ABSTRACT:
A receiver for receiving a broadcast in which data indicating a broadcast station name has been multiplexed to a main signal includes: a receiving circuit constructed in a frequency synthesizer mode; a memory in which a group of frequency data for selecting the broadcast in the receiving circuit, and data on the broadcast station name is registered; a circuit for taking out the data from a signal received by the receiving circuit; a scanner for allowing the receiving circuit to scan the broadcasting zone for the broadcast; and a detector for detecting the received broadcast at the time of the scanning, when the detector has detected the received broadcast during the scanning, the group of the frequency data which has been registered before the start of the scanning, and the data on the broadcast station name is shifted to the data area in the memory, and one group of the frequency data indicating the frequency thus detected, and the data on the broadcast station name for the received broadcast is registered in the data area in the memory which has become empty by the shift.
