A video coding device, such as a video encoder or a video decoder, may be configured to decode a duration between coded picture buffer (CPB) removal time of a first decoding unit (DU) in an access unit (AU) and CPB removal time of a second DU, wherein the first DU comprises a non-video coding layer (VCL) network abstraction layer (NAL) unit with nal_unit_type equal to UNSPEC0, EOS_NUT, EOB_NUT, in the range of RSV_NVCL44 to RSV_NVCL47 or in the range of UNSPEC48 to UNSPEC63. The video decoder determines a removal time of the first DU based at least in part on the decoded duration and decodes video data of the first DU based at least in part on the removal time. |
