TV Viewing: Pilot S tudy which summarizes a pilot study that DOE conducted to continuously measure room illuminance in nine homes over a period of a week or more as well as taking discrete

one - off measurements at different locations in the room. This document also sets out th e detailed methodology that DOE used for its pilot study.

4) Round Robin Test Program Final Report for Televisions that summarizes a round robin test study to assess the repeatability and reproducibility of TV energy test results . This round robin study uti lized the ENERGY STAR version 5.1 test procedure across three labs and compares their results.

5) Television Energy and Luminance Test Data Set which includes the energy and luminance data for all of the TVs on which DOE conducted testing.

a) Television Luminanc e Data which includes test results for luminance testing using the 9

- point (both perpendicular and off

- axis measurements), 5

- point Video Electronics Standards Association (VESA) , and DOE 5

- point video signals. DOE conducted luminance testing based on the E NERGY STAR version 5.1 test procedure but altered the video signal to determine which video signal was most appropriate. DOE used the 3

- bar static video signal specified in IEC 62087 Ed. 2.0 as well as the 9

- point, VESA 5

- point, and DOE 5

- point video signa ls as specified in this NOPR.14 b) Television Luminance Stabilization Period Data which includes graphs indicating how TV screen luminance changes over time and with respect to different stabilization periods. DOE took measurements of screen luminance after dif ferent stabilization periods to determine the most appropriate method for conducting luminance testing. DOE initially warmed

- up the TVs using the method from IEC 62087

- 2011 and then displayed the video signal for 15 minutes to conduct the luminance measure ment. The second luminance measurement was taken after a 10 minute warm

- up period followed by 2 minutes of a black screen. DOE tested this stabilization period for both the IEC 3

- bar and 9

- point video signals.

c) Television Power Data that includes test resul ts for power consumption testing while TVs are in various different modes. DOE conducted this testing according to the ENERGY STAR version 5.1 test method, but adjusted specific aspects on the TV to determine the energy consumption associated with that par ticular feature including volume, ABC, and internet connectivity.

d) Television Internet Standby Data which is comprised of data indicating the energy consumption when TVs are in standby mode and connected to various external sources including HDMI, cable, E thernet, and wireless internet. DOE conducted power consumption testing according to the ENERGY STAR v. 5.3 standby test procedure while alternating the specific internet connections present on the TV.15 e) Television 9 - point Video Signal Comparison Data that includes data depicting the difference between perpendicular and off

- axis measurements while the TV is displaying the 9

- point video signal. Luminance results were collected according to the ENERGY STAR version 5.1 test procedure, except that DOE altered th e video signal to the 9

- point video signal specified in this NOPR.

f) Television On Mode Automatic Brightness Control Data which includes the power and luminance data for TVs tested by DOE with ABC enabled by default across various room illuminance levels. A PowerPoint which charts some of this data is also included to demonstrate the range of implementation of ABC among TVs tested by DOE. DOE conducted power consumption testing according to the ENERGY STAR v. 5.3 (with additional room lighting levels) using the IEC dynamic test clip specified in IEC 62087 Ed. 2.0. Luminance results were collected according to the ENERGY STAR version 5.1 test procedure, using the 3

- bar static test pattern specified in IEC 62087 Ed. 2.0.

g) Television Download Acquisition Mode Data which includes data indicating the energy consumption associated with DAM mode. DOE conducted this testing on two TVs by configuring the internal electronic program guide (not enabled by default) and connecting to a subscription cable service by (1) coaxial cable only, (2) Ethernet only and (3) cable and Ethernet together. Results over a 24 hour period were recorded and c harted for each connection configuration.16 h) Television 3D Mode Data that contains data as to TV energy consumption while in various 3D modes. This testing was conducted on five TVs under the following modes : when the TV is displaying a 3D video signal, when the TV is up

converting a 2D video signal to 3D, and when the TV is receiving a video signal from a Blu

- ray player that has up

- converted a 2D video signal to 3D.

DOE believes that the proposed test procedure will accurately represent the energy consumption of TVs by capturing the annual energy consumption in on mode, standby mode, and off mode. However, DOE requests comments from interested parties on improvements or changes to the proposed test procedure. DOE will consider modifications that improve the

ac curacy, precision of language, or other elements of the procedure and/ or decrease the testing burden

. In submitting comments, interested parties should state the nature of the recommended modification and explain how it would improve upon the test procedu re proposed in this NOPR. Interested parties should also submit data, if any, to support their positions.

III. Discussion

A. Effective Date and Compliance Date of Test Procedure If adopted, the effective date for this test procedure would be 30 days after publication of the test procedure final rule in the Federal Register. At that time, the new metrics and any other measure of energy consumption which depends on these metrics may be represented pursuant to the final rule

. Compliance with the new test procedure for representation purposes would be required 180 days after the date of publication of the test procedure final rule. On or after that date, any such representations , including those made on marketing materials and product lab els,17

must be based upon results generated under the final test procedure proposed to be included in Appendix H to Subpart B of 10 CFR Part 430.

Furthermore, EPCA requires the Federal Trade Commission (FTC) to prescribe labeling rules for certain covered p roducts including TVs. (42 U.S.C. 6294 ( a ) (2) (I) ) Hence, the final DOE test procedure is required to be utilized by the FTC for labeling requirements and shall be

u tilized or referenced by other organizations, such as the EPA for its EN ERGY STAR specification for TVs . T his test procedure must also be referenced by the CEC in California and any other state regulation providing for the disclosure of information with respect to any measure of TV energy consumption once the test procedure becomes effe ctive 30 days after the test procedure final rule publication . The final rule would supersede any existing state test procedure for TVs to the extent the state regulation requires testing in a manner other than that required by the final DOE test procedure

. (42 U.S.C. 6297 ( a ) (1 ) )

B. Existing Industry Television Test Procedures While developing the proposed test procedure for TVs, DOE researched existing industry test procedures that measure TV energy consumption, as discussed in its 2010 RFI

. 75 FR 54048, 54 049. Among the most widely accepted are the IEC 62087

- 2011 and EPA’s “ENERGY STAR Program Requirements for Televisions, Version 5.3 ” (ENERGY STAR v. 5.3). 6 DOE also reviewed both the CEA

- 2037

- 2009 “Determination of Television Average Power Consumption”

6 ENERGY STAR v. 5.3 references ENERGY STAR v. 4.2; however, for the purposes of the NOPR, all references will be made in terms of ENERGY STAR 5.3 although testing was conducted using ENERGY STAR 5.1. < http://www.energystar.gov/ia/partners/prod_development/revisions/downloads/television/V5.3_Program_Require ments.pdf >18

and the CEC test procedures , and noted that th ese test procedures are largely based on both the EPA and IEC 62087 test procedures

. In response to the 2010 RFI, DOE received comments from interested parties on what they believed aspects of a robust test procedure should include, as well as on the validity of the existing test procedures that DOE reviewed and considered.

Several interested parties expressed general concerns and made suggestions pertaining to what should be considered when DOE developed its proposed test procedure. Consumer Electronics Retailers Coalition (CERC) expressed desire for a standardized test procedure and standard that are reflective of consumer use and that will not increase the cost of equipment. CERC further stated that a patch work of state regulations, mandating different test procedures for energy consumption, different standards, or different labels, will confuse consumers with conflicting or unclear information, and ultimately be counterproductive. (CERC, No. 10 at p. 1) CER C urged DOE to adopt a single federal test procedure for TV energy consumption, because it will better inform the public and better show energy savings . (CERC, No. 10 at p. 2) Natural Resources Defense Council (NRDC) asked that DOE develop a test procedure that allows flexibility for policy makers when setting standards such as allowing policy makers to require
test ing at different pre

- set picture settings and establish ing desired luminance ratios . ( NRDC, No. 5 at p. 1) Pacific Gas and Electric (PG&E) and a joint comment submitted by Southern California Gas Company, San Diego Gas and Electric Company, and Southern California Edison, henceforth referred to as “California Investor Owned Utilities (IOUs) ,” expressed desire for a test procedure that accounts for all current and future TV technologies. (PG&E, No. 12 at p. 1; California IOUs, No. 9 at p. 1) Finally, Sony asked that the test procedure provide adequate guidance and meaningful power consumption data without forcing manufacturers to perform
unnecessary , burdensome, and costly activities

. (Sony, No. 8 at p. 4)19

Environment Northeast (ENE) also had general recommendations for DOE’s proposed TV test procedure and suggested that the test procedure should be designed so that the test results reflect energy consumption in the field to the maximum extent possible. (ENE, No. 2 at p. 1) It urged DOE to develop a test procedure that only promote s energy management features that deliver significant savings in the field. (ENE, No. 2 at p. 1) ENE commented that ener gy consumption should be measured under a range of values (rather than using average values for ambient illumination, viewing distances and angles, and user adjustments to settings ) and that the average expected energy consumption of a model in the field b e calculated

. (ENE, No. 2 at p. 1) ENE believes that a test procedure that adheres to its direction will provide more accurate results and reduce the likelihood of manufacturers "designing to the test". (ENE, No. 2 at p. 1) Finally, ENE urged DOE to design a test procedure that does not discourage innovation. (ENE, No. 2 at p. 1)

Other interested parties commented that DOE should u s e existing test procedures when developing its test procedure. NRDC stated that DOE should review and adopt key portions of IE C 62087

- 2008 but noted that aside from the IEC 62087

- 2008 dynamic broadcast

- content video signal, the remaining sections of the IEC 62087

- 2008 test procedure are either incomplete or need revision. (NRDC, No. 5 at p. 2) CEA believes that future ENERGY STAR specifications should conform to the DOE test procedure, and that CEA

- 2037

- 2009 is suitable for adoption now with specified discrete change s , although the CEA did not specify these discrete changes

. (CEA, No. 13 at p. 2) CEA also urged DOE to adopt CEA

- 20 37

- 2009 to avoid the federal government using and promoting two different test procedures. (CEA, No. 13 at p. 3) CERC commented that the CEA

- 2037

- 2009 test procedure is the best test procedure because it is most familiar to manufacturers and retailers and added that it provides a reasonably accurate,20

practicable, and cost

- effective test procedure. (CERC, No. 10 at p. 2) SHARP urged the DOE to utilize IEC 62087

- 2008 and CEA

- 2037

- 2009 as a basis for its test procedure. ( SHARP , No. 14 at p. 1) Finally, Mitsubi shi requested that DOE adopt CEA

- 2037

- 2009 as its fundamental TV test procedure, and commented that if DOE finds that CEA

- 2037

- 2009 test procedure is inadequate, then it should base its test procedure on IEC 62087

- 2008. (Mitsubishi, No. 7 at p. 2)

Sony and CEC asked DOE to consider how its test procedure will affect state regulations and test procedures. Sony recommended that DOE create a test procedure that supersedes state regulations , while CEC believes that DOE should consider how its test proce dure will preempt CEC's test procedure. (Sony, No. 8 at p. 4) Specifically, CEC urged DOE to measure on mode
power, standby

- passive power, power factor , and luminance to ensure that the CEC can also require this testing . (CEC, No. 15 at p. 4)

In addition to considering stakeholder comments, DOE also conducted research and validation testing , which consisted of on, standby, and off mode energy consumption testing as well as luminance testing . The results of this research indicated that the IEC 62087

C. Scope

1. Products Covered by This Rulemaking In the 2010 RFI, DOE requested comments on the scope of the TV test procedure rulemaking. DOE received comments highlighting the similarities and differences between display s, TVs , and digital picture frames and the coverage of the test procedure. Unlike TVs, displays and digital picture frames do not have a TV tuner and therefore cannot receive digital broadcast content. While all of these technologies have the ability to display digital content they d o have some differences

. DOE notes that these differences are subtle , and therefore considered the possib ility of including all displays in this rulemaking

.
Display and TV technologies have started to converge and have become more similar in their capabilities. Given the convergence of display and TV technologies , PG&E , and the California IOUs advocated that the coverage of displays be explored i n this rulemak ing. They supported DOE's research into whether displays should be incorporated into the test procedure and specifically stat ed that DOE should study the category of displays less than 30 inches in greater detail as well as displays greater than 60 inches. (PG&E, No. 12 at p. 4; California IOUs, No. 9 at p. 4)

Other stakeholders opposed the inclusion of displays in the scope of the rulemaking. Sony asserted that TVs and displays are different in the following ways and therefore need to be tested differently

. TVs have different resolutions than displays because rate conversion circuits operate differently in the two product s ; resolution affects power consumption in displays but not22

in TVs ; and TVs with computer inputs do not fully comply with the VESA DPMS re quirements established for displays . (Sony, No. 8 at p. 4) Rather, Sony recommended that DOE use the same definition for TVs that is used in the ENERGY STAR v. 5.3 8

. (Sony, No. 8 at p. 4) Panasonic also does not recommend combining TVs and displays , as the y believe these are two distinct products. (Panasonic, No. 6 at p. 9) CERC commented that the scope of the test procedure should
not encompass all types of TVs because professional and retail displays require high luminance, sharpness, and performance. (CE RC, No. 10 at p. 3) CERC further commented that displays are designed differently than TVs due to their primary use ; namely, TVs are meant to be viewed from further distances than displays . (CERC, No. 10 at p. 3) Finally, CEA commented that DOE should not include displays in its rulemaking because the IEC 62087

- 20 11 dynamic broadcast

content video signal used for TV testing is not representative of typical content viewed on displays

. (CEA, No. 13 at p. 9) SHARP recommended that DOE remain focused on TVs that are used primarily by residential consumers and that commercial displays should not be included. (SHARP, No. 14 at p. 10)

DOE believes that some products can only be identified as TV s or displays on the basis of marketing. Some manufacturers ( e.g., Samsung and LG) make identical products that are market ed separately as a display and TV 9 . Moreover, there exist high

- definition displays sold with the option of purchasing an external t uner or speakers, which enable the customer to use the product as a TV

. Modern TV s can also typically be connected to computers and function as

8 ENERGY STAR v. 5.3 defines TV as: A commercially available electronic product designed primarily for the reception and display of audiovisual signals received from terrestrial, cable, satellite, Interne t Protocol TV (IPTV), or other digital or analog sources. A TV consists of a tuner/receiver and a display encased in a single enclosure. The product usually relies upon a cathode

- ray tube (CRT), liquid crystal display (LCD), plasma display panel (PDP) whic h are examples of the more common display technologies. 9 Personal Communication, DisplaySearch at SID Conference, May 22 2011.23

monitors

. Despite some overlap , DOE agrees with stakeholder s who suggested that TVs and displays are designed differently in most instances ( e.g. TVs are equipped with a tuner and displays are not )

. Although TVs and displays may be used interchangeably , the y are design ed to perform different task s . Displays have different screen resolutions that allow for clearer text reading and are typically set up in a 4:3 aspect ratio, as opposed to TVs which are primarily set
up in 16:9 aspect ratio which is optimal for displaying video

. DOE acknowledge s that despite the increasing overlap between these products, which may inc rease in the future, they currently have different usage patterns (e.g. they are used in different lighting conditions and locations as well as have different hours of operation)

.
The presence of a tuner is not an unequivocal distinguishing factor between TVs and other displays ; however, DOE still considers it a suitable way of broadly separating products which are generally intended to be used as displays or digital picture frames from those generally intended to be used as TVs (particularly in the smaller sizes)

. Accordingly, DOE proposes to define TV s with reference to displays but exclud ing displays if they are sold without tuners

. Further, DOE believes that this effectively excl udes from the proposed TV test procedure most displays and digital picture frames currently on the market.

TVs , unlike displays , often contain a tuner, which historically cost about $5.50 to the manufacturer and were projected to cost around $2. 7 0 by the end of 2010 10

. Modern TV s have similar inputs to displays , and their uses are increasingly similar, with the latest TV s having USB ports, PC inputs, video inputs, Ethernet cable inputs, and inputs enabling connection with

10 Quarterly LCD TV Cost & Price Forecast Model Report: Q1'11 History with Q2'11

- Q4'15 Forecast . Rep. DisplaySearch, 201024

cameras and MP3 players (e.g., Sams ung, Panasonic, Sony). Moreover, the latest display connection technology, High

- Definition Multimedia Interface (HDMI), is expressly designed to work with both TV s and displays and does not differentiate between the two. DOE is monitoring marketplace conve rgence and will consider updating the definitions and scope of the TV rulemaking in the future.

Consequently, DOE is proposing to include in the scope of th is rulemaking only displays of 15 inches and above which are sold with a tuner

. DOE acknowledges interested party comments stating that TVs and displays capable of show ing moving images are not similar in all ways. However, DOE believes that displays which are sold with a tuner are used in the same

manner as TVs , and is also taking into consideration that EPA requires displays to be tested with IEC 62087 Dynamic broadcast content

. DOE welcomes comment on the proposed scope of this rulemaking, particularly the inclusion of certain types of displays

. (See Issue 1 in section V. E ”Issues On Which DOE Seeks Comment”)

.

2. Definition of Television Sets TVs are a covered product under 42 U.S.C. 6292(a)(12) of EPCA

. DOE has the authority
to adopt test procedures for such covered products under 42 U.S.C. 6293(b)(2) of EPCA. Further, 42 U.S.C. 6295(l)(3) of EPCA specifically grants DOE the authority to promulgat e energy conservation standards for TV s . There are no statutory definitions for TV s under EPCA. In 1979 DOE adopted the following regulatory definitions for TVs (44 FR 39798 , June 29, 1979 ) , which are set forth in 10 CFR 430.2 :

Television set : means a color television set or a monochrome television set.25

Color television set means an ele ctrical device designed to convert incoming broadcast signals into color television pictures and associated sound.

Monochrome television set means an electrical device designed to convert incoming broadcast signals into monochrome television pictures and a ssociated sound.

Similar to DOE’s recently repealed test procedure (74 FR 53640, October 20, 2009), the current DOE definitions for TVs , developed in 1979 , are no longer appropriate and are proposed
to be updated as part of this rulemaking . The definition refer s to both color TVs and monochrome TVs ( also known as black

- and

- white TVs , which are rarely produced for the mass market today ) and w ith the evolution of technology, these definitions are too broad to adequately define the products covered by this ru lemaking. S ince the digit al switch

- over in 2009, analog TVs can no longer receive broadcast signals without an external digital tuner. Accordingly, the definitions require updating in order to reflect the realities of modern TV s and technological developme nts, including the convergence of display and TV technology , and to avoid the proposed rule being rendered ineffective.

DOE notes that at the time the Department repealed the test procedure for TV s (74 FR 53640, October 20, 2009), it also considered amending the definition of TV s on the basis of the transition to digital TV and found this factor in isolation to be an insufficient reason to amend the definition. At that time, the Department had not t aken into account other factors, including, rapid technology changes, the changing focus away from transmission towards display technology an d the phenomenon of TV and display technology convergence . The combination of these factors26

which are currently ev ident in this product market have led DOE to preliminarily determine that a revised definition of TVs is required.

CEA asked that DOE develop a definition of TVs that exclude s battery

- powered TVs because they inherently are designed for efficiency so as to improve battery life. CEA stated that battery

- powered TVs are different from typical TVs that require AC or main power supplies in their technology and usage patterns. (CEA, No. 13 at p. 9) Addit ionally, CEA commented that displays used for commercial applications and those that fully function on battery

- power should not be included in the scope of coverage. CEA further observed that portable and handheld displays are designed to be power efficien t and should therefore not be included in the scope of
coverage.
In today’s NOPR, after reviewing TV, display, digital picture frame market trends , and
accessory technolog ies , as well as other industry definitions from IEC, EPA, and CEA , DOE is proposing a n updated definition for TVs ; one that it believes will not become obsolete with rapid changes in technology. Accordingly, a broad technology

- neutral definition is proposed that includes all TVs and displays above 15 inches which are sold with a TV tuner. This definition also include s products that incorporate internal media readers (e.g. TV DVD combination units) while excluding laptop monitors, monitors having integrated computers (all

- in

- one integrated desktops), digital picture frames , and TVs operable by battery

- power . The exclusion of these products is based upon DOE’s belief that these products do not represent the typical TV usage and therefore should not be included in this definition

. DOE has determined the typical TV usage27

as a produc t that is commonly used seven hours a day 11 to watch dynamic visual information

. Consequently, DOE proposes the following definition to subpart A of 10 CFR 430.2 :
Television set (also referred to as “TV”) : A product designed to be powered primarily by mains power having a diagonal screen size of fifteen inches or larger that is manufactured with a TV tuner , and that is capable of displaying dynamic visual information from wired or wireless sources including but not limited to :

(1) B roadcast and similar services for terrestrial, cable, satellite, and/or broadband transmission of analog and/or digital signals; and/or

(2) D isplay

- specific data connections, such as Video Graphics Array ( VGA ) , Digital Visual Interface ( DVI ) , High

- Definit ion Multimedia Interface ( HDMI ) , DisplayPort, used typically for a computer or workstation that is not physically attached to the display; and/or

(3) Media storage devices such as a USB flash drive , a memory card , or a DVD ; and/or

(4) N etwork connections , usually using Internet Protocol, typically carried over Ethernet or WiFi

.

