• To raise awareness and participation of audio interests in MPEG-7.
• To refine MPEG-7 Audio Applications, Requirements and FAQs.
• To discuss MPEG-7 aspects specific to audio.
• To encourage donation & distribution of additional audio material for MPEG-7

• To seek solutions to such deficiencies in MPEG-4 as the absence of a back channel for both audio and SNHC objects to activate trick modes (i.e. skip ahead, skip back) in an MPEG-4 scene (such as talking head)
• To propose a unified structure for back channel syntax when appropriate.

1. Using draft revision 7a (M4290), M4287 and the material generated at the Roma meeting, improve MPEG-7 Requirements, addressing the following issues:

  • more explanation in pictures
  • better wording to make requirements clearer in some places
  • typographical improvements:
  • • make clear distinction between Requirements, Notes, Examples
  • Usage of 'must', will' à shall
  • logical ordering of requirements
  • Adding UML diagram and removing figure 2 (agreed)
  • Consistency within document
  • Definition of DDL vs. requirements (definition of new Ds)
  • Terminology
  • • apply existing definitions consistently
    • supply new definitions for words that may be misinterpreted
  • Consistency with other documents
  • 'Framework' vs. C&O
  • terminology in FAQ
  • More examples
  • e.g. mention 'namespace' under 'unique identification'
  • Definition of 'feature'
