Abstract

PURPOSE:To simplify a circuit and to improve a detecting accuracy by executing the processing of a digital voice with a signal detected when a frequency- multiplexed recorded analog video signal is processed. CONSTITUTION:In a disk on a turntable 1, together with a digital video signal and a digital sound signal FM-modulated after they are digitized and coverted to a PCM code, an another new video signal FM-modulated in the condition of an analog signal is frequency-multiplexed and recorded. A video signal read from a disk and inputted to an FM demodulation circuit 6, after it is demodulated here, is outputted to an error detecting circuit 7 and a video signal processing circuit 10. The analog inputted to the circuit 10 is converted to a standard color TV signal, inputted to a HD.VD.DT detecting circuit 9, a DT signal (drop-out detecting signal) is detected, and then, the data are outputted to the circuit 7. By the DT signal, even when the leakage of the error detection occurs, the accuracy of the erroneous detection can be increased.
