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