  36. SG16 challenges SG16 should: • Continue to extend and improve the existing standardization framework according to the market needs • Develop a new flexible concept to support MM capabilities on NGN and future networks: • existing Services and applications (evolution!) • new ubiquitous Services and Applications (any devices, anytime, anywhere) • Leverage its knowledge in MM Systems and Services to lead the NGN work at the Service and Application layers • Use its expertise and experience to establish a coordination in and outside ITU-T (e.g. IETF, ETSI,…) on a 3rd generation of MM Systems and Terminals IMTC Forum – May 2005 – Eibsee, Germany

  37. Conclusions • SG16 has been successful in a number of areas and hold most of the top-ten ITU-T Recs • Through NGN, ubiquitous services and applications and the different types of convergences, the market is evolving very fast • There is a at present an urgent need to improve the coordination for the development of the NGN higher layers to support MM services and applications • SG16 has to become a “true” MM-Study Group and leverage its experience to extend its leadership to the new environment (any device, anytime, anywhere) IMTC Forum – May 2005 – Eibsee, Germany

  38. Mr Pierre-André Probst has been a major contributor to the ITU-T work, starting back in 1970s as a delegate, then WP Chair and Study Group Chairman in the 1993-1996 Study Period. Since 1997 he is the chair of SG 16 where he has helped flourish the multimedia work in ITU–from modems to videoconferencing and VoIP to audio and video coding–and has significantly contributed to the organization of many ITU-T workshops and related events. In parallel with his ITU-T participation, he led a very active professional life at Swisscom with a full range of responsibilities; starting as an Engineer, he retired a few years ago as Member of the Management Board and Executive Vice President for Corporate Operations. Now he acts as independent consultant in the area of ICT. Thank you! IMTC Forum – May 2005 – Eibsee, Germany
