IEC 61966-12-2:20 24作为IEC 61966-12-2:20 24 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 61966-12-2:20 24规定了用于CE（消费电子）设备的视频系统的色域元数据格式。IEC 61966-12这一部分中规定的元数据仅限于包括三原色加色的显示器类型的色域描述，其白点和黑点具有相同的色度。它从根本上基于传统的VESA-EDID格式。 当与内容相关联时，简单元数据格式定义了为其创建内容的色域。即使显示器的色域不同于内容的色域，它也可以被显示器用于受控的颜色再现。当与显示器相关联时，简单元数据格式定义显示器色域。它可以在内容创建期间使用，以实现改进的色彩再现。 本文档为基于色域信息通信的典型CE设备提供了最简单但明确的解决方案。 IEC 61966-12-2:20 24取消并取代2014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)在条款4中扩展了元数据格式的比特数； b）增加了附件C，用于处理HDR内容。

IEC 61966-12-2:2024 is available as IEC 61966-12-2:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61966-12-2:2024 specifies the colour gamut metadata format for video systems intended for use in CE (consumer electronics) devices. The metadata specified in this part of IEC 61966-12 is limited to the gamut description for display types comprising the three primary additive colours, whose white and black points have the same chromaticity. It is fundamentally based on the conventional VESA-EDID format.
When associated with content, the simple metadata format defines the gamut for which the content was created. It can be used by the display for controlled colour reproduction even if the display’s colour gamut is different from that of the content. When associated with a display, the simple metadata format defines the display colour gamut. It can be used during content creation to enable improved colour reproduction.
This document provides the simplest, but unambiguous solution for typical CE devices that are based on colour gamut information communication.
IEC 61966-12-2:2024 cancels and replaces the first edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the number of bits of metadata format has been extended in Clause 4;
b) Annex C has been added for handling HDR content.
