Embodiment Construction

[0046] It should be understood at the outset that although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of techniques, whether currently known or in existence . The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but rather be within the scope of the appended claims and their equivalents Modified within the full range of .

[0047] Many video compression techniques can be used to reduce video files while minimizing data loss. For example, video compression techniques may include performing spatial (eg, intra) prediction and / or temporal (eg, inter) prediction to reduce or remove data redundancy in a video sequence. For block-based video decoding, a video slice (for example, a video image or a part of a video image) can...

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.

Description

[0001] Cross References to Related Applications [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...
