PRIORITIES (II)

• MEDIACOM 2004 general framework for the next
  generation of MM standards
• Focus on mobility, ease of use, systems
  flexibility, end-to-end interoperability,
  specific quality requirements
• Support of harmonised and co-ordinated
  development of global multimedia communication
  standards across all ITU-T and ITU-R SGs in close
  co-operation with other SDOs

• CONCLUSIONS
• Different types of convergence are under way
• Threat to introduce on the market standards which
  are not compatible or interoperable
• An increased number of SDOs and industry forums
  are defining standards
• Need for better communications between the
  business communities involved
• MEDIACOM-2004 will be used as instrument to
  coordinate the development of MM standards
