SUPPORTING FIDELITY RANGE EXTENSIONS IN ADVANCED VIDEO CODEC FILE FORMAT

摘要

A parameter set is created to specify chroma format, luma bit depth, and chroma bit depth for a portion of multimedia data. The parameter set is encoded into a metadata file that is associated with the multimedia data. The parameter set is extracted from the metadata file if a decoder configuration record contains fields corresponding to the parameter set. In another aspect, the decoder configuration record is created with fields corresponding to the parameter set.
