IEC 61966-12-1:20 20 RLV包含官方IEC国际标准及其红线版本。Redline版本不是官方文档，它只有英文版本，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 61966-12-1:20 20定义了视频系统和类似应用的色域元数据方案。元数据可以与宽色域视频彩色内容相关联，或者与用于显示内容的一件设备相关联。当与内容相关联时，色域元数据定义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，色域元数据定义显示器色域。它可以在内容创建期间使用，以实现改进的色彩再现。当颜色编码规范未提供此类信息时，色域元数据可以覆盖相关联的颜色编码信息，其包括受控颜色再现所需的所有信息。色域元数据方案提供了可扩展的解决方案。例如，更灵活的解决方案将用于专业用途，而更简单的解决方案将用于消费者用途，产品实施更容易。IEC 61966的这一部分仅定义了色域元数据方案。允许使用特定于供应商的解决方案来创建和最终使用此元数据。IEC 61966-12-1:20 20取消并取代2011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)第6条中增加的ITU-R BT.2020色彩空间； b)第6条中添加的ITU-R BT.2100色彩空间。

IEC 61966-12-1:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it 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 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.
