标准摘要
[中文适用范围]： 本文件定义了用于视频系统和类似应用的色域元数据布局方案。该元数据可与广色域视频内容相关联，也可与用于显示该内容的设备相关联。当与内容关联时，色域元数据定义了创建该内容所用的色域；当与屏幕关联时，定义了屏幕的色域。该布局方案提供可扩展的解决方案，例如，更灵活的方案用于专业用途，而更简单的方案用于消费用途。 [外文原描述]： IEC 61966-12-1:2020 defines the colour gamut metadata scheme for video systems and similar applications. The metadata can be associated with wide-gamut video colour content or to a piece of equipment to display the content. When associated with content, the colour gamut metadata 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 colour gamut metadata defines the display colour gamut. It can be used during content creation to enable improved colour reproduction. The colour gamut metadata can cover associated colour encoding information, which includes all information required for a controlled colour reproduction, when such information is not provided by the colour encoding specification. The colour gamut metadata scheme provides scalable solutions. For example, more flexible solutions will be used for the professional use, while much simpler solutions will be used for consumer use with easier product implementation. This part of IEC 61966 only defines the colour gamut metadata scheme. Vendor-specific solutions for creation and end-use of this metadata are allowed. IEC 61966-12-1:2020 cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) ITU-R BT.2020 colour spaces added in Clause 6; b) ITU-R BT.2100 colour spaces added in Clause 6.
