Enabling functionalities - details
ITU-T
Service Layer
Architecture
Comm/IPTV
Integration
o
Audio/Video communication
• bringing communication as close as possible
to the TV-set (user perspective)
o
Presence on watched channel
• adding the watched channel in the RPID,
and using it with the other presence
attributes.
o
Exposure for editors
• creating a flexible infrastructure to enable
new TV formats offered together with other
players (content and service providers).

Service Plan integration

o
several coupling relations
allowed, with different level
of integration
reuse of IMS communication
enablers
several device integration
solution allowed (combo,
separated, coupled, …)
Control Layer Integration
(IMS-centric vision)
o IMS core network used to
deliver “IPTV”, seen as
“just another” IMS
application
o reuse of IMS enablers to
deliver communication
services
o “combo” IMS device
The integration should follow the following priorities
•Market (increasing value on IPTV services)
•Architecture (re-using legacy as much as possible)

Conclusions
ITU-T
o
IMS is the right technology in order to PUSH
interactivity on IPTV services, but the focus
must be set on market requirements and
legacy rationalization.
o
The architecture, in order to allow
flexibility on business models, must be
designed to be open, but controlled, to
third parties.
