The RDS (Radio Data System) as a Transmission Way of Information for Automotive Vehicles

Real-time information, standardized and interacting with radio broadcasting listeners during the time they spend driving their cars, could be extremely interesting and useful whether it offers public concerned information and make feasible the complete application of the system (hardware and software) it is based on. The RDS (Radio Data System) standard, which modulation characteristic is based on the concept its data signals are carried on a subcarrier which is added to the stereo multiplex signal at the stereo encoder, make feasible this benefits with extremely low cost, for the listener and even for the broadcaster.

Being applied in Europe for more than 15 years, the RDS offers features that improve the operation of the receiver and take advantage of the architecture available in some vehicles through remote actuation of many parts of the car. All this features has been superficially used in Brazil, due to the lack of information to the broadcasters and even the existence of a standard focused on Brazilian requirements.