11 The Nielsen Company, LLC (2011).28

A TV may contain, but is not limited to, one of the following display technologies : liquid crystal display (LCD), light

- emitting diode (LED), cathode

- ray tube (CRT), and plasma di splay panel (PDP). TVs also include TV Combination Units that DOE has further defined in appendix H to subpart B of this part.

DOE notes that this proposed definition also include s TV combination units which are TVs that incorporate additional devices such as a digital video disc (DVD) player, Blu

- ray player, hard disk drive (HDD), or videocassette recorder (VCR ).These products maintain the general purpose of a TV but are combined with additional features

.

3. Other Definitions DOE’s proposed test procedure for TVs incorporate s definitions from IEC 62087

- 20 11 and ENERGY STAR v. 5

. 3. DOE is also proposing to add its own definition s , which were neither addressed by IEC 62087

- 20 11 nor ENERGY STAR v. 5.3 , and feels the proposed definitions are necessary

.
Specificall y , DOE proposes to include the following defined terms found in IEC 62087

- 20 11 : “additional functions , ” “off mode,” “standby

- active, high mode ,” “standby

- active, low mode ,” and “standby

- passive mode .” DOE is aware that section 42 USC 6295(gg)(1) of EPCA defines on, standby, and off modes, but believes that the proposed IEC 62087

- 2011 definitions provide added clarification to the test procedure. Second, DOE proposes to include the following defined term s found in ENERGY STAR v. 5

. 3 : “download acquisition mode, ” “luminance,” “on mode,” and “ TV combination unit

. ” For the reasons discussed below, DOE also proposes to develop new definition s for “home picture setting” a nd “retail picture setting.”29

a. Definition s Incorporated from IEC 62087

- 20 11 DOE is proposing to define “additional functions” using the definition found in IEC 62087

- 2011 . DOE is proposing to define “additional functions” because many TVs are now equipped with a wide variety of feature s , such as DVD players, memory card readers, music player inputs , that are not standard among different manufacturers and models

. Furthermore , DOE believes that th is definition from IEC 62087

- 20 11 is appropriate because it is clear , concise and widely accepted as an industry definition. The definition for additional functions found in IEC 62087

- 2011 also has not been redefined by any of the later published TV industry standards. Accordingly, DOE is proposing to define this term in section 2.1 (additional functions) of appendix H to subpart B of 10 CFR part 430 as follows:

Additional functions : Additional functions are functions that are not required for the basic operation of th e device. Additional functions include, but are not limited to a VCR unit, a DVD unit, a HDD unit, a FM

- radio unit, a memory card

- reader unit, or an ambient lighting unit

.
DOE is proposing to define “off mode” using the definition found in IEC 62087

- 20 11 , rather than the definition provided in ENERGY STAR v. 5.3. Although ENERGY STAR v. 5.3 also defines off mode, DOE believes the definition is too broad . Specifically, the ENERGY STAR v. 5.3 definition requires that an indicator be present that shows that th e product is in off mode , a clause that is not included in the IEC 62087

- 2011 definition. Accordingly, DOE is proposing to define this term in section 2.9 (off mode) of appendix H to subpart B of 10 CFR part 430 as follows:30

Off mode : Off mode is the mode w here the appliance is connected to a power source , produces neither sound nor picture and cannot be switched into any other mode with the
remote con trol unit, an external or internal signal

.
DOE is proposing a test for standby

- passive mode in this NOPR and thus provides a definition for the mode. DOE is proposing to define “s tandby

- passive mode” by using the IEC 62087

- 2011 definition for standby

- passive. This standby

- passive mode test is being proposed to capture the energy consumption associated with the TV when it produces neither sound nor picture. DOE believes that IEC has clearly and appropriately defined standby

- passive mode

. DOE is proposing to define this term in section 2.12 (standby

- passive mode) of appendix H to subpart B of 10 CFR part 430 as follows:

Standby

- passive mode : Standby

- passive mode is the mode in whic h t he appliance is connected to a power source, produces neither sound nor picture but can be switched into another mode with the remote control unit or an internal signal

.
DOE is proposing to define “standby

- active, high mode ” consistent with the IEC 62087

- 2011 definition for standby

- active, high

. IEC’s definition clearly and accurately captures the state of the TV while in standby

- active, high mode. DOE is proposing a definition for standby

active, high, sinc e DOE is also proposing a test in the standby

- active, high mode. Standby

- active, high mode would cover TVs when they are switched off with a remote, but remain active in

some manner. Th is include s TVs that are download ing information from the internet or c able while switched into standby mode

. Accordingly, DOE is proposing to define this term in31

section 2.13 (standby

- active, high mode) of appendix H to subpart B of 1 0 CFR part 430 as follows:

S tandby

- active, high mode : The appliance is connected to a power source, produces neither sound nor picture but can be switched into another mode with the remote control unit or an internal signal and can additionally be switched into another mode with an external signal and is exchanging/receiving data with/from an external source .
DOE is proposing to define “standby

- active, low mode ” consistent with the IEC 62087

- 2011 definition for standby

- active, low

. Although DOE is not propo sing a test in the standby

active, low mode, DOE is still proposing a definition for standby

- active, low to remain consistent with IEC 62087

- 2011 and to ensure that this particular mode is not tested. DOE has reviewed existing industry definitions, TV technology, and TV operating modes and believes that IEC 62087

- 2011 clearly separates distinct TV operating modes and defines each of these modes appropriately. Standby

- active low mode would cover TVs when they are switched off with a

remo te and can be switched into other modes via an external signal

. Accordingly, DOE is proposing to define this term in section 2.14 (standby

- active, low mode) of appendix H to subpart B of 10 CFR part 430 as follows:

S tandby

- active, low mode : The appliance is connected to a power source, produces neither sound nor picture but can be switched into another mode with the remote control

u nit or an internal signal and can additionally be switched into another mode with an external signal

.32

b. Definitions Incorporated from ENERGY STAR v. 5.3 DOE proposes to include a definition for “d ownload acquisition mode ” (otherwise known as DAM) in its test procedure that is identical to the definition found in ENERGY STAR v. 5.3

. The DAM involves a TV’s download of data while it produc e s neither sound nor picture. Th e definition allows readers to more clearly under stand the DAM energy consumption test procedure. The energy consumption associated with DAM is measured when the TV is downloading information from an electronic program guide (EPG)

. DOE also believes that the ENERGY STAR v. 5.3 definition is appropriate because it is a wide ly accepted i ndustry definition and the term is not defined in IEC 62087

- 2011

. Accordingly, DOE is proposing to define this term in section 2.3 (download acquisition mode) of ap pendix H to subpart B of 10 CFR part 430 as follows:

Download acquisition mode : Download acquisition mode is the power mode in which the product is connected to a mains power source, produces neither sound nor picture, and is actively downloading data. Data downloads may include channel listing information for use by an electronic programming guide, TV setup data, channel map updates, firmware updates, monitoring for emergency messaging/communications or other network communications.

DOE is proposing to define “luminance” by incorporating the definition found in ENERGY STAR v. 5.3. DOE believes that the ENERGY STAR v. 5.3 definition is appropriate because it is widely accepted within the industry and t he term is not defined in IEC 62087

- 20 11

. Further, th e ENERGY STAR v. 5.3 definition is appropriate because DOE is proposing the luminance ratio so that it may be used in the ENERGY STAR test procedure. The ENERGY33

STAR v. 5.3 definition is clear and concise and provides the manufacturer with a thorough under standing of what is meant by luminance to allow for luminance testing. Accordingly, DOE is proposing to define this term in section 2.8 (luminance) of appendix H t o subpart B of 10 CFR part 430 as follows:

Luminance: Luminance is the photometric measure of the luminous intensity per unit area of light traveling in a given direction, expressed in units of candelas per square meter (cd/m2).

DOE is proposing to define “on mode” using the definition found in ENERGY STAR v. 5.3 , rather than the definition provided in IEC 62087

- 2011

. ENERGY STAR v. 5.3 defines “ on mode ” more broadly, stating that the TV can be providing “one or more of its primary functions.” On the other hand , the IEC 62087

- 2011 definition specifies that the TV must be producing both sound and picture

. Although many TVs will produce sound and picture, DOE’s proposed scope may include units that are not able to produce sound (e.g. computer monitor that does not include speakers) . Because DOE does not want to prevent those products from being
test ed in the “ on mode ” , DOE is proposing to exclude any references to sound consistent with the definition from ENERGY STAR v. 5.3 in section 2.10 (on mode) of appendix H to subpart B of 10 CFR part 430 as follows:

On mode : On mode is the power mode in which the product is connected to a mains power source, has been activated, and is providing one or more of its principal functions.34

DOE is proposing to define “ TV combination unit ” using the definition found in ENERGY STAR v. 5.3

. IEC 62087

- 20 11 defines multi

- function equipment, which may be considered similar to TV combination unit, but this term is not specific to TVs. Defining the term TV combination unit provides clarity to the test procedure since these particular TVs may require special consideration when being test ed

. Acco rdingly, DOE is proposing to define this term in section 2.16 (TV combination unit) of appendix H to subpart B of 10 CFR part 430 as follows:

TV combination unit: TV combination unit is a television in which the TV and one or more additional devices (e.g., DVD player, Blu

- ray Disc player, Hard Disk Drive) are combined into a single enclosure, and which meets the following criteria: a) it is not possible to measure t he power of the individual components without removing the product housing; and b) the product connects to a wall outlet via a single power cord.

c. New Definitions for Incorporation DOE is proposing to define “home picture setting” in its test procedure. DOE developed this definition because neither IEC 62087

- 2011 nor ENERGY STAR v. 5.3 provide s a definition for this particular setting. ENERGY STAR v. 5.3 does reference a home mode (or default mode), as the mode in which the TV is shipped. In order t o elimina te confus ion between picture settings and testing modes (such as on mode, standby mode, and off mode), defining home picture setting helps clarif

y how to conduct both the luminance and on mode tests since home picture setting is utilized for conducting par t of the luminance test as well as the on mode test. DOE believes that defining home picture setting will improve the consistency in which products are tested across labs. DOE is proposing to define this term in section 2.4 (home picture setting) of appendix H to subpart B of 10 CFR part 430 as follows:35

Home picture setting: (or default picture setting) is the picture setting which is recommended by the manufacturer from the initial set up menu or the mode that the television comes shipped in if no setting is recommended.

Finally, DOE is proposing to define “retail picture se tting” in its proposed test procedure

. Retail picture setting is a picture setting present on most TVs and corresponds to the brightest preset selectable picture setting. Although ENERGY STAR v. 5.3 uses the term retail mode in its specification , it does n ot provide a definition of this mode

. So as not to confuse picture settings with testing modes (such as on mode, standby mode, and off mode) , DOE is proposing to utilize the term “ retail picture setting ” instead of the term “ retail mode ”

. In the proposed DOE test procedure, retail picture setting is one of the two picture settings that the TV is set to for luminance testing. Therefore, DOE believes that defining retail picture setting clarifies the requirements of the test procedure

. DOE i s proposing to define this term in section 2.11 (retail picture setting) of appendix H to subpart B of 10 CFR part 430 as follows:

Retail picture setting : is the preset picture setting in which the TV produces the highest luminance during the on mode conditions.

D. Testing Conditions and Instrumentation

1. Accuracy and Precision of Measurement Equipment

a. Power Supply In this NOPR, DOE is proposing a slightly mod ified version of the power supply specifications from IEC 62087

- 2011 . DOE proposes to limit the input voltage and frequency used in its test procedure to 115 V at 60 Hz, rather than including a general requirement that the36

TV be tested at “the nominal volt age of the region,” as in IEC 62087

- 20 11

. DOE is also proposing to add a power factor measurement requirement

. The power factor measurements are based on those found in IEC 62087

- 2011 as well as ENERGY STAR v. 5.3

.
DOE is also proposing certain specifications for test tolerances. First, DOE is proposing to incorporate tolerances for voltage and frequency identical to those in ENERGY STAR v. 5.3 , which specifies that the voltage and frequency be maintained at ± 1 perc ent rather than ± 2 percent , as required by IEC 62087

- 2011

. DOE believes that this will not impose undue burden because many interested parties are already accustomed to these more stringent specifications required to meet ENERGY STAR s pecification s. Secon d, DOE is proposing to add a tolerance of power measurements consistent with that in ENERGY STAR v. 5.3. As mentioned above, ENERGY STAR v. 5.3 refers the reader to ENERGY STAR v. 4.2 where these specifications can be found. Third , DOE is proposing to add the requirements for total harmonic distortion (THD) consistent with that in IEC 62087

- 2011 , which requires that the harmonic components not vary by more than 5 percent . While ENERGY STAR v. 5.3 has requirements for THD that are

more stringent ( 2 percent) , DOE believes that these requirements may impose undue burden on manufacturers by requiring the purchase of more expensive equipment. DOE believes that the cost of more expensive equipment ( e.g., a power supply unit as found by market research) outweighs the benefits of stricter THD requirements , therefore less stringent requirements are being proposed

. DOE believes that the requirements that it is proposing to incorporate are accepted within industry and are sufficient to ensure a repeatable and reproduci ble test procedure. THD impacts the quality and stability of the electricity being received by the TV which can impact energy consumption. High levels of THD can increase current draw on TVs resulting in high circuitry temperatures and inefficiencies. The language proposed to ensure that37

the correct power is being supplied to the TV is being incorporat ed in section 3.1.1 ( p ower

s upply) of appendix H to subpart B of 10 CFR part 430 is as follows :

Carry out m easurements using a power supply providing voltage of 115 V at 60 H z. .
The fluctuation of the voltage supplied during the tests shall not exceed ± 1 percent . The frequency fluctuation and the harmonic components of the supplied power shall not exceed ± 1 percent and 5 percent respectively.

b. Power Meter DOE is proposing to incorporate specifications for the power meter used to collect the power data for the TV test. DOE plans to slightly modify the specification found in IEC 62087

- 2011 to include more guided instructions on the sampling rate. Rather than setting the sampling rate “high enough to achieve an accurate measurement” as required in IEC 62087

- 2011, DOE is proposing that samples be taken once per second or more frequently. This sampling rate is generally accepted by the industry and found in IEC 6 2301

- 2011. This sampling rate should not be difficult to accomplish and produces a more repeatable power measurement than the measurement specified in IEC 62087

- 2011. Specifying the proposed sampling rate decreases the chances of missing trends and power s pikes. The duration of testing remains the same and typically only a few changes to the data acquisition program are required to modify the sample rate. The language proposed to ensure that the correct power measurements are taken is being incorporat ed in section 3.1.2 ( power m eter) of appendix H to subpart B of 10 CFR part 430 is as follows :38

The measurement shall be carried out directly by means of a wattmeter, a wattmeter with averaging function , or a watt

- hour meter , by dividing the reading by the measu ring time. For TV s for which the input video signal varies over time, use a wattmeter with an averaging function to carry out the measurement.

The language proposed to ensure that the correct sampling rate for which the power
measurements shall be taken is being incorporat ed in section 3.1.2.1 of appendix H to subpart B of 10 CFR part 430 is as follows :

The sampling rate of the watt

- hour meter or wattmeter with averaging function shall be one measurement per second or more frequent.

The language p roposed describing the power measurement uncertainty is being incorporat ed in section 3.1.2. 3 of appendix H to subpart B of 10 CFR part 430 is as follows :

P ower m easurements of 0

. 5 W or greater shall be made with an uncertainty of less than or equal to 2 percent ( at the 95 percent confidence level )

. Measurements of power of less than 0

. 5 W shall be made with an uncertainty of less than or equal to 0

. 01 W ( at the 95 percent confidence level ) . The power measurement instrument shall have a resolution of:

• 0.01 W or better for power measurements of 10 W or less;

• 0.1 W or better for power measurements of greater than 10 W up to 100 W;39 • 1 W or better for power measurements of greater than 100 W.

DOE is also proposing to require that, as part of the test procedure , the power factor of the TV be recorded while in “ on mode ” consistent with that in ENERGY STAR v. 5.3. DOE believes that requiring a power factor measurement will not impose undue burden on manufacturers because the ability to measure power factor is widely available on power meters. The power factor measurement only requires that the power factor be recorded while the on, standby, and off modes are measured. DOE is proposing to require this measurement because power quality can impact energy consumption and measuring the power factor will allow other regulating bodies the flexibility to consider requirements for power quality. The language proposed to ensure that the power factor and real power consumed are taken is being incorporat ed in section 3.1.2.2 of a ppendix H to subpart B of 10 CFR part 430 is as follows :

The power measurement instrument used shall measure the power factor and the real
power consumed regardless of the power factor of the device under test.

c. Light Measurement Devices i. Luminance Contact a nd Distance Meters Light measurement devices (LMDs) are used to measure the luminance of the TV screen

. DOE is aware of two primary categories of LMDs that are used to make luminance measurements: contact meters and distance meters. In response to the 2010 RFI, DOE received
comments advocating that the DOE test procedure for TVs allow the use of the contact meter to measure luminance . Panasonic stated that although there are many valid methods of measurement, a contact measurement is easier to compl y with since it prevents ambient light40

from interfering with the measurement and eliminates the need for a dark room. (Panasonic, No. 6 at p. 4) NRDC also supports the contact method of measuring luminance as it simplifies the performance of the test due t o it being unnecessary to adjust the room lighting levels. (NRDC, No. 5 at pp. 4

-- 5)

In this NOPR, DOE is proposing to allow the use of either a distance meter or a contact
meter to measure luminance for purposes of the DOE test procedure , so long as t he meter meets the specifications detailed in section III.D.1.c.ii of the NOPR. DOE is aware that each type of meter has specific advantages. While distance LMD meter s are typically less accurate and require the use of a dark room for luminance measurements, they are less expensive th a n contact LMD meters. DOE is also aware that t he use of a dark room adds burden to the procedure by increasing both cost and set

- up time

. Alternatively, the use of a contact LMD meter would reduce set up time (with regard to both aligning the meter as well as removing the need for a dark room) and will have a more accurate measurement since these meters typically have a higher accuracy ; ho wever, contact meters themselves are more expensive

. T hrough testing, DOE has learned that the two types of meters yield similar results when used to test TVs 12

. Therefore, in section 3.1.3 (light measurement device) of appendix H to subpart B of 10 CFR part 430 , the test procedure a llow s the use of either meter as long as it meets the specifications outlined below. By allowing the use of different meters it provides more flexibility, while ensuring the accuracy of the measurement and providing comparabl e results

.

U.S. Department of Energy. August 2, 2011. < http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html >41 ii. L ight Measurement D evice Specifications
In this NOPR, DOE is proposing to incorporate specifications for the LMD s used in performing the test procedure

. Neither IEC 62087

- 2011 nor ENERGY STAR v. 5.3 provide s specific requirements with respect to LMDs. Consequently , DOE has developed proposed specifications for today’s NOPR. To develop these, DOE researched existing test procedures and standards that provide LMD specifications. DOE has found that the VESA Flat Panel Display Measurements Standar d v. 2 provides tolerances for LMDs. VESA specifies that the luminance must be within ± 5 percent and repeatability must be less than ± 0.5 percent of the luminance or the uncertainty introduced by any digitalization over a five minute period. DOE also res earched available LMDs for testing to develop the following proposed requirements.

DOE is proposing , in section 3.1.3 ( l ight m easurement d evice) of appendix H to subpart B of 10 CFR part 430 , that all LMDs have an accuracy of ± 2 percent ( ± 2 digits ) of the digitally displayed value and repeatability within 0. 4 percent ( ± 2 digits ) value . DOE is also proposing that the LMD should have an acceptance angle of 3 degree s or less

. To determine the precision of a measured number, the displayed value on the meas uring device needs to be taken into consideration. The increment of the last significant digit is said to be the accuracy of the display and 2 digits is twice the interval. The overall tolerance of LMDs is found by taking (+/

- ) the absolute sum of 2 percen t and 2 significant digits of the measured value

.

DOE believes that these criteria are sufficiently stringent to ensure that measurements will be repeatable and accurate , without imposing burden on manufacturers by requiring overly42

precise measurement devi ces . However, DOE welcomes comments on the proposed LMD specifications

. (See Issue 2 in section V.E ”Issues On Which DOE Seeks Comment”).

