Abstract
PURPOSE: To make it possible to record and reproduce correctly a signal with a picture and sound information mixed by recording a video format signal mixed with a discrimination signal from a discrimination signal generating circuit and then by separating and reproducing the discrimination signal from a demodulated signal at a reproduction side.
CONSTITUTION: A video format signal applied to input terminal 1 is separated 2 to send a synchronizing signal and fly-back signal to timing detection circuit 3, and the video format signal is also supplied to a synthesizer circuit. In accordance with the obtained synchronizing signal or blanking signal, circuit 3 generate timing pulses and supplies them to discrimination signal generating circuit 5, which generates a discrimination signal equivalent to a number or character corresponding to a signal from setting circuit 6, and the video format signal and discrimination signal are mixed at the timing of circuit 3 and recorded while a reproducing unit separates the discrimination signal from the demodulated signal and then records it. Consequently, the video format signal with the picture and sound information mixed can correctly be recorded and reproduced by using the discrimination signal.
