Abstract
For the tuning of a broadcast radio receiver to a transmitter of a certain type of program using RDS information firstly the broadcast radio receiver is tuned to any convenient transmitter, which is transmitting a program, which is in accordance with the wishes of the listener. The PTY information retrieved from the RDS data of such transmitter is stored by operation of an associated control element in order to set a filter, whose filter condition is the agreement with such PTY information. For the following tuning of the broadcast radio receiver to another transmitter, as for example by means of a search sweep, such transmitter is only considered to be suitable for reception if it fulfills the filter condition.

A method of tuning a broadcast radio receiver to a transmitter station, transmitting a particular type of program using Radio Data System (RDS) information, comprising the steps of:
- tuning the broadcast radio receiver to any transmitter station broadcasting a program which meets the preferences of the user,
- extracting the program type information (PTY) from the RDS information which is broadcast by the tuned-in transmitter,
- operating a filter activation key to set a filter condition corresponding to the program type of the tuned-in transmitter station,
- triggering an automatic transmitter station search,
- comparing the PTY information of each transmitter station found in the station search with PTY information of the filter condition set, continuing station search until a particular transmitter station with matching PTY information is found;
- and
- stopping station search on a particular transmitter station only when the compared PTY information match.
