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

12

ITU-T


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
