ELECTRONIC DEVICES FOR SIGNALING SUB-PICTURE BASED HYPOTHETICAL REFERENCE DECODER PARAMETERS

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 to include a common decoding unit CPB removal delay parameter in a picture timing Supplemental Enhancement Information (SEI) message. The electronic device also generates either a common decoding unit CPB removal delay parameter or a separate decoding unit CPB removal delay parameter for each decoding unit in the access unit. The electronic device also sends the picture timing SEI message with the common decoding unit CPB removal delay parameter or the decoding unit CPB removal delay parameters.
