Recent video s

35、tandards for wide gamut colour space encoding such as IEC 61966-2-4 (xvYCC) were established in order to be able to distribute content with a colour gamut that is extended with respect to classical colour gamuts such as defined by colorimetry standards ITU-R BT.601 (standard definition television) a

36、nd ITU-R BT.709 (high definition television). With the increasing popularity of wide gamut and high dynamic range content and displays, the variety of colour gamuts of displays is expected to increase. This issue can be an obstacle for adopting wide-gamut video colour content in professional content

37、 creation since the compatibility of the content to the employed displays as well as the compatibility among different displays is not ensured. The term display includes here any video colour reproduction equipment, such as direct view displays and projectors. Thanks to improvements of technology, t

38、he variety of colour gamut and colour reproduction capacities of displays increases while the colour gamut and the colour encoding rules of existing colour space encoding standards are fixed. To address this issue, the IEC standard Gamut ID (IEC 61966-12-1) specifies a colour gamut metadata scheme f

39、or video systems including information for colour reproduction. This metadata can amend a video content or a display. More specifically, improvements can be achieved if the wide-gamut colour content is created with the knowledge of the display colour gamut as well as if the colour reproduction in th

40、e display is done with the knowledge of the colour gamut of the pictorial content. This standard enables video systems defining their own colour gamut. This standard defines necessary metadata that allows managing inhomogeneous video systems with different colour gamuts. This standard generalizes ex

41、isting colour space encoding standards having a fixed colour gamut. BS EN 61966-12-1:201161966-12-1 IEC:2011(E) 7 MULTIMEDIA SYSTEMS AND EQUIPMENT COLOUR MEASUREMENT AND MANAGEMENT Part 12-1: Metadata for identification of colour gamut (Gamut ID) 1 Scope This part of IEC 61966 defines the colour gam

42、ut 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

43、 used by the display for controlled colour reproduction even if the displays 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.

44、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. The colour gamut metadata scheme provides scalable solutions. For exam

45、ple, 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
