US Patent 9479774 Buffering period and recovery point supplemental enhancement information messages

A video coding device, such as a video decoder, may be configured to decode a buffering period supplemental enhancement information (SEI) message associated with an access unit (AU). The video decoder is further configured to decode a duration between coded picture buffer (CPB) removal time of a first decoding unit (DU) in the AU and CPB removal time of a second DU from the buffering period SEI message, wherein the AU has a TemporalId equal to 0. The video decoder is configured to determine a removal time of the first DU based at least in part on the decoded duration and decode video data of the first DU based at least in part on the removal time.
