  7. Statistics (II) • 69new & 136 revised Recommendations approved • 22 Questions assigned by WTSA-2000 • Four new or revised Questions during study period • 20 Questions proposed for the next study period

  8. Highlights of achievements (I) • Modems, facsimile terminals and accessibility to MM systems:- Support of modems connections over IP-based networks (V.150 series).- Improvement of facsimile terminals standards (colour fax: T.42) and real-time communication for Group 3 facsimile over IP based networks (T.38).- Promotion of text conversation standards and development of protocols to support these facilities in and over IP based networks.

  9. Highlights of achievements (II) • MM Platform and Interworking (1/2):- New version of Media Gateway Protocol (H.248) and development of new packages (41 in total).- MM Systems over ISDN (H.320): introduction of support for H.264 and use of additional video channels (H.239).- MM Systems over IP-based networks (H.323): development and approval of Version 5 which includes a number additional functions, enhancement to H.323 related Recs like H.225.0 (call signalling) and H.460 series (generic extensible framework).- Security for MM systems (H.235): further development to Version and approval of Version 3, which includes RAS and NAT/Firewall related aspects.

  10. Highlights of achievements (III) • MM Platform and Interworking (2/2):- Directory services: development of a new series (H.350) allowing the use of LDAP and X.500 directory services for MM conferencing (7 Recs covering H.323, H.320, H.235, SIP and non-standard protocols, call forwarding and preferences).- Mobility management for H.323 systems: development of a new series of Recs (H.500) addressing mobility management of H.323 terminals and users (H.510), security procedures (H.530) and intra/inter domains management related aspects (H.501).- Reference architecture for controlling the QoS and service priority of MM services in heterogeneous networks: approval of a new Rec H.360.

  11. Highlights of achievements (IV) • Media coding (1/2)- Development of a new generation of video coding standards (H.264) in cooperation with MPEG for all applications (distributive and interactive communications) on different platforms (fixed and mobile including IP-based networks), bit rate reduction of more than 50 % for the same level of quality (adopted by the DVD-Forum for High Definition-DVD standard).- Still image coding: continuation of the collaborative work with JPEG (maintenance of the T.80 and T.800 series of Recs).Cooperation to be strengthened in future (e.g joint meeting in 2005).- Wideband speech coding around 16 kbit/s: alignment of G.722.2 with 3GPP AMR-WB specifications (Adaptive Multi-Rate Wideband)

  12. 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 (3G 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

  13. Highlights of achievements (VI) • MM Framework (MEDIACOM-2004) (1/2)- Development and approval of basic Recs for triple-play service deployment based on xDSL technologies in the access network: - creation of a Focus Group in accordance with A.7 - development and approval of two Recs covering the Architecture (H.610) and AOMP aspects (H.611), based on technical specifications prepared in the FS-VDSL Focus Group.- TDR/ETS: considerable efforts spent to identify the MM needs of the different players involved in ETS and TDR, approval of a new question (Q I/16) and creation of the PCP-TDR (Partnership Coordination Panel) as informal platform to contribute to the coordination in the development of ETS/TDR standards in and outside ITU-T among the various organisations involved in this field.

  14. 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 (eHSCG: 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).

  15. Highlights of achievements (VIII) • Lead SG Activities: Multimedia (MEDIACOM-2004)- Project Steering Committee mechanism used for the coordination with IETF (e.g. H248, H.350) and MPEG (e.g. H.264). - Coordination of SG16 involvement in the IP, GII and NGN projects.- Organisation of and participation to several workshops (see next slide).- Workshop follow up on SG16 relevant issues (updating of the work programme and of the questions). • Lead SG Activities: e-commerce and e-business-relevant issues of MM transactions have been addressed in the work on SG16 questions (e.g. under Q G/16 on security)- participation to the UN-ECE MoU management team meetings- new set of questions includes the trends towards “e-everything”

  20. Future Work (I) • MM service capabilities trends:- Large offer of multimedia services and applications (“Anytime, Anywhere, Anyone”), increased complexity of customer segmentation.- Convergence with broadcastingat the service and network levels.- Increased customer needs for higher bandwidth and terminal/service/users mobility (fix/mobile convergence).- Importance of content creation and delivery.

  21. Future Work (II) • Impact on SG16 future work:- Address the higher layers capabilities for ubiquitous services (e-everything)- Decoupling between the higher and lower layers of the NGN (architecture)- Continue to address the interworking issues (evolution of platforms)- Strengthen the coordination efforts (MEDIACOM) within ITU-T/ITU and with other SDOs and Forum/Consortia and make extensive use of existing tools (A-Series of Recs.)
