The Radio Data System (RDS) provides for a method of transmitting a low-bit rate digital signal using analog FM radio. It is intended for application to VHF/FM sound broadcasting transmitters that carry stereophonic (pilot-tone system) or monophonic sound broadcasts specified in ITU-R Recommendation BS.450–3. Radio Broadcast Data System (RBDS) was the official name used for the U.S. version of the RDS Standard, when it was first adopted in 1993 by the National Radio Systems Committee (NRSC) with revisions in 1998, 2005 and 2011. 1 The RDS Standard was originally adopted in 1982 by the European Broadcasting Union (EBU) for transmitting low bit rate (on the order of 1 kilobit per second) digital information to appropriate receivers using conventional FM radio broadcasts. The RDS Standard is now an International Electrotechnical Commission (IEC) standard; the current IEC version is 62106 Ed.3 (2015).
