This part of IEC 61966 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 is limited to the gamut description of additive three primary colours type displays 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 standard provides the simplest, but unambiguous solution for typical CE devices that are based on colour gamut information communication.
