User Requirements
ITU-T
o Key user requirements for ITV include
• TV content choice in fixed and mobile
formats
• interactive applications, inc. games, ecommerce, etc
• ubiquitous ‘converged service’ availability –
home, office, vehicle and on-the-move
• variety of fixed and mobile devices
• access from many network types

Convergence
Quad-Play
o Examples of Quad-Play service scenarios:
• alliance of wireless operator with cable MSO
• alliance of wireless operator with telco
• combined fixed-mobile operator
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

CSF Functional Elements
ITU-T
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
