标准范围

MPEG-A促进了创新的、基于标准的多媒体应用和服务的快速发展。为此，MPEG-A引入了一组标准化多媒体应用格式(MAFs)以及它们的相关软件实现。该规范性软件演示了如何使用MAFs，并为供应商开发基于MAFs的多媒体产品提供了一个良好的开端。MPEG对MAFs的最终目标是通过在应用层增加不同媒体类型的互操作性来刺激MPEG技术的使用。尽管在过去MPEG已经指定了配置文件，即标准的特定部分内的技术子集，例如MPEG-2视频，但它从未建议在标准的不同部分使用配置文件的特定组合，例如MPEG-2视频。2音频和MPEG-2视频，或跨不同标准，如MPEG-4和MPEG-7。正是这种跨MPEG标准的技术组合是MPEG-A的主题。ISO/IEC TR 23000-1:20 07包含了对这一新标准族的原始动机的描述，以及构成ISO/IEC 23000的所有其他部分（MAF）的基本概念。此外，它还简要概述了迄今为止已标准化的所有MAF。

MPEG-A facilitates the swift development of innovative, standards-based multimedia applications and services. To this end, the MPEG-A introduces a set of standardized Multimedia Application Formats (MAFs), together with their related software implementation. The normative software demonstrates how MAFs are used and offers vendors a head start for developing multimedia products based on MAFs. MPEG's ultimate objective for MAFs is to stimulate the increased use of MPEG technology through additional interoperability of different media types at the application level. Although in the past MPEG has specified profiles, subsets of technologies within specific parts of the standards, such as MPEG-2 Video, it has never recommended the use of specific combinations of profiles across different parts of a standard, such as MPEG-2 Audio and MPEG-2 Video, or across different standards, such as MPEG-4 and MPEG-7. It is this combination of technologies across MPEG standards which is the topic of MPEG-A.

ISO/IEC TR 23000-1:2007 contains a description of the original motivation for this new family of standards and the concept underlying the construction of all other parts (MAFs) of ISO/IEC 23000. Furthermore, it provides a short overview of all MAFs that have been standardized to date.
