Section 2 presents a generic IPTV architecture, while section 3 describes standardization efforts such as TISPAN, OIPF, ITU-T and ATIS specifications for the next generation IPTV.
It is noteworthy that ETSI TISPAN specifies (next-generation network) NGN-based IPTV as "Multimedia system that provides IPTV services over the NGN architecture and may be implemented as an integrated subsystem with the NGN (NGN integrated IPTV) or may use the IMS subsystem (IMS-based IPTV) in the NGN".
ETSI TISPAN (European Telecommunications Standards Institute, Telecommunications and Internet converged Services and Protocols for Advanced Networking) is also conducting a relevant work on IPTV standardization.
Release 2 of specifications of TISPAN NGN adds new features and services to the NGN such as IPTV.
TISPAN release 2 defines three main services for the IMS-based IPTV system: (a) Broadcast TV; (b) Content on Demand (COD); and (c) Network-Personal Video Recorder (N-PVR).
Figure 4 shows an overview of the functional architecture defined by TISPAN for the IMS-based IPTV system in release 3 [13].
ETSI TISPAN specification for the IMS-based IPTV system and the NGN integrated IPTV system can be found in [12] and [13], respectively.