2. Test Room and Set

- Up Criteria DOE received comment s from interested parties requesting that it clarify how to set up the TV for testing. Specifically, N RDC requested that DOE review the requirements in IEC 62087

- 2008 and urged DOE to provide sufficient clarity on preparing the TV before testing. (NRDC, No. 5 at p. 2) DOE has analyzed IEC 62087

- 2008 as NRDC requested and found that the requirements in IEC 62087

- 2008 are similar to those found in IEC 62087

- 20 1 1. PG&E and California IOUs also requested that DOE require a standard test set

- up that ensures the most robust results possible. (PG&E, No. 12 at p. 3; California IOUs, No. 9 at p. 3) DOE has analyzed both IEC 62087

- 2011and IEC 62087

- 20 08 , and has evaluated other existing TV test procedures to develop proposals for creating dark room conditions, ambient temperature and humidity, THD , and signal source generation , with the goal of ensuring repeatable res ults. The proposals are discussed in detail in the following sections.

a. Dark Room Conditions DOE is proposing that , i f the lab technician elects to use a distance meter for luminance testing, it must make the measurements in dark room conditions , similar t o the requirement in ENERGY STAR v. 5.3. DOE is proposing , in section 4.2 ( d ark r oom c onditions) of appendix H to subpart B of 10 CFR part 430 , language from t he requirement in ENERGY STAR v. 5.3 , which (with minor modification) , states: “ A ll luminance testing shall be performed in dark room conditions . Display screen illuminance... as measured with the UUT in [o] ff [m] ode shall be less than or equal to 1.0 lux

. ”43

b. Ambient Temperature and Humidity DOE is proposing ambient conditions consistent with IEC 62087

- 20 11 and ENERGY STAR v. 5.3 , which both require that ambient temperature be 23°C ± 5° C

. ENERGY STAR v. 5.3 further specifies that relative humidity must be between 10 and 80 percent , which DOE is also proposing to require in its test procedure

. Because these are both widely accepted test methods, and each of the temperate and humidity ranges is quite large, these requirements should be reproducible across a wide range of test laboratories

. These ambient condition requirements are being proposed in sectio ns 4.3 (a mbient t emperature c onditions) and 4.4 ( a mbient r elative h umidity c onditions) of appendix H to subpart B of 10 CFR part 430

.

c. Signal Source and Generation In the 2010 RFI, DOE requested feedback from interested parties regarding the signal

source a s well as the input cable to be used when testing. 75 FR 54048, 54050. As discussed below, i nterested parties were generally in agreement that the input cable should be HDMI, if the TV has an HDMI input

. If the TV does not have an HDMI input , DOE has propo sed a list of alternative connections in the order in which they should be used to conduct testing , which can be found below. Interested parties were also in support of using a Blu

- ray player as the signal source for testing.

Mitsubishi, Sony, LG, NRDC, Panasonic, CEA, CEC, PG&E , and California IOU s were all in support of DOE using HDMI as its preferred input cable. Mitsubishi recommended that DOE require an HDMI cable be used if the input exists and component cables be used if HDMI inputs do not exist. ( Mitsubishi, No. 7 at p. 5) Sony similarly commented that a HDMI input cable should be the preferred input cable, and if it not available, the next highest resolution input44

should be used. (Sony, No. 8 at p. 3) LG supported using an HDMI input cable because it has a digital signal and other sources have calibration issues. (LG, No. 3 at p. 1) NRDC recommended that DOE use a HDMI input cable if the input is available. If not available, then a component input cable should be used

. NRDC also stated that VGA con nectors should not be allowed to serve as the means to input the content. (NRDC, No. 5 at p. 6) Panasonic agree d that a HDMI input cable should be used if available. (Panasonic, No. 6 at p. 6) CEA agreed that a HDMI input cable should be used if it is avai lable, but stated that variation between different inputs is minor. (CEA, No. 13 at p. 7) CEA further commented that it is vital to allow various different input cables to be used because some TVs are produced with neither a HDMI input nor a component inpu t. (CEA, No. 13 at p. 7) Ecos C onsulting found in its previously cited report the effect of different input cables on the test results. Their report recommended that an HDMI input cable be

use d for testing because it produced similar results to a standardi zed signal generator unlike component and VGA inputs 13

.

As outlined above, c omments from all interested parties agreed that an HDMI input should be the preferred input

. Some interested parties also advocated that alternative inputs should be allowed if an HDMI input is not available. DOE acknowledges that all TVs may not be shipped with an HDMI input available, and therefore is proposing the f oll owing order for inputs: HD MI/DVI, VGA, component, S

- Video , and finally composite. If none of these inputs are available, the highest resolution input must be used

. DOE believes that by proposing a n input format hierarchy , it will ensure consistency and repeatability between tests w ithout i m posing

undue burden upon manufacturers . However, DOE welcomes comments on the purposed input formats hierarchy

. (See issue 14 in section V.E “Issues on Wh ich DOE Seeks Comments”)

DOE also received comments on the signal source to be used for testing

. NRDC commented that a signal should not be generated by a personal computer ( PC ) . NRDC preferred that a standard method of generating signal be used, but did n ot specify what the preferred method should be. (NRDC, No. 5 at p. 6) Panasonic believe s that the Blu

- ray player is the most appropriate device to supply the IEC 62087

- 2008 dynamic broadcast

- content video signal , which is the same as the IEC 62087

- 2011 dynamic broadcast

- content video signal. (Panasonic, No. 6 at p. 6) CEC concurs with the recommendations made in the report done by Ecos Consulting regarding signal sources, which recommends a signal generator with an HDMI input connection

. (CEC, No. 15 at p. 3) PG&E and California IOUs also cited the report done by Ecos Consulting, but commented that DOE should conduct additional testing on various size TVs with different display technologies to confirm the proper s ignal source. (PG&E, No. 12 at p. 3; California IOUs, No. 9 at p. 3) SHARP recommend ed that DOE not require a specific signal source like CEA

- 2037

- 2009

. (SHARP, No. 14 at p. 7) SHARP commented that there should be no dependency on the nature of the source (Blu

- ray player, computer, etc), as long as the decoder and signal are properly implemented according to existing and well

- known standards. (SHARP, No. 14 at p. 7)

The IEC 62087

- 20 11 dynamic broadcast

- content video signal, which is discussed further in section III.E.3.a of this NOPR, is supplied in two formats for testing, DVD a nd Blu

- ray. DOE acknowledges interested party comments recommending that a particular signal source should not be used but believes that establishing a specific signal source will increase repeatability and46

reproducibility

. As some commenters requested, DO E is proposing to require testing using a Blu

- ray player. The TV market is moving towards watching TV in high

- definition, as evidenced by increased production of high definition TVs and broadcasting of high definition channels. Blu

- ray players produce a 10 80p image that yields far more detail than the 480p image provided by DVD ; therefore, DOE is proposing that it be used for testing. DOE welcomes comments on the signal source and generation specifications proposed in this NOPR

. (See Issue 3 in section V.E ”Issues On Which DOE Seeks Comment”)

.
E. Test Measurement s As previously mentioned, DOE is proposing a test procedure largely based on IEC 62087

- 20 11 , with some modifications to improve the repeatability as well as tailor the procedure to the U

. S

. market

. DOE is proposing that the following test measurements be taken as described in the following sections

.

1. Picture Settings to Test In the 2010 RFI, DOE request ed comment on testing the TV in multiple power consuming modes. For luminance testing, ENERGY STAR v. 5.3 requires that the TV be tested in two picture settings : home mode and retail mode

. As stated earlier , DOE is proposing to replac e the terms home mode and retail mode (as used in ENERGY STAR v. 5.3) with home picture setting and retail picture setting. This is to distinguish the lumi na nce picture setting from the testing modes for energy consumption

. IEC 62087

- 20 11 does not reference luminance testi ng . Alternatively, for power testing, both IEC 62087

- 20 11 and ENERGY STAR v. 5.3 require that TVs be tested only in the home picture setting . DOE received comments and is considering testing energy consumption in picture settings other than the home pictur e setting

.47

Numerous commenters informed DOE that only a limited number of consumers switch their TVs out of the home picture setting , and therefore DOE should only require testing in the home picture setting. O ther interested parties suggested that DOE analyze all preset picture settings to determine the energy consumption of all possible picture settings

. Mitsubishi commented that manufacturer statistics show that less than 5 percent of TV viewers ever utilize

non - default display settings. (Mitsubishi, No. 7 at p. 2) PG&E and California IOUs stated that DOE should collect and analyze available technologies ( e.g . , LCD, plasma ) in several selectable preset picture settings : the dimmest setting , home setting , and retail setting . (PG&E, No. 12 at p. 1; Calif ornia IOUs, No. 9 at pp. 1

- 2) PG&E and California IOUs also urged DOE to develop the test procedure such that any preset picture setting may be measured using the procedure. (PG&E, No. 12 at p. 2; California IOUs, No. 9 at p. 2) Finally, they suggested tha t the DOE should obtain and analyze data on consumer home viewing habits

. (PG&E, No. 12 at p. 2; California IOUs, No. 9 at p. 2) SHARP commented that because consumers do not adjust their TV settings and it is not possible to predict the popularity of each picture setting , multiple picture settings should not be tested. (SHARP, No. 14 at p. 4)

DOE also received comments desiring that only the home picture setting should be used for testing

. SHARP stated that there are no reliable data on the popularity of modes that can be applied across the industry, and, therefore, the out

- of

- the

- box setting remains the best predictor of actual power use. (SHARP, No. 14 at p. 3) Sony commented that there is little information regarding consumer preferences for preset pict ure settings . Sony’s call center data indicates that more than 95 percent of returned sets remain in the home picture setting when received , while i nformation obtained during CEC's rulemaking process suggests that consumers tend to use the home picture set ting . (CEC, No. 15 at pp. 2

-- 3 and Sony, No. 8 at p. 2) NRDC commented that48

to the extent a TV has a “forced” set up menu; the test should be performed on the TV as shipped after selecting the home picture setting in the menu . (NRDC, No. 5 at p. 3) CERC believes that the test procedure should focus on the energy consumption of TVs in the home picture setting due to the difference in room lighting and energy consumption of TVs in retail and home settings. (CERC, No. 10 at p. 3) CEA commented that DOE should not require testing of other preset viewing settings because it is time consuming and will not yield useful information because consumer viewing habits are unknown and preset viewing settings are not standard across manufactu rers. (CEA, No. 13 at p. 5)

In this NOPR, DOE is proposing that luminance measurements be taken in both the home and retail picture settings , and that power measurements (for TVs without ABC enabled) only be taken in the home picture setting

. As many int erested parties commented, most consumers d o not switch their TVs out of the picture setting in which they are shipped. Therefore, requiring power measurements in the retail picture setting or any other alternative picture settings may cause unnecessary bu rden on manufacturers by increasing testing time. A luminance measurement in both the home and retail picture setting must still be taken in order to generate a luminance ratio , which is utilized by other regulatory programs such as ENERGY STAR

. However, D OE is also considering testing on mode energy consumption in picture settings other than the home picture setting. DOE is aware of some TVs that a re eq uipped with remotes that have easy

- to

- access shortcuts that enable the user to switch from the home pictu re setting to other preset picture settings (sport, vivid, movie, etc.), without requiring that the user enter the main menu

. Although interested parties commented that consumers do not switch between picture settings, DOE believes that if TV remotes are designed with shortcuts to switch between preset picture settings, more consumers may do so, either accidently or intentionally

. For this reason, DOE is49

considering whether this should be taken into account in the test procedure. In particular, DOE is

cons idering testing on mode energy consumption in some of these additional preset picture settings

. Possible approaches could include testing in the highest and lowest energy consuming preset picture settings, while displaying the IEC 62087

- 200 11 dynamic broad cast

- content video signal , or the brightest and dimmest preset picture settings

. An additional approach could include testing in all preset picture settings. DOE invites comments on testing in additional preset picture settings, particularly the balance be tween a representative and not overly burdensome test procedure

. (See Issue 4 in section V.E ”Issues On Which DOE Seeks Comment”)

.

2. Testing Order In today’s NOPR, DOE is proposing to require that test ing be conducted in the following order: luminance, on mode power , standby mode power , and off mode power tests. This is not consistent with the test procedure prescribed in ENERGY STAR v. 5.3 , which specifies on mode tests be conducted prior to luminance tests

. DOE is aware that some TVs are unable to operate in the retail picture setting once the TV has been switched into the home picture setting. Therefore , it is necessary to measure luminance in th e retail picture setting before switching to the home picture setting to ensure that the retail picture setting luminance is captured

. For this reason, DOE is proposing to perform luminance testing prior to on mode power testing in section 5.3.1 (l uminance t est) of appendi x H to subpart B of 10 CFR part 430

. DOE does not believe that this alternative testing order will increase the testing burden or cause any issues with test results, but will ensure that all TVs are adequately tested in each prescribed mode

.

3. Luminance50

A lthough IEC 62087

- 20 11 does not include a luminance test, ENERGY STAR v. 5.3 requires a test of the screen luminance. The luminance test is included to ensure that TVs are not shipped in an overly dim picture setting in order to achieve a lower measured on mode power value , since under ENERGY STAR v. 5.3 TVs are tested in “as shipped” condition. In the 2010 RFI, DOE asked interested parties for comments on multiple facets of luminance testing. Specifically, DOE requested input on (a) whether testing luminance should be required, and (b) the different display patterns that can be used to adequately test lumina nce. 75 FR 54048, 54049. Many interested parties provided feedback regarding the need for luminance testing. Several interested parties supported luminance testing. NRDC stated that screen luminance is important to include in the test procedure because it often has a direct impact on TV on mode power use and future energy conservation standards might include these parameters in the rulemaking ; thus, including a test for screen luminance would allow policy makers the ability to add luminance requirements to their standards . (NRDC, No. 5 at p p . 2

- 3 ) It further clarified that the luminance test method should include details on (a) the video signal being used; (b) the type of instrument and its precision; (c) the angle and location of the measurement points; and (d) the ambient lighting conditions, if necessary. (NRDC, No. 5 at p. 5) Finally , NRDC stated that it believe s the DOE luminance testing could require: (a) testing in “as shipped” conditions in home or retail picture settings ; (b) ability to measure eithe r a luminance ratio or a power ratio ; and (c) TVs to be set at a specified luminance prior to measurement. ( NRDC, No. 5 at pp. 3

- 4 )

LG supported the ENERGY STAR luminance test method , which involves measuring the luminance while displaying the IEC 62087

- 20 11 three bar video signal

. This test is conducted twice, once while the TV is in the home picture setting and again when the TV is in the retail picture setting

. After both measurements are taken, the ratio of the two luminance measures is51

calculated . LG believe s that it is an acceptable and representative measure of luminance and provides consistency across state and federal programs. (LG, No. 3 at p. 1) SHARP does not support luminance testing, but asserts that, if DOE must define a luminance measurement procedure, it should follow the ENERGY STAR v. 4.1 (which remained unchanged in ENERGY STAR v. 5.3) test procedure in detail. (SHARP, No. 14 at p. 5) Similarly, Sony believes that the luminance requirement as defined by ENERGY STAR v. 5.3 is an unnecessar y test , but finds the method itself provides a rather simple solution to a complex subject. (Sony, No. 8 at p. 2)

Alternatively, CEA and some manufacturers strongly opposed requiring a luminance measurement, with primary arguments including that default TV picture settings are not too dim, and DOE should not regulate a performance metric. CEA stated that a luminance requirement is unnecessary, premature and essentially not energy related. (CEA, No. 13 at p. 3) CEA also commented that any proposal to impose limits on luminance and/or tie luminance levels to power levels is speculative and a performance requirement should not be embedded within the test procedure as it may not be authorized by EPCA. (CEA, No. 13 at p. 4) Mitsubishi stated that DOE should not s et standards that assure that products meet a certain consumer utility. (Mitsubishi, No. 7 at p. 3) CEA noted that DOE should not include a luminance requirement , but if a luminance test is included it should mirror the test outlined in ENERGY STAR v. 4.1 (which , as noted above, remained unchanged in ENERGY STAR v. 5.3) . (CEA, No. 13 at p. 4) According to CEA , data indicates that consumers maintain the default settings of the TVs , and , therefore, retail picture setting s are not relevant to those consumer viewing habits . (CEA, No. 13 at p. 3) Sony also commented that , after thorough ly review ing its call center data, it found no complaint of dim pictures, which was DOE’s reasoning for including a luminance test. (Sony, No. 8 at p. 1) Sony commented that the test procedure should measure power and should not be a52

luminance test procedure. (Sony, No. 8 at p. 4) Mitsubishi commented that manufacturers will not produce TVs with dim home picture settings , because this would create poor reviews and high return rate s. Mitsubishi further believe s it is undesirable for manufacturers in this industry to sell a TV that is too dim because there are very tight margins. (Mitsubishi, No. 7 at p. 2) Panasonic believes that a regulation on luminance is not required since manuf acturer competition discourages the shipping of dim TVs. (Panasonic, No. 6 at p. 1) Panasonic affirmed that the luminance testing in ENERGY STAR v. 5.3 was adopted as a solution to prevent only the remote possibility of the TVs being shipped too dim. (Pana sonic, No. 6 at p. 2)

SHARP stated that DOE should not specify a luminance measurement and observed that the 65 percent home to retail ratio required by ENERGY STAR specifications may be encouraging TVs to have a brighter home picture setting than they oth erwise would

. SHARP did
not believe that setting a lower bound for luminance would address th e issue of shipping a TV too dim to decrease its power consumption for home mode testing

. (SHARP, No. 14 at p. 3) SHARP wrote that IEC did not set luminance requirements because manufacturers will not ship overly dim TVs and risk product returns . Additionally, SHARP commented that there is no consensus on how to measure brightness levels, and setting a lower bound on home mode brightness is a per formance requirement rather than an energy requirement. (SHARP, No. 14 at p. 2 ) SHARP further noted that if performance requirements force minimum luminance levels to be set too high, potential energy savings are lost. (SHARP, No. 14 at p. 3) Lastly, SHARP commented that any static video signal can be detected and circumvented, and therefore DOE should not implement a luminance measurement. (SHARP, No. 14 at p. 3) It stated th at IEC 62087

- 2008 (which is the same as IEC 62087

- 2011) was not based on prescribe d luminance levels for the following reasons:53

1) Consumers generally do not adjust their TVs from the default settings, 2) Relatively few consumers have their TVs professionally calibrated, 3) There is no consensus on how to measure perceived brightness levels, 4) Perceived brightness is often related to contrast ratio as it is related to pure brightness, 5) Some TV technologies have a non

- linear relationship between power and brightness, 6) Variation in consumer illuminance levels make the ideal brigh tness difficult to determine, and 7) Humans have poor acuity for discerning absolute brightness levels, and there is no data that identifies the level of brightness to which the average person would adjust a television by hand. (SHARP, No. 14 at p. 2)

In this NOPR, DOE is proposing to include a luminance test as part of its test procedure

. In recognition of interested parties’ concerns, DOE clarifies that the proposed luminance test is included in the test procedure solely for the purpose of supporting th e ENERGY STAR program ; the Department is not proposing to include the luminance measurements in its final metrics for measuring the energy efficiency or consumption of TVs . Including a luminance test as part of the test procedure for TVs will allow other programs such as ENERGY STAR to utilize the results

. The sections, below, describe the different aspects of this proposal, as well as comments from interested parties on these aspects.

a. Warm

- up and Stabilization

As mentioned in section III.E.2 , above, DOE is proposing to require that luminance tests be conducted prior to on mode test ing . Due to the change in luminance testing order (con ducting54

testing in the retail picture setting prior to the home mode picture setting) , DOE considered both warming

- up the TV with respect to power and stabilizing the TV for luminance

. However, i n today’s notice , DOE is proposing that the TV be warmed

- up b ut not be stabilized prior to measuring display luminance.

