RDS was inspired by the development of the Autofahrer-Rundfunk-Informationssystem (ARI) in Germany by the Institut für Rundfunktechnik (IRT) and the radio manufacturer Blaupunkt.ARI used a 57-kHz subcarrier to indicate the presence of traffic information in an FM radio broadcast. The EBU Technical Committee launched a project at its 1974 Paris meet...
The following information fields are normally contained in the RDS data: AF (alternative frequencieslist) 1. This provides the receiver with a list of frequencies that allows a receiver to re-tune to a different frequency providing the same stationwhen the first signal becomes too weak (e.g., when moving out of range). Before performing the switch,...
As far as implementation is concerned, most car stereos will support at least AF, EON, REG, PS and TA/TP. 1. More expensive car stereos will offer TMC, RT and / or PTY, perhaps with "NEWS" override. 2. Home systems, especially hi-fi receivers, will mainly support functions like PS, RT and PTY. There are a growing number of RDS implementations in po...
The RDS sub-carrier at 57 kHz occupies ±2 kHz of the composite spectrum which in theory keeps it above the upper cutoff of the stereo subcarrier at 53 kHz. However the 53 kHz cutoff is entirely dependent on the performance of the 15 kHz low pass filters used before the stereo encoder. In older equipment, these filters were only designed to protect ...
The following table lists the RDS and RBDS (North American) program type (PTY) codes and their meanings: The PTY codes have undergone several expansions. The first RDS standard only defined 0–15 and 31. The later RBDS standard implemented in the U.S. assigned the same meanings to codes 0, 1 and 31, but made no attempt to match the rest of the origi...
The RDS standard as specified in EN 50067:1998is separated into these sections according to the OSI model. (The network and transport layers are excluded, as this is a unidirectional broadcast standard.) 1. Data channel(Physical layer) 2. Baseband coding(Data-link layer) 3. Message format(Session and presentation layer)
The following three images illustrate how RDS can be used on an FM radio station; the latter two were taken when the radio was tuned to Nottingham radio station Trent FM. All the images are of the display on the SonyXDR-S1 DAB/FM/MW/LW portable radio.
Companies such as ST Microelectronics, Silicon Labs in Austin, Texas and NXP Semiconductors (formerly Philips) offer single-chip solutions that are found in these devices.

System information allows navigation and access of the channels within the DTV transport stream, and program data provide the information necessary for efficient browsing and event selection.
Making digital and interactive television work depends up on the ATSC's new PSIP standard. This book, written by one of the standard's primary architects, annotates and explains the complex standard document, breaking it down into practical, usable checklists and methods for broadcast, cable, satellite, and product design.
The Program and System Information Protocol (PSIP) is the MPEG (a video and audio industry group) and privately defined program-specific information originally defined by General Instrument for the DigiCipher 2 system and later extended for the ATSC digital television system for carrying metadata about each channel in the broadcast MPEG transport stream of a television station and for ...
PSIP also supersedes the A/55 and A/56 protocol methods of delivering program guide information (which the ATSC has deleted). TV Guide On Screen is a different, proprietary system provided by datacasting on a single station, while PSIP is required, at least in the United States, to be sent by every digital television station.
