JVET-L0467 Multi-component video coding: an extension for truly versatile video/image compression [A. M. Tourapis, Y. Su, K. Mammou, J. Kim, D. Singer, F. Robinet (Apple)] [late]
(The proponent suggested treating this as informative, pending parent body consideration.)
Some modern multimedia applications, and especially virtual reality applications, involve image and video captures with more than 3 components. Additional components, apart from colour information, may include, for example, depth and infrared information, while some applications may use more than 3 colour primaries to best capture or represent colour information. To accommodate such applications, this contribution proposes that the new VVC standard not be designed and limited to support only up to 3 colour components, but instead be made extensible so as to support coding of imagery with multiple colour components in an efficient manner.
It was commented that there may, in some cases, be registration error between different components.
Different sampling ratios for different components may also be applicable (e.g., a 4:1 ratio horizontally or vertically).
This was not a submission for current action. It would need parent body consideration.
