标准摘要
[中文适用范围]： 本部分IEC 61966-12规定了用于消费电子(CE)设备的视频系统的色彩范围元数据格式。本部分IEC 61966-12中规定的元数据仅限于包含三种原色加法色彩的显示类型的色彩范围描述，其白点和黑点具有相同的色度。它基本上基于传统的VESA-EDID格式。 当与内容相关联时，简单的元数据格式定义了内容创建的色彩范围。即使显示器的色彩范围与内容的色彩范围不同，显示器也可以使用它进行受控的色彩再现。 当与显示器相关联时，简单的元数据格式定义了显示器的色彩范围。它可以在内容创建过程中使用，以实现改进的色彩再现。 本文档为基于色彩范围信息通信的典型CE设备提供了最简单但明确的解决方案。 [外文原描述]： 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.
