Abstract  Abstract

a video coding device such as video decoder can reach time and CPB at access unit AU of and sub-picture levels are derived for an access unit of the coded picture buffer CPB is configured at least one nominal removal time and with a defined decoding unit DU is value of syntax element independent of the whole AU. the video coding device is further configured to based at least in part on the CPB arrival time and nominal one CPB removal time in determining a removal time of the AU and the at least partially decoded video data based on the AU of the removal time.

A video coding device such as a video decoder may be configured to derive at least one of a coded picture buffer (CPB) arrival time and a CPB nominal removal time for an access unit (AU) at both an access unit level and a sub-picture level regardless of a value of a syntax element that defines whether a decoding unit (DU) is the entire AU. The video coding device may further be configured to determine a removal time of the AU based at least in part on one of the CPB arrival time and a CPB nominal removal time and decode video data of the AU based at least in part on the removal time.
