Future Work
SG participation indicators relatively stable: continued interest
from membership
–
subordinate groups: participation increased (FG AVA, JCTs with JTC1)
Main production is "home grown" (rather than rubberstamping)
Coordination with external players remain high on the agenda
Continue focus on infrastructure-agnostic MM architectures that
enable high layer applications such as:
–
–
–
–
–
–
–
Accessibility for persons with disabilities
New and enhanced services and systems: IPTV, Digital Signage
Internet of Things*
Intelligent Transportation Systems*
E-health
Media coding
Enhancing existing families of standards
* Lead SG role proposed

Conclusion
Successful in the 2009-2012 period
Large production, sustained participation
despite economic crisis
Increased interest on infrastructure-agnostic
systems and services
Several strong lines of work
–
Keep nurturing and adjusting course
Cross-sector areas require additional effort
for getting started
–
–
ITS, e-health
Innovative working methods are needed

Thank you!
Mr Yushi Naito is chairman of ITU-T Study Group
16, managing creation of ITU-T standards in the area
of multimedia coding, systems and applications.
Mr Naito is a Senior Technical Adviser at the
Information Technology R&D Center of Mitsubishi
Electric Corporation, where he started in 1975
developing satellite communication systems, and
later worked in research and development of speech
coding and network signal processing equipment.
His ITU experience started in 1990 with network signal processing
equipment standardization in ITU-T Study Group 15, taking the
lead role of Rapporteur in 1992 and later becoming Working Party
chairman in SG 15 and in SG 16, before assuming SG 16
chairmanship in 2008. He also contributed to standardization in
ITU-T Study Groups 9, 11, 12 and 13.
He regularly contributes to other ITU-T activities, in particular
IPTV and ITS/Vehicular Communications (in particular ITU-T Focus
Groups FG-FITCAR, FG-FITCAR II and FG-CarCOM).
