The technology has a function of cascade data transfer This means that each regional transmitting center can serve as a intermediary link passing received broadcasting material further down the line Thus a complex network can be built including regional and sub regional broadcasting points For example the Dorozhnoye Radio network of Russia has its main center in Saint Petersburg a regional center with broadcasting point in Pskov and a network of sub regional broadcasting points throughout Pskov region of Russia DIGISPOT SYSTEM GMBH 5 1 3 Organizing automatic broadcasting network with delivery of main program via satellite channel Suppose that we have the signal of the main radio program on a satellite and can accept this signal in any point of relevant region Apart from that there are several transmitting centers in various cities and an office with a sales department and editorial in city N The program on the satellite can be both our own program lifted from the office based studio and a third party program broadcasted by means of a license In this situation the DDB technology allows automation of preparation sending and output of local commercial blocks on all regional transmitting centers The hardware and software configuration remains the same Regional DDB Automat software complex with Retransmission option or Regional 777 DDB Automat software complex on all regional broadcasting points and DIGISPOT II with
