+ " A DAB multiplex configuration is composed of one ensemble. An ensemble\n"
+ " is the entity that receivers tune to and process. An ensemble contains\n"
+ " several services. A service is the listener-selectable output. Each\n"

+ " while a data primary component define a data service. Service can con-\n"
+ " tain additional components which are called secondary components. Maxi-\n"
+ " mum total number of components is 12 for program services and 11 for\n"
+ " data services. A service component is a link to one subchannel (of Fast\n"
+ " Information Data Channel). A subchannel is the physical space used\n"
+ " within the common interleaved frame.\n"