IEC 62087

- 20 11 and ENERGY STAR v. 5.3 both require that the TV be warmed

- up prior to energy measurement but do not include a recommended or minimal time period

. Rather, they state that energy measu rements be taken “after the TV has achieved a stable condition with respect to power consumption.” With respect to luminance testing, ENERGY STAR v. 5.3 requires the three bar video signal be displayed for 10 minutes to stabilize a TV prior to conducting a measurement. DOE received comments from interested parties on the appropriate time required to warm

- up and stabilize a TV prior to conducting testing. 75 FR 54048, 54051

Mitsubishi commented that measurements of power consumption should be taken after the TV has reached normal operating temperature. (Mitsubishi, No. 7 at p. 5) Mitsubishi further commented that warm

- up times vary by model and it is difficult to identify a minimally sufficient warm

- up time, but it is also unnecessary. It continued by adding that it is sufficient to require that before testing begins, the device under test has reached thermal equilibrium, and that the test procedure need not indicate a specific time but rather a minimum. (Mitsubishi, No. 7 at p. 6) PG&E and California IOUs stated that the warm

- up time should be sufficient to reflect real

world conditions while also aiming not to be too long so as to become overly burdensome. (PG&E, No.12 at p. 3; California IOUs, No. 9 at p. 3) SHARP, Sony, Panasonic , and CE A recommended that DOE refer to the IEC 62087

- 2008 test procedure for warm

- up periods. The55

warm - up periods remained unchanged in IEC 62087

- 2011. (SHARP, No 14 at p. 7; Sony, No. 8 at p. 3; Panasonic, No. 6 at p.7; CEA, No. 13 at p. 7)

DOE acknowledges all stakeholder comments and is proposing to incorporate language that the TV be warm ed

- up consistent with that in IEC 62087

- 20 11 , with the addition of a minimum warm - up period requirement. In this NOPR, DOE is proposing TVs be warmed

- up using the IEC 62087

- 20 11 dynamic broadcast

- content video signal for at least one hour in section 5.2 (warm

- up) of appendix H to subpart B of 10 CFR part 430

. DOE conducted testing to determine if this warm

- up was appropriate 14 . Although the power did not change drastically over the one hour for any of the TVs tested, DOE believes that because no interested party commented on the desire to reduce the duration , a one hour warm

- up period was still appropriate. DOE will further propose that the TVs can be warmed

- up for longer than on e hour if the TV does not reach a stable state with respect to power consumption within the one hour time period. DOE is defining a stable state as an average power measurement over the 10 minute test clip that varies by less than 2 percent on consecutive plays. DOE believes that by establishing a minimum warm

- up period, the test results will be more consistent , because all TVs will be warmed up for an identical time period. Further, DOE testing indicates that the majority of TVs will stabili ze within one hour. DOE also consulted with industry subject matter experts 15 who had similar findings 16 . Although DOE plans to specify that a one hour warm

- up period be used,

14 The warm up period data can be found on the DOE website: Appliance and Commercial Equipment Standards: Television Sets . U.S. Department of Energy. August 2, 2011. < http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html > 15 Keith Jones, Managing Director, Australian Digital Testing and Bob Ha rrison, Principal Scientist, UK Government Market Transformation Programme Consumer Electronics and Information and Communication Technologies 16 The stabilization period can be seen to stabilize within one hour based on the data found in the Luminance Period document which can be found on the DOE website: Appliance and Commercial Equipment Standards: Television56

there is flexibility to utilize a longer warm

- up period for the TV to reach a stab le energy consuming state
. For luminance stabilization, DOE is not proposing that th e TV be stabilized prior to conducting luminance measurements , rather that luminance measurements be taken immediately upon displaying the t hree bar video signal

. Luminance measurements are made immediately to prevent automatic image correction programs from revising the luminance of the observed test pattern.

DOE received a comment from Panasonic recommending that DOE a dopt the luminance measurement test procedure in ENERGY STAR v. 5.3 , which requires that luminance be measured immediately following the on mode test, ensuring that the TV is sufficiently stabilized with respect to power prior to conducting the luminance tes t. Panasonic also stated that it does not object to increasing the 10 minute stabilization periods if it is felt to be necessary. (Panasonic, No. 6 at p. 7) No other interested parties commented on the topic.

ENERGY STAR v. 5.3 requires that the TV display the three bar video signal for 10

m inutes prior to conducting a luminance measurement. As part of today’s NOPR , DOE is proposing to require that luminance measurements be taken immediately after displaying the IEC 62087

- 20 11 dynamic broadcast

- content video signal from the warm

- up period in section 5.4.1 of appendix H to subpart B of 10 CFR part 430 . DOE conducted extensive research to determine the appropriate stabilization period and has preliminarily determined that taking luminance measurements immediately after displaying the IEC 62087

video signal is the most technology neutral method 17

. DOE ’s research also found that the luminance of some TV technologies drops as the same image remains on the screen and luminance with other TV technologies increases as the same image remains on the screen 18

. T aking an immediate measurement helps to mimic actual operating conditions, in which images are changing constantly.

Specifically, t aking measurements according to this method ensures that TVs, particularly plasmas, do n ot enter into an automatic brightness limiting (ABL) state prior to luminance testing. ABL is a technology that is used on phosphor based TV screens (CRT and plasma ) that is designed to limit the luminance of the screen to a level that will avoid damage to the phosphor s. This type of protection i s not necessary in LCD technology as high luminance levels cannot cause damage to the display elements. Measuring the luminance immediately after displaying the I EC 62087

- 20 11 dynamic broadcast

- content video signal , without allowing a substantial period of delay, will ensure that TVs do not require additional stabilization time while displaying the IEC 62087

- 20 11 three bar video signal which would result in some TVs entering

an ABL state. This method will promote mo re consistent testing across products. Taking measurements according to this method also ensures that TVs, particularly LCDs with cold cathode fluorescent lamp (CCFL) technology , have been stabilized

. DOE welcomes comments on the stabilization and warm

- up periods proposed in this NOPR. (See Issue 6 in section V.E ”Issues On Which DOE Seeks Comment”)

.

b. Method for Testing Luminance
As mentioned above, many TVs have m ultiple preset viewing settings . Again, the retail picture setting is typically used in showrooms, whereas the home picture setting is intended to be more suited for typical home viewing conditions. ENERGY STAR v. 5.3 uses a luminance ratio test that compa res these two picture settings . However, DOE is aware of alternative methods for ensuring that the TV does not have an overly dim home picture setting such as power ratios and absolute luminance measurements, and therefore in the 2010 RFI, DOE requested feedback on testing by using luminance ratios, power ratios and absolute luminance. 75 FR 54048, 54049.

Many commenters believed that power cannot be measured to determine the brightness of the TV. Panasonic commented that the relationship between power an d luminance is often non

linear and is highly variabl e between TV technologies, specifically in TVs with "local dimming" and "power on demand"

. Panasonic believes that this non

- linear relationship makes a power ratio an unfair measurement of screen brightn ess. Panasonic believes that the measurement of the power would not result in the goal of determining whether a TV is "too dim.” (Panasonic, No. 6 at p. 2) Panasonic commented that though they recognized all of DOE’s concerns pertaining to a luminance rati o, they support its inclusion in the test procedure. (Panasonic, No. 6 at p. 2) Mitsubishi commented that different display technologies have different luminance and power characteristics , and these two aspects of TVs should not be conflated . Mitsubishi al so noted that luminance variation across the screen is unrelated to energy consumption. (Mitsubishi, No. 7 at p. 2) Mitsubishi also believes that measuring power rather than a luminance ratio does not satisfy the "goal" of preventing manufacturers from pro ducing devices that are not useful in the home picture setting . (Mitsubishi, No. 7 at p. 3) Finally, Mitsubishi commented that some TV display59

technologies have a power consumption that correlates significantly with the content displayed rather than the di splay luminance. (Mitsubishi, No. 7 at p. 3) SHARP stated that a fixed luminance level is not prescribed for power measurements made with CEA

- 2037

- 2009 and IEC 62087

- 2008 (nor in IEC 62087

- 2011) , and therefore DOE does not need to implement a luminance mea surement. (SHARP, No. 14 at p. 3) Sony also does not support measuring power consumption at prescribed luminance levels or picture settings . Sony believes that picture settings are performance settings and are not directly tied to luminance. (Sony, No. 8 a t p. 2)

CEC presented an alternative method for using power to ensure the TV is not shipped in an overly dim picture setting . CEC suggested that a power ratio be taken between home and retail picture settings

. T he home picture setting would be used for com pliance when the ratio was closer to one , while a weighted result of home and retail picture settings power would be used as the power deviates from one . (CEC, No. 15 at p. 2) NRDC suggested that DOE improve the ENERGY STAR luminance test by establishing a minimum screen luminance for all presets in the set up menu. The method would require the lab technician to record the screen brightness that was measured prior to running the on mode power test with the IEC 62087

- 2008 dynamic broadcast

- content video sign al , which is the same as the IEC 62087

- 2011 dynamic broadcast

content video signal. (NRDC, No. 5 at p. 4) NRDC also urged DOE to ensure that all measurements for ratios should be made identically. (NRDC, No. 5 at p. 5)

SHARP also suggested an alternative m ethod for ensuring that TVs are shipped in a picture setting that satisfies consumer viewing desires. SHARP commented that DOE should set a requirement based on a “floor,” which would be a fixed percentage of the power of the most consumptive setting , and recommends that the floor be 40 percent of the most power consuming60

setting. This approach will help ensure that home picture setting is not overly dim as well as cap the maximum power consumption of a TV regardless of the picture setting . (SHARP, No. 14 a t p. 5) SHARP supports the maximum power ratio approach, given that the allowable home to retail picture settings power ratio is no more than 40 percent. SHARP believes that unlike the luminance ratio approach, which is a performance requirement, setting a threshold for reported power is part of the power measurement process. (SHARP, No. 14 at p. 3) P.R. China suggests implementing an efficiency ratio of the output power and input power that includes luminance in the nominator, multiplied by the screen size , and divided by the input power. (China, No. 16 at p. 3)

PG&E, California IOUs , and CEC requested a flexible test procedure with respect to luminance. PG&E and Calif ornia IOUs recommended that the test procedure be designed so that policy

- makers could con sider luminance or power ratios between different preset picture settings . (PG&E, No.12 at p. 2; California IOUs, No. 9 at p. 2) CEC urged DOE to adopt a test procedure which includes both power and luminance testing at a minimum picture setting and the

re tail picture setting , but provide s enough flexibility that the policy makers can decide how these numbers are used to set standards. (CEC, No. 15 at p. 2)

Interested parties also offered comments discouraging the possible inclusion of an absolute luminance measurement. Panasonic believes that absolute luminance does not provide enough data to determine if the TV is providing a "satisfactory consumer viewing." Panasonic noted that many TV c a lib rat ors and video post production engineers consider the contrast ratio to be more important than absolute luminance. (Panasonic, No. 6 at p. 2) Panasonic also commented that when measuring luminance, the method must provide accurate results across all61

technologies, which is much easier with a ratio than with absolute lu minance measurements. (Panasonic, No. 6 at p. 2) Finally, Panasonic commented that using a relative ratio is more tolerant of non

- calibrated luminance meters, measurement distances and angles and the measurement location because the error cancels out betwe en the two measurements. (Panasonic, No. 6 at p. 3)

In this NOPR, DOE is proposing measuring luminance to allow the ENERGY STAR program to utilize the measurement in section 5.3.1 (luminance test) of appendix H to subpart B of 10 CFR part 430

. As mentione d in section III.E.1 above, DOE is proposing to test the TV in home and retail picture settings

. DOE is proposing to include a luminance ratio, as is done in ENERGY STAR v. 5.3. DOE believes t hat by taking a ratio, less error is introduced than if taking a n absolute luminance measurement . Further, ratios have been used in many other TV efficiency measures

. For example, ENERGY STAR v. 5.3 re quires that home picture se tting shall not be less than 65 percent of the peak luminance of the retail picture setting

. The European Parliament requires a luminance ratio of at least 6 5 percent in the Commission Delegated Regulation (EU) No 642/2009

. Austr alia’s government requires a 50 percent luminance ratio in AS/NZS 62087.2.2:201

. Although DOE does not currently intend to include the luminance
measurements in its final metric s for measuring energy efficiency or consumption , testing for a luminance ratio will allow DOE’s TVs test procedure to support the requirements of the ENERGY STAR Program and allow other regulating bodies to include a luminance ratio in their test procedures

. DOE invites comments on luminance testing and including a luminance ratio. (See Issue 5 in section V.E ”Issues On Which DOE Seeks Comment ”)

.62

c. Video Signals
To test luminance, ENERGY STAR v. 5.3 requires that a static video signal be disp layed, and a measurement be taken using an LMD. In the 2010 RFI, DOE asked for comments on the use of two video signals: the IEC 62087

- 2008 three bar video signal , which is the same as the IEC 62087

- 2011 three bar video signal, and the Chinese TV test proc edure’s nine point video signal (hereafter referred to as the nine point video signal). 75 FR 54048, 54050. As mentioned, IEC 62087

- 20 11 does not require luminance testing, whereas ENERGY STAR v. 5.3 requires that a single luminance measurement be taken wh ile the TV is displaying the three bar video signal.

DOE believes that an ideal TV luminance video signal should represent actual broadcast content as closely as possible so that the measured luminance is an accurate reflection of the luminance produced under real

- world operating conditions and is technology

- neutral. DOE recognizes that it is possible that an ideal video signal may vary depending on the purpose for which it will be used

. DOE envisions that the three bar luminance video signal proposed in today’s NOPR would be used as part of a luminance ratio. The table below lists the various video signals th at DOE is considering as well as their perceived advantages and disadvantages. It should be noted that a number of stakeholder comments appear to equate the number of white areas in the video signal with the number of measurements. DOE wishes to clarify th at these are two separate issues (for example, the nine point video signal could be used to test at anywhere between one and nine points); the number of measurements and related test burden are discussed in a following section. Any of the following video s ignal s could be measured at a single point or multiple points.63

Three key features of plasma TV technology impact the brightness of white areas on their screens. These features, therefore, need to be taken into consideration in evaluating and selecting

an appropriate technology

- neutral video signal . Most p lasma technology TV s limit brightness for very bright parts of the screen. As mentioned above, t his feature called ABL is intended to protect the screen

. Although the intention of ABL is to protect the scr een, ABL functions differently across TVs. The protection is, however, generally based on the size of the bright area. For very small areas such as tiny spots seen on firework displays, ABL is likely to have little effect and the spots, therefore, will be very bright. The larger the white area, the more ABL tends to be applied. The second type of protection is when a static picture is detected with bright (and maybe not so bright) areas. After several minutes of a static image the brightness may be decrease d to try to eliminate phosphor image burn. The third protection mode operates when the whole screen is bright: to protect plasma drive circuits , the power , and thus also the luminance , tend to be limited. What is being observed is the image burning protection.

DOE recognizes that none of the video signals currently under consideration is ideal

. Each has advantages and disadvantages which are described below. Until a markedly improved vi deo signal is made available, DOE is not inclined to change the status quo. DOE understands that IEC is contemplating a pattern with a dynamic video signal which may have significant advantages. DOE supports IEC’s development of this potentially improved p attern and would consider incorporating it in future TV test procedures

DOE received comments on each of the video signals (see sections, below), described above as well as alternative suggestions for luminance testing, including the number of measurements to take while displaying a particular video signal. In response to commenters ’ concerns, DOE considered multiple video signals when developing its NOPR. DOE considered the three bar, the nine point, and a DOE developed dynamic video signal . In this NOPR, DOE is proposing to test luminance using the three bar video signa l in section 5.3.1.2 (three bar video signal measurement) of a ppendix H to subpart B of 10 CFR part 430 , but is also considering using the other two signals.

i. Three Bar Video Signal The three bar video signal was developed by the IEC and published in the third edition of its TV broadcast transmission test procedure, IEC 60107

- 1997 E d. 3 .0 “ Methods of measurement on receivers for TV broadcast transmissions

- Part 1: General considerations

- Measurements at radio and video frequencies

. ” The three bar video signal is found in IEC 62087

- 2011 , and is used to measure lumina nce in ENERGY STAR v. 5.3. It is the most widely used video signal for measuring luminance. The three bar video signal produces three equidistant vertical white bars on a black background. The width of each of these bar s is 1/6 of the nominal horizontal wi dth of the picture

. The three bar video signal has an APL of 50 percent. A high er APL can cause some plasma TVs to enter more quickly into a power limiting state to prevent screen burn

- in caused by displaying a bright screen for an extended period of time.

In response to the 2010 RFI, many commenters expressed desire for DOE to u s e the three bar video signal for testing luminance. CERC, CEA, Sony, Mitsubishi , and Panasonic supported66

the use of the three bar video signal. (CERC, No. 10 at p. 3; CEA, No. 13 at p. 4; Sony, No. 8 at p. 2; Mitsubishi, No. 7 at p. 3; Panasonic, No. 6 at p. 3) Mitsubishi believes that the three bar video signal is adequate. (Mitsubishi, No. 7 at p. 4) Sony commented that t he 3

- bar test pattern is used in IEC and ENERGY STAR test p rocedures. Changing it will add complexity to an already complex subject. (Sony, No. 8 at p. 2) CEA stated that DOE should institute the ENERGY STAR test method of using the three

- bar measurement procedure. (CEA, No. 13 at p. 4) Panasonic supports the use of the 3 bar pattern, as it is used by ENERGY STAR, CEA, CEC, and Australia. (Panasonic, No. 6 at p. 3)

Conversely , SHARP commented that the three bar video signal is ineffective for p lasma TVs, giving an advantage to the technology and is not necessarily “ unpredictable for LED backlit TVs, ” as DOE stated in the 2010 RFI. (SHARP, No. 14 at p. 4)

Although DOE is proposing that luminance testing be conducted with the three bar video signal , DOE acknowledges that there are drawbacks associated with its use

. T he APL of the three bar video signal is 50 percent, which is greater than that of typical broadcast content
. The three bar video signal also does not have a reference point to vertically center the luminance meter readings which requires additional time to establish where the measurement should be taken. Another drawback to the three bar video signal is a static video signal which is not

re presentative of typical TV program content. The final disadvantage to the three bar video signal is that it results in a quick ABL for plasma TVs due to the amount of white space on the

screen. Although, the three bar video sign al has disadvantages, DOE is currently unaware of a truly technology neutral video signal that isn’t affected by the type of TV technology. Video signals can have differing affects on TV technologies resulting in higher power consumption in67

some technologi es and lower power consumption in other technologies. Because the three bar video signal is the current industry standard, it is used as a basis for comparison for the other video signals considered in the sections below.

ii. Nine Point Video Signal The nine p oint video signal is used in the Chinese TV test procedure ICS 27.010 . The video signal was developed to measure variations in luminance across the screen and account for local dimming. This video signal consists of nine white rectangular boxes symmetrical ly arranged in a three by three grid. The nine point video signal is also a static video signal which does not improve upon the current three bar video signal and can also result in some ABL for plasma TVs. The average APL for the nine point video signal i s 17 percent which is lower than typical broadcast content

. (P.R. China, No. 16 at p. 3) Because the nine point video signal has a lower APL than the three bar video signal , it alters the luminance ratio between home and retail picture settings for some TV s which would force policy makers to alter their respective luminance ratio requirements. DOE found that at least four different plasma TVs , which would have met ENERGY STAR requirements for luminance ratio with the three bar video signal , had a ratio belo w 65 percent when displaying the nine point video signal.

Panasonic discouraged DOE from using the nine point video signal and Digital Video Essential ( DVE ) window (a VESA industry video signal ) because Panasonic believes these patterns do not prevent some TVs from power limiting; therefore they are not technology neutral. Panasonic did not provide any comment on how the video signal s impact the TV’s power limiting. (Panasonic, No. 6 at p. 4)68

Alternatively, P. R. China recommended that D OE utilize the nine point video signal because the APL is 17 percent, it is technology neutral, and it accounts for non

- uniform screen luminance. (P.R. China, No. 16 at p. 3)

DOE conducted various test s utilizing the nine point video signal. After interpre ting data, the absolute luminance values obtained while using the DOE nine point video signal were generally higher in the retail picture setting and lower in the home picture setting than those obtained while using the three bar video signal, particularly in plasma TVs. DOE believes these results can be attributed to the lower APL of the nine point video signal, which prevents the TV from quickly entering ABL

. This video signal might than disproportionately disadvantage plasma TVs. DOE also determined that changing the video signal will also impact the luminance ratio. Due to the change in absolute luminance values obtained while using the DOE nine point video signal, luminance ratios generally decreased for plasma TVs when compared to displaying the three bar video signal

. DOE did not find any other major trends in size or brand for the TVs in which the ratio differed when using the nine point video signal as opposed to the three bar video signal

. Due to the reasons stated above, DOE has determined not to p ropose utilizing the nine point video signal in this NOPR.

iii. DOE Five Point Video Signal As mentioned above, DOE developed a five point video signal that has an APL identical to typical consumer broadcast content (34 percent). This video signal is based largely on the VESA five point video signal and consists of five white rectangular boxes arranged with one box in the center of the screen and one box in each corner .69

Upon testing, DOE found that the absolute luminance values obtained while using the DOE f ive point video signal were generally lower than those obtained while usi ng the three bar video signal. DOE believes these results are due to the fact that the five measurements took into account the perimeter of the screen which is typically dimmer than t he center. Similar to the nine point and the VESA five point video signal, this can also be attributed to the location of the measurements taken, as the center of the screen is typically brighter than the edges. With testing, DOE determined that this video signal also displayed some ABL for some plasma TVs regardless of the fact that the APL is 34 percent. DOE did not find any major trends in size or brand for the TVs in which the ratio differed when using the DOE five point video signal as opposed to the t hree bar video signal other than change s in the luminance ratio for some TVs.

iv. DOE Dynamic Video Signal Finally, DOE is interested in the development of a video signal that it believes may be more representative of actual consumer use, and may be more techn ology neutral. A technology neutral video signal was requested by numerous interested parties in response to DOE’s 2010 RFI

.

