Electronic devices for sending a message and buffering a bitstream
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 first picture is a Clean Random Access (CRA) picture. The electronic device also determines whether a leading picture is present if the first picture is a CRA picture. The electronic device further generates a message including a CRA discard flag and an initial CRA Coded Picture Buffer (CPB) removal delay parameter if a leading picture is present. The electronic device additionally sends the message.
1. A method for sending a buffering period Supplemental Enhancement Information (SEI) message by an electronic device, comprising:
coding first initial CPB removal delay parameters, a flag which indicates whether second initial CPB removal delay parameters are present, and second initial CPB removal delay parameters when the flag indicates its presence,
wherein
initial removal delay variables is set to second initial cpb removal delay parameters when a set of conditions is met, and initial removal delay variables is set to first initial cpb removal delay parameters when the set of conditions is not met,
and sending the buffering period Supplemental Enhancement Information (SEI) message.
