Title: Recording and reproducing method for video signal
Inventor: CHIBA MITSUO
IPC: H04N5/92
Filed: 1985-10-24
Abstract: PURPOSE:To reduce the deterioration in the picture quality due to a jitter by dividing one horizontal scanning period of an input video signal into plurals and inserting a synchronizing signal every this division to record and reproduce. CONSTITUTION:A clock generating circuit 4 forms various clocks of a frequency of integer times as large as the inputted synchronizing signal. An input video signal S2 is written in a RAM5, the one horizontal scanning period is alternately dispersed into two channels and the one horizontal scanning period is divided into two parts having duplicate parts and extended under a time base to have S3 and S4 as shown in a figure. In these signals S3 and S4, spaces Tp are provided. To switches 6 and 7, a signal corresponding to a negative polarity pulse is supplied from a ROM8 and switched by the clock from the circuit 4. Therefore, switches S5 and S6 are brought into the state as shown in the figure and the negative polarity pulse is inserted every division part. Reproducing clock generating circuits 25 and 27 respectively form clock pulses integer times as large as the negative polarity pulse inserted during recording from the negative polarity pulse. During reproducing, a control signal is formed from this signal to correct a time base fluctuation of a recording and reproducing signal and synthesize the divided signals. In this manner, since the negative polarity pulse is inserted every divided part, the period of the negative polarity pulse during reproducing is shortened. Accordingly, the jitter of the video signal can be reduced.
