User Requirements
o Key user requirements for ITV include• TV content choice in fixed and mobile
formats• interactive applications, inc. games, e-
commerce, etc• ubiquitous ‘converged service’ availability –
home, office, vehicle and on-the-move• variety of fixed and mobile devices• access from many network types

Converged Services Evolution
Triple-Play
Video/TV
Voice
Broadband Internet
Quad-Play
FMC
o IPTV must co-exist with video services that are not reliant on IP, eg. traditional broadcast and 3GPP-MBMS
o IPTV promises to provide a generic video solution to drive Quad-Play and beyond
o Examples of Quad-Play service scenarios:• alliance of wireless operator with cable MSO• alliance of wireless operator with telco• combined fixed-mobile operator
FMC = Fixed-Mobile Convergence

DVB- IP Datacast
o DVB-IPDC specifies a bearer-agnostic IP basedplatform for the deliveryof broadcast content to mobile devices
o DVB-IPDC end-to-end architecture combines heterogeneous broadcastand interactive networks
o DVB-IPDC phase 1 over; DVB-H is currently beingcommercially rolled out in various regions
o DVB-H is supported by Mobile DTV Alliance
o DVB-IPDC is well-suitedfor « Mobile IPTV »

CSF
o Converged Services Framework (CSF) coordinates services across different administrative domains from a user perspective

ITU-T IPTV Global Technical WorkshopSeoul, Korea, 12-13 October 2006
CSF Functional Elements
o Convergence Coordination Function (CCF): • Coordinates the multiple preferences, resources and
sessions created by each access and service network to affect a consistent convergence offering.
o Convergence Support Functions (xSF): • Network SF (NSF) - Interface to each AN’s session
controls• Edge SF (ESF) - Interface to each AN and ESF
subtending devices • Client SF (CLSF) - Interface to end user clients
o Convergence Policy Function (CPF):• provides policy management which is
implementation-independent
