  • Nowadays IPTV services are gaining attention from both providers and end users. There is a large effort toward 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. This article focuses on introducing layered 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, live mosaics, adaptive video quality based on device and/or network
    capabilities). 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.
