[中文适用范围]： 本文档指定了对现有场景描述格式的扩展，以支持 MPEG 媒体，特别是沉浸式媒体。 MPEG 媒体包括但不限于使用 MPEG 编解码器编码的媒体、存储在 MPEG 容器中的媒体、MPEG 媒体和应用格式以及通过 MPEG 传送机制提供的媒体。 扩展包括场景描述格式语法和语义以及演示引擎使用这些扩展时的处理模型。 它还定义了媒体访问功能 (MAF) API，用于这些扩展的演示引擎和媒体访问功能之间的通信。 虽然本文档中定义的扩展可适用于其他场景描述格式，但它们是为 ISO/IEC 12113 提供的。 [外文原描述]： This document specifies extensions to existing scene description formats in order to support MPEG media, in particular immersive media.
