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.
International Standard IEC 62087-2 has been prepared by technical area 12: AV energy
efficiency and smart grid applications, of IEC technical committee 100: Audio, video and
multimedia systems and equipment.
This first edition of IEC 62087-2 together with IEC 62087-1 and IEC 62087-3 to IEC 62087-6
cancels and replaces IEC 62087:2011 in its entirety. This edition constitutes a technical
revision.
This edition includes the following significant technical changes with respect to Clause 11 of
IEC 62087:2011.

on the subclause numbers within the text of the television test method.
– Video test patterns used to determine the peak luminance ratio are now included on the
discs.
– Audio test signals are specified.

– The box and outline video signal has been added.
The text of this standard is based on the following documents:

INTRODUCTION
This standard identifies signals and media to be used to determine power consumption and
related characteristics specified in some other parts of IEC 62087:2015. The media include
Blu-ray Discs™ and DVDs.
IEC 62087:2008 (second edition) added methods for measuring On (average) mode power
consumption of televisions, based on three video signal sets. These include static, dynamic
broadcast-content, 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.
This edition of IEC 62087 separates the standard into parts, including this signals and media
part which specifies signals that are to be used for determining power consumption and
related characteristics. 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 power
consumption measurement programs.
IEC 62087 has been subdivided and currently consists of the following planned or published
parts:
– Part 1: General
– Part 2: Signals and media
– Part 3: Television sets

4.3 Audio signals used for determination of audio power consumption
4.3.1 Audio signals
4.3.1.1 Sine wave signal
The signal shall be a sine-wave at a frequency of 1 kHz or, if 1 kHz cannot be used, the sine
wave frequency shall be at the centre of the frequency range specified by the manufacturer.
4.3.1.2 Simulated programme signal
A simulated programme signal shall have a mean power spectral density that closely
resembles the average of mean power spectral densities of a wide range of programme
material, according to IEC 60268-1.
Such a signal may be obtained from pink noise, band-limited by a filter whose response
conforms to that given in IEC 60268-1. The crest factor of a noise source should fall between
3 and 4 to avoid clipping of amplifiers.
The simulated programme signal is not included in the media supplied in Clause 5.
4.3.2 Signal levels
4.3.2.1 Audio signal level, analogue
For baseband analogue inputs, the input signal shall be at a level of 500 mV rms, according to
the rated source e.m.f of IEC 61938.
4.3.2.2 Audio signal level, digital
For digital inputs, the input signal shall be at a level of 12 dB below reference full scale,
according to IEC 61938, IEC 60958-1 and IEC 60958-3.
4.3.2.3 Audio signal level, RF
For FM radio tuners, the input signal shall be at an aerial input terminal at a level of 40 dB
(pW). The modulation factor shall be 54 %, according to IEC 61938.
For AM radio tuners, the input signal shall be at an aerial input terminal with an induced
electromagnetic field (e.m.f.) of 1 mV. The modulation factor shall be 30 %, according to
IEC 61938.
In the case of non-detachable aerial antennas the RF signal level for FM and AM radio tuners
shall be high enough to reproduce a noise-free audio signal.
For DAB and DAB+ the OOI point is sharply defined as the receiver C/N (carrer to noise ratio)
degrades and BER increases, so this may be used as a means to assess the signal
requirement of the receiver. The OOI method may be implemented so that it is equivalent to a
–4
BER of 10 . The method involves monitoring (by a human observer or if available, automated
equipment) of an encoded 1 kHz audio sinewave from the audio output source (speaker,
headphone, etc) and setting the RF signal level where the onset of audio defects (dropouts,
burbles, “chirps”, etc.) can just be heard in the sinewave in a 10 second listening period. This
RF level is the OOI threshold for sensitivity.
In the case of a non-detachable aerial antenna the RF signal level shall be high enough to
reproduce an audibly defect-free audio signal for DAB and DAB+.
NOTE ETSI EN 300 401, Clause 7 and ETSI TS 102 563 provide additional information about DAB and DAB+.

6 Signal generation
6.1 Audio-visual signal generating equipment
The audio-visual signal generating equipment used during the test shall be capable of playing
the media specified in this standard and shall be calibrated to conform with the accuracy
required in 6.3. Depending on the input terminals used during the measuring procedure, the
audio-visual signal generating devices shall provide the signals as specified in 6.2.
If connecting a particular model of audio-visual signal generating equipment to the UUT
causes any settings of the UUT to change, an alternate model shall be used during the
measuring procedure.
Some video sources with HDMI outputs have been shown to lead to anomalous television
power consumption readings. Two possible causes have been identified: miscommunication
between source and sink, and proprietary communications between source and sink.
To reduce the possibility of miscommunication, multiple models of signal generating
equipment may be connected and a spot check of the power consumption may be performed
with a static image. A model of signal generating equipment that produces anomalous results
should not be used.
To reduce the likelihood of unwanted proprietary communications, signal generating
equipment from a different manufacturer than that of the UUT should be used.

Annex A
(informative)
Description of video signals used for
the determination of power consumption
A.1 General
Power consumption of some equipment, such as television sets, may vary depending on the
APL′ of the displayed images.
Three video signals are available. These include:
– static video signals (4.1.2);
– dynamic broadcast-content video signals (4.1.3);
– Internet-content video signals (4.1.4).
Either the static video signals or the dynamic broadcast-content video signals are intended to
be used when determining power consumption of equipment that typically uses broadcast-
type video content, such as television sets. The Internet-content video signal is intended to
emulate static, non-video content from the Internet.
NOTE The Internet-content video signal is not intended to emulate dynamic video material that is often
downloaded or streamed from the Internet. Dynamic video is best represented by the dynamic broadcast-content
video signal specified in 4.1.3.
A.2 Static video signals
The static video signal method was initially developed by JEITA in Japan for determining
television power consumption.
Measurement of power consumption based on the static video signals might be chosen for the
simplicity of the test. The static signals may also be appropriate for use with equipment that
typically does not have a video input or is typically not capable of playing video streams.
Power consumption measurements using static signals can often be performed directly by
means of a wattmeter.
A.3 Dynamic broadcast-content video signals
The APL′ of the dynamic broadcast-content video signal was chosen to best emulate actual
APL′ determined internationally. During development of IEC 62087:2008, the project members
measured at least 40 h of typical broadcast content, including a variety of genres from a
variety of broadcast stations in Australia, Japan, the Netherlands, the United Kingdom and the
United States. The captured APL′ curves were averaged to create a target APL′ curve, known
as t
