HRD SIGNALING HRD PARAMETERS FOR BITSTREAM PARTITIONS

摘要

In one example, a device for coding (eg, encoding or decoding) video data includes a memory for storing data of the bitstream, and based on whether virtual reference decoder (HRD) parameters are coded for the bitstream. Determine the initial arrival delay syntax element of the bitstream partition initial arrival time supplemental enhancement information (SEI) message of the bitstream, and in response to determining to code the initial arrival delay syntax element, the initial arrival delay syntax element. It includes a video coder configured to code the. The video coder arrives initially only if VclHrdBpPresentFlag for the bitstream has a value of true, e.g. only if the video coding layer (VCL) HRD parameters are coded in the bitstream or it is determined that VCL HRD operations are needed in the bitstream. You may decide to code the delay syntax element.
