Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for decoding video data, the method comprising: determining a value of a syntax element, the value of the syntax element signaling whether or not sub-picture level coded picture buffer (CPB) removal delay parameters are present in a picture timing Supplemental Enhancement Information (SEI) messages; regardless of a value of a variable, deriving a CPB arrival time for an access unit (AU) and a nominal removal time for the AU at an AU level, wherein…
