ETSI TISPAN IPTV Overview TISPAN Release 2 introduced IPTV to the NGN architecture: Broadcast TV, Content on-Demand, Network-PVR TISPAN Release 3 adds new kinds of services by combining NGN features (voice, data, presence, messaging, community, IPTV) : User generated content User recommendations Personalized channel Personal service composition Content personalization Shared service control Ongoing work: CDN, P2P Targeted advertising Messaging Push CoD Advanced PVR IPTV Roaming / Mobility Media Synchronization CDN: Content Delivery Network P2P: Peer to Peer PVR: Personal Video Recorder 14

IPTV over NGN Blended services Triple Play bundle Context IntegratedIPTV IMS-based IPTV Integrating existing IPTV solutions within NGN Leveraging investments in IMS Context Blended services Communication Content Phone TV Internet Triple Play bundle Why IMS-based: Allows integration of IPTV flows into bundled service packages to expand market and increase customer interest Reuse well standardized IMS components to enforce IPTV control, e.g. registration & authentication, multi-user identity, session control, real-time billing, QoS, NASS/RACS. Enable enhanced and converged services (Caller ID on screen, personalized TV, chat on view, friends TV, …) Enables convergence, access agnostic of different type of access networks, service continuity across devices…

Content Delivery Network (CDN) TISPAN also defines CDN functional requirements, architecture and interaction with IPTV systems Content Delivery Network Service Provider Network CDN Controller Function IMS-based IPTV Cluster Controller Function Cluster Controller Function Integrated IPTV Note: this is the first global approach for standardizing a CDN ETSI TISPAN, which is working on IPTV standardisation is currently defining the Content Delivery network. On left hand side, service provider and home network have been defined for an IPTV service. On the right hand side, this is their current work: services requirements, functions, architecture and procedures for the CDN. So far, the work is led by telecom operators. Content Delivery Functions Home Network

TISPAN Study: Operator-managed P2P for IPTV No operator involvement Full operator involvement Degree of network operator involvement in P2P content delivery Pure “Over-The-Top” (OTT) Network-Based Access Control (NBAC) P2P-based operator content service Operator-internal P2P-based CDN Deep Packet Inspection (DPI) Peer for peer (P4P) Peer-to-Peer technology can be applied in many ways, with zero or however significant operator interaction. TISPAN is currently considering if operator-managed P2P communication could assist in efficient operations, by keeping a lot of content re-distribution at the edge of the network.
