Highlights of achievements (XII)Lead SG Activities: Multimedia (1/2)

ETS/TDR: in this area, leveraging the efforts from the last Study Period, SG16 has continued to support the organization of workshops and to develop MM capabilities for TDR applications

E-Health: the work has been concentrated on the development of a Technical Paper and a roadmap together with key players in that area. It is expected that new technologies (e.g. RFID) and ongoing projects, will increase the need in future for global and interoperable standards as well as for information on best practices.

Accessibility: high priority and visibility has been given to this work during the Study Period. Tools were developed to include accessibility requirements – from the beginning – in the development of MM systems and terminals, in particular in NGN, IPTV.


16


Highlights of achievements (XIII)

Lead SG Activities: Multimedia (2/2)Developing Countries:

– SG16 took several initiatives to improve the involvement of experts from developing countries in the development of MM standards (e.g. action plan, Correspondence Group, ad hoc meetings,…)

– These efforts should be continued during the next Study Period, with a special focus on the use and applications of SG16 Recommendations.

E-Business/E-commerce:– This theme has been indirectly addressed through all Recs

which support E-B/E-C, in particular on remote collaboration, Home Networking and tag based MM information retrieval.


17


Future Work (I)Future Directions:

– Enhancement and maintenance of existing Recs to ensure smooth and backward compatible evolution of telecommunication equipment and services

– Infrastructure-agnostic architectures as enabler of the “Internet of Things”

– Audio and Video coding: next generation of video coding, innovative audio coding approaches

– Advanced MM System for NGN and beyond

– Ubiquitous sensor networks

– Impact of ICT on climate changes

– Intelligent Transportation Systems: work on vehicle gateway platform and on a dynamic coordination mechanism for signal processing devices to ensure high quality end-to end voice and voiceband signals.


18


Future Work (II)Coordination

– Improve coordination with other key players in light of the convergence fix-mobile-broadcast

Participation– Developing countries: create the conditions and provide the

necessary support to involve experts from the beginning in the development of standards

– Universities/Academia: promote SG16 work in the academic community and support the TSB initiative to facilitate participation from experts to the work of ITU-T in general and of SG16 in particular

– Electronic meeting facilities: promotion of the use of such tools to reduce travelling cost and contribute to the reduction of GHG


19


Conclusion

Many new technology developments happening in SG 16Response to trends and market needs

– Increase in contributions and participation indicate interest of members in this field of work

Opportunities for contribution from developing countries as new system and technology standards are definedSG 16 has been a pragmatic, efficient, high-productivity study group over its 12-years of existence

– Proposed set of Questions reflects that philosophy
