Abstract

The enhanced features and increased efficiency of the second-generation digital satellite broadcast technology (DVB-S.2) strengthen the role of satellite networks as carriers of "triple-play" services (television/telephony/Internet access). Interactivity can be provided with appropriate satellite interaction technologies, such as DVB-RCS. This paper presents the concept of the EU-funded IMOSAN project which aims to provide triple-play services over an interactive DVB-S.2/DVB-RCS network, achieving at the same time optimum bandwidth allocation. This is realised via a multi-layer resource allocation mechanism, operating at real time and spanning across the physical, network and application layers of the platform.
