100 FOREWORD

101 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

102 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

103 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

104 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

105 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

106 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

107 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

108 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

109 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

110 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

111 consensus of opinion on the relevant subjects since each technical committee has representation from all

112 interested IEC National Committees.

113 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

114 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

115 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

116 misinterpretation by any end user.

117 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

118 transparently to the maximum extent possible in their national and regional publications. Any divergence between

119 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

120 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

121 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

122 services carried out by independent certification bodies.

123 6) All users should ensure that they have the latest edition of this publication.

124 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

125 members of its technical committees and IEC National Committees for any personal injury, property damage or

126 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

127 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

128 Publications.

129 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

130 indispensable for the correct application of this publication.

131 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

132 rights. IEC shall not be held responsible for identifying any or all such patent rights.

133 International Standard IEC 62087-2 has been prepared by technical area 19: Environmental

134 and energy aspects for multimedia systems and equipment, of IEC technical committee 100:

135 Audio, video and multimedia systems and equipment.
136 This edition constitutes a technical revision.

137 This second edition of IEC 62087-2 includes the following significant technical changes with

138 respect to IEC 62087-2:2015:
139 - HDR and UHD video test signals have been added.

140 - Dynamic box and outline test signals have been added, replacing the static box and

141 outline test signals.

142 - All test signals are provided as media files for download from a specified IEC online

143 repository, which replaces previous DVD and Blu-ray media.

166 INTRODUCTION

167 This document identifies test signals to be used to determine power consumption and related

168 characteristics specified in some other parts of the IEC 62087 series.

169 IEC 62087:2008 (second edition) added methods for measuring On (average) mode power

170 consumption of televisions, based on three video signal sets. These include static, dynamic

171 broadcast-content, and Internet-content signals.

172 IEC 62087:2011 (third edition) revised methods for measuring power consumption of set top

173 boxes. The signals and media were not changed in this third edition.

174 IEC 62087-2:2015 (first edition) separates signals and media that are to be used for

175 determining power consumption and related characteristics into a dedicated part. The three

176 original video signal sets (static, dynamic broadcast-content, and Internet-content) are not

177 changed. This edition adds signals for the purpose of determining the peak luminance ratio that

178 is sometimes associated with television power consumption measurement programs.

179 This second edition of IEC 62087-2 adds HDR and UHD video test signals and dynamic box

180 and outline test signals for TV power consumption testing. All test signals are available from a

181 specified IEC online repository for download, replacing former physical media distribution.

294 one set of transfer functions offering a degree of backwards compatibility by more closely

295 matching the previously established television transfer curves

296 Note 1 to entry: Sets of transfer functions related to HDR signals are specified in Rec. ITU-R BT.2100-2.

297 Note 2 to entry: HLG is used both as a description of a dedicated transfer function and as a video format name.

304 EXAMPLE An HDR video signal typically uses a greater bit depth, luminance and colour volume than standard

305 dynamic range (SDR) video. It also typically utilizes different tone curves such as perceptual quantizer (PQ) or hybrid

306 log gamma (HLG) as specified in ITU-R BT.2100 instead of gamma, as used with SDR. When the HDR video signal

307 is rendered on an HDR display, it is possible to see greater luminance ranges and wider colour gamut

308 Note 1 to entry: HDR video can provide an enhanced viewer experience and can more accurately reproduce scenes

309 that include, within the same image, deep dark areas, and bright highlights, such as emissive light sources and

310 reflections.
