Claim 12:
13. An encoder comprising:
a processor configured to:
encode a sequence of point cloud compression (PCC) components into a bitstream according to video point cloud compression (V-PCC), the PCC components containing three dimensional objects represented by three dimensional clouds of points;
encode into the bitstream a buffering period supplemental enhancement information (SEI) message and an atlas frame timing SEI message;
perform a hypothetical reference decoder (HRD) conformance check on the bitstream starting at a coded atlas access unit (AU) associated with the buffering period SEI message; and
remove decoding units from a coded atlas buffer (CAB) in the HRD during the HRD conformance check as specified by the atlas frame timing SEI message.
