IEC 62087-2:20 23 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 62087-2:20 23规定了用于确定音频、视频和相关设备（如电视机和计算机显示器）功耗的信号。它还规定了用于确定有时与电视机功耗测量程序相关联的峰值亮度比的信号。此外，该部分还规定了与信号产生相关的设备、接口和精度。IEC 62087-2:20 23取消并取代2015年发布的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: a)增加了HDR和UHD视频测试信号； b)增加了动态盒和轮廓测试信号，取代了静态盒和轮廓测试信号； c)所有测试信号均作为媒体文件提供，可从指定的IEC在线存储库下载，该存储库取代了以前的DVD和蓝光媒体。

IEC 62087-2:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 62087-2:2023 specifies the signals used to determine 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 set power consumption measurement programs. In addition, this part specifies equipment, interfaces, and accuracy related to signal generation. IEC 62087-2:2023 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.
