Due to the lack of quality guarantees, it's very difficult to deploy IPTV services in the current internet, especially in a NGN network, the core IMS framework interconnects different access networks which have differing amounts of bandwidth available and varying client terminals. The ETSI TISPAN standards allow adaptation multimedia content by transcoding, however, it is computationally intensive. This paper focuses on introducing scalable video coding into TISPAN IMS-based IPTV architecture, allowing cost-effective efficient solutions both for residential users and providers (e.g., flexible support of heterogeneous devices, adaptive video quality based on device and/or network capabilities).
