全向MediA格式（OMAF）：用于虚拟现实服务的VoIP
Omnidirectional MediA Format (OMAF): Toolbox for Virtual Reality Services
摘要：
本文概述了全向媒体格式（OMAF）标准，第二版，这是最近完成的。OMAF指定了用于编码、存储、交付和呈现全向媒体的媒体格式，包括视频、音频、图像和定时文本。另外，OMAF支持与全向相机相对应的多个视点以及在全向背景图像或视频上渲染的覆盖图像或视频。本文中描述了多视点和覆盖的使用场景的许多示例。OMAF提供了一个功能工具箱，可以有选择地用于虚拟现实服务。因此，本文介绍了OMAF标准中规定的互操作性点，这些点可以指示使用中或需要在实现中支持哪些OMAF功能。最后，本文总结了OMAF互操作点已被用于虚拟现实服务规范的第三代合作伙伴计划（3GPP）和虚拟现实产业论坛（VRIF）。
英文摘要：
This paper provides an overview of the Omnidirectional Media Format (OMAF) standard, second edition, which has been recently finalized. OMAF specifies the media format for coding, storage, delivery, and rendering of omnidirectional media, including video, audio, images, and timed text. Additionally, OMAF supports multiple viewpoints corresponding to omnidirectional cameras and overlay images or video rendered over the omnidirectional background image or video. Many examples of usage scenarios for multiple viewpoints and overlays are described in the paper. OMAF provides a toolbox of features, which can be selectively used in virtual reality services. Consequently, the paper presents the interoperability points specified in the OMAF standard, which enable signaling which OMAF features are in use or required to be supported in implementations. Finally, the paper summarizes which OMAF interoperability points have been taken into use in virtual reality service specifications by the 3rd Generation Partnership Project (3GPP) and the Virtual Reality Industry Forum (VRIF).
