Abstract
This disclosure relates to processing video data, including processing video data that is represented by an HDR/WCG color representation. In accordance with one or more aspects of the present disclosure, one or more syntax structures may be used to signal syntax elements and or other information that allow a video decoder or video postprocessing device to reverse the dynamic range adjustment (DRA) techniques of this disclosure to reconstruct the original or native color representation of the video data. Dynamic range adjustment (DRA) parameters may be applied to video data in accordance with one or more aspects of this disclosure in order to make better use of an HDR/WCG color representation, and may include the use of global offset values, as well as local scale and offset values for partitions of color component values.