S ome interested parties expressed a general desire for a technology neutral video signal or one that has an APL more similar to th e IEC 62087

- 2008 dynamic broadcast

- content video signal , which is the same as the IEC 62087

- 2011 dynamic broadcast

- content video signal

. PG&E and California IOUs encouraged DOE to develop a video signal that has an APL that is more similar to the IEC 62087

- 2008 dynamic broadcast

- content video signal than the three bar video signal. This will help ensure that the luminance measurements are more reflective of actual TV usage. (PG&E, No.12 at p. 2; California IOUs, No. 9 a t p. 2) PG&E and the California IOUs also70

commented that the video signal should not favor one type of display technology over another. (PG&E, No.12 at p. 2; California IOUs, No. 9 at p. 2 ) Panasonic agree d t hat the goal of a technology neutral video signa l is certainly appropriate, though they feel that such a pattern has been elusive. (Panasonic, No. 6 at p. 3) NRDC encourages DOE to track the IEC development effort that is in progress, because IEC may be considering a potentially more technology neutral video signal including the nine point video signal used in China . (NRDC, No. 5 at p. 4) Finally, CEC supported DOE’s investigation to identify a suitable video signal and recommends one that has an APL close to that of the IEC 62087

- 2008 dynamic broadcast

- content video signal. ( CEC, No. 15 at p. 2) P. R. China agrees that an alternative video signal with an APL more similar to the IEC 62087

- 2008 dynamic broadcast

- content video signal should be developed. ( P.R. China, No. 16 at p. 3) P.R. China suggests that TVs be adjusted using the “8

- gray scale mode” and then be tested using the nine point video signal. ( P.R. China, No. 16 at p. 3)

Panasonic also suggested alternative language found in the EuP 642/2009 20 to conduct luminance testing. T he EuP 642/2009 allow s for different video signals for various TV technologies and only specifies that the video signal must be a “ full screen,” which does not exceed the APL point where power limiting occurs. (Panasonic, No. 6 at p. 3) Panasonic commented that the European Un ion recognizes that each technology has a different, non

- linear methodology for determining the brightness of individual images and therefore has prescribed different video signals for various technologies to meet the criteria of having a video signal that is not "power limiting" or dimming the screen as more pixels are required to be illuminated.

20 Directive 2005/32/EC of the European Parliament and of the Council with regard to ecodesign requirements for televisions < http://eur

- lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2009:191:0042:0052:EN:PDF >71

Panasonic believes that both of these methods are also valid approaches of measuring luminance. (Panasonic, No. 6 at p. 3)

Alternatively, Mitsubishi commented th at the APL is irrelevant to the goal of measuring luminance, which is to determine if the home picture setting luminance is overly dim. (Mitsubishi, No. 7 at p. 3)

To address interested party comments, DOE ’s subject matter experts 21 have recommended development of a video signal that simulates the apparent brightness of a picture as well as an APL similar to the IEC 62087

- 20 11 dynamic broadcast

- content video signal

. The proposed video signal would consist of a black rectangle (with an APL of zero perc ent) and a white rectangle (with an APL of 100 percent) placed at the center of the IEC 62087

- 2008 dynamic broadcast

- content video signal

. These rectangles will maintain the video signal’s APL at approximate ly 34 percent, which is similar to typical broadc ast content. Each rectangle would be approximately 1 x 1 inch for a 26 inch TV. The purpose of the small size of the rectangles is to minimize the overall impact they have on the APL of the video signal but allow for a white section to measure the luminanc e . Also , to help ensure that the TV does not detect the squares as stationary objects, the squares will alternate places with each other every minute.

DOE hopes that this video signal will not unfairly benefit any specific technology, because it will simul ate the state that the TV enters when displaying the IEC 62087

- 20 11 dynamic broadcast

- content video signal. This video signal may also prevent the TV from APL ,

21 Keith Jones, Managing Director, Australian Digital Testing and Bob Harrison, Principal Scientist, UK Government Market Transformation Programme ICT and CE products72

because it is a dynamic video signal which neither the three bar nor nine point video signal are capable of preventing.

In summary, DOE understands the issues associated with the three bar video signal as well as all static video signals , but is utilizing the three bar video signal as the tentative default video signal for this NOPR while it continue s to investigate other video signals and receive comments about them. Although DOE is proposing to require the three bar video signal , it would
apprec iate any comments on measuring luminance while displaying either the nine poin t or dynamic video signal that DOE also considered for incorporation in this rulemaking. (See Issue 7 in section V.E ”Issues On Which DOE Seeks Comment”)

.

d. Number of Luminance Measurements
In addition to the particular video signal displayed during luminance testing, the number of measurements and how those measurements are taken is important. In the 2010 RFI, DOE asked for comments on a nine point test measurement versus a single point test measurement . 75 FR 54048, 54050. Given the interest ed party feedback and additional testing discussed below , DOE is proposing to only require a single point luminance measurement.

In response to the 2010 R FI, many commenters expressed desire for DOE to only require one luminance measurement if a luminance measurement is required . Mitsubishi stated that the variation of luminance across the screen, which they beli e ve is the purpose of measuring multiple poin ts while displaying the nine point video signal , does not relate to the goal of ensuring that TVs do not have a home picture setting that is overly dim. Mitsubishi added that,73

for this reason, taking nine measurements using the nine point video signal adds unnecessary burden. (Mitsubishi, No. 7 at p. 4) Sony believes that using a video signal other than the three bar video signal and measuring multiple points will add complexity to an already complex subject. (Sony, No. 8 at p. 2) Panasonic commented that t he nine point video signal offers no benefit over the three bar video signal, noting that a nine point s measurement requires more time, is more difficult to perform, and is less repeatable. (Panasonic, No. 6 at p. 3) Sony similarly stated that manufacturer s in China suggested that measuring luminance while utilizing the nine point video signal is lengthy and complex when measuring multiple points , and it does not provide more meaningful energy information than measuring a single point, though Sony did not e xplicitly state which Chinese manufacturers provided this comment. (Sony, No. 8 at p. 2) CEA also strongly opposed replacing the single point luminance measurement with the nine point video signal measurement , because taking nine measurements adds burden w ithout giving more meaningful results. (CEA, No. 13 at p. 5) SHARP believes that a single point measurement is adequate for a ratio test. SHARP added that the Chinese test procedure uses a nine point video signal since it outputs an absolute luminance. (SH ARP, No. 14 at p. 4) SHARP commented that a nine point video signal measurement is much more expensive than a single, centered measurement. (SHARP, No. 14 at p. 4)

Other commenters urged DOE to adopt a luminance test that required multiple measurements, rather than a single measurement as currently required in ENERGY STAR v. 5.3

. PG&E and California IOUs recommended DOE collect and analyze data using multiple point video signals to account for variations of luminance levels on different areas of a screen. (PG&E, No.12 at p. 2; California IOUs, No. 9 at p. 2) PG&E and California IOUs acknowledged that adding a multiple measurement video signal will add test variation; however, they believe that74

luminance measurements from multiple points may be needed. (PG& E, No.12 at p. 2; California IOUs, No. 9 at p. 2) NRDC did not specify a particular video signal to be used, but they prefer a method that requires multiple measurements rather than a single measurement. (NRDC, No. 5 at p. 4)

DOE conducted testing with the nine point video signal in order to determine the drawbacks and benefits of measuring luminance at multiple locations compared to measuring at only one point . Testing using this video signal was conducted using two separate methods: 1) perpendicularly re a ligning the LMD to the center of e ach of the nine white squares ( hereinafter referred to as the DOE nine point method) ; and 2) aligning the LMD perpendicularly with the center white square, maintaining the LMD fixed position, and angling the meter to measu re eight off

- axis white squares ( hereinafter referred to as the Chinese nine point method). A distance luminance measurement is required to test off

- axis measurements , but both a distance and contact meter can be u sed to take the perpendicular measurements . These nine measurements can be averaged to arrive at the overall screen luminance, ensuring that the brightness across the entire screen is accounted for in the measurement. Although the results for individual points varied across the screen when measuri ng luminance at multiple locations, DOE notes that measuring the additional locations woul d not impact the luminance ratio as the ratio would remain similar between TVs. DOE found that each of the individual measurement points across the TV screen maintain ed a similar ratio in the home and retail picture setting

. DOE therefore believes that its proposed method of measuring luminance at a single location is sufficient for this test procedure. DOE’s test results show that the ratio from the average of the nin e locations and only the central location are exactly the same on all but one TV tested which had ratios that75

were within three percent 22

. Because luminance is calculated as a ratio, multiple location
measurements serve to decrease the measurement accuracy and repeatability of measurement.

In summary, DOE is proposing that only one luminance measurement be taken in each home and retail picture setting in section 5.3.1.2 (three bar video signal measurement) of appendix H to subpart B of 10 CFR part 430 . Taking multiple measurements , specifically with a distance meter, greatly increases the test burden and this burden outweighs the potential benefits of measuring multiple locations around the screen. Measuring only one location will also harmonize the DO E test procedure with other TV test procedures that manufacturers currently use to evaluate products. Although DOE is proposing to only require one luminance measurement per picture setting, DOE is seeking comments on taking a single measurement

versus mul tiple measurements when testing for luminance , along with any testing data that supports or refutes DOE’s proposed method

.

e. Measurement Distances and Angles for Luminance Testing In the 2010 RFI, DOE considered requiring that luminance measurements be take n at various distances and angles , rather than perpendicular to the center of the screen as required by ENERGY STAR v. 5.3. 75 FR 54048 , 5405 0

. However, after further investigation and input from interested parties, DOE is proposing that luminance measurem ents be taken perpendicular to the center of the screen , similar to the approach in the ENERGY STAR test procedure.

22 The luminance ratio data indicates that the ratio from any one particular location (regardless of location) is similar between home and retail settings. This data can be found on the DOE website: Appliance and Commercial Equipment Standards: Television Sets . U.S. Department of Energy. August 2, 2011. < http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html >76

PG&E and California IOUs believe that the angle needs to be specifically defined and that a perpendicular angle may be appropriate; they als o recommend that DOE acquire test results using different angles to inform the decision. (PG&E, No. 12 at p. 2; California IOUs, No. 9 at p. 2) Sony questioned the need to measure at angles and the benefits it provides in a test procedure, stating that the optimal distances to take luminance measurements are described in the LMD specifications. (Sony, No. 8 at p. 2) Similarly, Panasonic recommended that a single luminance measurement be taken perpendicular to the center of the screen. (Panasonic, No. 6 at
p . 4) They believe that the contrast will vary with the room ambient light and the viewing angles. (Panasonic, No. 6 at p. 2) CEA also stated that the measurement distances and angles are not as important as making the measurements in a consistent manner. ( CEA, No. 13 at p. 5) P.R. China measures luminance from a distance of three times the height of a high

- definition TV screen and four times the height of a standard display TV screen because it simulates consumer viewing conditions. (P.R. China, No. 16 at p. 4) Finally, SHARP commented that luminance measurements at various distances and angles would only be appropriate if absolute lumin ance measurements were the goal. (SHARP, No. 14 at p. 4) SHARP also commented that a perpendicular measurement is adequate, if a luminance measurement is required. (SHARP, No. 14 at p. 4) SHARP stated that the correct distance for the measurement is dictat ed by the measurement tool, rather than the TV . (SHARP, No. 14 at p. 4)

Taking nine perpendicular measurements using a distance measure greatly increases testing burden as it requires that the meter be aligned nine times, once for the measurement of each w hite square. The Chinese nine point method also increased burden as it requires nine measurements rather than a single one. Although the luminance meter only needs to be77

positioned once, the additional off

- angle measurements still increase the burden of th e test method. In addition, the Chinese nine point method eliminates the ability to use a contact LMD

.

As stated, above, DOE is proposing that luminance measurements be taken perpendicular to the center of the screen in section 5.3.1.1 (LMD setup) of appen dix H to subpart B of 10 CFR part 430 . DOE believes that measuring multiple locations on off

- axis angles will add unnecessary variation to measurements made, will likely reduce the repeatability of the test and increase testing time. DOE is also proposing that the distance for which these measurements are taken are in accordance to the set specifications for the luminance measurement device , which can be found in III.D.1.c.ii of this NOPR.

4. On Mode DOE is proposing to use the IEC 62087

- 2011 on mode test procedure. This test procedure displays the widely accepted IEC 62087

- 20 11 dynamic broadcast

- content video signal while the TV is in the on mode. Consistent with ENERGY STAR v. 5.3, DOE is considering testing on mode differently depending on whether ABC is enabled or disabled when the TV is shipped. If the TV is shipped with ABC enabled by default, the TV w ould be tested at multiple room illuminance levels, and if the TV is without ABC enabled by default , it would only be tested in the home picture setting. However, DOE wishes to continue to encourage manufacturers to ship TVs with ABC enabled. Although DOE is proposing to measur e on mode without being connected to the internet, DOE is also interested in receiving feedback on potentially measuring on mode while the TV is connected to the internet

. See section 11 of this NOPR.78

a. IEC 62087

- 20 11 Dynamic Broadcast

- Content Video Signal

IEC 62087

- 20 11 and ENERGY STAR v. 5.3 both require the use of the IEC 62087 dynamic broadcast

- content video signal for on mode testing , which is the same in both the 2008 and 2011 versions of the test procedure . This video signal displays a variety of clips that have an
average APL equivalent to typical broadcast content. DOE received a comment from NRDC supporting the use of the IEC 62087

- 2008 dynamic broadcast

- content video signal. (NRDC, No. 5 a t p. 2) Alt hough no other interested party explicitly stated that the IEC 62087

- 20 11 dynamic broadcast

- content video signal should be incorporated , no interested party opposed the use of the video signal. Moreover, a number of parties suggested that the c lip should be the basis for any 3D test procedure, affirming its wide acceptance

. In this NOPR, DOE is proposing that the IEC 62087

- 20 11 dynamic broadcast

- content video signal be used to measure on mode energy consumption in 2D mode on all TVs

.

b. Testing o f Television Sets Shipped with Automatic Brightness Control Enabled
ABC is a power saving feature in which the TV automatically adjusts the screen luminance to account for the ambient lighting conditions (room illuminance). IEC 62087

- 20 11 and ENERGY STAR v. 5.3 require TVs with ABC enabled by default to be tested differently than those without ABC enabled by default. DOE requested comment on the method for testing TVs with ABC enabled by default, as well as which room illuminance levels are most appropria te for testing. 75 FR 54048, 54050.

Interested parties were generally in support of DOE adopting a test procedure for TVs with ABC enabled by default. PG&E and California IOUs commented that appropriate79

implementation of an ABC feature for TVs could result in significant energy savings. (PG&E, No. 12 at p. 2; California IOUs, No. 9 at p. 2) PG&E and California IOUs urged DOE to adopt a repeatable and representative method for measuring energy consumption of TVs with ABC enabled by default, stating that this should be a key area of focus for DOE. (PG&E, No. 12 at pp. 2

- 3; California IOUs, No. 9 at p p . 2

- 3) PG&E and California IOUs have observed that the on mode power consumption reported to EPA drops by an average of 24 percent when testing with the ABC featu re enabled. They obtained this data by comparing 18 specific TV models that did not have the ABC feature enabled on the August 2010 EPA product list , but did have it enabled on the September 2010 list. (PG&E, No. 12 at p. 3; California IOUs, No. 9 at p. 3) NRDC also supported the inclusion of a method to test TVs with ABC enabled by default, stating that when designed properly, the ABC feature can provide low cost means of delivering significant energy savings. (NRDC, No. 5 at p. 5) NRDC further comment e d t hat many TVs have ABC as a means to comply with the new, more stringent ENERGY STAR 4.1 specifications as well as standards in California and elsewhere that are also likely to be effective soon. (NRDC, No. 5 at p. 5) Sony commented that the IEC 62087

- 2008 and ENERGY STAR v. 4.1 use the proper method to measure ABC energy consumption, and in the absence of a better method, DOE should adopt the same method. (Sony, No. 8 at pp. 2

-- 3) This same method is used in IEC 62087

- 2011 and ENERGY STAR v. 4.3

. SHARP be lieves that ABC scaling factors should continue to encourage adoption of a default

- on ABC feature. (SHARP, No. 14 at p. 6) Panasonic commented that due to tremendous variability between TV manufacturers and individual models, it is difficult to measure the performance of the ABC features of TVs. (Panasonic, No. 6 at p. 5) Finally , CEA informed DOE that it will consider changes to ABC testing in the next revision of CEA

- 2037

- 2009 and will propose any change to DOE. (CEA, No. 13 at p. 6)80

DOE agree s with the i nterested part ies that are in support of incorporating TVs with ABC enabled by default in a test procedure . Although some interested parties disagree with the current method of measuring ABC energy savings, the majority of them agreed that testing TVs with ABC enabled by default was appropriate

. DOE therefore is proposing to incorporate a test procedure for TVs with ABC enabled by default in section 5. 4 (on mode test for TVs without ABC enabled by default) of appendix H to subpart B of 10 CFR part 430

. The sections below provide details relating to room illuminance levels and the method for creating test room illuminance for purposes of measuring energy consumption of TVs enabled with ABC

.

i. Test Room Illuminance Levels and Associated Television Luminance Levels

ENERGY STAR v. 5.3 and IEC 62087

- 20 11 require that ABC energy consumption be measured at two test room illuminance levels, 0 lux and greater than 300 lux. As mentioned in the 2010 RFI, a 2009 study conducted by Ecos Consulting discovered that ABC is often implemented in a manner that may not take full advantage of the potential energy savings 23

. In particular , if implemented incorrectly, ABC may achieve significant energy savings at the expense of TV picture quali ty, reducing the likelihood that users will actually enable the feature and achieve the claimed energy savings. The study showed that some TVs reduce the brightness of their displays at 0 lux, and then increase the brightness significantly at room illumina nce levels only slightly above 0 lux. Since both IEC 62087

- 20 11 and ENERGY STAR v. 5.3 only measure energy consumption at the mentioned two luminance levels , the TV seems to consume less energy than it does in use, causing results that are not representati ve of actual use. DOE also

performed testing with respect to this issue and rarely observed any kind of gradual change in

screen luminance in response to changes in room illuminance 24

.
DOE conducted testing in mid

- 2011 on multiple TVs representing various manufacturers, display technologies, and screen sizes to understand how TV luminance varies with changes in room illuminance when ABC is enabled. These measurements largely confirm those recently conducted by t he Collaborative Labeling and Appliance Standa rds Program ( CLASP 25 ) , revealing that some TVs increase their screen luminance in a steady, continuous fashion as

room illuminance increases (models D and L in 1 below ).

DOE ’s testing shows that o ther TVs with ABC operate in a more binary fashion (models K and M in 1 below), holding luminance largely constant until room illuminance becomes quite low, and then dropping their luminance dramatically . This behavior is likely a consequence of the way ENERGY ST AR currently provides an energy savings credit to TVs with ABC enabled by default, since ENERGY STAR currently only measures at 0 and 300 lux, and not at any intermediate points.

24 The energy consumption at different illuminance levels while ABC is enabled can be found on the DOE website: Appliance and Commercial Equipment Standards: Television Sets .

August 2, 2011. < http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html > 25 Jones, Keith, Analysis of Television Luminance and Power Consumption , CLASP, August 2011 , < http://www.clasponline.org/en/ResourcesTools/Resources/StandardsLabelingResourceLibrary/2011/Anal ysis

Sample data from DOE’s testing are shown in 1 . DOE has provided the full data set for this testing on its website 26

.
Figure 1 : Screen Luminance at 0, 10, 30, 50, 100, 150, and 300 lux

DOE has also determined that a significant number of TVs that currently implement ABC do so in a way that yields unusually low screen luminance values (less than 50 nits) when room illuminance is at 10 lux or less. Display experts recommend a minimum luminance for dark room

26 The energy consumption comparison when ABC is on and off can be found on the DOE website: Appliance and Commercial Equipment Standards: Television Sets . U.S. Department of Energy. August 2, 2011. < http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html >83

viewing con ditions of approximately 80 to 137 nits. 27 Very low luminance levels help to reduce energy consumption, but may yield a display that is so dim that users would want to disable ABC or modify room lighting conditions in order to cause the display to operate a t a higher luminance level. In either case, much of the desired energy savings from ABC operation would be lost.

As a result, DOE is seeking comment from stakeholders regarding whether there should be a limit to the reduction in display luminance achieve d from ABC , and how a minimally acceptable display luminan ce value should be established. DOE also received a number of comments on the appropriate room illuminance levels at which to conduct testing

.

