论文摘要
本文概述了全面的媒体格式(OMAF)标准,第二版,该标准最近已完成。 OMAF指定了用于编码,存储,交付和渲染的媒体格式,包括视频,音频,图像和定时文本。此外,OMAF支持对应于全向摄像机和覆盖图像或在全向背景图像或视频上呈现的视频的多个观点。本文中描述了许多用于多种观点和覆盖的用法方案的示例。 OMAF提供了一个功能工具箱,可以在虚拟现实服务中有选择地使用。因此,本文介绍了OMAF标准中指定的互操作性点,该点可以在实施中使用或必须支持的OMAF功能发出信号。最后,本文总结了第三代合作伙伴项目(3GPP)和虚拟现实行业论坛(VRIF)在虚拟现实服务规范中使用了哪些OMAF互操作性点。
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).
