IEC 61966的这一部分定义了视频系统和类似应用的色域元数据方案。 元数据可以与广域视频彩色内容相关联，也可以与显示内容的设备相关联。 当与内容关联时，色域元数据定义了为其创建内容的色域。即使显示器的色域与内容的色域不同，它也可以被显示器用于受控的颜色复制。 当与显示器关联时，色域元数据定义显示器的色域。它可以在内容创建期间使用，以改进颜色再现。 色域元数据可以涵盖相关的颜色编码信息，其中包括受控颜色复制所需的所有信息（如果颜色编码规范未提供此类信息）。 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，更易于产品实施。 IEC 61966的本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。 购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 61966 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.All current amendments available at time of purchase are included with the purchase of this document.