CEC, PG&E and California IOUs encouraged DOE to continue to research room illuminance conditions that are representative of consumer homes. CEC supports improvements to ABC testing, and believes that more appropriate lighting levels can be derived from Illuminating Engineering Society of North America ( IESNA) studies. (CEC, No. 15 at p. 3) PG&E and California IOUs urged DOE to collect and analyze luminance and power data with and without ABC enabled with a range of room illuminance levels typical of consumer viewing conditions. (PG&E, No. 12 at p. 3; Cal ifornia IOUs, No. 9 at p. 3)

Although some manufactures suggested that 0 lux should be changed, m anufacturers were generally opposed to altering the room illuminance levels at which the TV is tested. Mitsubishi believes that measuring power at two levels of illuminance and assuming a linear

27 The minimum luminance to which CNET calibrates televisions for optimal vi ewing in a dark room is 137 nits. See http://reviews.cnet.com/how

- we - test/tv/ . The Imaging Science Foundation (ISF) recommends a similar minimum luminance for dark room viewing conditions. Televisi ons with an ISF Expert display mode tested by DOE operated at a minimum luminance in that mode of 100 to 130 nits. Televisions with a THX display mode tested by DOE operated a minimum luminance in that mode of 80 to 95 nits.84

relationship between the values is an approximation at best. (Mitsubishi, No. 7 at p. 5) They continued by adding that measuring at four illuminance points ( e.g. 0, 10, 100, and 200 lux) doubles the testing burden on th e lab making the measurement and does not ensure a linear relationship between any of the two points or necessarily make the power consumption approximation significantly better. (Mitsubishi, No. 7 at p. 5) NRDC stated that DOE should require testing at lo w , medium and high room light levels, all at least 100 lux or brighter, to better represent actual viewing conditions. (NRDC, No. 5 at p. 5) Further, NRDC asserted that
t he test should require the lab technician to report the power levels, at differen t lum inance levels, and leave it to the policy maker to determine the weight at each level. The test procedure should also require testing with ABC off. (NRDC, No. 5 at p. 5) CEA advised against c hanging the ENERGY STAR specification , as t esting at additional l uminance levels will not create a more repeatable and representative test method without further testing

. (CEA, No. 13 at p. 6) CEA recommends the use of ENE R GY STAR's ABC test, but chang ing "300 lux or greater" to "300 lux" with a reasonable tolerance lim it. (CEA, No. 13 at p. 6) Additionally, Panasonic noted that i f absolute luminance measurements are required at various levels other than 0 lux and greater than 300 lux , it will be difficult to develop a test method that ensures accurate and repeatable

res ults across labs. (Panasonic, No. 6 at pp.5

- 6 ) Sony believes that accurately capturing light conditions and energy savings associated with TVs equipped with ABC is difficult. Illuminance meters must be placed in the exact same position and orientation of t he light sensor of the TV, in order to properly create the desired illuminance which varies from home to home and from test lab to test lab

. Sony stated that t he lighting conditions are outside of the scope of the test procedure. (Sony, No. 8 at p. 3)85

Alte rnatively, SHARP recommended that, at a minimum, the low light condition be increased somewhat above 0 lux, but to determine an appropriate value, or if additional levels are required, more data collection and study is required. (SHARP, No. 14 at p. 5) SHA RP also supported the high illuminance condition being at precisely 300 lux, allowing for some reasonable tolerance in the measurement condition. (SHARP, No. 14 at p. 5)

To determine the appropriate illuminance levels require d during on mode testing for th ose TVs with ABC

- enabled by default, DOE analyzed a Japanese study 28 undertaken by Sony, Seikei University, Sharp, and Panasonic pertaining to room illuminance and ABC . In addition, DOE conducted its own preliminary room illuminance field test 29

. I n 201 1 , the Japanese study of 77 Japanese homes found that the most common room illuminance range of either day or night measurements was 50 to 75 lux , and room illuminance was 100 lux or less in more than 50 percent of the measurements.

In June 2011, DOE conduct ed its own preliminary field tests of room lighting levels during TV viewing events 30 . Room lighting levels and TV power consumption were logged continuously over a one - to

- two week period in nine homes. From this data, light levels were correlated to times when the TV was actually being watched. Across the nine homes, the TV was watched for 10 minutes or more 95 times in the period under consideration. DOE has collated the logged illuminance levels for each of those sessions, defined as “TV viewing session r oom

28 Matsumoto et al., "Appropri ate Luminance of LCD Television Screens under Real Viewing Conditions at Home", The SID Digest, (2011) 29 The preliminary field tests of room lighting levels can be found on the DOE website: Appliance and Commercial Equipment Standards: Television Sets . U.S . Department of Energy. August 2, 2011. < http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html > 30 Id.86

illuminance” measurements , and found that they rang ed in duration from 10 minutes to over five hours. Thirty

- one, or about one

- third, of the TV viewing sessions occurred during the day (defined as 6 am to 6 pm), and 64, or about two

- thirds, occurred at night (6 pm to 6 am). For daytime measurements, the range was 0 to 499 lux, with a mean of 116 lux and a median of 81 lux. For nighttime measurements, the range was 0 to 106 lux, with a mean of 19 lux and a median of 12 lux. Across all room illuminance measurements, the mean was 51 lux and the median was 17 lux. More than 90 percent of measurements had a room illuminance level between 1 and 200 lux, and more than 70 percent of the measurements had a room illuminance level between 5 and 100 lux.

In addit ion to the Japanese study and its own preliminary study, DOE is also aware that CLASP recently conducted a study which assessed how TV energy consumption is affected by illuminance levels 31 . The CLASP study found that there is no consistency in the way in w hich manufacturers implement ABC ( e.g. automatically adjust ing TV luminance according to the ambient light levels)

. The CLASP study suggest ed that appropriate room illuminance levels at which to measure ABC are: 10, 50, 100, and 300 lux 32 to properly charac terize how ABC performs

.
Given DOE’s preliminary results that more than 70 percent of measurements fell between a room illuminance level of 5 and 100 lux, and CLASP’s recommended room illuminance levels, DOE is proposing to require testing at 10, 50 , 100 , and 300 lux illuminance levels in this NOPR

.

luminance

- and

- power - consumption > 32 Id.87

DOE is proposing this testing in section 5.5.1 of appendix H to subpart B of 10 CFR part 430

. These proposed illuminance levels will help to characterize how TV energy consumption is altered by ABC , which is aff ected by changes in room lighting

. The CLASP study included testing on forty TVs and investigated the energy consumption of TVs using ABC at various illuminance levels. DOE’s own laboratory testing revealed that television s implement ABC differently, with screen luminance often following a complex function of room illuminance. Some televisions exhibit an increase to nearly full screen luminance slightly above 0 lux, while others exhibit an “S

- shaped” response to room illuminance, with maximum change occurri ng between approximately 50 and 100

- 150 lux. H aving at least three (and ideally four) measurement points at increasing room illuminance levels can begin to capture the shapes of either of these behaviors that become clearly evident with larger numbers of m easurements
.
DOE is not proposing testing at 0 lux, because it believes that ambient lighting levels this low are very difficult to achieve in practice in homes or laboratories when the television is operating

. DOE is only proposing one point above 100 lux , based on the limited evidence available from the Japanese study and its own study ( both reference d above), DOE assumes that viewing at illuminance levels higher than 100 lux will be limited. The studies measured room illuminance at different points

– the Japanese study from the top of the television and facing the viewer, the DOE study from the bottom bezel of the television and facing the viewer

- however, with the limited data collected, static measurements of light levels at these locations in the DOE study suggest that the difference in the recorded values is relatively small (12 percent lower when measured at the top of the television). DOE is also proposing to measure these 4 illuminace values with the IEC 62087

- 2011 main menu displayed on the TV. Th is screen is a static image that is seen directly before the Dynamic Broadcast video clip and is a predominantly black88

screen. This allows the TV to stay on so it doesn’t need to be warmed up again and increases repeatability.

DOE is proposing testing at multiple levels to reflect how ABC could change display luminance in relation to changes in room illuminance . Although DOE believes that testing at four illuminance levels is the most appropriate for this test procedure, it is also considering measuring at alternative illuminance levels to reduce test burden. DOE welcomes any comment on potentially testing less than four room illuminance levels, including which levels would be recommended and the rationale for such levels

.

DOE believes that it is difficult to measure exact ambient light values with illuminance meters having high accuracy (high resolution). As such, DOE is proposing specified tolerance values for each ambient light level. All measurements made shall be within the specified tolerance levels. T he proposed t olerance levels for room illuminance measurement s are based on the observation that power consumed by ABC

- enabled products varies greatly with changes in ambient lighting conditions less than 100 lux. Based on this observation, DOE would requi re that measurements at lower lighting levels be made as accurate as possible and , as such , proposes low tolerance levels at 10 lux ( ± 1 lux ) and 50 lux ( ± 2 lux ). DOE observed low variance in power consumed by TVs at higher ambient light levels and hence proposes greater tolerance levels at 100 lux ( ± 5 lux) and 300 lux (± 9 lux). These tolerance requirements have been incorporated in section 5.5.1 of appendix H to subpart B of 10 CFR part 430 DOE seeks comments from interested parties on setting to lerance levels at each room illuminance point. ( See Issue 8 in section V.E ”Issues On Which DOE Seeks Comment” )89

DOE is currently not proposing to weigh power consum ption at each of the illuminance levels. DOE is , however, considering a weighted averag e to calculate the overall power consumption recorded when testing at the four illumination levels by assigning equal weights to each of the values

. The weighting would reflect the amount of time that the average TV spends in that particular illuminance level. Providing weighting to different illuminance levels reflects the fact that TVs are watched in rooms with different lighting levels and at different times of the day

. If DOE had additional data on the proportion of time TVs spend within different illuminance ranges, DOE might consider assigning different weightings to the power consumptions recorded at each illuminance level. D OE welcomes comments from interested part ies on the methods under consideration. (See Issue 8 in section V.E ”Issues On Which DOE Seeks Comment”)

.

ii. Method for Creating Illuminance Conditions
Once the respective illuminance levels have been selected, DOE must specify how to create the room illuminanc e in the test procedure to be both repeatable and representative. This involves the orientation of the illuminance measurement meter, the light source type and the location for measurement.

In today’s NOPR, DOE is proposing to measure the room illuminance at the location of the ABC sensor on the TV with the light entering directly into the sensor. This method is currently being employed by ENERGY STAR v. 5.3 as well as IEC 62087

- 20 11 , and was generally supported by interested parties. However, DOE is also c onsidering an alternative method. The alternative method requires that the room illuminance be created using a diffused90

light source, and be measured either at the center of the screen or the location of the ABC sensor. In response to the 2010 RFI, DOE rec eived comments on the appropriate method for creating illuminance levels.

DOE received general comments requesting a test procedure that clearly outlines where to create and measure room illuminance with respect to the TV. NRDC encourages DOE to establish a more specific test method on how to measure the light that is entering the ABC sensor and/or the TV screen, but NRDC did not specify an appropriate alternative. (NRDC, No. 5 at p. 5) NRDC stated that the test procedure should provide detail on the orien tation of the illuminance meter, the type of light source , and the location for measurement. (NRDC, No. 5 at p. 6) PG&E and California IOUs recommend ed that DOE specify guidance on illuminance meter orientation, source light and the direction of the source light to ensure consistent testing across products. (PG&E, No.12 at p. 3; California IOUs, No. 9 at p. 3)

Commenters expressed desire for measuring the room illuminance at the location of the light presence sensor with the light directly entering the sens or . PG&E and the California IOUs recommend that measurement of room illuminance be taken at the location of the TV light presence sensor. (PG&E, No.12 at p. 3; California IOUs, No. 9 at p. 3) Sony believ ed that to accurately capture light conditions, the i lluminance meter should be placed at the sensor. (Sony, No. 8 at p. 3) Panasonic recommend ed that ABC be measured with the light entering directly into the TV's ambient light sensor as specified by IEC 62087

- 2008, ENERGY STAR v. 4

. 1 , and CEA 2037

. (Panasonic, No. 6 at p. 6) CEA similarly commented that the illuminance measurement should be taken at the sensor and the illuminance meter should be in the same horizontal orientation as the light sensor to ensure repeatability across measurements. (CEA, No.91

13 at p. 6) Finally, Panasonic commented that the illuminance should be measured immediately adjacent and in the same plane as the TV's ambient light sensor opening

. They believe that measuring light at the center of the screen will not provide meaning ful and repeatable results. (Panasonic, No. 6 at p. 6) SHARP commented that manufacturers do not gain any advantage by putting the ABC sensor in an obscure or hidden position, and thus the illuminance measurement location should be at the sensor. (SHARP, N o. 14 at p. 6) SHARP also believe d that no problem exists with respect to measurement location and lighting, and anything other than the IEC 62087

- 2008 method adds complexity, uncertainty and cost to the measurement. (SHARP, No. 14 at p. 6)

DOE evaluated a second option for furnishing ambient light to the automatic brightness control sensors in a laboratory setup. This second option utilizes a diffuse light source. Such a source would be located further away from the TV than a direct source, and its light would reach the TV through a combination of direct and indirect (e.g., reflections from the ceiling, walls, and floor) pathways. Although a diffuse light source better represents actual in

- home lighting conditions, DOE determined that such an approach depe nds on too many variables that are difficult to control and which introduce uncertainties into the test procedure relative to the direct approach. The diffuse light source would need to be much brighter in order to yield the target lux values at the televi sion. The light would be arriving at the television from many different angles and would be incident on the television screen as well as its ABC sensor. This increases the likelihood that the technician’s position in the room during the test would influenc e the measured result, and makes it difficult to employ a non

- contact luminance meter for television screen brightness measurements. Finally, differences in test room size, configuration, surface reflectivity, and light source type would also make it very difficult to replicate identical test92

conditions in multiple laboratories. For the above reasons, DOE proposes to employ only a direct light source for all ABC testing.

In addition to specifying to lighting position and sensor measurement location, DOE also believes that it is necessary to specify the lighting type. Of artificial lighting sources , incandescent light most closely follows the spectral distribution of natural light. Compact fluorescent lights (CFL) and LED tend to be discontinuous in the sp ectral density curves which may impact the ABC sensors ability to perceive light. Incandescent lights have a color rendering index (CRI) of about 100 while CFL and LED have a CRI ranging from 75

- 85 (natural light has a CRI of 100, a metric used for how lig ht makes the perceived color of an object appear). DOE is
p roposing that the room illuminance be created only by using 100 watt halogen incandescent light bulbs, although the number of bulbs need is dependent on the size of the room and the distance from t he ABC sensor.

While DOE feels that specifying a halogen incandescent is sufficient for creating a repeatable lighting condition, DOE requests comments on incorporating a color temperature range in addition to lighting type. Consumers have a wide variety of lighting options to choose from ranging from “warm” (2800

– 3000 K) to “cool” (3600

– 5500 K) color temperatures and it is still unknown how these characteristics may be perceived by ABC sensors. DOE also requests
comments on a warm

- up time for the ligh ting source. Incandescent lights do not typically have the same warm

- up characteristics as other lights like CFL that require time before reaching their optimal brightness.93

In today’s NOPR, DOE is proposing to measure the room illuminance at the location o f the ABC sensor on the TV with a halogen incandescent light source entering directly into the

sensor in section 5.5.2 of appendix H to subpart B of 10 CFR part 430

. Although neither ENERGY STAR v. 5.3 or IEC 62087

- 2011 specifies the particular location of the light source, DOE believes that through specifying the location , it will have a more thorough and complete test procedure that is representative of actual use. Although DOE is proposing to measur e using only one light source, DOE is also interested in receiving feed back on measuring using multiple light source s .

Television Sets Shipped without Aut omatic Brightness Control Enabled For TVs shipped without ABC enabled, DOE is proposing to incorporate testing consistent to that in the ENERGY STAR v. 5.3 , which references Section 11: Measuring Conditions for Television Sets in On (average) Mode of IEC 6 2087, Ed 2.0

. DOE believes that this is a respected method that is widely accepted in industry and reasonably measures the average on mode power consumption of the TV in section 5.4.1 of appendix H to subpart B of 10 CFR part 430

. In this test procedure, t he on mode power consumption is obtained by playing the IEC 62087

- 20 11 dynamic

- broadcast video signal (which was created to mimic typical TV content) in “as shipped” condition which is the mode in which DOE assumes that most TVs stay according to feedback from Sony. As noted a bove, Sony commented that their call center data indicates that more than 95 percent of returned sets remain in the home picture setting when received

. ( Sony, No. 8 at p. 2 ) DOE did not receive any comments pertaining to on mode power testing for TVs shipped without ABC enabled.94

d. Three Dimensional Display Testing In the 2010 RFI, DOE requested comment on incorporating a test method for testing TVs capable of displaying 3D images in 3D mode . 75 FR 54 048, 54051. Interested parties commented on the inclusion of this testing into the DOE test procedure

.
All agreed that 3D was likely to become increasingly prevalent. Interested parties, however, had mixed views as to the importance of DOE incorporating 3D testing in this version of its test procedure. Some did not seem to consider it a priority, some considered it premature, stating that the market share is currently small but rapidly increasing and the technology is still developing, and others felt it sh ould clearly be included. Sony offered its support to DOE’s studies into 3D technology. They believe that the amount of time consumers spend watching 3D content is currently relatively small compared to 2D content but increasing. Sony believes that suffici ent time should be allowed for the IEC to create a 3D version of its 2D dynamic broadcast

content video signal. (Sony, No. 8 at p. 3) Mitsubishi commented that a test procedure for 3D should be included in DOE’s test procedure but it need not involve a 3D disc, 2D content could be converted to 3D in real time

. (Mitsubishi, No. 7 at p. 6) NRDC commented that TVs having the "3D boost" feature could result in a significant increase in TV power to display 3D content. (NRDC, No. 5 at p. 6) Panasonic asserts that TVs display 3D images in a similar manner as 2D images. Thus, they believe that a TV that is efficient in 2D mode will also be efficient in 3D mode, when compared to other TVs operating in 3D mode

. Once IEC ha s developed a 3D clip, or even before, Panason ic believ es that it should be reference d by DOE

. (Panasonic, No. 6 at p. 7) CEA believes that DOE should support standards development organizations investigating 3D technologies but due to the lack of a standardized method and current small volumes on the market, 3D technology should not be included in DOE's current test procedure. CEA95

acknowledged that it may be appropriate to modify the DOE test procedure in the future to include 3D testing. (CEA, No. 13 at pp. 7

– 8) P.R. China suggested that it is too early to consider 3D technology in the DOE test procedure. ( P.R. China, No. 16 at p. 5) SHARP believes that it is premature to set power standards for TV in 3D modes stating that there are three things that are needed: standardized language for testing, a standardized test signal , and accurate weightings based on actual viewing habits. SHARP recommended that the IEC develop a 3D dynamic broadcast

- content video signal, but such a result is unlikely to be available before late 2012. ( SHARP, No. 14 at p. 7) DO E should revisit 3D power measurements when a 3D dynamic broadcast

- content video signal becomes available

– probably no earlier than 2013. (SHARP, No. 14 at p. 7) PG&E , California IOUs , and Mitsubishi supported DOE in currently including 3D testing in its proposed test procedure. PG&E and California IOUs commented that 3D TVs are expected to significantly increase in market share, and drop in price. Therefore they urged DOE to develop a test procedure that appl ies to 3D TVs on the market. (California IOUs, No. 9 at p. 3; PG&E, No. 12 at p. 3) Although Mitsubishi recognized the difficulties of creating a test procedure for testing 3D, they believed that power consumption in 3D operating mo de(s) should have a single, recognized test procedure, and that power consumption in 3D operating mode(s) should be measured. (Mitsubishi, No. 7 at p. 6)

DOE recognizes that 3D content is becoming increasingly popular and that 3D TVs are becoming more aff

ordable. PG&E and California IOUs cited a study that showed that 3D TVs are projected to increase from 4.2 million units in 2010 to 78 million units by 2015, rising at a compound annual growth rate of 80 percent, and that the global average selling price f or 3D TVs96

in 2015 will drop by more than half the price in 2010 33 . (California IOUs, No. 9 at p. 3; PG&E, No. 12 at p. 3) Industry has more recently indicated that over the next couple of years 3D will become a common feature on many TVs, almost available a s standard on larger screen sizes and with higher end models (Society for Information Display conference, 2011). Moreover, 3D content is becoming increasingly prevalent with emerging native 3D material (movies, sports content etc. shot in 3D) , and Blu

- ray players and TVs on the market with the ab ility to convert content from 2D to 3D. DOE understands the need for a standardized method for measuring the power consumption of TVs in 3D mode

. DOE’s research thus far indicates that for most mainstream technologi es’ 3D mode consumes a significant additional power premium. However , DOE understands that 3D is a developing technology and will most likely take time to mature

.
In today’s NOPR , DOE is not proposing to include a test procedure to measure 3D
energy consu mption for the reasons that : (a) 3D technology has not yet stabilized, and (b) a uniform method for 3D mode energy measurement has not yet been created

. However, DOE is considering two potential alternatives for future inclusion in its test procedure. The two alternatives involve either creating a 3D dynamic broadcast

- content video signal similar to that of the IEC 62087

- 20 11 dynamic broadcast

- content video signal , or employing a device that can uniformly convert the 2D dynamic broadcast

- content video signal to 3D and output 3D content in real time. The two potential test methods under consideration are outlined below

.
For the first approach that DOE is considering, DOE would create a 3D test disc capable of being played in a Blu

- ray player. DOE has be en working closely with the IEC. IEC has agreed

33 Global 3

- D TV Shipments Set to Soar to 78 Million Units in 2015. Riddhi Patel. iSuppli Press Release. March 1, 2010.97

in principle to provide DOE with all the rights which it is able to provide DOE to modify the 2D test clip and distribute modified versions of the test clip

. If DOE creates a modified 3D version of the IEC te st clip for any purpose, it has agreed to provide a copy to IEC which IEC could then use in its development of an IEC 3D test clip 34

.
It is the intent of DOE that the disc will be capable of playing Blu

- ray format 3D , a HDMI 1.4 interface at 1080 horizontal lines of vertical resolution and at least 1440 vertical lines of horizontal resolution. When playing the disc, 3D capable TVs will recognize that the disc contains 3D content, and will switch into 3D mode. The average APL of the 3D disc would be 34
percen t thus simulating normal viewing content even while the TV is in 3D mode. At this time, DOE believes that this approach is the best approach for developing a 3D test procedure and is interested in working with the IEC and other interested parties in its de velopment.

