Enabling Layered Video Coding for IMS-Based IPTV Home Services
MetadatosMostrar el registro completo del ítem
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 nextgeneration 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.
