  • MPEG-21 Today, there are many factors to build an infrastructure for the delivery and consumption of multimedia content. However, there is no “big picture” to describe how these elements, either existing or in development, are interrelated. The purpose of MPEG-21 is to describe how these various elements fit together. Where gaps exist, MPEG-21 recommends which new standards are required. While other relevant standards may be developed by other bodies, MPEG will then develop new standards as appropriate. These specifications will be integrated into the multimedia framework through joint research between MPEG and these organizations.
  • MPEG-21 aims to set a vision for enabling transparent and augmented use of multimedia resources across a wide range of networks and devices used by different communities.
