Next Generation IPTV services for an extended IMS architecture

Currently there is a strong discussion throughout the industry and all relevant standard development organizations (SDO) like the ITU-T and ETSI TISPAN how next generation IPTV services could incorporate with the developments from the TISPAN NGN Release 2 architecture. Several approaches have already been introduced struggling with the need for an integrated solution with the core IMS network or the development of a separated subsystem for next generation IPTV services. The main focus for the integrated solution lies on the difficulties in using the session initiation protocol (SIP) or SIP in combination with the real time streaming protocol (RTSP) for both the signaling and media control including so called trick functions that allow to manipulate media delivery by e.g. pausing and fast forwarding the content. This paper demonstrates fundamental scenarios and requirements towards a cooperative service delivery platform for the provisioning of IPTV services over IMS enabled next generation networks. As a result of that work a generic IMS-based cooperative service delivery platform is introduced
