This project deals with the development of software to receive, decode, and display RDS (Radio Data System) data transmitted by analog radio stations. Data includes station name, time, radio text, or traffic messages (TMC). As the latter is used by car navigation systems, RDS will exist for several more years, despite the growing importance of digital radio.
The Radio Data System Daemon is a daemon that reads raw RDS data from one or more input sources, decodes it, and serves the results to clients that can connect via TCP/IP or a unix domain socket.
