ABSTRACT:
In a receiving device of the invention used in high-definition television, a frequency information storage section stores error information of a frequency error of a signal output from an oscillator. A control unit controls the oscillator based on the error information stored in the frequency information storage section. In a simple configuration, it is, therefore, possible to shift, the frequency in a direction of tuning by a tuner, to thereby output the signal with an appropriate frequency from the oscillator without being influenced by an accuracy of the oscillator, thus to demodulate the received signal accurately. Accordingly, it can be avoided such a problem that no pilot signal is present in an IF signal within a predetermined band width filtered by a SAW filter or that the pilot signal, even if present, cannot be received.
