Final Report by
TV sets and Video Cassette Recorders Evaluation
Standard Subcommittee,
Energy Efficiency Standards Subcommittee ofAdvisory Committee for Natural Resources and Energy

The TV sets and Video Casset Recorders (VCR) Evaluation Standard
Subcommittee had deliberations on judgment standards for the manufacturers andimporters (hereafter referred to as "manufacturers ") concerning improvement in
performance of TV sets and Video Casset Recorders, and has made its final report as
below.
I.

TV sets

1.

Evaluation of Current Standard
The weighted average of energy consumption efficiency by shipment number of

TV sets (having cathode-ray-tube) whose target fiscal year was 2003 appeared
104kWh/year (for products shipped in the fiscal year 2003).

It is a 25.7%

improvement from 140kWh/year (for products shipped in the fiscal year 1997), whichis the weighted average of energy consumption efficiency by shipment number before
the introduction of the Top Runner Standard. This shows more improvement than theinitially expected energy consumption efficiency in the case of completion of the Top
Runner Standard (117kWh/year) and improvement rate (16.4%).
From the above, as a result of efforts for energy-saving by manufactures, it isevaluated that the energy-saving in TV sets has been progressed, and the current
standard based on the concept of the Top Runner Program functions effectively.
2.

Target Scope [See Attachment 1]
The Target scope shall include TV sets (limited to those having direct view tube

type cathode-ray-tube or liquid crystal panel using direct view type fluorescence-tube
backlight

orplasmadisplay

panel(hereafterreferredtorespectivelyas"cathode-ray-tube TV", "liquid crystal TV", and "plasma TV")) to be used byalternating-current (AC) electricity (rated frequency 50Hz or 60Hz, rated voltage
100V).
However, ones for industrial use, ones of specifications for tourists, ones forcathode-ray-tube multi-scan supported types with horizontal frequency exceeding
33.8kHz, rear projection types, ones of TV set size1 of below size 10 or size 10V,
wireless types, and plasma TVs whose number of vertical pixels exceeds 1080 shall be
excluded.

In this report, the receiver type size in cathode ray tube TV means the numeric value expressing
the cathode-ray frame dimensions in centimeters divided by 2.54 and rounded off to the decimal point(hereafter described as "○○ type"). And, in liquid crystal TV and plasma TV, it means the numericvalue expressing the driving display area’s diagonal dimension in centimeters divided by 2.54 androunded off to the decimal point (hereafter described as "○○V type").

Future Addition of Target Scope7

Toward the countrywide development of terrestrial digital broadcasting in 2006,
in liquid crystal TV and plasma TV, those with many numbers of pixels will become
the mainstream from the viewpoint of both high picture quality and large screen.
In consideration of the above trend, there is a high possibility that those "plasma
TVs whose vertical pixel count being 1080 or higher", which are excluded from thecurrent target, will be guradually shipped after 2005.
Therefore, judging from the shipment condition, when the sufficient number ofthe products is put in the market, evaluation of them shall be started to add them tothe target scope in a new standard.

II.

Video Casset Recorders

1.

Evaluation of Current Standard
The weighted average of energy consumption efficiency of Video Casset

Recorders (hereafter, VCR) whose target fiscal year was 2003 appeared 1.20 W ( forproducts shipped in the fiscal year 2003).

It is a 73.6% improvement from theweighted average of energy consumption efficiency (4.55 W) before the introduction of
the Top Runner Standard (for products shipped in the fiscal year 1997). This shows
more improvement than the initially expected energy consumption efficiency in thecase of completion of the Top Runner Standard (1.88 W) and improvement rate
(58.7%).
From the above, as a result of efforts for energy-saving by manufactures, it isevaluated that the energy-saving in VCR has been progressed, and the current
standard based on the concept of the Top Runner Program functions effectively.
2.

Target Scope [See Attachment 6]
The target scope shall include VCR or digital versatile disk recorder (hereafterreferred to as "DVD recorder"), to be used by AC electricity (rated frequency 50Hz or
60Hz, rated voltage 100V).
However, ones for industrial use, VCR with buit-in high-vision decoder, DVDrecorder (limited to ones without hard disk (hereafter referred to as "HDD") and VCR),
ones added with game function or server function, and ones having digital tuner shallbe excluded.

5.

Future Addition of target scope
Toward the countrywide development of terrestrial digital broadcasting in 2006,

it can be expected that, in DVD recorders, those with digital tuners will become themainstream.
In consideration of the above trend, there is a high possibility that those "withdigital tuners" that have been out of the current target will rapidly increase theshipment number after 2005.
Therefore, judging from the shipment condition, when the sufficient number ofthe products is put in the market, evaluation of them shall be started in 2005 to add
them to the target scope.

13

Attachment 1
Target Scope of TV Sets
The criteria shall apply to TV sets (limited to those having direct view tube type
cathode-ray-tube or liquid crystal panel using direct view type fluorescence-tube
backlight or plasmadispaly panel) that are utilized for AC electricity (rated frequency
50 or 60 Hz, rated voltage 100V).

However, the following shall be excluded from thescope.
1. TV Sets for Industrial Use
The equipment for broadcasting stations and those that are used for industrial
purposes and have special specifications shall be excluded from the scope, becauseof their limited specifications and small shipment volume.
2. TV Sets with Extremely Low Market Share- TV sets for tourists (Volume of shipments in 2003: 1,015 sets)- Cathode-ray tube TV sets of multi-scan supported types whose horizontal
frequency exceeds 33.8 kHz (Volume of shipments in 2003: 4,397 sets)- TV sets of rear projection types (Volume of shipments in 2003: 6,171 sets)- TV sets whose size is type 10, type 10V or lower (Volume of Shipments in 2003:
21,105 sets)- TV sets of wireless types (Volume of shipments in 2003: 31,119 sets)- Plasma televisions having the vertical pixel count being 1080 or higher (Volumeof shipments in 2003: 0 set)
Consumer needs have not yet been defined for the equipment listed above that,in general, have a few models or even no model commercially available in the market.
Depending on future developments, however, we shall conduct a necessary review
when it is considered appropriate to include them in the scope.
Note 1: Monitors sold by theirselves only shall be included in the target, only if they are capable of
TV reception by being combined with a tuner of the same manufacturer.
Note 2: Display monitors for a personal computer and having the capability of TV reception shall be
excluded from the target.

Target Fiscal Year and Others for TV Sets
1.

In general, a considerable improvement in energy consumption efficiency of
TV sets is made when a model change takes place, and a typical development
period of these new products is approximately 2 years.

For this reason,

consideration should be given so that the manufacturers can take at least twoopportunities of bringing out new models before the next target fiscal year.
On the other hand, in light of measures against global warning, in order toensure that products that achieved the target standard value become widely usedamong consumers during the first commitment period of Kyoto Protocol (2008 to
2012), it would be desirable to achieve the target in as short time as possible,
assuming that the tenure of use of TV sets would be approximately 10 years.
With the above in mind, the target fiscal year of liquid crystal display
televisions (LCD TV) and plasma televisions, which are newly added to the target
scope, shall be set to 2008; that is three years after establishment of the criteria.
In addition, the target fiscal year for cathode-ray tube televisions that havealready been covered in the target scope shall be the same as at present (fiscal year
2003 and each year after).
2.

In addition, the improvement rate of energy consumption efficiency by thetarget fiscal year (excluding cathode-ray tube televisions) is expected to beapproximately 15.3% based on the assumption that there will be no change fromthe current volume of shipment or compositions in each category (the resut in 2004
and prospect partially included).

<Overview of Estimation (only for LCD and plasma televisions)>(1) Energy consumption efficiency estimated from the actual achievement valuesof TV sets shipped in 2004: 142.3 kWh/year(2) Energy consumption efficiency estimated from the target standard values ofTV sets to be shipped in the target fiscal year: 120.5 kWh/year(3) Improvement ratio of energy consumption efficiency(142.3 - 120.5)

Among TV Sets, cathode-ray tube televisions were designated as specified

equipment for the Top Runner Standard in 1999.

