Such as video decoder equal video coding device may by arranged to decode and access unit AU each relevant buffer period supplemental enhancement information and SEI information. The video decoder through further configuration for the buffer period SEI from decoding of the message AU and the first decoding unit DU through coding the image buffer CPB removing time and CPB is the second DU removing the lasting time between time wherein the AU equal to 0 and with TemporalId. The video decoder by configuration to at least part based on the decoding by determining the duration time of the first DU is removed and at least part based on the removing time decoding the DU of the first video frequency data.

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.
