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. An electronic device for encoding a buffer parameter, comprising:
circuitry configured to generate picture level parameters; generate a first flag, wherein said sub-picture CPB present flag equal to 1 specify that a CPB operate at an access unit level or said sub-picture level; generate a sub-picture level buffer parameters if said first flag is equal to 1; perform a sub-picture level coded picture buffer (CPB) operation based on said sub-picture level buffer parameters or a CPB operation based on said picture level parameters set a second flag equal to 0 when said CPB operation is performed or equal to 1 when said sub-picture level CPB operation is performed; and specify a CPB size, wherein said CPB size is specified by using said picture level parameters when said second flag is equal to 0 or said CPB size is specified by using said sub-picture level buffer parameters when said second flag is equal to 1.