However, since then, with the riseof new types of televisions such as liquid crystal display televisions (LCD TVs) or
plasma televisions that have different display devices, the shipment number of thecathode-ray tube televisions has dramatically dropped.
In consideration of the fact that the market of cathode-ray tube type TVs has
shrunk as described above and that digitalization is progressing, ones with the built-in
digital broadcasting recepter or with the built-in DVD are expected to increase.
This is because we shall make some modifications concerning addition of newdevices, while maintaining the present classification as a basis.
Because, due to differences in display devices they use, LCD and plasma
televisions have a substantial impact on energy consumption efficiency (i.e., annual
energy consumption, the same hereinafter) and technologies to be introduced in the
future, those televisions shall be classified accordingly.

In addition, as an aspect ratio(fineness ratio), pixel count, form of broadcasting that can be received, and availabilityof additive functions, etc., influence the energy consumption efficiency, theclassification shall be made according to them also.
II. Specific Classification Method
TV Sets can be roughly divided into (1) cathode-ray tube televisions, (2) LCD(liquid crystal televisions), and (3) plasma televisions, according to display devices.
Since not only differences in the display devices have a broader impact on the energy
consumption efficiency, but also substances of development of energy saving
technologies in the future will differ among them, it would be reasonable to classify
television sets based on the type of display devices (See Figure 1).

1. Cathode-ray Tube Televisions
As discussed earlier, we shall make some modifications to the classification of
the current regulation for the cathode-ray tube TVs based on changes incomposition ratio of shipments and addition of a new target, etc. To be specific,
with declining volume of shipments of the cathode-ray tube TVs, the productstructure is shifting towards television sets with built-in digital broadcasting
reception. Hence, although we basically maintain the present classification (inother words, television sets that can support digital broadcasting shall also be
included in the category of TV sets supporting analog broadcasting under thepresent classification), we have clearly separated the category of high-vision TVs
that are supposed to receive analog broadcasting according to their definition, so as
to avoid confusing them with the television sets that support digital broadcasting
reception. In addition, taking into consideration that the number of those withbuilt-in DVD is rising, we shall change what is specified as “VCR” under thepresent classification to “VCR (or DVD)” (See III).

2. Liquid Crystal Display (LCD) Televisions(1) Classification by Aspect Ratio (Fineness Ratio)
Similar to cathode-ray tube televisions, there are two types of LCD
televisions: those with the aspect ratio of 4:3 and those with the aspect ratio of 16:9
(wide screen TVs).

Their screen areas differ even in the same screen size, thus

they fluence energy consumption efficiency.

Therefore, we shall classify them asfollows.
Proposal for Classification:(1) LCD TVs with the aspect ratio of 4:3(2) LCD TVs with the aspect ratio of 16:9
(2) Classification by Pixel CountThe pixel count should be increased to balance better picture quality andlarger screen size in LCD televisions.

Thus, even before the full-scale operation ofdigital broadcasting, TV sets with the higher pixel count are gradually becoming
the mainstream.

Typical panels by the pixel count are as follows.

-Panels with the vertical pixel count being less than 650... Equivalent of VGA (Video Graphics Array)-Panels with the vertical pixel count being 650 or more but less than 1080... Equivalent of XGA (Extended Graphics Array)-Panels with the vertical pixel count being 1080 or more
… Equivalent of FULL-HD (FULL-High Definition)
As such differences in the pixel count have an effect on luminance of thescreen, brightness of backlights, and the energy consumption efficiency, we shallclassify according to it (See Figure 2).
Note that as there is no TV sets with aspect ratio of 4:3 that use liquid crystal
panels equivalent to FULL-HD, and as no future shipment of them is expected,
classification by being equivalent of FULL-HD will not be made.
Proposal for Classification(1) Panels with the vertical pixel count being less than 650.
(2) Panels with the vertical pixel count being 650 or more but less than 1080.
(3) Panels with the vertical pixel count being 1080 or greater.

Figure 2: Relationship of Pixel Count and Annual Energy Consumption (LCD TV)(3) Classification by Receivable Form of Broadcasting
Prior to full-scale operation of terrestrial digital broadcasting from 2006, TV
sets that can receive only analog broadcasting and those that can receive both
digital and analog broadcasting are mixed in the current market.

Compared withthe analog broadcast receivers, the digital broadcast receivers have a number offunctions that the conventional analog broadcasting receivers do not have, such asdata broadcasting, bidirectional functions, conditional access system (scramble
broadcast), etc., as well as digital video/audio processing, which considerablyincrease a scale of the circuits (to be specific, an error correction circuit, MPEG
decoder circuit, descrambler circuit, etc.). Since a difference in the circuit scale
has an impact on the energy consumption efficiency or future technologicaldevelopment, we shall classify them by the receivable form of broadcasting (SeeFigure 3).
In addition, for LCD televisions with the aspect ratio of 4:3, even with the
spread of digital broadcasting (to be broadcasted at 16:9) in the future, the models
that can only support analog broadcasting are expected to be the mainstream.
Thus, we shall not classify them by the form of broadcasting.
Among LCD televisions with the aspect ratio of 16:9, for those having thevertical pixel count of 1080 or greater, at present, there is only one model available
which supports analog broadcasting only, and the number of the similar models is

19

not expected to grow in the future. Thus, we shall not classify them by the form of
broadcasting.

(4) Classification by Availability of DVD Play Function
Many of the LCD televisions with 4:3 have a small TV size, and they areoften equipped with DVD for play only as an additive function.

For their case, it

is believed that energy consumed by DVD play function accounts for a relatively
large share of the annual energy consumption; thus, it would be difficult tocompensate possible increase of the annual energy consumption attributed to theincrease of additive functions by technological advancement in the future.

Hence,

we shall classify those TV sets by availability of DVD play function only.

Notethat we shall sort out DVD record function as an “additive function” (to be
discussed later).
Proposal for Classification(1) LCD TVs with DVD play function only20

(2) LCD TVs other than ones with DVD play function only
(5) Classification by Additive Function
LCD TVs are equipped with various additive functions. When they arebuilt into the LCD TVs, they influence the energy consumption efficiency.

If weclassify those televisions ignoring these additive functions, as a result, it is likelythat ones with additive functions may no longer be produced, and then it might
unduly interfere with various needs in the market.

For this reason, theclassification shall consider major additive functions.

In light of the current

product structure, we shall only address the following major additive functions: (1)“Digital Versatile Disk (DVD) (limited to those capable of recording)”, (2) “Hard
Disk (HDD)”, and (3) “Double Digital Tuner”.

We shall not include functions

other than the above in the classification, while expecting their technologicaladvances in the future.
In addition, for LCD TVs with the aspect ratio of 4:3 that is capable of DVD
play only, although they otherwise need to be classified by these additive functions,
we shall classify them only by availability of HDD, because LCD TVs with built-in
DVD capable of recording do not exist, and also because they support analog
broadcasting (as stated in (3) above).
Proposal for Classification(1) LCD TVs other than those listed below(2) LCD TVs with one additive function(3) LCD TVs with two additive functions(4) LCD TVs with three additive functions (as this classification is limited tothose with double digital tuner, it shall be only set for those that can receive
digital broadcasting)*)The additive functions herein refer to 3 functions, “DVD (limited to those capable ofrecording)”, “HDD”, and “double digital tuner (there should be more than one identical
digital broadcast receiving tuners)”.

(6) Classification by TV Set Size
For LCD TVs, because of their structure, those with a smaller TV set size
have a smaller backlight fluorescent lamp.

Thus, it not only degrades efficiency,

but also deteriorates the aperture rate (transmissivity) resulting in lower

21

luminance of the LCD panel for those with the same pixel count.

As it isnecessary to make the backlight brighter in order to solve this problem, theyrequire more electric energy.

As a result of studying data of the present

equipment, we found that a relationship of TV set size and annual energy
consumption undergoes a change in the vicinity of 15V type (See Figure 4).

