标准范围

ISO/IEC 23090-14:2023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媒体和应用程序格式以及通过MPEG传递机制提供的媒体。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函数(MAF)API,用于表示引擎和这些扩展的媒体访问函数之间的通信。虽然本文档中定义的扩展可以适用于其他场景描述格式,但它们是为ISO/IEC 12113提供的。

ISO/IEC 23090-14:2023 This document specifies extensions to existing scene description formats in order to support MPEG media, in particular immersive media. MPEG media includes but is not limited to media encoded with MPEG codecs, media stored in MPEG containers, MPEG media and application formats as well as media provided through MPEG delivery mechanisms. Extensions include scene description format syntax and semantics and the processing model when using these extensions by a Presentation Engine. It also defines a Media Access Function (MAF) API for communication between the Presentation Engine and the Media Access Function for these extensions. While the extensions defined in this document can be applicable to other scene description formats, they are provided for ISO/IEC 12113.
