Highlights of achievements (I)
Introduction
Major changes in the Telecom industry during the Study Period 2005-2008
that impacted SG16 activities:
NGN: development of standards for the transition and deployment of NGN
(including fix-mobile convergence).
IPTV: network-agnostic standards for IPTV-Terminals and middleware
RFID: tag-based ID triggered MM information access system
USN: broad range of potential applications, need to standardize an
information service infrastructure.
ITS: In-vehicle network is becoming a key element for various
applications (safety, maintenance, navigation, mobile office, etc), a
standardized gateway platform should be developed.
ICT and climate changes: SG16 can provide solutions for monitoring
climate parameters (USN) and contribute directly/indirectly to reduce GHG
production.
Accessibility: increased interest and commitments of the
telecommunication community to include the need of this category of
users from the beginning in telecommunication systems

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.

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.

Conclusion
Many new technology developments happening in
SG 16
Response 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 defined
SG 16 has been a pragmatic, efficient, highproductivity study group over its 12-years of
existence
