标准摘要
[中文适用范围]： IEC 62087 的这一部分规定了用于确定音频、视频和相关设备（例如电视机和计算机显示器）功耗的信号和媒体。它还指定了用于确定有时与电视功耗测量程序相关的峰值亮度比的信号。此外，本部分还规定了与信号生成相关的设备、接口和精度。 [外文原描述]： IEC 62087-2:2015 specifies signals and media used in determination of the power consumption of audio, video, and related equipment, such as television sets and computer monitors. It also specifies signals for determining the peak luminance ratio that is sometimes associated with television power consumption measurement programs. In addition, this part specifies equipment, interfaces, and accuracy related to signal generation. 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. The signals included on the discs are now numbered generically, rather than being based 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. This publication is available in CD-ROM format only. The 5-disc package contains the publication on a CD and video files on two DVDs and two Blu-ray™ Discs.
