data radio channel (DARC)

Data Radio Channel (DARC) is a method used in the USA for broadcast transmission of data in FM broadcasting, comparable to the Radio Data System( RDS).

With DARC, as with Radiotext, in addition to the broadcast transmission of radio data, data about the transmitter, interbrets or other data can be transmitted. DARC uses its own separate data channel over which text and graphics can be transmitted. The DARC system is dealt with by the European Telecommunications Standards Institute( ETSI) , the European Broadcasting Union( EBU) and the Comité Européen de Normalisation Electrotechnique( CENELEC).
