Claim 0:
1. A method implemented by an encoder, the method comprising:
encoding 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;
encoding into the bitstream a buffering period supplemental enhancement information (SEI) message and an atlas frame timing SEI message;
initializing a hypothetical reference decoder (HRD) at a coded atlas access unit (AU) associated with the buffering period SEI message;
performing a HRD conformance check on the bitstream starting at the coded atlas AU; and
removing 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.
