标准范围

ISO/IEC 23090-2:20 19本文件规定了全向媒体（包括视频、图像、音频和定时文本）的编码、存储、交付和渲染的全向媒体格式。在OMAF播放器中，用户的观看视角是从球体的中心向外朝向球体的内表面看。注1在本文档中，仅支持3个自由度（3DOF）。换句话说，用户的纯平移移动不会导致向用户呈现不同的全向媒体。对于具有立体视频的3DOF支持，当用户滚动他/她的头部时，可能存在立体渲染问题。注2全向视频可以包含由计算机图形生成但被编码为视频的图形元素。

ISO/IEC 23090-2:2019 This document specifies the omnidirectional media format for coding, storage, delivery, and rendering of omnidirectional media, including video, images, audio, and timed text.
In an OMAF player the user's viewing perspective is from the centre of the sphere looking outward towards the inside surface of the sphere.
NOTE 1 In this document, only 3 degrees of freedom (3DOF) is supported. In other words, purely translational movement of the user does not result in different omnidirectional media being rendered to the user. For 3DOF support with stereoscopic video, when the user rolls his/her head, there could be a stereoscopic rendering issue.
NOTE 2 Omnidirectional video could contain graphics elements generated by computer graphics but encoded as video.
