Abstract: Standards are technical documents that define precisely the conformance required of users if interoperability is to be achieved. Many people have worked to create a coherent and valuable framework for multimedia delivery and consumption. The novelty and different directions of the MPEG-21 work have lead to new and valuable tests for long-standing MPEG process. MPEG has played a key role in developing the standards behind the explosion of multimedia-enabled consumer devices. The MPEG-1 and MPEG-2 standards are the core technologies behind digital TV, advanced audio coding and DVDs. The MPEG-4 standard has seen success in its use in IP video content, while MPEG-4, part 10 (H.264/AVC) standard is making inroads into the mobile content and broadcasting. MPEG-7 is an extensive standard for the description of multimedia content using eXtensible Markup Language (XML) metadata. Finally, in MPEG-21, the aim is to create a standard that would link together the media coding and metadata standards with access technologies, rights and protection mechanisms, adaptation technology and standardized reporting in order to produce a complete multimedia framework. Thus, MPEG-21 is a major step forward in multimedia standards. It collects together the technologies needed to create an interoperable infrastructure for protected digital media consumption and delivery.
