## Comparison of DOE’s Proposed Set

- top B ox Test Procedure with CEA

- 2043

This document compares DOE’s proposed test procedure for set

- top boxes (STBs) ( 78 FR 5075, January 23, 2013 ) to the test procedure specified in the Consumer Electronics Association’s (CEA) draft CEA

- 2043 standard, “Set

- top Box (STB) Power Measu rement”. The CEA standard was issued as an email ballot to members of the CEA working group for a vote on November 27, 2012

.

DOE’s proposed regulatory text is in the first column of the following table. The text that is in red font, highlights the text th at is different from (or in addition to) the CEA language. The second column lists the corresponding section of the CEA

- 2043 standard. Finally, the third column provides a brief explanation of the difference between DOE’s regulatory text and CEA’s language

. In this last column, a reference to the section
of the NOPR in which the topic is discussed in detail is also included.

Note that the page nu mber references are to the page numbers of the pre

- publication version of the DOE Notice of Proposed Rulemaking (NOPR) . In this document, the proposed regulatory text begins on page 130. The discussion section of the NOPR, page 14 to 101 of this

document , provides a detailed expla na tion of DOE’s proposal. I t should also be noted that the formatting of the pre

- publication NOPR is the
only difference between this version and the version published in the Federal Register. The text is the same.

2.6. Digital video recorder (DVR) means a STB feature that records television signals on a HDD 1 or other non

- volatile storage device integrated into the STB. A DVR often includes features such as: Play, Record, Pause, Fast Forward (FF), and Fast Rewind (FR). STBs that suppo rt a service provider delivery network

- based “DVR” service are not considered DVR STBs for purposes of this test procedure. The presence of DVR functionality does not mean the device
is defined to be a STB. 4.4 DOE a dded ‘integrated into STB’ to specify that STBs with
external HDDs are not tested as DVR STBs.

Discussed in section III.D. 4 of NOPR (Pages 30

. 2.25.2 S leep mode

– a range of reduced power states where the STB is connected to a mains power source and is not providing any principal STB function. The STB may transition to on or off mode due to user action, i nternal signal, or external signal. The power consumed in this mode may vary based on specific use or configuration. If any principal STB function is activated while operating in this mode, the STB is assumed to transition to on mode. Monitoring for user o r network requests is not considered a principal STB function.

T est Conduct

5.3. Test Conduct. The following section is provided as guidance when conducting the various on, sleep, and off mode tests. When multiple streams are enabled, different
content shall be selected to output to a display device, record on a DVR integrated into the STB, and stream to a
connected client.

5.3.1. Output to a Display Device. For tests requiring output to a display device, a channel shall be selected and viewed on the connected display devic e(s) as required by the test configuration. For STBs using a service provider that does not support channels, an appropriate SD or HD test stream
shall be selected and the content shall be viewed as
indicated. If more than one display device is connected t o the STB based on the test configuration from Table 1 (of the NOPR)

, then the content outputted on each display device
shall be different.

5.3.2. Recording for a STB with DVR capability

. For tests that require recording on a DVR, a channel shall be selected using a connected display device or a c lient and the program shall
be recorded. If more than one recording is enabled on a DVR that is integrated into the STB, the content for each

rec ording shall be different.

(continued) 8.2.2.1

. (b)

8.2.2.3 DOE adopted CEA’s on (watch TV) test for outputting to a

display device and made some modifications: DOE added additional requirement to stream different content on different display devices ; DOE did not include v iewing on
client specified in CEA

- 2043 because viewing on a connected display device is required for proposed STB
definition.

DOE referred to CEA’s on (record) test for recording on a
DVR STB and added requirement : to record different content if more than one recording is enabled.9 DOE Test Procedure CEA

- 2043 Comments on Differences

5.3.3. Streaming to a Connected Client. The content
streamed to a client shall be selected in the order of preference proposed in the NOPR depending on the number
of streams e nabled. The first available stream that is supported by each connected client shall be enabled and the
content on each stream shall be different.

5.3.3.1. Stream with recorded content. That is, previously recorded content shall be viewed on a display devi ce connected to a client

.

5.3.3.2. Stream with channel content. That is, a channel (SD stream for an SD client and HD stream for an HD client) shall be viewed on the connected display device. For clients that do not support channels, select an appropriate SD or HD test
stream and view the content as indicated

.

5.3.3.3. Other streaming option. If the streams from sections 5.3.3.1. and 5.3.3.2. (of the NOPR) are not supported, use
another stream that is available. 8.2.2.2

8.2.2.1 DOE r eferred to CEA’s on (play) and on (watch TV) tests for

streaming to a connected client and added requirement to
stream different content on each connected client.

Calculation of Average and Rated Power Consumption

5.4.1. For all tests in the on, sleep, and off modes (sections 5.5, 5.6, and 5.7), the average power shall be calculated using one of the following two methods:

5.4.1.1. Record the accumulated energy (E i ) in kilo

- watt hours (kWh) consumed over the time period specified for each test (T i ). The average power consumption is calculated

as P i = E i /T i .

5.4.1.2

. Record the average power consumption (P i ) by sampling the power at a rate of at least 1 sample per second and computing the ari thmetic mean of all samples over the time period specified for each test (T i ). 8.2.1. 8.3.1.(a) (e) (f) DOE a dded an additional method (the second method,

which is listed in section 5.4.1.2) to measure average power consumption

. The first method specified by DOE (section 5.4.1.1.) is similar to that specified in sections
