The RDS (Radio Data System) is a digital information system developed by the EBU (European
Broadcast Union). Piggy-backed on normal FM broadcasts, RDS offers a variety of information
services and automatic retuning functions for RDS-compatible car stereos.
In 1988, RDS became available in the United Kingdom, France, West Germany, Ireland and Sweden.
Test transmissions are being conducted in many other european countries. It is expected that RDS
will be available in most western european countries in the near future.
