Abstract
An RDS or RDBS radio broadcast receiver, utilizing a microcontroller and a serial communication bus, receives a list of alternative frequencies to allow the receiver to switch to an alternative frequency when the quality of the main radio broadcast signal deteriorates. Therefore the quality of the alternative frequency transmissions has to be updated from time to time. To avoid time delays caused by the relatively slow serial communication bus, the tuning section includes further controller for performing the alternative frequency updates.
