标准范围
ISO/IEC 23000规定了数字项结构、文件格式，并参考了媒体流环境中使用的一组协议，用于通过现有协议（如MPEG-2传输流或互联网实时协议（RTP/IP））将受管音频和视频信息流传输到最终用户设备的应用，并提供了一套与特定应用相对应的信息性实现。ISO/IEC 23000为视听信息和相关数据的流式传输提供了标准化解决方案，以促进不同设备和平台之间简单且完全可互操作的交换。媒体流应用格式允许一致性设备访问受管理或不受管理的音频和视频信息，并使用各种方式到达最终用户设备。ISO/IEC 23000-5:2008中规定的媒体流内容格式依赖于许多MPEG技术，如ISO/IEC 21000-2、ISO/IEC 21000-3、ISO/IEC 21000-4、ISO/IEC 21000-5、ISO/IEC 21000-9、ISO/IEC 21000-18，以及几种MPEG技术-与音频/视频编码相关的2/4标准，因为该MAF为某些应用场景指定了“本机”资源。ISO/IEC 23000-5:2008全面引用了上述一些国际标准，而其他标准仅以特定方式部分使用。
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.
