Enabling Layered Video Coding for IMS-Based IPTV Home Services


Iván Vidal, Jaime García-Reinoso, Francisco Valera, Alex Bikfalvi


Nowadays IPTV services are gaining attention both from providers and end-users. There is a large effort towards the integration of these services into emerging Next Generation Network architectures. In particular, one of the most relevant solutions is being proposed by ETSI-TISPAN and is based on the IP Multimedia Subsystem (IMS). This paper focuses on introducing layered video coding into TISPAN IMS-based IPTV architecture, this way allowing cost-effective efficient solutions both for residential users and providers (e.g. flexible support of heterogeneous devices, live mosaics, adaptive video quality based on device and/or network capabilities, etc.). The advantages of using layered video coding in the TISPAN IPTV solution are analyzed and illustrated with a set of use cases. Furthermore, this solution has been integrated into a multimedia testbed in order to validate the presented proposal.
