Zusammenfassung:PURPOSE:To surely recognize a same program. CONSTITUTION:When a zero cross point is detected from a demodulation signal from a main tuner section A and a sub tuner section B, while a noise component is detected by a noise detection section 15, the detection of the zero cross point of a same program identification circuit 10 is stopped. Thus, even when external noise is generated, since the detection of the zero cross point is ensured, a same program is surely identified.