If weclassify LCD TVs under 15V type and those 15V type and above into the same
category, it is more likely that the former can no longer be produced inspite of theneeds in the market. Thus, we shall separate those under 15V type from those
15V type and above.
Note that TV set size in LCD TVs refers to a numeric value expressing thedriving display area’s diagonal dimension in centimeters divided by 2.54 androunded off to the decimal point.

It is so-called ○○V type.

As no plasma TVs with 4:3 currently exist and will exist in the future, we shall not

classify them by the aspect ratio.
(2)

Classification by Pixel Count
Although, similar to the case of LCD TVs, it is appropriate to classify plasma

TVs by the pixel count, it shall not take place due to the following reasons: because
there are only 4 models available having the vertical pixel count of less than 650(equivalent of VGA), because there is no model available having the vertical pixel
count of 1080 or higher, and because a majority of them have the vertical pixel
count of 650 or higher and less than 1080 (equivalent of XGA) (See Figure 5).

unduly interfere with various needs in the market.

product structure, we shall only address the following major additive functions: (1)“Digital Versatile Disk (DVD) (limited to those capable of recording)”, (2) “Hard

other than the above in the classification, while expecting their technologicaladvances in the future.

digital broadcast receiving tuners)”.

(5) Classification by TV Set Size
For plasma TVs, measurement of the present equipment has revealed thatthe slope of a graph showing a correlation of TV set size and annual energy
consumption significantly changes in the vicinity of TV set size of 43V type (SeeFigure 7).

As the annual energy consumption per TV set size rapidly increases forthe ones of 43V type and above, we shall separate plasma TVs under 43V type fromthose 43V type and above.
Note that TV set size in plasma TVs refers to a numeric value expressing thedriving display area’s diagonal dimension in centimeters divided by 2.54 androunded off to the decimal point.

Target Standard Values for Television Sets
I.

Idea on Establishment of Target Standard Values

1. Basic Idea
We shall set target standard values based on the idea of Top Runner Method.
The specific policy shall be as follows.
(a) Target standard values should be set for every category that has been
appropriately defined.
(b) As for the categories where future technological advances are expected to
improve efficiency, the target standard values should allow for the
improvement as much as possible.
(c) Target standard values should not conflict among categories.
2. Flow of Setting Target Standard Values
Annual energy consumption of TV Sets (cathode-ray tube TVs, liquid crystal
display TVs, and plasma TVs) has a positive correlation with TV set size (SeeFigure 1 to 3).

Thus, in a given category, if we simply set a value of a model withless annual energy consumption as a Top Runner Standard, it is more likely thatmodels with larger TV set size may no longer be produced, which unduly interfereswith various needs of the market.

With the above in mind, we shall express

target standard values (annual energy consumption) by linear function formulae(calculation formulae) with the TV set size as a variable. (However, we shallexclude LCD TVs with the aspect ratio of 4:3 having the TV set size under 15V.
This is to be discussed later.)

We shall develop the calculation formulae asfollows.
In addition, we shall define TV set sizes as below.
(1)Cathode-Ray Tube TVs
The TV set size of cathode-ray tube TVs refers to the numeric value
expressing the cathode-ray frame dimensions in centimeters divided by 2.54
and rounded off to the decimal point.

(2)

It is so-called ○○type.

Liquid Crystal Display (LCD) TVs and Plasma TVs
The TV set size of LCD and plasma TVs refers to the numeric value
expressing the driving display area’s diagonal dimension in centimeters29divided by 2.54 and rounded off to the decimal point. It is so-called ○○type.
(1) Cathode-Ray Tube TVs
Among TV Sets, cathode-ray tube TVs were designated as specified
equipment for the Top Runner Standard in 1999.

However, since then, with therise of new types of TVs such as liquid crystal display TVs (LCD TVs) or plasma
TVs that have different display devices, the number of the cathode-ray tube TVs is
expected to drop dramatically.

In addition, while various manufacturers arefocusing their efforts for technological development on LCD TVs or plasma TVs,
further improvement in the efficiency of cathode-ray tube TVs is unlikely as its
technological development is no longer expected in the future.
In light of the above, we decided to leave the target standard values forcathode-ray tube TVs unchanged.
(2) Liquid Crystal Display (LCD) TVs
First, a correlation slope of TV set size and annual energy consumption shallbe determined for each of the aspect ratio, pixel count, and receivable form of
broadcasting.

Then, under the slope, the calculation formula is set for eachcategory so that the intercept will be a minimum.

Lastly, the target standard

value shall be finalized by allowing for possible improvement that is expected by
the target year.
(3) Plasma TVs
First, a correlation slope of TV set size and annual energy consumption shallbe determined for each of the TV set size and receivable form of broadcasting.
Then, under the slope, the calculation formula is set for each category so that theintercept of the calculation formula will be a minimum.

Lastly, the target

standard value shall be finalized by allowing for possible improvement that is
expected by the target year.
3. Addressing Categories in which No Models Exist
We have decided to classify LCD and plasma TVs by the number of additive
functions. There are a number of categories with the relevant additive functions,in which no models do exist, however. Therefore, it is impossible to set target
standard values based on real Top Runner values for those categories.

30

On theother hand, due to advancing digitalization in the future, LCD TVs and Plasma
TVs with those additive functions in these categories are expected to increase.
Thus, when setting the target standard values for them, we should first calculatepossible increase in annual energy consumption attributable to built-in additive
functions, with the following approach.

Then, by adding the increase to Top

Runner Value for the basic specification and without additive functions category,
we shall define the target standard values.
For TVs with built-in HDD or DVD (recording), to find the value to be added,
we calculate the difference in annual energy consumption of the models that are of
the same type/size and made by the same manufacturer but only different in theavailability of HDD or DVD (recording).
For double digital tuners, there are no models available made by the same
manufacture and only different in the availability of double digital tuners.
Therefore, we calculate the difference in averages of annual energy consumption ofmodels that are of the same type/size but only different in the availability of digital
double tuners.

Difference: 430Difference: 30

We learned from (1) and (2) above that the energy consumption increases by 18
to 20 kWh for TV sets with built-in HDD or DVD (recording), and by 30 to 43 kWh for
TV sets with built-in double digital tuners, respectively. We need to set additional
values based on the increases.

As those with built-in HDD or DVD (recording) are

relative newcomers in the market, the future improvement in energy consumption
efficiency due to technological development can be expected.

Also, for those withdouble digital tuners, there might be other possible factors for the increase because
these models we compared were from different manufacturers.

In addition, for theboth types of TV sets, from the standpoint of energy saving, all possible power-saving
efforts through technological development is desired.

For these reasons, we decided

to set a uniform target standard value of 15kWh for these categories.
Compared with the method of determining target standard values in accordancewith measurements, the decision to uniformly introduce the above additional value of
15 kWh could encourage the manufacturers to make more energy-saving efforts (i.e.,
stricter standard values would be set), even for the categories of TV sets with additive
functions where models are currently available.

Hence, in determining target

standard values for these categories, we shall adopt the same method with addional

32

values described above, irrespective of whether or not models currently exist in thosecategories.
II. Room for Improvement in Energy Consumption Efficiency Through Technological
Advance in the Future
Development of technologies in LCD and plasma TVs has been carried out,
mainly intending to optimze image quality for the digital age and to improve userconvenience such as thinner screen and longer operating life.

Overall, technologicaldevelopments towards higher energy consumption efficiency have just begun, although
there are some differences among manufacturers.

In other words, a room for

improvement in efficiency still remains for LCD and plasma TVs.
LCD TVs are expected to raise the efficiency by higher transmissivity of a liquid
crystal panel, less power consumption of backlight fluorescent tubes, optimal control ofbacklights, etc.; whereas, plasma TVs are expected to improve the efficiency throughmodification of PDP panel structure (optimization of gas partial pressure ratio or rib
structure), higher emmision efficiency of fluorescent substance, reduced reactive
power, etc.

Taking into our consideration that these factors may contribute to higher

efficiency, we set the target standard values by 5% up from the current Top Runner
Value.
When the Top Runner Value is a numerical value, we shall set the target
standard value simply by reducing it by 5%.

