DYNAMIC RANGE ADJUSTMENT PARAMETER SIGNALING AND ENABLEMENT OF VARIABLE BIT DEPTH SUPPORT

Abstract:

An example device for processing video data includes memory configured to store the video data and one or more processors implemented in circuitry and coupled to the memory. The one or more processors are configured to parse a first parameter set, the first parameter set being signaled in a bitstream data once per sequence of a group of encoded pictures. The one or more processors are configured to parse one or more dynamic range adjustment (DRA) syntax elements in a second parameter set, the second parameter set being signaled in the bitstream and being related to at least one picture in the group of encoded pictures, wherein the parsing of the one or more DRA syntax elements is not dependent on any syntax element of the first parameter set, and process the at least one picture based on the first parameter set and the second parameter set.
