Filed: 1990-07-12
Abstract: PURPOSE:To distinctly discriminate drop-out by adding a gate circuit, a switching circuit, and an oscillating circuit to a home VTR to properly set a drop-out period. CONSTITUTION:The frequency modulated signal (FM signal) of the luminance signal reproduced by a video head 1 is amplified by a head amplifier 2 and is led to an FM demodulating circuit 3 and a drop-out detecting circuit 4. The drop-out detecting circuit 4 detects the amplitude of the FM signal; and when the detection output has the amplitude about 20dB shorter than the normal amplitude, the circuit 4 outputs the output signal indicating the occurrence of drop-out. A synchronizing signal separating circuit 7 separates a synchronizing signal from the luminance signal to take out it, and it is led to an AFC circuit 8 to generate a stable synchronizing signal. Drop-out in a period other than the synchronizing signal period is selected by a gate circuit 9 in accordance with this stable synchronizing signal and the output signal of the drop-out detecting circuit 4, and the demodulated video signal and the output of an oscillator 11 are switched by the output of the gate circuit 9. Thus, the occurrence of drop-out is distinctly discriminated.
