SUB-BITSTREAM EXTRACTION

摘要

A sub-bitstream extraction process is applicable to a bitstream of multiple access units comprising a respective encoded picture (2) of a video sequence (1). An access unit among the bitstream is identified and discarded. In addition, all access units in the bitstream that can depend on this access unit are discarded to form a sub-bitstream. The sub-bitstream will not have any access unit that can depend on the identified access units and will be a specification-conforming bitstream.
