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 (See Fig. 5, item 500). The parameter set is encoded into a metadata file that is associated with the multimedia data (See Fig. 5, item 502). The parameter set is extracted from the metadata file if a decoder configuration record contains fields corresponding to the parameter set (See Fig. 5, item 504). In another aspect, the decoder configuration record is created with fields corresponding to the parameter set (See Fig. 5, item 506).
