摘要：
A method includes encoding target parameters describing characteristics for a target color space for a video picture to be displayed in the target color space and encoding color transform parameters that facilitate remapping the video picture to the target color space. A method includes decoding target parameters describing characteristics for a target color space for a video picture to be displayed in the target color space, decoding color transform parameters that facilitate remapping the video picture to the target color space, remapping the video picture to the target color space utilizing at least one of the decoded color transform parameters, and displaying the remapped video picture in the target color space. The color transform parameters represent at least three successively applied color transforms comprising a first color transform followed by a second color transform followed by a third color transform. Related apparatus for each method are described.