When the Top Runner Value is acalculation formula according to TV set size, in order to proceed with energy saving ofoverall TV sets effectively as well as to eliminate the possibility of limiting consumer
needs, the target standard value will be set with the formula with a slope obtained
from the value of actual measurements allowing efficiency improvement, which istranslated until the intercept become minimized.

Simple translation of the original

formula downward by a uniform rate of 5% would not be taken, because wide
fluctuation of energy consumption efficiency according to TV set size (the steeply
inclined linear function of TV set size and annual energy consumption) would result increating a lenient demand of efficiency improvement for larger sized TVs while
creating a strict demand for smaller sized TVs.
III. Specific Target Standard Values(1) Cathode-Ray Tube TVs
As stated above, we shall leave the target standard value for this category
unchanged.

33

(2) LCD TVs(a) LCD TVs with the aspect ratio of 4:3 and the vertical pixel count of less than 650(Category 21 to 30)
For the ones being under 15V type, if we classified them into the same
category as that for those 15 type and above, it would become extremely difficult
for them to achieve the target standard value, and it would also limit the market
needs, as described in Attachment “II”, “2.”, (6).

It has been found from the datathat influence of TV set size is relatively small in the relationship with annual
energy consumption of LCD TVs under 15V type. Thus, we decided to ignore
possible effect of TV set size and, instead, to set the smallest value of the annual
energy consumption as the Top Runner Value, for each of those with or without
DVD play function. First, based on actual measurements, we decided the Top
Runner Value for those of basic specification (Category 21, 24) (See Figure 5).
Then, for the category with additive functions, as we stated earlier, we
calculate the Top Runner Value by adding 15kWh for each additive function.
Lastly, we determined the target standard value by including the possible
improvement in efficiency of 5% into the Top Runner Value (See Figure 5).
For LCD TVs of 15V type and above, we found the correlation slope between
TV set size and annual energy consumption from the data of those having thelowest annual energy consumption for each TV set size, among those with the basic
specification without DVD play function (Category 26, those without additive
functions) (See Figure 4).

Then, we determined the calculation formula of the Top

Runner Value with the slope by adopting the intercept of the one having the lowest
annual energy consumption, for each LCD TV of basic specification with or without
DVD play function (Category 26, 29).
For the categories with additive functions, we determined the calculation
formula by adding 15 kWh per additive function to the intercept of the calculation
formula of the Top Runner Value for LCD TVs of basic specification.
Finally, the calculation formula that is obtained from combining the
calculation formula of the Top Runner Value and possible improvement inefficiency of 5% according to the approach described above (“II”) (i.e., translating
the original Top Runner Value downward by 5% with the slope multiplied by 0.95)
is set for the target standard value(See Figure 5).
Then, since the target standard value (E=69) of those under 15V type with
DVD play function is higher than that (E=58) of those of 15V type which is
obtained from the calculation formula (E=5.9S-31) for those 15V type and above34

(i.e., inverse correlation), we decided to set the value of 15V type (E=58) as thetarget standard value for the category of under 15V type with DVD play function.

and less than 1080 (Category 31 to 40)
For LCD TVs under 15V type, similar to (1) above, if we classified them into
the same category as that for those 15 type and above, it would become for themextremely difficult to achieve the target standard value and also would limit themarket needs, as described in Attachment “II”, “2.”, (6).

It has been found fromthe data that influence of the TV set size is relatively small in the relationship withannual energy consumption of those under 15V type.

Thus, we decided to ignore

possible effect of TV set size and to set the smallest value of the annual energy
consumption as the Top Runner Value, for each of those with or without DVD playfunction.
First, based on actual measurements, we decided the Top Runner Value for36those of basic specification (Category 31, 34).
Then, for the category with additive functions, as we stated earlier, we
calculate the Top Runner Value by adding 15kWh for each additive function.
Lastly, we determined the target standard value by including the possible
improvement in efficiency of 5% into the Top Runner Value (See Figure 7).
Also for LCD TVs above 15V type, similar to (1) above, we found thecorrelation slope between TV set size and annual energy consumption from thedata of those having the lowest annual energy consumption for each TV set size,
among those with the basic specification without DVD play function (Category 36,
those without additive functions) (See Figure 4).

Then, we determined thecalculation formula of the Top Runner Value with the slope by adopting theintercept of the one having the lowest annual energy consumption, for each LCD
TVs of basic specification with or without DVD play function (Category 36, 39).
Then, for the categories with additive functions, as we stated earlier, we
determined the Top Runner Value by adding 15 kWh per additive function.
Finally, the calculation formula that is obtained from combining the
calculation formula of the Top Runner Value and possible improvement inefficiency of 5% according to the approach described above (“II”) (i.e., translating
the original Top Runner Value downward by 5% with the slope multiplied by 0.95)
is set for the target standard value(See Figure 7).

Limited availability of models in these categories (namely, 1 model
supporting only analog broadcasting and 2 models (in the same size) supporting
digital broadcasting) did not allow us to determine a correlation slope of respective
TV set sizes and annual energy consumption. Thus, alternatively, we used theslope determined from the data of those having the lowest annual energy
consumption for each TV set size, among both analog and digital LCD TVs of thebasic specifications having the vertical pixel count of 650 or higher and less than1080, which will be described in (4) below (See Figure 8 and 9).

Then, wedetermined the calculation formula of the Top Runner Value with the slope byadopting the intercept of the one having the lowest annual energy consumption, foreach category of analog-supporting and digital-supporting LCD TV of basic
specification (Category 41, 44) (See Figure 10).
For the categories with additive functions, we determined the Top Runner
Value by adding 15 kWh per additive function to the Top Runner Value for theones of basic specification.
Finally, the calculation formula that is obtained from combining the
calculation formula of the Top Runner Value and possible improvement inefficiency of 5% according to the approach described above (“II”) (i.e., translating
the original Top Runner Value downward by 5% with the slope multiplied by 0.95)
is set for the target standard value(See Figure 10).

We determined a correlation slope of TV set size and annual energy
consumption from the data of those having the lowest annual energy consumption
for each TV set size, among each analog-only-supporting and digital-supporting
LCD TVs of the basic specifications (Category 48, 51).

As for this category, only 3 models have just entered the market, and acorrelation of TV set size and annual energy consumption of these 3 models would
have a extremely steep inclination.

Setting the target standard value based on

the correlation would make it extremely difficult to achieve the target standard
value for the LCD TVs in the categories under 37V type that have currently no
product on the market but are expected to grow with advancing digitalization in
the future. In addition, future engineering development in these categories is40

unclear.

Thus, the slope shall be determined with the following approach, rather

than using actual measurements.
Because of their structure, brightness of the backlight need to be improved tocompensate for a drop of transmittance (decreased numerical aperture) due toincreased pixel count.

In addition, power consumption of liquid crystal drive

circuits and image circuits need to be improved by accelerating speed of signal
processing.

In theory, the models in these categories are expected to consume

energy by about 1.2 times as TV set size increased, compared with the models
described in (d) above. Thus, we adopted the value 9.4 as the correlation slope ofTV set size and annual energy consumption, which is obtained by multiplying theslope of digital-supporting LCD TVs in (d) above by 1.2 (See to Figure 12).
We determined the calculation formula of the Top Runner Value with theslope by adopting the intercept of the one having the lowest annual energy
consumption, among the ones of basic specification (Category 55) (See Figure 13).
For the categories with additive functions, we determined the Top Runner
Value by adding 15 kWh per additive function to the Top Runner Value for theones of basic specification.
Finally, the calculation formula that is obtained from combining the
calculation formula of the Top Runner Value and possible improvement inefficiency of 5% according to the approach described above (“II”) (i.e., translating
the original Top Runner Value downward by 5% with the slope multiplied by 0.95)

Function(3) Plasma TVs
Similar to LCD TVs, in the case of plasma TVs, those receiving analog

41

broadcasting only and those capable of receiving digital broadcasting are mixed in
the market.

However, the former is generally of old type, and many

manufacturers focus the effort on development of the latter.

Therefore, it seems

inappropriate to find a correlation slope of TV set size and annual energy
consumption from the data of those receiving analog broadcasting only.

