Question 4/16 - Advanced multimedia communication service features on top of the ITU-T defined multimedia system platforms |
|
(Continuation of Question 4/16)
- Motivation
ITU-T Study Group 16 has focused on the H.300-, H.248- and T.120-series standardization of real-time audiovisual
conversational system platforms over various types of network. The network infrastructure to support these
multimedia system platforms is converging to the IP-based one which has been developed to provide rich Internet
services such as e-mail, hypertext multimedia data retrieval, multimedia file transfer, multimedia streaming,
presence, instant messaging. We have a good opportunity of utilizing these Internet services and other new service
features in conjunction with audio, video and data capabilities of the multimedia system platforms standardized by
SG 16. H.350-series to provide directory services for H.323 and H.320 videoconferencing systems is such an example.
This Question addresses how to provide advanced service features on top of the SG 16 defined platforms for such
multimedia services as videophone, videoconferencing, data conferencing, distance learning, e-health, interactive
multimedia information distribution, realtime multimedia collaboration in the NGN environments.
- Study Items
- Architecture to integrate advanced service features with the SG 16 defined multimedia system platforms
- Protocols to implement the above integration.
- Mechanism of synchronization between audiovisual and other service presentations.
- Multipoint aspects of the integrated systems.
- Convergence of telecommunication and broadcasting services
- Verification tests for interoperability.
- Alignment with goals related to the Mediacom and NGN Projects.
- Tasks
Tasks include, but are not limited to:
- Maintenance and enhancements of H.350-series
- Use of presence in H.300-series systems
- Definition of new services and their technical requirements capture
- Protocol specifications
- Verification of the protocol to be standardized
An up-to-date status of work under this Question is contained in the
SG 16 Work Programme.
