Filed: 2020-04-20
Abstract: Devices, systems and methods related to management of syntax flags with respect chroma formats in video processing are described. In one representative aspect, a video decoding method includes determining, based on a chroma format of a video comprising a region, whether one or more syntax flags applicable to the region of the video are absent in a syntax structure of a coded representation of the video. The one or more syntax flags are indicative of usage of a luma-dependent chroma residue scaling coding step for representing the region in the coded representation. The luma-dependent chroma residue scaling coding step comprises a scaling process in which a scaling coefficient is derived based on reconstructed luma samples and the scaling process is applied to a chroma residue. The method also includes generating one or more decoded video blocks of the video region by parsing the coded representation according to the determining.
