DETERMINATION OF POWER CONSUMPTION –

Part 2: Signals and media

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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition IEC 62087-2:2015. A vertical bar appears in the margin
wherever a change has been made. Additions are in green text, deletions are in
strikethrough red text.

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.
This second edition cancels and replaces the first edition published in 2015. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) HDR and UHD video test signals have been added;
b) dynamic box and outline test signals have been added, replacing the static box and outline
test signals;
c) all test signals are provided as media files for download from a specified IEC online
repository, which replaces previous DVD and Blu-ray media.
The text of this International Standard is based on the following documents:
Draft Report on voting
100/3771/CDV 100/3848/RVC
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
A list of all parts in the IEC 62087 series, published under the general title Audio, video, and
related equipment – Determination of power consumption, can be found on the IEC website.
This publication contains multiple test signals downloadable from a specified IEC
online repository, available at https://www.iec.ch/tc100/supportingdocuments. These files
form an integral part of this standard.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The "colour inside" logo on the cover page of this document indicates that it
contains colours which are considered to be useful for the correct understanding of its
contents. Users should therefore print this document using a colour printer.

INTRODUCTION
This document identifies test signals and media to be used to determine power consumption
and related characteristics specified in some other parts of the IEC 62087:2015 series. The
media include Blu-ray Discs™ and DVDs.
1
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.
2
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.
3
IEC 62087-2:2015 (first edition) separates the standard into parts, including this signals and
media part which specifies signals 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
– Part 6: Audio equipment
– Part 7: Computer monitors
