ABSTRACT:
An automatic tuning system for automatically compensating for a tuning error of a TV receiver to maintain a satisfactory receiving state which detects whether an error in a video program system signal is generated due to an abnormal receiving state, changes the frequency of the oscillating signal, which is mixed with the received broadcasting signal, by varying tuning data if an error is detected, thereby automatically performing the tuning operation so as to maintain the satisfactory receiving state of the RF broadcasting signal.
