ABSTRACT:
In accordance with the operation of an operating section 14, a control section 12 performs a reception control operation and demodulates a signal passing through a band pass filter 7 for extracting a multiplex signal using a multiplex signal demodulating section 8 when receiving a broadcast signal. A block synchronization circuit 16 of a synchronization circuit 9 carries out block synchronization processing on the demodulated signal. When block synchronization is established, a synchronization determination signal is supplied to a detecting section DET and the detecting section DET determines that a broadcasting station whose radio waves are currently being received is a multiplex broadcasting station.