Thus,with respect to the slope, we shall uniformly apply the slope of those capable ofreceiving digital broadcasting.
(a) Plasma TVs under 43 V type, receiving analog broadcasting only (Category
59 to 61before integration)(b) Plasma TVs under 43 type, capable of receiving digital broadcasting(Category 62 to 65 before integration)
For (a) and (b) above, we determined the correlation slope of TV set size andannual energy consumption from the data of those having the lowest annual
energy consumption for each TV set size, among the ones of the basic specification
and being capable of receiving digital broadcasting (Category 62 before
integration).

Note that as the correlation changes around 43V type, we include d

the data of 43V type to determine the correlation slope (See Figure 14).

Then, wedetermined the calculation formula of the Top Runner Value with the slope byadopting the intercept of the one having the lowest annual energy consumption, foreach category of analog-supporting and digital-supporting LCD TVs of basic
specification (Category 59, 62 before integration) (See Figure 15).
For the categories with additive functions, we determined the Top Runner
Value by adding 15 kWh per additive function to the Top Runner Value for theones of basic specification.
Then, the calculation formula that is obtained from combining the calculation
formula of the Top Runner Value and possible improvement in efficiency of 5%
according to the approach described above (“II”) (i.e., translating the original Top
Runner Value downward by 5% with the slope multiplied by 0.95) is set for thetarget standard value (See Figure 15).
Since the target standard value (E=7.9S+32) of those receiving analog
broadcasting only in (a) is higher than that (E=7.9S+30) of those capable ofreceiving digital broadcasting in (b) (i.e., inverse correlation), we decided to set thelatter (E=7.9S+30) as the target standard value for the category of thosereceiving analog broadcasting only.
(c) Plasma TVs above 43 V type, receiving analog broadcasting only (Category42

66 to 68 before integration)(d) Plasma TVs above 43 type, capable of receiving digital broadcasting(Category 69 to 72 before integration)
For (c) and (d) above, if we find the correlation slope of TV set size and annual
energy consumption from the data of those having the lowest annual energy
consumption for each TV set size among those of the basic specification and(Category 69 before integration), the slope would be steep; and setting the target
standard value based on the slope might result in creating a lenient target
standard for larger screen TV sets. This is because some 43V type and 50V typetelevisions have particularly less annual energy consumption.

So far the screensof plasma TVs have kept getting bigger, and in order to effectively cope with theincrease in energy consumption attributed to the tendency, we consciously decided
to find the slope based on those 2 types of plasma TVs with better efficiency (SeeFigure 16).
For the categories with additive functions, we determined the Top Runner
Value by adding 15 kWh per additive function to the Top Runner Value for theones of basic specification.
Then, the calculation formula that is obtained from combining the calculation
formula of the Top Runner Value and possible improvement in efficiency of 5%
according to the approach described above (“II”) (i.e., translating the original Top
Runner Value downward by 5% with the slope multiplied by 0.95) is set for thetarget standard value (See Figure 16).
Since the target standard value (E=15.9S-263) of those receiving analog
broadcasting only in (c) is higher than that (E=15.9S-329) of those capable ofreceiving digital broadcasting in (b) (i.e., inverse correlation), we decided to set thelatter (E=15.9S-329) as the target standard value for the category of thosereceiving analog broadcasting only.
Consequently, since the identical values are applied to the target standard
values for both analog-only-supporting and digital-supporting plasma TVs, we
integrate the categories of these plasma TVs.

Energy Consumption Efficiency of TV Sets and Method for Measurement
1. Basic Idea
As for TV sets, when they were designated as specified equipment of the Top
Runner Standard in 1998, “Annual Eenery Consumption” was introduced as a realistic
indicator of energy consumption efficiency.
It is reasonable to continue to use it as the relevant indicator of energy
consumption efficiency of TV sets, because of no particular technical flaw and its
intelligibleness.
In addition, as far as cathode-ray tube televisions are concerned, there would be
no particular problem in continuously using the conventional measuring method.
Thus, amendment to the measuring method accompanying this review are mainly
attributed to plasma and LCD televisions which are newly added to the target scope.
2. Specific Energy Consumption Efficiency and Measuring Method
The energy consumption efficiency of TV sets shall be “Annual Energy
Consumption”, and shall be a numeric value [kWh/year] calculated with the following
equation:E = {(PO - PA / 4) × t1 + PS × t2} / 1000
In this equation, E, Po, Ps, PA, t1 and t2 shall represent the following numericvalues.
E:

annual energy consumption (kWh/year)Po:

operational power (Watt)Ps:

standby power (Watt)PA:

reduced power consumption by energy-saving function (Watt)t1:

annual standard operating time (hour) 1642.5 (365 days × 4.5 hours)*

t2:

annual standard standby time (hour) 7117.5 (365 days × 19.5 hours)** We shall use conventional values of t1 (annual standard operating time) and t2(annual standard standby time), as there is no pronounced change in the actual
status of the usage of TV sets.

57

(1) Po: operating power (W)The operating power shall be the mean value of power consumption of flatlevel white signal (Pw) and that of flat level black signal (Pb).

Note, however,that for LCD and plasma TVs, the operating power shall be obtained by taking
the mean of the aforementioned power consumption values plus those of color bar
signal (Pc) and three-vertical-strip signal (Pt).

The measurement shall takeplace while the energy-saving function is inactive. (*)(a) In the case of cathode-ray tube TVs: PO = (Pw + Pb) / 2(b) In the case of plasma and LCD TVs: PO = {(Pw + Pb) / 2 + Pc + Pt} / 3
In addition, for TV sets designed to have different power consumption
depending on input signals, power consumption should be measured with each ofthem, and the mean of the maximum and minimum values shall be taken as theoperating power.
PO = (POMax + POMin) / 2* Unlike in case of cathode-ray tube TVs, the operating power of LCD and plasma
TVs tends to be smaller than that in actual use, when it is the mean of power
consumption of flat level white signal and that of flat level black signal. For thisreason, for LCD and plasma TVs, while using signals to be generally employed in
product design, we determined the operating power by taking the mean of power
consumptions of these signals plus those of color bar signals and three-stripe
signals, in order to bring measurement result closer to actual use.

(2) Ps: standby power (W)The standby power shall be the mean of power consumption of when power isturned off by main power (Ps1) and that of when power is turned off by a remotecontroller while the main power remains on (Ps2). Note, however, that in thecase that a power switch is only controlled by either a main power or a remotecontroller, the standby power shall be the power consumption of when the powerswitch is turned off.
PS = (PS1 + P S2) / 2(3) PA: reduced power consumption by energy-saving function (W)Reduced power consumption by energy-saving function shall be the larger
value (either PA 1 or PA2), when color bar signal is used as video signal.
(a) PA1: reduced power consumption by the function which automatically controls

58video images according to ambient illuminance (hereinafter referred to as“automatic brightness adjustment function”) (W)The reduced power consumption by the automatic brightness
adjustment function shall be a numeric value to be obtained by subtracting a
power consumption value of when the ambient illuminance is 0 lux (PA1Min)
from the smaller of power consumption values of either when the ambient
illuminance is 300 luxes or higher or when the power saving function isswitched off (PA1Max).
PA1 = PA1Max - PA1Min(b) PA2: reduced power consumption by an energy-saving switch (W)The reduced power consumption by an energy-saving switch shall be a
numeric value obtained by subtracting a power consumption value of whenthe energy-saving switch is turned on (PA2Min) from a power consumption
value of when the energy-saving swtich is turned off (PA2Max).
PA2 = PA2Max - PA2Min(4) Condition for Measurements
Except for the cases listed below, power consumption measurements of (1) to(3) mentioned above shall take place under the conditions specified by “General
Condition” of the Japan Industrial Standard C6101-1, 3.1.
(a) For (1) and (2), the contrast control of televisions shall be set so that power
consumption of when receiving flat level white signals will be maximized.
For (3), it shall be set to a factory default.

