Abstract

A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a plurality of coded sequences of point cloud coding (PCC) frames, wherein the plurality of coded sequences of PCC frames represent a plurality of PCC attributes including geometry, texture, and one or more of reflectance, transparency, and normal. Each coded PCC frame is represented by one or more PCC network abstraction layer (NAL) units. The mechanism also includes parsing the bitstream to obtain an indication for each of the PCC NAL units that indicates whether each of the PCC NAL units belongs to a corresponding one of the PCC attributes, and to which of the PCC attributes the PCC NAL unit belongs when the PCC NAL unit belongs to the corresponding PCC attribute. The mechanism also includes decoding the bitstream based on the indications.

[0002] This patent application requires U.S. Provisional No. 62 / 731,693, titled "High-Level Syntax Designs for Point Cloud Coding," filed by Wang Yekui et al. on September 14, 2018 interest in the patent application, which is incorporated herein by reference. technical field

[0003] The present invention relates generally to video coding, and in particular, to the coding of video attributes of point cloud coding (PCC) video frames. Background technique

[0004] Even relatively short videos require large amounts of video data to describe, which can create 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 telecommunications networks. Since memory resources may be limited, the size of the video may also be an issue when storing the video on a storage device. Video c...
