ISO/IEC TR 2100-1:20 04描述了基于无处不在的网络的多媒体使用环境，旨在鼓励用于交易数字内容的新商业模式。在这种环境下，内容类型之间的传统界限变得模糊，因为它们都被视为新产品和服务中的多媒体资源。此外，个人越来越意识到他们自己的数字资产资源的商业和内在价值。ISO/IEC TR 21000-1:20 04通过“多媒体框架”的愿景解决了这些问题。这是为了支持可互操作和高度自动化的交易，这是支持这些新型商务所必需的。因此，新的MPEG-21工具实现了用于创建、收集、包装和分发内容的新技术。MPEG-21多媒体框架基于两个基本概念:分配和交易的基本单元(数字项目)的定义以及用户与数字项目交互的概念。数字项目可以被认为是多媒体框架的“什么”(例如，视频集合、音乐专辑)，并且用户可以被认为是多媒体框架的“谁”。ISO/IEC TR 21000-1的第二版已经在ISO/IEC JTC 1/SC 29/WG 11中准备，以反映在MPEG-21多媒体框架的定义上取得的进展。

ISO/IEC TR 2100-1:2004 describes a multimedia usage environment founded upon ubiquitous networks and aimed at encouraging new business models for trading digital content. In this environment, the traditional boundaries between content types blur as they are all treated as multimedia resources in new products and services. Additionally, individuals are becoming increasingly aware of the value, both commercial and intrinsic, of their own digital asset resources. ISO/IEC TR 21000-1:2004 addresses these issues through a vision of the "Multimedia Framework". This is intended to support transactions that are interoperable and highly automated, which are required to support these new types of commerce. Thus, the new MPEG-21 tools enable new techniques for the creation, collection, packaging and distribution of content.

The MPEG-21 Multimedia Framework is based on two essential concepts: the definition of a fundamental unit of distribution and transaction (the Digital Item) and the concept of Users interacting with Digital Items. The Digital Items can be considered the "what" of the Multimedia Framework (e.g. a video collection, a music album) and the Users can be considered the "who" of the Multimedia Framework.

The second edition of ISO/IEC TR 21000-1 has been prepared within ISO/IEC JTC 1/SC 29/WG 11 to reflect the progress made on the definition of the MPEG-21 Multimedia Framework.
