Collective Service Segment

The Collective Service Segment (CSS) contains all those components/functions providing services to a community of users (i.e., the residents of a multi-storey building or the inhabitants of a small country village) connected to a bi-directional satellite terminal. Since the satellite media is particularly suitable for  multi-casting applications, local storage is a key function of the CSS to allow high quality multimedia services and optimum use of the satellite frequency resources. In case of unicasting, the satellite segment provides ACM functionalities (using the DVB-S2 standard) in order to maximise the satellite capacity throughput .
