FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 62087-2 has been prepared by technical area 19: Environmental and energy aspects for
multimedia systems and equipment, of IEC technical committee 100: Audio, video and
multimedia systems and equipment. It is an International Standard.

INTRODUCTION
This document identifies test signals to be used to determine power consumption and related
characteristics specified in some other parts of the IEC 62087 series.
IEC 62087:2008 (second edition) added methods for measuring On (average) mode power
consumption of television sets, based on three video signal sets. These include static signals,
dynamic broadcast content signals, and Internet content signals.
IEC 62087:2011 (third edition) revised methods for measuring power consumption of set-top
boxes. The signals and media were not changed in this third edition.
IEC 62087-2:2015 (first edition) separates signals and media that are to be used for
determining power consumption and related characteristics into a dedicated part. The three
original video signal sets (static, dynamic broadcast-content, and Internet-content) are not
changed. This edition adds signals for the purpose of determining the peak luminance ratio that
is sometimes associated with television set power consumption measurement programs.
This second edition of IEC 62087-2 adds HDR and UHD video test signals and dynamic box
and outline test signals for TV power consumption testing. All test signals are available from a
specified IEC online repository for download, replacing the former physical media distribution.
IEC 62087 series currently consists of the following published parts:
– Part 1: General
– Part 2: Signals and media
– Part 3: Television sets
– Part 4: Video recording equipment
– Part 5: Set-top boxes

average picture level based on non-linear input signal
APL′
average level of all pixels of a single video signal frame or a group thereof in the non-linear
luminance domain
EXAMPLE Display equipment such as television sets or computer monitor receive input signals that encode
luminance or brightness in a non-linear way. Examples for such non-linear encoding are PQ (absolute luminance) or
HLG (brightness) EOTFs (ITU-R BT.2100-2).
Note 1 to entry: APL′ is defined as a percentage of the range between reference black and reference white level.
Note 2 to entry: This is not a measure of the linear signal that might be available inside of some display equipment
and delivered to the display device. The properties and their differences of the external and internal video signals
are shown in Figure 1.
Figure 1 – Occurrence of linear and non-linear signal encodings in context
of a typical display processing pipeline for computing APL and APL'
3.1.9
hybrid log-gamma
HLG
one set of transfer functions offering a degree of backwards compatibility by more closely
matching the previously established television transfer curves
Note 1 to entry: Sets of transfer functions related to HDR signals are specified in Rec. ITU-R BT.2100-2.
Note 2 to entry: HLG is used both as a description of a dedicated transfer function and as a video format name.
3.1.10
high dynamic range video
HDR video
capability of components in a video pipeline to capture, process, transport or display luminance
levels and tone gradations that exceed capabilities of conventional SDR imaging pipelines
components
EXAMPLE An HDR video signal typically uses a greater bit depth, luminance and colour volume than standard
dynamic range (SDR) video. It also typically utilizes different tone curves such as perceptual quantizer (PQ) or hybrid
log gamma (HLG) as specified in ITU-R BT.2100 instead of gamma, as used with SDR. When the HDR video signal
is rendered on an HDR display, it is possible to see greater luminance ranges and wider colour gamut
Note 1 to entry: HDR video can provide an enhanced viewer experience and can more accurately reproduce scenes
that include, within the same image, deep dark areas, and bright highlights, such as emissive light sources and
reflections.

bar signal for NTSC defined in IEC 60107-1:1997, 3.2.1.2 shall be used and shall cover the full
field of the display. Reference to the signal online repository is provided in 5.1 and Annex A.
NOTE The 50 Hz signal has eight bars (including black), and the 60 Hz signal has seven bars (white, yellow, cyan,
green, magenta, red and blue, in this order).
4.1.2.5 Three-bar video signal
The active picture area of the signal shall be three bars of white (100 %) over a black (0 %)
background as defined in IEC 60107-1:1997, 3.2.1.3. This is an SDR signal. Reference to the
signal online repository is provided in 5.1 and Annex A.
4.1.3 Dynamic broadcast-content video signal
4.1.3.1 General
The media includes dynamic broadcast-content video signals in different progressive scan
formats, resolutions, and dynamic ranges; see Table 2. Additional information is available in
Clause A.2.

