IP Network
 Moving from several dedicated networks (silos) to converged multipurpose networks
 IP networks have different technical characteristics than old Broadcast networks (e.g.
two-way interactive)
 The resulting IPTV services are extensions to TV but also a competitor
 New distribution methods affect market situation and TV value-chain
 Regulation affects all of the above

Framework for IPTV
Set-top Box
Auxiliary Systems
Media Servers
IP Network
 Elements of IPTV, such as coding, are standardised
 [Fleury, 2005] reports a lack of holistic IPTV standardisation framework
 [Tadayoni and Sigurdsson, 2005] Empirical study indicates that operators see
IPTV standardisation as a barrier
 Standardisation bodies such as IETF and ITU-T are working on IPTV
standardisation
 Most current implementations are based on proprietary solutions

 Empirical Study Suggests
– Efficiency and marketing drives commercial IPTV towards managed
networks
– Alternative sources/content may be over Internet
– Networks Access Providers can use service differentiation to discriminate
