IMS based IPTV: ETSI TISPAN standards applied

This paper summarizes IMS based IPTV as defined in ETSI TISPAN Release 2 as well as the potential enhancements being added in Release 3 at the time of writing. After an introduction to the use cases and to TISPAN NGN standardization, the different aspects, such as Service Discovery, User Profiles and the underlying signaling concepts are discussed. Furthermore this paper provides links to other ongoing standardization work of ETSI TISPAN e.g. in the area of Content Delivery Networks, Content Distribution (ETSI MCD) as well as in the area of the evolution of Home Networks. This paper can be considered a guide to the IMS based IPTV as defined in ETSI TISPAN specifications of Releases 2 and 3, a solution that allows service providers to build their service offerings using standardized Network platforms.