In addition, the brightness

control shall be set to a factory default.
On the other hand, the contrast, brightness and backlight controls for LCD
TVs and the contrast and brightness controls for plasma TVs shall be set tothe standard setting (which is recommended by manufacturers and to be
used at general households).
(b) Audio output of television shall be set to the default specified in“Measuremment Method”, the Japan Industrial Standard C6101-1, 4.2.1.
(c) Satellite dish, additive functions and others which can be arbitrarily turned
ON/OFF shall be turned OFF.
(d) Measurement should take place only when a TV set is in stable condition,even in the period of switching test signals.

However, in the case of plasmaTVs, the measurement should take place before burn-in protecting function is59

activated.
(5) Input Signals
When measuring power consumption described in (1) to (3) above, signal
input shall conform to the followings.
(a) Measurement through input of a terrestrial wave band signal (analog ordigital) or a baseband signal
a. A flat level white signal, flat level black signal, color bar (75/0/75/0) signal
and three-vertical-stripe signal specified in “Test Video Signal”, the Japan
Industrial Standard C6101-1, 3.2.1 shall be used as a video signal.
b. An audio signal shall be a 1kHz sinusoidal signal.
c. A high frequency wave television signal specified in C6101-1, 3.3, of thesame standard shall be used as an analog input signal.
d. As for the level of digital input signals, signals that conform to the standardtransmission method of the digital and high-definition broadcastings which
are of standard television broadcasting by broadcasting stations shall be
used as an input signal. The level of the input signal shall be -49 dB(mW).
(b) Measurement through input of a satellite broadcasting wave band signal(analog or digital)a. A flat level white signal, flat level black signal, color bar (75/0/75/0) signal
and three-vertical-stripe signal specified in “Test Video Signal”, the Japan
Industrial Standard C6101-1, 3.2.1 shall be used as a video signal.
b. An audio signal shall be a 1kHz sinusoidal signal, and the modulation
factor of PCM modulation shall be set to -18dB of the peak modulation.
c. The signals converted to the first intermediate frequency band that
conform to the standard transmission method of the standard andhigh-definition television broadcasting by the satellite broadcastingstations shall be used as an analog input signal.

The level of the input

signal shall be –45 dB (mW).
d. The signals converted to the first intermediate frequency band that
conform to the standard transmission method of digital broadcasting which
is of the standard and high-definition television broadcasting, ultrashortwave broadcasting, and data broadcasting within the frequency band rageof 11.7 to 12.2 GHz by the satellite broadcasting stations shall be used as60

an input signal.

The level of the input signal shall be -45dB (mW).

Target Scope of Video Cassette Recorders
The criteria shall apply to VCR (Video Cassette Recorders) or DVD recordersthat are utilized by AC electric circuits (rated frequency of 50 or 60 Hz, rated voltage of100V).

However, the followings shall be excluded from the target scope.

1. VCR or DVD Recorders for Industrial Use
They are the models for industrial purposes, such as the ones forbroadcasting whose picture input/output form is RGB or component output, whose
video

input/output

terminals

are

BNC

terminals,

and

whose

externalsynchronization terminal is input/output terminals for synchronized signals, or
any others of special specifications.

They shall be excluded because they have

limitations in the specifications and because their volume is still modest.
2. VCR or DVD Recorders With Extremely Low Market Share- VCR with a built-in high-vision decoder(Volume of shipments in 2003: 16,855 sets)- DVD recorders with no VCR nor HDD(Volume of shipment in 2003: 286,416 sets)- Those with game or server function(Volume of shipment in 2003: 181,723 sets, the number of models: 2 types)- Those with digital tuner(Volume of shipment in 2004: 144,000 sets, the number of models: 6 types)
Consumer needs have not yet been defined for the equipment listed above
that, in general, have a few models available in the market.

Depending on future

developments, however, we shall conduct a necessary review when it is consideredappropriate to include them in the scope.
Note 1:

Hard disk recorders shall be excluded, because both the market share andthe number of models available in the market are low. However, those witha DVD recorder shall be included in the scope.

Target Fiscal Year and Others for Video Cassette Recorders, etc.
1.

In general, a considerable improvement in energy consumption efficiency of
VCR, etc. is made when a model change takes place, and a typical development
period of these new products is approximately 2 years.

For this reason,

consideration should be given so that the manufacturers can take at least twoopportunities of bringing out new models before the next target fiscal year.
On the other hand, in light of measures against global warning, in order toensure that products that achieved the target standard value become widely usedamong consumers during the first commitment period of Kyoto Protocol (2008 to
2012), it would be desirable to achieve the target in as short time as possible,
assuming that the tenure of use of VCR, etc. would be approximately 10 years.
With the above in mind, the target fiscal year of DVD recorders (limited tothose with either VCR or HDD), which are newly added to the target, shall be set
to 2008; that is three years after establishment of the criteria.
In addition, the target fiscal year for VCRs that have already been covered in
the target scope shall be the same as at present (fiscal year 2003 and each year
after).
2.

In addition, the improvement rate of energy consumption efficiency in thetarget fiscal year (excluding VCR) is expected to be approximately 22.4% based on
the assumption that there will be no change from the current volume of shipment
or compositions in each category (the resut in 2004 and prospect partially
included).

<Overview of Estimation (only for DVD recorders)>(1)

Energy consumption efficiency estimated from values of actual achievementsof DVD recorders shipped in 2004: 66.0 kWh/year(2)

Energy consumption efficiency estimated from the target standard values of
DVD recorders to be shipped in the target fiscal year: 51.2 kWh/year(3)

Improvement ratio of energy consumption efficiency(66.0 - 51.2)

Classification of VCR, etc.
I.

Basic Idea
VCR were designated as specified equipment for the Top Runner Standard in

1999.

However, since then, with the rise of new types of recording devices such as

DVD recorders, etc., the volume of shipments of VCR has dramatically dropped (SeeFigure 1).
We shall continuously utilize the present classifications for VCR, because thevolume of shipment is expected to remain decreasing in the future, and because there
has been no such significant change which requires the modification of theconventional indicators used in the classifications.
DVD recorders can be roughly divided into (a) those having HDD only, (b) thosehaving VCR only, and (c) those having both HDD and VCR, by availability of theattached recording device. As these attached recording devices differently influenceenergy consumption efficiency (annual energy consumption, the same hereinafter) anddevelopment of energy saving technologies in the future, DVD recorders shall beclassified by the attached recording devices.

In addition, with the increasing storage

capacity and advancing digitalization, most of DVD recorders have multiple tuners,
encoders, terminals as well as digital networking terminals for input/output of digital
signals and for exchange of digital control signals, in order to enable simultaneousrecording.

Since these features also influence energy consumption efficiency andfuture technological development, DVD recorders shall be classified by availability ofthem as well.

Specific Classification Method

1. VCRAs we stated earlier, the classifications for VCR shall remain unchanged.
(a) VCRs with signal processing power for 400 or more lines of horizontal
resolution that have satellite broadcasting receiving functions(b) VCRs with signal processing power for 400 or more lines of horizontal
resolution that do not have satellite broadcasting receiving functions(c) VCRs without signal processing power for 400 or more lines of horizontal
resolution that have satellite broadcasting receiving functions(d) VCRs without signal processing power for 400 or more lines of horizontal
resolution that do not have satellite broadcasting receiving functions
2. DVD Recorders
DVD recorders can be roughly divided into (a) those having HDD only, (b) thosehaving VCR only, and (c) those having both HDD and VCR, by availability of theattached recording device. As these attached recording devices differently influenceenergy consumption efficiency (annual energy consumption, the same hereinafter) anddevelopment of energy saving technologies in the future, DVD recorders shall beclassified by the attached recording devices. In addition, with the increasing memory
capacity and advancing digitalization, most of DVD recorders have multiple tuners,
encoders, terminals as well as digital networking terminals for input/output of digital68signals and for exchange of digital control signals, in order to enable simultaneousrecording.

Since these features also influence energy consumption efficiency andfuture technological development, DVD recorders shall be classified by availability ofthem as well.
(1) Classification by Availability of Attached Recording Device
DVD recorders can be roughly divided into (a) those with HDD only, (b) thosewith VCR only, and (c) those with boh HDD and VCR, by availability of theattached recording device.

