Highlights of achievements (V) • Media coding (2/2) - 4 kbit/s speech coding: considerable efforts spent to identify and assess two possible candidates towards a single standard. No consensus was possible among the proponents, the work is suspended since October 2002. - Variable bit rate coding of speech signals: definition of target performance objectives to support a large number of applications (3 G wireless services, VOIP, very low bit rate PSTN, CME, PCME, …), corresponding Recs are planned for 2005/2006. - Maintenance of existing standards and of software tools for audio coding development ITU-T Study Group 16 MM Services, Systems and Terminals 12

Highlights of achievements (VII) • MM Framework (MEDIACOM-2004) (2/2) - e-Health: approval of a new question (Q J/16: MM Framework for e-Health application) to study the standardisation of MM service facilities to support the various e-Health applications (e. g. telemedecine) and creation of an informal platform (e. HSCG: e-Health Standardisation Coordination Group) to exchange information and identify possible standardisation issues among the different communities involved in this area. - Development of a Metadata Framework to allow content and/or broadcast program information to be delivered over different networks and terminals (F. MDF). ITU-T Study Group 16 MM Services, Systems and Terminals 14
