标准摘要
[中文适用范围]： ISO/IEC 23000 指定了数字项结构、文件格式，并引用了媒体流环境中使用的一组协议，这些协议适用于通过现有协议（例如 MPEG）将受控音频和视频信息流式传输到最终用户设备的应用程序-2 传输流或基于互联网协议的实时协议（RTP/IP），并提供一组与特定应用相对应的信息丰富的实现。 注 ISO/IEC 23000 为视听信息和相关数据流提供标准化解决方案，以促进不同设备和平台之间简单且完全可互操作的交换。 媒体流应用程序格式允许合格设备访问受监管或不受监管的音频和视频信息，并使用各种方式到达最终用户设备。 ISO/IEC 23000 本部分规定的媒体流内容格式依赖于多种 MPEG 技术，例如 ISO/IEC 21000-2、ISO/IEC 21000-3、ISO/IEC 21000-4、ISO/IEC 21000 -5、ISO/IEC21000-9、ISO/IEC21000-18 以及与音频/视频编码相关的多个 MPEG-2/4 标准，因为该 MAF 为某些应用场景指定了“本机”资源。 上述部分国际标准被 ISO/IEC 23000-5 完整引用，而其他国际标准则仅以特定方式部分使用。 [外文原描述]： ISO/IEC 23000 specifies a digital item structure, a file format, and references a set of protocols used in a media streaming environment for applications where governed audio and video information is streamed to an end-user device by means of existing protocols such as MPEG-2 Transport Stream or Real Time Protocol over Internet Protocol (RTP/IP), and provides a set informative implementations corresponding to specific applications. ISO/IEC 23000 offers a standardized solution for the streaming of audio-visual information and related data to facilitate simple and fully interoperable exchange across different devices and platforms. The Media Streaming Application Format allows conforming devices to access audio and video information that is governed or ungoverned, and reaches end user devices using a variety of means. The format of the media streaming content specified in ISO/IEC 23000-5:2008 relies on a number of MPEG technologies such as ISO/IEC 21000‑2, ISO/IEC 21000‑3, ISO/IEC 21000‑4, ISO/IEC 21000‑5, ISO/IEC 21000‑9, ISO/IEC 21000‑18, as well as on several MPEG-2/4 standards related to audio/video encoding, as this MAF specifies “native” resources for some application scenarios. Some of the International Standards mentioned above are referenced in their entirety by ISO/IEC 23000-5:2008, whilst others are only used partially, and in a specific way.
