  • Patent number: 5548828
    Abstract: A Radio Data Systems (RDS) receiver has a decoder circuit to read RDS data from a broadcast transmission signal. From the RDS data, a control circuit determines a program of the received signal, a program category of the received signal, lists of programs and program categories of other stations, and a regional digit. The receiver has a controller to store a desired program category. The RDS data is used to control the receiver to perform several different functions. The receiver will interrupt reception of a signal, the category of which is different from a desired category and receive a signal that matches the desired category. The receiver will revert to a previous program when the category of the signal to which it switched no longer matches the desired category. The receiver will revert to the strongest signal having one of a specified set of regional digits. The receiver also permits the storage of a desired category using only an RDS key and at least one other key.
