How does MPEG-21 relate to the other MPEG standards?


The MPEG standards cover different areas. Broadly speaking, they can be broken into:

  • MPEG-1, 2, 4 Coding of audio/visual content
  • MPEG-7 Providing metadata that describes multimedia content
  • MPEG-21 Providing a framework for the all-electronic creation, production, delivery and trade of content. Within the framework we can use the other standards (including, but not limited to, MPEG) where appropriate.