As these attached recording devices differently

influence energy consumption efficiency and development of energy saving
technologies in the future, DVD recorders shall be classified by them.
Note that “DVD recorders with HDD only” refers to a type of DVD recorders
which is additionally equipped with HDD as a memory device, and which cantemporarily record the vast amount of images in HDD and copy them to DVD asnecessary. “DVD recorders with VCR only” refers to a DVD recorder integrated
with VCR, which can function as both DVD recorder and VCR in one housing.
“DVD recorders with both HDD and VCR” refers to a DVD recorder integrated
with HDD and VCR, which can function as both DVD recorder with built-in HDD
and VCR in one housing.
Proposal for Classification(a) DVD recorders with HDD only(b) DVD recorders with VCR only(c) DVD recorders with both HDD and VCR(2) Classification by Number of Tuners and Signal Conversion Functions
The DVD recorders now on the market have at least one each of a terrestrial
broadcasting analog tuner and an MPEG encoder (converting an analog signal intoa digital signal of MPEG format), in order to achieve its basic functions. Like
VCRs, in order to expand the choice of programs to record, some DVD recorders areequipped with multiple tuners, such as terrestrial broadcasting analog tuners andsatellite broadcasting tuners.

Furthermore, some of those with HDD andmultiple tuners are equipped with an additional MPEG encoder for simultaneousrecording of multiple broadcasting signals.

Since these features influence energy

consumption efficiency, DVD recorders shall be classified by them.

Note, however,that additional MPEG encoders shall be classified separately, because they are69

incorporated after equipment of multiple tuners, and because increased power
differs between when a MPEG encoder is added and when a tuner is added (when atuner added: approx. 8W, and when a MPEG encoder added: approx. 6W).

The

term “basic specifications” used herein shall be defined as “those having one eachof terrestrial broadcasting analog tuner and MPEG encoder”.

“Those having

multiple tuners” refer to those having more than one tuner, but those having
multiple MPEG encoders shall be excluded.

“Those having multiple MPEG

encoders” refers to those having more than one MPEG encoder.
For DVD recorders with VCR only, there is no necessity to add an MPEG
decoder because these DVD recorders cannot record multiple digital signals
simultaneously.

Thus, they shall not be classified by availability of MPEG

encoder.
Proposal for Classification(a) DVD recorders of basic specification(b) DVD recorders having multiple tuners (excluding those having multiple MPEG
encoders)(c) DVD recorders having multiple MPEG encoders(3) Classification by Availability of Digital Network Terminals
With advancing digitalization, various digital-supporting terminals havebeen developed.

As addition of them has an impact on energy consumption

efficiency, DVD recorders shall be classified by the availability of them.
Proposal for Classification(a) DVD recorders without digital network terminals(b) DVD recroders with digital network terminals* ”Digital network terminal” refers to i) iLink, ii) USB, iii) LAN, and iv) HDMI.
i)iLink: another name of “IEEE 1394” standard that is one of the transmission methods
connecting a PC and imaging equipment with peripheral devices, and it is expected to be
the general standard.

At the same time, there is a move to utilize it in LAN for homes.

Examples include an external output terminal of a digital video camera (commonly known
as “DV terminal”).
ii)

USB (Universal Serial Bus): it is one of the standards for a data transmission channel
connecting peripheral devices such as a keyboard, mouse, modem, joystick, etc. with70

personal computers, etc.
iii) LAN (Local Area Network): A network of computers, imaging equipment, and printers inthe same building and connected by pair cables, fiber-optica cables, etc. with the purposeof data exchange.

There are some variations depending on connection form andcommunication control method, yet Ethernet standard is the most prevalent.
iv) HDMI (High-Definition Multimedia Interface): A new standard of digital video/audio
input/output interface, mainly for home appliances and AV equipment.

Since

video/audio/control signals can be transmitted/received through 1 cable, it will allow tocontrol multiple AV devices with one remote-controller.

Target Standard Values for Video Cassette Recorders, etc.
I.

Idea on Establishment of Target Standard Values

1. Basic Idea
We shall set target standard values based on the idea of Top Runner Method.
The specific policy shall be as follows:(a) Target standard values should be set for every category that has been
appropriately defined.
(b) As for the categories where future technological advances are expected to
improve efficiency, the target standard values should allow for the
improvement as much as possible.
(c) Target standard values should not conflict among categories.
2. Flow of Setting Target Standard Values(1) VCRs
Video cassette recorders (VCRs) were designated as specified equipmentof Top Runner Standard in 1999.

However, with the rise of new types ofrecording devices such as DVD recorders, the volume of shipment of VCRs is
expected to drop rapidly in the near future.

In addition, considering thesituation where various manufacturers are focusing their efforts fortechnological development on the other recording devices, further improvementin efficiency is hardly expected for VCRs, since there will be no room fortechnological development of VCRs.
In light of the above, we decided to leave the target standard values for
VCRs unchanged (See III).
(2) DVD Recorders
Among DVD recorders, annual energy consumption of “DVD recorders
with HDD only” and “DVD recorders with both HDD and VCR” has a positive
correlation with storage capacity of HDD (See Figure 1). Thus, in a given
category, if we simply set a value of a model with less annual enrgy
consumption as a target standard value (annual energy consumption), it is73

more likely that models with larger HDD storage capacity may no longer be
produced. With the above in mind, we shall express target standard values(annual energy consumption) by a linear function formula (calculation formula)with the HDD storage capacity as a variable.
Since “DVD recorders with VCR only” do not incorporate an HDD, weshall express their target standard values (annual energy consumption) by anumerical value of the annual energy consumption.
We established specific target standard values as described below.
(a) “DVD recorders with HDD only” and “DVD Recorders with HDD and VCR”
First of all, with certain number of data, we found a correlation slope
between storage capacity of HDD and annual energy consumption for “DVDrecorders with HDD only” of basic specification (one terrestrial analog tuner
and one MPEG encoder), from which a relationship of the HDD capacity andannual energy consumption can be extracted as strictly as possible.

As thisresulted in the slope of 0.02 (kWh/GB), we decided to uniformly use the slope of
0.02 (kWh/GB) for all categories of those with HDD (including “DVD recorders
with boyh HDD and VCR”).

Then, under the slope, the calculation formula isset for each category so that the intercept will be a minimum. Finally, in theconsideration of improvement in efficiency by the target fiscal year, acalculation formula obtained by translating the above calculation formuladownward shall be set for the target standard value.
(b) “DVD recorders with VCR only”
For each of those with or without a digital network terminal, the smallest
numeric value of annual energy consumption shall be a Top Runner Value.
Then, an improvement in efficiency by the target fiscal year will be added tothe above smallest annual energy consumption, and it shall become a target
standard value.
3. Handling Categories in Which No Models Presently Exists
Although we decided to classify DVD recorders by the availability of multiple
tuners/MPEG encoders or digital network terminals, some categories (Category F,
K, L, O, and P) presently have no models; therefore, we cannot set the target
standard values based on actual measurements.

On the other hand, due toadvancing digitalization in the future, the number of models is expected toincrease in these categories.

Thus, in order to set the target standard values for74

these categories, we first determined an additional value due to incorporation ofdigital network terminals as well as that due to addition of built-in tuners or
MPEG encoders. Then, we set the Top Runner Values by adding or subtracting
them to numeric target standard values of categories in which models exist.
When calculating the additional value attributed to addition of tuners, we
calculated the difference of Top Runner Values between a pair of those without
terminals and the difference of Top Runner Values between a pair of those withterminals (difference between Category A and C: 17 kWh, difference between
Category B and D: 11 kWh), and we adopted the lower value (i.e., 11 kWh).

