Expanded decoding unit definition

摘要: A video coding device, such as a encoder or decoder, may be configured to decode duration between coded picture buffer (CPB) removal time of first decoding unit (DU) in an access (AU) and CPB second DU, wherein the DU comprises non-video layer (VCL) network abstraction (NAL) with nal_unit_type equal UNSPEC0, EOS_NUT, EOB_NUT, range RSV_NVCL44 RSV_NVCL47 UNSPEC48 UNSPEC63. The decoder determines based at least part on decoded decodes data time.
