When a general broadcast other than a text broadcast is received or when video equipment is reproduced, the switching circuit 23 is closed to the (b) side, and the video signal is supplied to the synchronization signal detection circuit 14 via the switching circuit 13 and is detected by the detected synchronization signal. Is output to the deflection circuit. The synchronizing signal detection circuit 11 detects a synchronizing signal from a video signal as in the conventional case. The synchronization signal detection circuit 16 detects a synchronization signal from the synchronization signal after the detection of the synchronization signal. here,
An interest stop signal for stopping interlaced scanning to prevent character flickering when receiving teletext is supplied from the teletext demodulation circuit 12 to the deflection circuit. The switch circuit 17 is configured to be opened by an interface stop signal from the character signal demodulation circuit 12 and is closed when a general broadcast other than the text broadcast is received, so that the detection signal from the synchronization signal detection circuit 11 and the synchronization signal detection circuit 16 Are supplied to the discrimination signal generation circuit 15. The discrimination signal generation circuit 15 is configured by a switch circuit that opens and closes according to each detection signal, and closes when a synchronization signal is detected and a detection signal is supplied. Therefore, only when no detection signal is supplied from both the synchronization signal detection circuit 11 and the signal synchronization signal detection circuit 16, a determination signal indicating that there is no synchronization signal is output. As a result, the conventional synchronous signal detecting circuit 11 is supplemented by the synchronous signal detecting circuit 16 after detecting the synchronous signal, and the discrimination sensitivity can be improved.

When demodulating a character signal, the switching circuit 13
Is closed on the teletext demodulation circuit 12 side (a), the text signal output from the teletext demodulation circuit 12 is supplied to a synchronization signal detection circuit 14, and the detected synchronization signal is output to the deflection circuit. Since the teletext demodulation circuit 12 has a memory function, a text signal is output irrespective of the presence or absence of a video signal, and the synchronizing signal detection circuit 16 after detecting the synchronizing signal always has the synchronizing signal when receiving the teletext. Synchronous signal detection similar to the conventional one cannot be performed. Here, the supply of the detection signal from the synchronization signal detection circuit 16 to the discrimination signal generation circuit 15 is stopped by the switch circuit 17 configured to be opened by the interface stop signal from the character signal demodulation circuit 12. Therefore, the function similar to the conventional function can be maintained at the time of receiving the text broadcast. In the present embodiment, the detection signal of the synchronization signal detection circuit after the detection of the synchronization signal is opened by the switch circuit. However, the supply of the synchronization signal to the synchronization signal detection circuit may be stopped.