DOE is also considering a second approach , which employ s a device that can convert the 2D test clip to 3D and output 3D content in real time . Under this approach, DOE would try to develop a performance specification for Blu

- ray devices that hav e this capability to ensure that the test results are consistent across labs if using different 2D to 3D convertors. DOE has tested some of these devices, and cannot conclude at this time what the performance specification should be for these devices. Howe ver, DOE welcomes comments on this aspect of the test procedure under consideration.

34 IEC and necessary copyright holders have agreed in principle to allow DOE to modify the test clip and return it to IEC. IEC is able to assign rights over the material in the test clip with the possible exception of certain portions of the test clip owned by one copyright holder. Currently, DOE is in discussions with that copyright holder.98

As mentioned, DOE has performed 3D testing using two Blu

- ray players available for sale in the U

. S

. from different manufacturers, both of which are able to convert 2D ima ges to 3D in real time. DOE measured the average power consumption over a specified amount of time and then play ed a 2D disc of the same footage on the 2D to 3D converter . DOE found very little difference between TV power measured using 3D source material and TV power measured using 2D source material converted to 3D using the Blu

- ray players. To make the comparison, DOE used market available Blu

- ray videos with both a 3D and a 2D version and measured the energy

consu mption over the same ten minute section of the film using both methods for generating 3D material. The comparison was made on five 3D capable televisions spanning LED LCD, plasma, and DLP technologies.

DOE believes that , generally, the limited test result s of the convertor are comparable to those of playing 3D content. However, there were issues with this approach. DOE is concerned that the variability found between playing the test clip in the converter , vers us playing a 3D test clip, can be a function of the test clip, converter and TV used in the test and is not certain how to develop a n adequate performance specification for the converter alone

. DOE also found through testing that not all convertors worked with all TV brands. Further, DOE determined tha t , in some

cases , the convertors put the TV into a mode that consumed less energy when playing 2D content converted to 3D than when playing the same content in 2D.

DOE requests comment on these two options for generating the video signal for 3D TVs , along with any other considerations for testing 3D TVs. (See Issue 10 in section V.E ”Issues On Which DOE Seeks Comment”)

5. Standby and Off Modes
As mentioned above, EISA 2007 requires DOE to include consideration of standby mode and off mode energy consumption in future amendments to both its test procedure and energy conservation standard. In order to adhere to EISA 2007, DOE is proposing to inclu de the standby mode requirements according to IEC 62087

- 2011 and the off mode requirements according to IEC 62301

- 2011

. When developing a proposed standby and off mode test procedure, DOE assessed both IEC 62301

- 2005 Household Electrical Appliances

– Measu rement of Standby Power and IEC 62087

- 2011

. ENERGY STAR v. 5.3 references IEC 62087

- 2011

. In today’s NOPR, DOE is proposing to incorporate standby tests for standby

- passive in section 5.6.1 (standby

- passive mode test) of appendix H to subpart B of 10 CFR p art 430 and standby

- active, high in section 5.6.2 (standby

- active, high mode test) of appendix H to subpart B of 10 CFR part 430 as well as an off mode test in section 5.7 (off mode) of appendix H to subpart B of 10 CFR part 430

. Although DOE is not curren tly proposing to include a standby test for standby

- active, low , DOE is considering this requirement for the future

.

In the 2010 RFI, DOE requested comments dealing with standby and off mode. Specifically DOE focused on additional f unctions, internet conne ctivity and power saving technologies, since they can possibly alter the energy consumed by the TV . 75 FR 54048, 54051.

a. Additional Functions As mentioned above, additional functions have the potential to increase energy consumption while the TV is in standby and off mode. Additional functions are defined as any function that is not required for the basic operation of the device. Although DOE di d not100

specifically request comments pertaining to additional functions in the 2010 RFI, both NRDC and SHARP provided comments on assessing the power use associated with additional functions.

NRDC asked that DOE provide guidance in its test procedure for ad ditional function s and that DOE revise the standby section of IEC 62087

- 2008 , which is the same as IEC 62087

- 2011

. NRDC believes that the test procedure must address whether the TVs additional functions should be left as is, turned on , or turned off/ disabled prior to testing. (NRDC, No. 5 at p. 2)

Although NRDC requested guidance, they were generally opposed to testing with additional functions switched on unless initially enabled by default. NRDC believes that built

- in DVD and Blu

- ray players should be tested without a disc inserted , and play should not be selected

. H owever, they believe that the DVD and Blu

- ray players should not be allowed to be turned off or physically removed prior to testing. (NRDC, No. 5 at p. 2) NRDC also commented that the TV should be tested without the cable card inserted, but DOE should potentially include a supplement to its test procedure that allows guidance on how to report for features such as cable cards. (NRDC, No. 5 at p. 3) Additionally, DOE should gather data and e valuate methods, including the Australian method, which includes measuring standby

- active and standby

- passive once the TV has been tuned to an Australian broadcast channel. (NRDC, No. 5 at p. 7)

SHARP was also opposed to enabling additional functions when conducting energy measurements. SHARP commented that IEC 62087

- 2008 requires that additional functions be turned off to provide for equivalent TV model comparison. (SHARP, No. 14 at p. 8) SHARP recommends that DOE follow precedence and measure the basic TV functions without101

intervention in the areas of nascent technologies, services and innovations. (SHARP, No. 14 at p. 9)

I n this NOPR, DOE is proposing testing the TV as shipped, without manually enabling
any additional functions

. This method is consistent with the comments made by both SHARP and NRDC

. Although e nabling additional functions while testing in standby and off mode w ould encourage manufacturers to lower energy consumption for those functions , it w ould make it difficult to compare TVs with differ ent functions

. Also, DOE is not aware of any usage data that illustrates how consumers use TVs with additional functions and DOE believes that proposing testing with additional functions would require an understanding of such usage .

b. Power Saving Technologies The number of TVs that are being sold with various power saving technologies is continuing to increase, and therefore DOE investigated the how these technologies affect energy consumption

. These technologies include, but are not limited to, auto

- s hut

- off , presence sensor, DPMS , and HDMI

- CEC.

Panasonic, Sony, NRDC , and SHARP believe that TVs with power saving technologies should not be given an energy credit in the current rulemaking because many are still being developed. Panasonic believes that it would be difficult to determine the amount of power saved and to obtain data by various power saving technologies and complex measurement procedures will not be useful. (Panasonic, No. 6 at p. 7 ) Sony stated that it is impossible to know the actual savings of energy saving functions, so additional studies are needed prior to DOE adopting them in its test procedure. (Sony, No. 8 at p. 4) LG stated that the ENERGY STAR and IEC 62087

-102

2008 test procedu re, which only account for ABC, adequately evaluate power saving functions available today. (LG, No. 3 at p. 2) CEA also stated that not every possible energy using feature needs to be covered, especially if it is too difficult, impractical, costly or spec ulative

. (CEA, No. 13 at p. 2) More specifically, NRDC and Panasonic do not support giving credit for presence

sensors ; a power saving technology that turns the TV off if it senses that no consumers are viewing it. They believe that the technology will lik ely be disabled by the consumer ; assuming the TV is shipped with presence sensors enabled. (NRDC, No. 5 at p. 7; Panasonic, No. 6 at p. 8).

SHARP also noted that many power saving technologies are proprietary and should therefore be avoided. Specifically, DPMS has intellectual property implications. (SHARP, No. 14 at p. 9) SHARP believes that HDMI

- CEC can provide some mechanisms for power saving. They supported their comment by stating that the application layer is not well enough defined for consistent cr oss - company interoperability, and many HDMI

- CEC implementations are currently proprietary. (SHARP, No. 14 at p. 9)

Many interested parties supported DOE research into power saving technologies. NRDC urged DOE to revisit power savings features , and whether credits should be provided for power saving features. (NRDC, No. 5 at p. 7) CEA also encouraged DOE to continue to study and investigate energy saving features but be cautious as to not promote technology that is restrictive and costly. (CEA, No. 13 at p. 8) CERC believes that the standard should be allowed to evolve with new technologies. CERC commented that technologies still in early development , including automatic shut

- off and ABC , should be allowed to be developed more fully before a standard and test procedure are imposed on their operation, allowing manufacturers more incentive to103

innovate. (CERC, No. 10 at pp. 2

- 3) PG&E and the California IOUs urged DOE to account for new technologies in the test procedure to the greatest extent pos sible. (PG&E, No. 12 at p. 4; California IOUs, No. 9 at p. 4)

Finally, some manufacturers commented on specific power saving technologies available in products today. Sony commented that its TVs contain intelligent presence sensors with face and motion de tectors, light sensors, power savings (regardless of picture mode), idle TV standby, auto shut

- off and the energy savings switch (completely off). (Sony, No. 8 at p. 4) LG commented that their TV s have features that place the TV into standby mode if no sig nal is present for 15 minutes. (LG, No. 3 at p. 2) SHARP commented that the auto

- standby feature that is available in some manufacturers’ products can potentially save energy , but also may annoy consumers. (SHARP, No. 14 at p. 9) SHARP also believes that C alifornia’s requirement that the power button put the TV into passive standby, can have negative consequences, such as terminating a nearly complete program guide download. (SHARP, No. 14 at p. 9)

Given the interested party feedback, DOE is not proposing t o test new power saving technologies because DOE believes more investigation is needed to be able to better understand any potential benefits from these technologies. Although DOE will continue to investigate the new technologies, DOE believes that the mar ket is currently at too early a stage of development. In order to continue to investigate these new technologies, DOE welcomes interest parties submit information pertaining to all power saving technologies, which would help DOE in its investigation presen t on TVs.104

c. Standby Modes i. Standby

- Passive Mode As stated in section 5 above, DOE is proposing a test procedure for standby

- passive mode in section 5.6.1 ( s tandby

- pas sive m ode t est) of appendix H to subpart B of 10 CFR part 430 . IEC 62087

- 2011 defines standby

- passive mode as the mode in which t he appliance is connected to a power source, produces neither sound nor picture but can be switched into another mode with the remote control unit or an internal signal as referenced in III.C.3.a of this NOPR

. Testing in this mode would require putting the TV into standby

- passive mode as de fined in section 2.12 (s tandby

- passive mode) of appendix H in subpart B of 10 CFR part 430 , and measuring the power consumed according t o section 4.3.1 of IEC 6230 1

- 201 1

. Standby

- passive mode would include modes such as when the TV is connected to the internet but not actively receiving a signal.

ii. Standby

- Active, Low Mode The number of TVs that are being sold with the capability of accessing the internet (either wirelessly or via Ethernet ) is continuing to increase; PG&E and California IOUs stated that by 2014, internet

- enabled TVs are estimated to account for 54 percent of the total global TV market. They supported their statement by commenting that in 2010, ship ments of these TVs rose 125 percent globally from 2009. (PG&E, No. 12 at p. 4; California IOUs, No. 9 at p. 4 ) In the 2010 RFI, DOE requested comments on testing TVs with internet connectivity. 75 FR 54048, 54051.

Some interested parties commented in favor of TVs being connected to the internet when measuring standby and off mode energy consumption. NRDC suggested that the TV should be10 5

connected to the internet, then turned off normally, and the energy consumption associated with the TV being connected to t he internet should be measured and reported as part of standby power use. (NRDC, No. 5 at p. 2) PG&E and the California IOUs also stated that DOE should incorporate internet connectivity and power usage associated with this feature in the test procedure. T hey suggested that DOE do this by including a network mode, consistent with what will be included in IEC 62301 Edition 2.0. (PG&E, No. 12 at p. 4; California IOUs, No. 9 at p. 4)

Other interested parties commented that internet connectivity energy consumpt ion should not be included in the test procedure . Interested parties commented against including a general internet measurement as well as enabling internet when conducting the standby test. Interested parties reasoned that internet connectivity has not be en researched thoroughly , and is still in the early development stages. Sony commented that their limited data suggests that the power consumption of TVs equipped with Ethernet ports is equivalent to the power consumption in the home mode while streaming c ontracted network connects from the various service providers. (Sony, No. 8 at p. 3) Sony also stated that because power and usage of internet capable TVs is unknown, additional study is needed prior to incorporating it into the test procedure. (Sony, No. 8 at p. 3) CEA similarly stated that internet connectivity is still in an early phase of development and should therefore not be included in the test procedure without further research. (CEA, No. 13 at p. 8) Panasonic recommends using the same on mode powe r measurement with the IEC 62087

- 2008 dynamic

- broadcast video signal, regardless of the TV’s internet capabilities. (Panasonic, No. 6 at p. 8) Panasonic believes that the power consumed from an internet connection is minimal and complex, and will be diffic ult to reproduce. (Panasonic, No. 6 at p. 8) SHARP further commented that consumers all use the internet differently, so setting a test procedure to mirror actual internet use would be a daunting task with minimal value. ( SHARP ,106

No. 14 at p. 8) SHARP belie ves that much more study is required before DOE can characterize the power consumed from TVs based on active internet use. ( SHARP , No. 14 at p. 8) SHARP believes that due to competitive pricing, TV s have limited storage capacity, and therefore internet com munications are limited or non

- existent when the TV is in sleep mode, making testing it not relevant. ( SHARP , No. 14 at p. 8)

Other interested parties commented on specific details pertaining to internet connectivity energy consumption. NRDC believes that t he test procedure should have language to ensure that no content is being downloaded from the internet while the measurement is being made. (NRDC, No. 5 at pp. 2

-- 3) LG commented that “currently the HDMI input is available to the IEC Standard 62087 internet source; however it is impossible to implement it through the current environment LAN Port.” (LG, No. 3 at p. 2) DOE notes that while IEC 62087

- 2011 provides a video signal of different websites to represent internet energy consumption, there is c urrently no standard method for measuring actual internet usage when connected to the internet via a LAN Port.

Given the comments received in the 2010 RFI, DOE researched the energy consumption associated with internet, HDMI , and cable connectivity. DOE c ompleted standby and off mode energy testing while the TV was connected to the internet (both wirelessly and via Ethernet) , while connected to a cable signal, while connected to a peripheral device through a HDMI cable and while not connected to input or o utput source s except for power

. DOE found very little107

evidence of increased energy consumption associated with additional connections while the TV was in s tandby and o ff mode 35

.
In today’s NOPR, DOE is proposing to test s tandby and o ff mode energy consumpti on without having th e TV connected to the internet in sections 5.6 (standby mode tests) and 5.7 (off mode test) of appendix H to subpart B of 10 CFR part 430

. As mentioned above, DOE also conducted testing when the TV was connected to both a cable signal and an HDMI input

. DOE did not measure a significant power increase when the TV was connected to the internet, cable or an HDMI input while in standby mode or off mode 36 DOE believes that conducting additional standby testing while the TV is connected to a n internet, cable or HDMI input is unduly burdensome due to the lack of significant results indicating increased energy consumption from DOE’s testing

. T herefore , DOE is not proposing to require that the TV be connected to a cable input , HDMI input or to the internet when testing s tandby and o ff mode energy consumption. However, DO E welcomes comments by interested part ies on the energy consumption associated with internet connectivity in standby mode should be included

. (See Issue 11 in section V.E ”Issues On Which DOE Seeks Comment”)

.

iii. Standby

- Active, High Mode IEC defines s tandby

- active, high as the mode when the appliance is connected to a power
source, produces neither sound nor picture but can be switched into another mode with the remote control unit or an internal signal and can additionally be switched into another mode with

35 The data indicating a lack of increased power co nsumption associated with connecting the TV to the internet, cable or an HDMI input can be found on the DOE website: Appliance and Commercial Equipment Standards: Television Sets . U.S. Department of Energy. August 2, 2011. < http://www1.eere.energy.gov/buildings/appliance_standards/residential/tv_sets.html > 36 Id.108

an external signal and is exchanging/receiving data with/from an external s ource. DOE believes that the TV is in standby

- active, high mode when the TV is actively exchanging/receiving data (likely from the internet) as well as while in DAM mode. In the 2010 RFI, DOE requested feedback as to the possib i l it y of including a DAM test . 75 FR 54048, 54051

.

iv. Download Acquisition Mode

ENERGY STAR v. 5.3 defines DAM as the mode where the product is connected to a mains power source, is not producing a sound or a picture, and is actively downloading data, to include but not limited to, chan nel listing information according to a defined schedule for use by the electronic programming guide, TV setup data, channel map updates, TV firmware updates, monitoring for emergency messaging/communications and/or otherwise communicating through a network protocol. DOE believes i t is important to include DAM testing because the tested TVs ha d heightened energy consumption while in this mode.

S everal interested parties commented that DAM should be tested . PG& E and the California IOUs indicated that there has been at least one reported instance of a TV consuming a significantly greater amount of power and spending a majority of time in DAM when the TV should have been in standby mode. Therefore, they urged DOE to account for DAM in its test procedure. (PG&E, No.12 at p. 5; California IOUs, No. 9 at p. 5) They requested that the test programming content, used for testing in DAM, should be publically available and able to be utilized by non

- proprietary technology. (PG&E, No.12 at p. 4 ; California IOUs, No. 9 at p. 4 )109

Many interested parties specifically suggested that DOE implement the “CEA Test Procedure for Download Acquisition Mode Testing 37 ” (CEA test procedure for DAM testing). Specifically, Sony , LG, Panasoni c and CEA recommended that DOE adopt this test procedure. (Sony, No. 8 at p. 3; LG, No. 3 at p. 2; Panasonic, No. 6 at p. 8 ; CEA, No. 13 at p. 8) Panasonic and Sony supported their recommendations by noting that ENERGY STAR v. 4.1 reference s the CEA test p rocedure for DAM testing. (Panasonic, No. 6 at p. 8; CEA, No. 13 at p. 8)

Alternatively, SHARP commented that although the CEA test procedure for DAM testing is a good test procedure, it should not be incorporated into DOE’s test procedure. SHARP supports the flexibility of the CEA test procedure for DAM testing, but is concerned that it is not specific enough to be used by third parties. However, SHARP is not aware of any test procedure that is specific enough to fit these criteria. ( SHARP , No. 14 at pp. 8 , 10)

In the 2010 RFI, DOE noted that ENERGY STAR v. 4.1 tests DAM according to the Rovi DAM test procedure. However, Rovi commented that DOE should not incorporate the Rovi DAM test procedure into the DOE test procedure. (Rovi, No. 4 at p. 2) Rovi explained that EPG software maintains a local database of programming available to the viewer, which is periodically downloaded during times when the TV is in the standby or off mode. Rovi noted that the location, previous downloads, data delivery method and communication errors are among the things that affected power consumption, meaning if any of these conditions are varied, different results will be obtained. (Rovi, No. 4 at p. 1) Rovi stated that in the near

- future a revision to ENERGY STAR v. 4.1 will replace the Rovi test procedure with a generic system

37 CEA Procedure for D ownload A cquisition Mode DAM Testing: For TVs, September 8, 2010 < http://www.energystar.gov/ia/partners/prod_development/revisions/downloads/television/CEA_DAM_Test_Proce dure.pdf >110

that depends in large measure on specific technical knowledge of the device under test (after the publication of the 2010 RFI, ENERGY STAR has revised their test procedure and standard to include the CEA test procedure for DAM testing ) . (Rovi, No. 4 at p. 1)

DOE notes that the CEA test procedure for DAM testing does not identify specific connections to be used when conducting testing. CEA only states that an appropriate signal source for communication should be used but does not specify what connection should be utilized when more than one connection could be used to communication with the DAM function. DOE believes that a hierarchy of network connection types is needed when more than one connection is capable of communicating with the DAM function to produce a more repeatable test procedure. DOE is proposing the foll owing priority to ensure consistency across standby

- active, high mode tests in section 5.6.2.1 of appendix H to subpart B of 10 CFR part 430 :

1) Wi

- Fi 2) Ethernet. If the UUT supports an Energy Efficient Ethernet, then it shall be tested using that connect ion

. 3) Thunderbolt 4) USB 5) Firewire 6) Other
In today’s NOPR, DOE is proposing to include the DAM energy consumption testing under its s tandby

- active, high test method as defined in 2.3 ( d ownload acquisition mode) of111

appendix H to subpart B of 10 CFR part 430

. The majority of interested parties including CEA, Sony, LG, Panasonic, PG&E, California IOUs and NRDC were all in fa vor of requiring a DAM energy consumption test. Many, including CEA, Sony, LG and Panasonic, recommended incorporating the CEA test procedure for DAM testing . Given the positive input from interested parties supporting a DAM test , and particularly the CEA test procedure for DAM testing , DOE is proposing to incorporate by reference the CEA Procedure for DAM Testing in section 5.6.2 (standby

- active, high mode test) of appendix H to subpart B of 10 CFR part 430

. DOE is also aware that TVs can communicate and o btain similar information via an internet connection. Although DOE has developed a network connection priority list of preferred connections to conduct DAM testing, DOE seeks comment on using a priority list and the hierarchy that should be used

. DOE also seeks comments from interested parties on the method for measuring standby mode energy consumption in all standby modes

. (See Issue 12 in section V.E ”Issues On Which DOE Seeks Comment”)

.

d. Off Mode DOE is proposing to test TVs in the off mode if applicable

. DOE is defining off mode according to the IEC 62087

- 20 11 definition

. Off mode is the mode w here the appliance is connected to a power source , produces neither sound nor picture , and cannot be switched into
any other mode with the remote control unit, an external , or internal signal

. This mode will not pertain to TVs that are only able to be switched on or off with a remote, rather it will be applicable to TVs th at have an additional switch or method of reaching this mode. In today’s NOPR, DOE is proposing that the power consumed in off mode be tested according to IEC 62301

- 201 1 section 3.5 in section 5.7 (off mode test) of appendix H to subpart B of 10 CFR part 430

. EISA 2007 requires DOE to implement an off mode energy consumption measurement. (42112

U.S.C. 6295(gg)(2)(A)) T his particular off mode test will meet the EISA 2007 requirements and allow DOE to capture the energy consumption associated with the TV while it is turned off. DOE seeks comments from interested parties on the method for measuring off mode energy consumption

. (See Issue 12 in section V.E ”Issues On Which DOE Seeks Comment ”)

.

