Because of its software based architecture, many typical DAB +services can be generated and multiplexed on a single PC platform with live or +pre-recorded sources. + +A DAB multiplex configuration is composed of one ensemble. An ensemble is the +entity that receivers tune to and process. An ensemble contains several +services. A service is the listener-selectable output. Each service contains +one mandatory service component which is called primary component. An audio +primary component define a program service while a data primary component +define a data service. Service can contain additional components which are +called secondary components. Maximum total number of components is 12 for +program services and 11 for data services. A service component is a link to one +subchannel (or Fast Information Data Channel). A subchannel is the physical +space used within the common interleaved frame. + + __________________________________________________ + ENSEMBLE | ODR-Ensemble | + |__________________________________________________| + | | | + | | | + _______V______ _______V______ _______V______ + SERVICES | ODR-Service1 | | ODR-Service2 | | ODR-Service3 | + |______________| |______________| |______________| + | | | | |______ | + | | | | | | + __V__ __V__ __V__ __V__ __V__ __V__ + SERVICE | SC1 | | SC2 | | SC3 | | SC4 | | SC5 | | SC6 | + COMPONENTS |_____| |_____| |_____| |_____| |_____| |_____| + | | _____| | | ____| + | | | | | | + _________________ __V________V__V______________V________V___V_______ + | MCI | SI | FIDC | | SubCh1 | SubCh9 | ... | SubCh3 | SubCh60 | ... | + |_____|____|______| |________|________|_______|________|_________|_____| + Fast Information Ch.
