Abstract

PURPOSE: To reproduce a stable picture by eliminating a pulsatory noise generated due to a dropout by providing a dropout inhibiting gate circuit between the sampling pulse circuit and sampling pulse generating circuit of a video disc player.
CONSTITUTION: In the time-axis corrector, a synchronising signal with its time axis corrected is found by phase-modulating a sampling pulse, obtained from a regenerated video signal from terminal 1 by sampling pulse generating circuit 4 consisting mainly of synchronous separator circuit 2, by a time-axis error obtained by time- axis error signal detection circuit and this signal is added to a video signal with the synchronizing signal removed previously. Between circuit 4 and circuit 11, dropout inhibiting gate circuit 6 and dropout detection circuit 5 are provided. Then, gate circuit 6 is operated by a detection pulse from circuit 5 to inhibit sampling pulses during a dropout period, thereby removing pulsatory noises generated by a dropout.
