Abstract

A video coding mechanism is disclosed. The mechanism includes encoding a sequence of point cloud compression (PCC) components into a bitstream. A buffering period supplemental enhancement information (SEI) message is also encoded into the bitstream. A hypothetical reference decoder (HRD) is initialized at a coded atlas access unit (AU) associated with the buffering period SEI message. A HRD conformance check of the bitstream is performed starting at the coded atlas AU. The bitstream is stored for communication toward a decoder.

Description

[0001] Cross References to Related Applications [0002] This patent application requires the invention titled "High-Level Syntax Improvements For Video-Based PointCloud Compression (High-Level Syntax Improvements For Video-Based PointCloud Compression)" submitted by Wang Yekui on June 27, 2019 No. 62 / 867,563 The benefit of the United States Provisional Patent Application, which is incorporated herein by reference. technical field [0003] The present invention relates generally to video coding, and in particular to improvements to support hypothetical reference decoder (HRD) compliance testing in video pointcloud coding (V-PCC). Background technique [0004] Even relatively short videos require large amounts of video data to describe, which can cause difficulties when the data is to be streamed or otherwise transmitted over communication networks with limited bandwidth capacity. Therefore, video data is usually compressed before being transmitted over modern telecommunicat...