6. Energy Efficiency Metric(s) for Televisions In today’s NOPR, DOE is considering two methods for determining the metrics of TVs in order to receive stakeholder comments

. These methods include a luminance ratio , on mode energy consumptio n, standby mode energy consumption, and off mode energy consumption.

The first method would output four separate metrics, including a luminance ratio, on mode energy consumption, standby mode energy consumption, and off mode energy consumption. T he test p rocedure yields a ratio of the home picture setting luminance to the retail picture setting luminance. This number would be expressed as a percent age (i.e., the luminance ratio)

. The test procedure would also output an o n mode energy consumption according to the on mode test for TVs with ABC enabled by default or the on mode test for TVs without ABC enabled by default. F or the standby mode tests, all TVs should be tested according to the standby

- passive mode test

. For TVs with DAM, the test proce dure would also propose requiring an average energy consumption reading for standby

- active, high mode. Finally, the test procedure would record the off mode energy consumption.

Alternatively, DOE is also considering a single output metric based on combinin g the on, standby, and off

- mode energy consumption values to provide an annual energy use . The format of the metric, expressed as annual energy consumption (AEC, kWh/year), would be as follows :113

AEC metric = ( ( P on * H on + P standby

- passive * H standby

- passive + P off * H off + DEC DAM )/1000 ) * 365

where: P m = power measured in a given mode m (in Watts) H m = hours per day spent in mode m DEC DAM = daily energy consumption in DAM, if applicable (tested according to the CEA DAM test procedure )

Proposed values for H m (in hours/ day ) would be as follows :

H on = 7 H standby

- passive = 17 H off = 0

To determine H on , DOE obtained Nielsen TV viewing statistics for the months June 2010 through May 2011. 38 Nielsen collected between 48,791 and 52,105 samples in each month, from a representative cross section of U.S. households. DOE separated the data for each household to consider the primary TV. The mean viewing hours per day for primary TVs was determined for each month, and then the mean across the whole 12 months was taken to provide the final value. It was important to consider 12 months, not just one, as there is significant seasonal variation in viewing habits.

38 The Nielsen Company, LL C (2011).114

It was assumed that the remainder of the time, TVs would be in standby

- passive mode (thus, H standby

- passive = 24

– H on ) , except for the case of TVs with DAM capability, where the average hours per day the TV is in DAM would also be included in the calculation. Therefore, H off = 0 is based on the assumption that virtually all TVs remain in standby mode rather than being physically switched off when not in use.

Note that P on is itself a weighted average of measurements for units with automatic brightness control available :

P on = P 10 * W 10 + P 5 0 * W 5 0 + P 100 * W 100 + P 300 * W 300

where: P i = on mode power measured at room illuminance of i lux W i = weighting at room illuminance i , expressed in percent.

W i are proposed to be equally weighted (W 10 = W 50 = W 100 = W 300 = 25 percent ) . See Section II III.E.4.b.i for further discussion and explanation.

The advantage of using a single metric is that the approximate annual average energy consumptio n can be calculated within the test procedure

. Although a single metric would require manufacturers to represent the efficiency of their TVs in a consistent manner, this is already being accomplished under the FTC Labeling Program for TVs as it is currentl y using this115

method

. A single metric would help harmonize the different voluntary, incentive, and State programs applicable to TVs. However, the DOE proposed single metric would most likely eliminate the current energy efficiency standards for TVs establis hed by California, since California established separate standards for both on mode and standby mode. All manufacturers would be required to make energy representations with the final DOE test procedure within 180 days after publication . After that time, m anufacturers would not be required to provide to California separate results for on mode and standby mode in accordance with the California standard. This single metric would also require a change in the ENERGY STAR Program for TVs, since ENERGY STAR als o has separate requirements for on mode, standby mode and DAM. T he DOE proposed single metric would require DOE to monitor how the coefficients used to calculate the metric change with consumer usage and technological advancements in the TV market

. F or ins tance, the average number of primary TV viewing hours has increased by approximately 0.16 hours per day each year from 2007 to 2011, or 10 percent over four years. Additionally, the single metric considered in this NOPR does not distinguish between different usage profiles for calculating annual energy consumption for types of TVs with different features included in our TV definition, such as computer monitors over 30 inches. Finally, the proposed single metric does not capture all measurements in t he test procedure such as power factor and illuminance ratio.

Although DOE is proposing multiple output metric s , it seeks comments from interested parties on both of the methods presented in this NOPR, including the use of a single metric for calculating a nnual energy consumption

IV. Procedural Issues and Regulatory Review

A. Review Under Executive Order 12866 The Office of Management and Budget has determined that test procedure rulemakings do not constitute “significant regulatory actions” under section 3(f) of Executive Order 12866, Regulatory Planning and Review, 58 FR 51735 (Oct. 4, 1993). According ly, this action was not subject to review under the Executive Order by the Office of Information and Regulatory Affairs (OIRA) in the Office of Management and Budget (OMB).

B. Review under the Regulatory Flexibility Act The Regulatory Flexibility Act (5 U.S. C. 601 et seq .) requires preparation of an initial regulatory flexibility analysis (IFRA) for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact o n a substantial number of small entities. As required by Executive Order 13272, “Proper Consideration of Small Entities in Agency Rulemaking,” 67 FR 53461 (August 16, 2002), DOE published procedures and policies on February 19, 2003, to ensure that the pot ential impacts of its rules on small entities are properly considered during the DOE rulemaking process. 68 FR 7990. DOE has made its procedures and policies available on the Office of the General Counsel’s website: ww w.gc.doe.gov

.
DOE reviewed today’s proposed rule under the provisions of the Regulatory Flexibility Act and the policies and procedures published on February 19, 2003. This proposed rule117

prescribes a test procedure to be used to develop and implement future energy conservation standards for TVs . DOE certifies that this proposed rule will not have a significant impact on a substantial number of small entities. The factual basis for this certification is as follows.

The Small Business Administration (SB A) considers an entity to be a small business, if, together with its affiliates, it employs less than a threshold number of workers specified in 13 CFR part 121. The thresholds set forth in these regulations are based on size standards and codes establishe d by the North American Industry Classification System (NAICS) 39 . TV manufacturers are classified under NAICS code 334220, “ Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing ,” and are considered small entities if they emp loy 750 employees or less.

DOE determined that most manufacturers of TVs are large multinational corporations. To develop a list of domestic manufacturers, DOE reviewed the Hoover database 40 and other publicly available data , including the Energy Star quali fied TVs database

. As a result of its review, DOE determined that there were no TV manufacturers who would qualify as small entities

. DOE also notes that manufacturers are already required to use a test procedure similar to DOE’s proposed test procedure to make energy representation s under the Federal Trade Commission’s EnergyGuide labeling program

. 76 FR 1038. DOE’s proposed test procedure can be conducted concurrently with FTC testing without significant additional burden

.

39 For more information visit: http://www.sba.gov/ . The size standards are available at http://www.sba.gov/sites/default/files/Siz e_Standards_Table.pdf

. 40 Hoovers. Web 12 Dec 2011. < http://www.hoovers.com/118

Based on the above, DOE certifi es that there would not be a significant impact on a substantial number of small entities and has not prepared an IRFA for this rulemaking. DOE transmitted the certification and supporting statement of factual basis to the Chief Counsel for Advocacy of the SBA for review under 5 U.S.C. 605(b). DOE requests comment on its conclusion that there are no small business manufacturers.

C. Review Under the Paperwork Reduction Act of 1995

There is currently no information collection requirement related to the test procedure for TV s. In the event that DOE proposes an energy conservation standard with which manufacturers must demonstrate compliance, DOE will seek OMB approval of such informat ion collection requirement.

DOE established regulations for the certification and recordkeeping requirements for certain covered consumer products and commercial equipment. 76 FR 12422 (March 7, 2011). The collection

- of

- information requirement for the certification and recordkeeping was subject to review and approval by OMB under the Paperwork Reduction Act (PRA). This requi rement was approved by OMB under OMB Control Number 1910

- 1400. Public reporting burden for the certification wa s estimated to average 20 hours per response, including the time for reviewing instructions, searching existing data sources, gathering and maint aining the data needed, and completing and reviewing the collection of information.119

As stated above, in the event DOE proposes an energy conservation standard for TVs with which manufacturers must demonstrate compliance, DOE will seek OMB approval of the associated information collection requirement . DOE will seek approval either through a proposed amendment to the information collection requirement approved under OMB control number 1910

- 1400 or as a separate proposed information collection requirement

.

Notwithstanding any other provision of the law, no person is required to respond to, nor shall any person be subject to a penalty for failure to comply with, a collection of information subject to the requirements of the PRA, unless that collection of inf ormation displays a currently valid OMB Control Numbe r.

D. Review Under the National Environmental Policy Act of 1969 In this proposed rule, DOE proposes a test procedure that it expects will be used to develop and implement future energy conservation standards for TVs. DOE has determined that this rule falls into a class of actions that are categorically excluded from review under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq .) and DOE’s implementing regulations at 10 CFR part 1021. Specifically, this proposed rule establishes a new test procedure without affecting the amount, quality or distribution of energy usage, and, therefore, wou ld not result in any environmental impacts. Thus, this rulemaking is covered by Categorical Exclusion A5 under 10 CFR part 1021, subpart D, which applies to any rulemaking that does not result in any environmental impacts . Accordingly, neither an environme ntal assessment nor an environmental impact statement is required.120

E. Review Under Executive Order 13132 Executive Order 13132, “Federalism,” 64 FR 43255 (August 4, 1999) imposes certain requirements on agencies formulating and implementing policies or regula tions that preempt State law or that have Federalism implications. The Executive Order requires agencies to examine the constitutional and statutory authority supporting any action that would limit the policymaking discretion of the States and to carefully assess the necessity for such actions. The Executive Order also requires agencies to have an accountable process to ensure meaningful and timely input by State and local officials in the development of regulatory policies that have Federalism implications . On March 14, 2000, DOE published a statement of policy describing the intergovernmental consultation process it will follow in the development of such regulations. 65 FR 13735. DOE has examined this proposed rule and has determined that it would not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. EPCA governs and prescribes Federal preemption of S tate regulations as to energy conservation for the products that are the subject of today’s proposed rule. States can petition DOE for exemption from such preemption to the extent, and based on criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further ac tion is required by Executive Order 13132.

F. Review Under Executive Order 12988 Regarding the review of existing regulations and the promulgation of new regulations, section 3(a) of Executive Order 12988, “Civil Justice Reform,” 61 FR 4729 (Feb. 7, 1996), im poses on Federal agencies the general duty to adhere to the following requirements: (1) eliminate drafting errors and ambiguity; (2) write regulations to minimize litigation; (3) provide121

a clear legal standard for affected conduct rather than a general sta ndard; and (4) promote simplification and burden reduction. Section 3(b) of Executive Order 12988 specifically requires that Executive agencies make every reasonable effort to ensure that the regulation: (1) clearly specifies the preemptive effect, if any; (2) clearly specifies any effect on existing Federal law or regulation; (3) provides a clear legal standard for affected conduct while promoting simplification and burden reduction; (4) specifies the retroactive effect, if any; (5) adequately defines key terms; and (6) addresses other important issues affecting clarity and general draftsmanship under any guidelines issued by the Attorney General. Section 3(c) of Executive Order 12988 requires Executive agencies to review regulations in light of applicable standards in sections 3(a) and 3(b) to determine whether they are met or it is unreasonable to meet one or more of them. DOE has completed the required review and determined that, to the extent permitted by law, the proposed rule meets the relevant standar ds of Executive Order 12988.

G. Review Under the Unfunded Mandates Reform Act of 1995 Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) requires each Federal agency to assess the effects of Federal regulatory actions on State, local, and Tribal gove rnments and the private sector

. Pub. L. No. 104

- 4, sec. 201 (codified at 2 U.S.C. 1531)

. For a proposed regulatory action likely to result in a rule that may cause the expenditure by State, local, and Tribal governments, in the aggregate, or by the private sector of $100 million or more in any one year (adjusted annually for inflation), section 202 of UMRA requires a Federal agency to publish a written statement that estimates the resulting costs, benefits, and other effects on the national economy. (2 U.S. C. 1532(a), (b)) The UMRA also requires a Federal agency to develop an effective process to permit timely input by elected officers of State, local, and Tribal122

governments on a proposed “significant intergovernmental mandate,” and requires an agency plan f or giving notice and opportunity for timely input to potentially affected small governments before establishing any requirements that might significantly or uniquely affect small governments. On March 18, 1997, DOE published a statement of policy on its pr ocess for intergovernmental consultation under UMRA. 62 FR 12820; also available at http:// www.gc.doe.gov

. DOE examined t oday’s proposed rule according to UMRA and its statement of policy and determined that the rule contains neither an intergovernmental mandate, nor a mandate that may result in the expenditure of $100 million or more in any year, so these requirements do not apply.

H. Review Under the Treasury and General Government Appropriations Act, 1999

Section 654 of the Treasury and General Government Appropriations Act, 1999 (Pub. L. 105

- 277) requires Federal agencies to issue a Family Policymaking Assessment for any rule that may affect family well

- being. This rule would not have any impact on the autonomy or int egrity of the family as an institution. Accordingly, DOE has concluded that it is not necessary to prepare a Family Policymaking Assessment.

I. Review Under Executive Order 12630 DOE has determined, under Executive Order 12630, “Governmental Actions and Inter ference with Constitutionally Protected Property Rights” 53 FR 8859 (March 18, 1988) that this regulation would not result in any takings that might require compensation under the Fifth Amendment to the U.S. Constitution.123

J. Review Under Treasury and General Government Appropriations Act, 2001 Section 515 of the Treasury and General Government Appropriations Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most disseminations of information to the public under guidelines established by each age ncy pursuant to general guidelines issued by OMB. OMB’s guidelines were published at 67 FR 8452 (Feb. 22, 2002), and DOE’s guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has reviewed today’s proposed rule under the OMB and DOE guidelines and has concluded that it is consistent with applicable policies in those guidelines.

K. Review Under E xecutive Order 13211 Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use,” 66 FR 28355 (May 22, 2001), requires Federal agencies to prepare and submit to OMB, a Statement of Energy Effects for any proposed signif icant energy action. A “significant energy action” is defined as any action by an agency that promulgated or is expected to lead to promulgation of a final rule, and that: (1) is a significant regulatory action under Executive Order 12866, or any successor order; and (2) is likely to have a significant adverse effect on the supply, distribution, or use of energy; or (3) is designated by the Administrator of OIRA as a significant energy action. For any proposed significant energy action, the agency must give a detailed statement of any adverse effects on energy supply, distribution, or use should the proposal be implemented, and of reasonable alternatives to the action and their expected benefits on energy supply, distribution, and use.124

Today’s regulatory ac tion to establish a test procedure for measuring the energy efficiency of TVs is not a significant regulatory action under Executive Order 12866. Moreover, it would not have a significant adverse effect on the supply, distribution, or use of energy, nor ha s it been designated as a significant energy action by the Administrator of OIRA. Therefore, it is not a significant energy action, and, accordingly, DOE has not prepared a Statement of Energy Effects.

L. Review Under Section 32 of the Federal Energy Administ ration Act of 1974 Under section 301 of the Department of Energy Organization Act (Pub. L. 95

– 91; 42 U.S.C. 7101), DOE must comply with section 32 of the Federal Energy Administration Act of 1974, as amended by the Federal Energy Administration Authorizati on Act of 1977. (15 U.S.C. 788; FEAA) Section 32 essentially provides in relevant part that, where a proposed rule authorizes or requires use of commercial standards, the notice of proposed rulemaking must inform the public of the use and background of suc h standards. In addition, section 32(c) requires DOE to consult with the Attorney General and the Chairman of the Federal Trade Commission (FTC) concerning the impact of the commercial or industry standards on competition.

The proposed rule incorporates t esting methods contained in annex C .3 and section 11 .5.5, 11.5.6, and 11.6 of the commercial standard , International Electrotechnical Commission 62087 Edition 2.0 2 0 11 , “Method of Measurement for the Power Consumption of Audio, Video and Related Equi pment;” section 5 .3.1 of the commercial standard, International Electrotechnical Commission 62301 Edition 2.0 2011 , “ Household electrical appliances

- Measurement of standby power” and CEA Procedure for Download Acquisition Mode Testing: For TVs,” Revision 0.3, September 8, 2010

. DOE has evaluated these standards and is unable to conclude125

whether they fully comply with the requirements of section 32 (b) of the Federal Energy Administration Act ( i.e. , whether they were developed in a manner that fully provid es for public participation, comment, and review).

As required by section 32(c) of the Federal Energy Administration Act of 1974 as amended, DOE will consult with the Attorney General and the Chairman of the Federal Trade Commission about the impact on competition of using the methods contained in these standards before prescribing a final rule.

E. Issues on Which DOE Seeks Comment Although DOE welcomes comments on any aspect of this proposal, DOE is particularly interested in receiving comments and views of interested parties concerning the following issues: 1. Scope of Coverage

– DOE seeks comments from interested parties on the proposed scope of this rulemaking , a s well as the definition of TVs

. Specifically, DOE would like
comments on including both TVs and displays greater than 15 inches which are sold with a TV tuner, and displays greater than 30 inches without a TV tuner in its definition

. (See section III.C ) 2. Light Measurement Devices

– DOE seeks comments from interested parties on the LMD equipment specifications proposed in this NOPR

. (See Section III.D.1.c ) 3. Signal Source and Generation

– DOE seeks comments from interested parties on the signal source and generation specified in this NOPR. (See section III.D.2.c ) 4. Picture Settings to Test

– DOE seeks comments from interested parties on its proposal to conduct luminance tests in home picture setting and retail picture setting . For testing on mode ene rgy consumption, DOE seeks comment on its proposal to test in home picture setting , along with its consideration to test on mode in both the highest and lowest energy132

consuming picture settings (or brightest or dimmest) , or all picture settings

. (See secti on III.E.1 ) 5. Luminance Testing

– DOE seeks comments from inte rested parties on its proposed method of luminance testing

. DOE also seeks comments on its proposal to include a luminance ratio. (See section III.E.3.b ) 6. Warm

- up and Stabilizatio n

– DOE seeks comments on the proposed method of taking the lumin an ce measurement immediately after displaying the three bar video signal

. (See section III.E.3.a ) 7. Video signal for Luminance Testing

– DO E seeks comments from interested parties on its proposal to use the three bar video signal for luminance testing

. DOE further seeks comments on any of the additional video signal s that it considered. (See section III.E.3.c ) 8. Room Illuminance Levels for T elevision Set s Shipped with A utomatic Brightness Control Enabled

– DOE seeks comments from interested parties on whether there should be a limit to th e reduction in display luminance achieved from ABC , and how a minimally acceptable display luminan ce value should be established.
