Abstract

PURPOSE: To obtain a reproduced picture of high quality by removing a modulation noise of an AM component with the jitters in reproduction mode, by previously recording a jitter detection signal in parallel to signal recording.
CONSTITUTION: An input video signal after Hadamard's conversion 2 is FM-modulated 31W38 and recorded, channel by channel, by heads 51W58 through switches 41W48. At this time, the fixed frequency of oscillator 11 is recorded for jitter detection on a tape by head 13. In reproduction mode, signals from respective heads are demodulated by demodulators 61W68, and 18 by way of switches 41W48, and 12 and a jitter component extracted by demodulator 18 is inverted 19 and mixed 71W 78 into each demodulated signal. Consequently, jitter components included in reproduced signals of respective channels are canceled and the original signal can be obtained through time-axis correction units 81W88 and Hadamard power inverter 9.
