Abstract  Abstract

Such as video decoder equal video coding device may by arranged to access unit at AU level and sub picture level both to derive access unit is used for coding image by CPB arrival time and buffer CPB weight is removed and the at least one time and then decoding unit DU if defined as syntax element of the whole AU and value. The video coding device may further by configuration to at least part based on the CPB arrival time and CPB weight is removed and one time and removing time and confirming the AU and at least part based on the removing time decoding video frequency data and the AU.

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.
