47、All rights reservedExecutive Summary for MPEG-21 Today, many elements exist to build an infrastructure for the delivery and consumption of multimedia content. There is, however, no “big picture“ to describe how these elements, either in existence or under development, relate to each other. The aim f
48、or MPEG-21 is to describe how these various elements fit together. Where gaps exist, MPEG-21 will recommend which new standards are required. ISO/IEC JTC 1/SC 29/WG 11 (MPEG) will then develop new standards as appropriate while other relevant standards may be developed by other bodies. These specifi
49、cations will be integrated into the multimedia framework through collaboration between MPEG and these bodies. The result is an open framework for multimedia delivery and consumption, with both the content creator and content consumer as focal points. This open framework provides content creators and service providers with equal opportunities in the MPEG-21 enabled open market. This will also be to the benefit of the content consumer providing them access to a large va
