信息技术.沉浸式媒体的编码表示.第5部分:基于视觉体积视频的编码（V3C）和基于视频的点云压缩（V-PCC）

[中文适用范围]： 本文件规定了基于视频编码方法的体积视觉媒体的语法、语义和解码。该文件还指定了重建体积视觉媒体所需的过程，可能还包括后解码、前重构、后重构和自适应等其他过程。 [外文原描述]： This document specifies the syntax, semantics and decoding for visual volumetric media using video‑based coding methods. This document also specifies processes that can be needed for reconstruction of visual volumetric media, which can also include additional processes such as post‑decoding, pre-reconstruction, post‑reconstruction and adaptation.