4.1.3.2 Standard dynamic range dynamic video signals
For the generations of CRT, early TFT (with 'always on' backlight) and plasma-based displays,
generally very little difference between the display capabilities amongst TVs was assumed and
the SDR signal specifications of, for example, ITU-R BT.709 and BT.1886 were deemed
sufficient for content delivery, and consequently for power consumption measurement of
television sets. For SDR-only capable television sets, suitable SDR test media are available in
appropriate resolutions and progressive scan formats. The duration of the SDR audio-visual
signal is 10 min.
The standard dynamic range dynamic video signals shall be downloaded from the specified IEC
online repository; see 5.1 and Annex A.
4.1.3.3 High dynamic range dynamic video signals
High dynamic range (HDR) video has gained increasing importance throughout the entire video
ecosystem from capture, production and processing, through to distribution and presentation.
HDR television sets potentially have higher peak luminance level capabilities in comparison to
SDR TVs or SDR TV modes. For HDR-capable television sets, suitable HDR test media are
available in appropriate codecs, resolutions, and progressive scan formats. All HDR video
signals in HDR10 format contain static metadata. The duration of the HDR audio-visual signal
in both HLG and HDR10 formats is 5 min.
The high dynamic range dynamic video signals shall be downloaded from the specified IEC
online repository; see 5.1 and Annex A.
4.1.4 Internet-content video signal
The media includes an Internet-content video signal. This is an SDR signal. Reference to the
signal online repository is provided in 5.1 and Annex A.
Additional information is available in Clause B.4.
4.1.5 Audio signal associated with video signals
Sine-wave signals at a frequency of 1 kHz or, if 1 kHz cannot be used, signals at the centre
frequency of the transfer range specified by the manufacturer of the UUT shall be used. For
digital inputs, the level of the signal shall be 18 dB below full scale. For analogue inputs, the
signal shall be 20 dB below the reference level or greater with a suggested signal level of
500 mV RMS.
The video signals described in 4.1.2, 4.1.3, and 4.1.4 are encoded with an accompanying 1 kHz
tone with a level of 18 dB below full scale.

4.2 Video signals used for the determination of the peak luminance ratio
4.2.1 General
The use of signals defined in 4.2.2 shall be limited to determining the peak luminance ratio
between SDR picture settings and should not be used for determining absolute screen
luminance.
NOTE 1 Such luminance comparisons are sometimes associated with TV energy efficiency programmes.
NOTE 2 For more information about choosing the signal for determining the peak luminance ratio, see Annex C.
4.2.2 Video signals
4.2.2.1 Three-bar video signal
The three-bar video signal is specified in 4.1.2.5. This is an SDR signal. Reference to the signal
online repository is provided in 5.1 and Annex A.
4.2.2.2 Dynamic box and outline video signals
The set of two box and outline dynamic video signals includes a white (100 %) rectangle on a
grey (34 %) background, with a black (0 %) border near the outer part of the picture. This border
includes a moving pattern comprising black (0 %) and white (100 %) segments. Each corner
contains a 1 % coverage full-field colour bar pattern. The dimensions of the central white
(100 %) rectangle of the two signals correspond to the defined L20 and L40 static test patterns
[IDMS v1.1a, Appendix A12]. The signal with the corresponding larger white rectangle may be
used when measuring smaller screens in order to provide sufficient white coverage as required
by screen luminance contact probes. An example of L20PeakLumMotion is shown in Figure 2.

Figure 2 – Dynamic box and outline video signal (L20PeakLumMotion)
The two dynamic video signals as listed in Table 3 below are in SDR, rendered in SD, HD and
UHD formats and are available in 50Hz (50p) and 59,94Hz (5994p). The selection of signal
format shall be based on the one which most closely resembles the highest supported screen
resolution of the UUT. The central white area in L40PeakLumMotion is greater than that in
L20PeakLumMotion. Reference to the signal online repository is provided in 5.1 and Annex A.