Tocalculate the additional value attributed to addition of MPEG encoders, as only
those without terminals are actually existing, we adopted the difference of Top
Runner Values between them (difference between Category A and E: 19 kWh).
In addition, for the digital network terminals, we used the difference of Top
Runner Values between those with terminals and without terminals among “DVDrecorders with HDD only” of the basic specification (the difference between
Category A and B of 5 kWh), which has the largest number of models.
Further, for any categories in which models currently exist, intending toencourage more energy saving efforts (setting stricter standard values), we
compared the values plus the additional values with actual measurements, andadopted the smaller of them as a Top Runner Value.
II. Room for Improvement in Energy Consumption Efficiency Through Technological
Advance in the Future
Technological development for DVD recorders has been carried out, mainly for
improvement of user convenience.

Overall, technological development towards

higher energy consumption efficiency have just begun, although it depends on a
manufacturer.

In other words, a room for improvement in efficiency still remains for

DVD recorders.
DVD recorders are expected to raise the efficiency through power saving efforts
of an LSI (Large Scale Integration) or HDD (hard disk), or CPU (Central ProcessingUnit). Taking into our consideration such possible improvement in efficiency andefforts toward energy saving, we set the target standard value by 5% up from thecurrent Top Runner Value.

75III. Specific Target Standard Values(1) VCR
We left the target standard values of VCR unchanged as we discussed in“I”, 2.
(2) DVD Recorders(a) “DVD Recorders with HDD Only” (Category A to F)
For those having the basic specification in the categories in which models
exist(Category A and B), under the correlation slope of HDD storage capacity
and annual energy consumption determined in “I”, 2, (2), we determined thecalculation formula of the Top Runner Value by adapting the intercept to theone having the lowest annual power consumption for each category (See Figure
3 and 4).
For other categories in which models exist (Category C, D, and E), withthe same slope in the above, we first determined the calculation formula of the
Top Runner Value by adapting the intercept to the one having the lowest
annual energy consumption for each category.

At the same time, we also

determined the Top Runner calculation formula by adding the additional
values determined in “I” to the values of those having the basic specification.
Then, comparing these formulas, we decided to adopt the calculation formulaexpressing less annual energy consumption (more energy-saving) (See Figure 5to 7).
For the categories in which no model exists (Category F), as we could not
make actual measurement, we worked out the calculation formula by adding
the additional values determined in “I”, 3 to the calculation formula for the
categories in which models exist (See Figure 7).
After going through the process described above, we determined thetarget standard values by adding the efficiency of improvement of 5% to thecalculation formula of the Top RunnerValues.
(b) “DVD Recorders with VCR only” (Category G to J)
First, for each category, we determined a numeric value of the one withthe lowest annual energy consumption as the Top Runner value. At the sametime, we also determined the numeric Top Runner Value calculated by adding
the additional values determined in “I”, 3 to the values of those having thebasic specification. Then, comparing these values, we decided to adopt the76

numeric

value

expressing

lessannualenergyconsumption(moreenergy-saving).
Then, we determined the target standard values by adding 5%
improvement in efficiency to the Top Runner Values.
Now, the target standard value for DVD recorders of basic specification
and with no digital network terminal (E=46) is higher than that for thosehaving multiple tuners but no digital network terminal (E=39) (inverse
correlation).

Thus, we used the value of the latter.

(c) “DVD Recorders with HDD and VCR” (Category K to P)
For the category of DVD recorders having multiple tuners but no digital
network terminals where models actually exist (Category M), we worked out
the calculation formula of the Top Runner Value by adapting to those with thelowest annual energy consumption, under the correlation slope of between
HDD storage capacity and annual energy consumption determined in “I”, 2., (2)(See Figure 8).
For the category of DVD having multiple tuners and digital network
terminals where models actually exist (Category N), using the same slope as
the above, we determined the Top Runner calculation formula by adapting tothose with the lowest annual energy consumption.

At the same time, we also

determined the Top Runner calculation formula by adding the additional
values determined in “I”, 3 to the values for those having multiple tuners but
no digital network terminal (Category M). Then, comparing these formulae,
we decided to adopt the calculation formula expressing less annual energy
consumption (more energy-saving) (See Figure 9).
For the categories in which no model exists (Category K, L, O and P), as
we could not make actual measurement, we found the calculation formula byadding or subtracting the additional values to or from the Top Runner
calculation formulae for Category M and N (See Figure 7).
Then, we determined the target standard values by adding 5%
improvement in efficiency to the Top Runner Values.

Energy Consumption Efficiency of VCR and DVD Recorders and Method of
Measurement
1. Basic Idea
As for Video Cassette Recorders (VCR), when they were designated as specified
equipment of the Top Runner Standard in 1999, “Standby Power Consumption” wasintroduced as a realistic indicator on energy consumption efficiency. As far as VCRs
are concerned, when making a review this time, we took into consideration thefollowing: (a) no new specification that may have impact on the actual status of theusage has been added, (b) there has been no particular change in the amount of TV
watching time, (c) the volume of shipment of video tapes is on a downward trend, etc.
It is unlikely that the operating time of VCRs increase than before, and we believe thatthey are still mainly in standby state.

Hence, it would be reasonable to adopt thestandby power and the existing method of measurement, which have been
conventionally used.
In addition, for DVD recorders, as the operating power accounts for more of thetotal power consumption, contrary to the case of VCR, we adopted annual power
consumption as their energy consumption efficiency and specified a new method of
measurement.
2. Specific Energy Consumption Efficiency and Measuring Method(1) VTRa) Method of Measuring Energy Consumption Efficiency
The energy consumption efficiency shall be standby power, and shall be a
numeric value in Watt obtained by the following method and calculated to one
place of decimals.
(a) Measurement shall take place under the condition, where the AC poweris supplied, VCR is turned off, and remote control operation is ready(hereinafter referred to “standby state”).
(b) For models with display function (such as of clock) that can be selected
to be display/non-display, the energy consumption efficiency shall becalculated with the following expression:
P = Pdon - (Pdon - Pdoff) × 0.2

85

P:

standby power (Watts)

Pdon: standby power during display state (Watts)
Pdoff: standby power during non-display state (Watts)(c) In the case of that power is supplied to any device other than a main
body of VCR, it shall not be included in the standby power.
b) Conditions of Measurement(a) The acceptable variation of AC power supply shall be: voltage of 100(V)± 2 (%), and frequency of 50 or 60 (Hz) ±1 (Hz).

(b) If a display unit (such as of clock) has light/dark switching function, it
shall be set to a factory default.

In addition, the clock shall be set to“10:00”.
(c) Measurement should take place only when power consumption of arecorder is in adequately stable condition.
(d) A wattmeter to be used for measuring power consumption shall beequipped with averaging measurements function, shall be capable ofmeasuring a waveform with the power peak factor up to 3, and shall becalibrated so that the accuracy falls within 1%.
(2) DVD Recordersa) Method of Measuring Energy Consumption Efficiency
The operational power is greater than VCRs, and addition of new features
is expected to extend the operating time as well.

Thus, energy consumption

efficiency shall be annual energy consumption comprised of not only standby
power but also operational power, and it will be measured by the following
method.

Concept of Setting DVD Recorder Operating Time Based on
the Survey of Actual Status of the Usage
Since DVD recorders are evaluated in terms of annual energy consumption
including annual operational power as well as annual standby power, we need to set
operating time for every action, such as recording/playing.

In this section, we shallset the annual standard operating time based on the survey result of actual status of
the usage.
1. DVD Recorders with HDD Only
(1) Survey result on actual status of the usage(a) HDD recording time: 1.88 hours/day(b) HDD playing time: 1.20 hours/day(c) DVD recording time: 0.33 hour/day(d) DVD playing time: 0.05 hour/day(e) Copying time (HDD Ù DVD): 0.2 hours/day(2) The time listed in (1) above shall be rounded off in 0.5-hour uniti)

3. DVD Recorders with both HDD and VCR
We could not obtain reliable data for those with both HDD and VCR, because
there are only a few users at present.

However, taking into consideration that use of

VCR is on a decline for DVD and HDD functions, and that use of VCR function istransient, it can be assumed that actual status of the useage of DVD recorders withboth HDD and VCR will not be significantly different from the status of DVD recorders
with HDD only.

Accrodingly, the same operating time as in 1. for DVD recorders with

HDD only was also applied to DVD recordes with both HDD and VCR.
