摘要

Computer readable systems, methods and media are described for improved color remapping. In some examples, a video bit stream is obtained that includes a plurality of images having a first color characteristic. Color remapping information (cri) Supplementary enhancement information message (I know) is identified from the video bit stream. A constraint is placed on the critical message such that a value of a syntax element of the critical message is constrained based on a condition. one or more samples of the plurality of images is remapped from the first color feature to a second color feature using a color remap template of the message created according to the constraint. In some cases, the condition is a chroma format of the plurality of images, in which case the value of the syntax element of the cryptic message is restricted based on the chroma format. in some cases, the condition is a color remap value that identifies a purpose of the cryptic message color remap template, in which case the value of the cryptic message syntax element is restricted based on the remap value of Colors.
