PURPOSE:To prevent or reduce beat disturbance due to the interference with other signals by deviating a tuning frequency in a direction opposite to a broadcast signal to the broadcast signal to be received. CONSTITUTION:A reception means 1 receives a broadcast signal formed by FM-modulating a prescribed carrier by a signal where the FM sound having the carrier at the upper frequency band of the video signal is multiplexed. A tuning means 2 controls the tuning frequency to receive a prescribed broadcast signal. A tuning control means 3 controls the tuning means 2 to deviate slightly the tuning frequency from the tuning frequency corresponding to the prescribed broadcast signal. An AFT operation control means 4 controls the AFT operation in the tuning means 2. When the tuning means 3 deviates slightly the tuning frequency, since the AFT operation of the turning means 2 is inhibited by the AFT operation control means 4, the state deviating the tuning frequency is kept as it is.
