PURPOSE:To improve the function of a receiver by providing a controller which processes the output of a coincidence detecting circuit and switching a music source to another by the operation of a tuning knob of the receiver when an undesired program is reproduced. CONSTITUTION:The demodulated signal demodulated by a tuner 2 of the receiver is processed by a program discriminating signal detecting circuit 3, a coincidence detecting circuit 4, etc. to detect the coincidence between start and end patterns of desired program information and preliminarily set start and end code patterns. This detected coincidence signal is applied to a controller 5 through an OR circuit 6, and a key matrix 7 is connected to this controller 5. The output of the controller 5 is applied to a program discriminating reception preference control circuit 8, a frequency division ratio setting counter 13, a latch circuit 15, and an exclusive OR circuit 16, and the output processed by circuits 15 and 16 is inputted to the other input of the circuit 6. The output of the counter 13 is applied to the tuner 2 through a PLL14, and another music is heard by the operation of the tuning knob. |
