Filed: 1980-12-26
Abstract: PURPOSE:To exactly receive a desired channel, by utilizing the fact that a synchronizing signal cannot be detected, in case a video carrier wave has been received by a higher local oscillation frequency than a local oscillation frequency by which it has been received regularly. CONSTITUTION:A control part 33 varies a local oscillation frequency fOSC within a correction range, and detects a signal. Also, in a synchronizing signal detecting circuit 32 and an automatic frequency control (AFT) circuit 31, the control part 33 execute AFT correctin in accordance with an AFT control signal only in case both a synchronizing signal and an AFT signal have been detected in the respective circuits, and corrects the local oscillation frequency within a prescribed area. Subsequently, when the correction ends, the AFT operation is stopped, a frequency dividing ratio data of a PLL circuit 13 in that case is stored in an RAM331 of a control part 12. Subsequently, a control part 13 transfers the frequency dividing ratio data stored before to the circuit 13 in case the synchronizing signal cannot be detected before the frequency fOSC is raised up to about 1MHz. On the other hand, in case the synchronizing signal is detected, the AFT lead-in operation is started again by the circuit 31.
