Radio Data System

The Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. It allows FM radio stations to transmit additional data alongside the audio signal, such as station identification, song titles, traffic updates, and program information. RDS enhances the listener experience by enabling features like automatic tuning, displaying station names on receivers, and providing real-time traffic alerts. Widely used in modern car radios and home receivers, RDS plays a key role in making FM radio more interactive and informative.
