SUB-BITSTREAM EXTRACTION |
| 摘要 |
A sub-bitstream extraction process is applicable to a bitstream of multiple access units comprising a respective encoded picture of a video sequence. 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. |

1. A sub-bitstream extraction method applicable to a bitstream of multiple access units comprising a respective encoded picture of a video sequence, said method comprising:
identifying an access unit among said bitstream comprising said multiple access units; and discarding said access unit and all access units in said bitstream that can depend on said access unit to form a sub-bitstream having no access unit that can depend on said access unit. |
