This part of IEC 61966 defines the colour gamut metadata scheme for video systems and similar applications.<\/p>\n
The metadata can be associated with wide gamut video colour content or to a piece of equipment to display the content.<\/p>\n
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\u2019s colour gamut is different from that of the content.<\/p>\n
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.<\/p>\n
The colour gamut metadata may 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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
