ELECTRONIC DEVICE FOR ENCODING A BUFFER PARAMETER

摘要

An electronic device for sending a message is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device determines whether a picture is allowed to be decoded on a sub-picture level. If the picture is allowed to be decoded on a sub-picture level, the electronic device generates at least one of a buffer size parameter and a buffer scale parameter. The electronic device sends at least one of the buffer size parameter and the buffer scale parameter.

1. A method for encoding a buffer parameter, comprising:
generating picture level buffer parameters; generating a sub-picture coded picture buffer (CPB) parameter present flag, wherein said sub-picture CPB parameter present flag equal to 1 specify that a CPB operate at an access unit level or said sub-picture level; generating a sub-picture level buffer parameters if said picture is allowed to be decoded on said sub-picture level; specifying a CPB size, wherein
said CPB size is specified by using said picture level buffer parameters when operating at said access unit level orsaid CPB size is specified by using said sub-picture level buffer parameters when operating at said sub-picture level; generating a bitstream including said picture level parameters, said sub-picture level buffer parameters and said sub-picture coded picture buffer (CPB) parameter present flag; and sending said bitstream.
