  • Apparatus having a field memory for reproducing video signals
    Patent number: 5130858
    Abstract: A video signal reproducing apparatus, such as a video disc player, equipped with a field memory for special reproduction such as still-picture reproduction. The video signal writing-reading period for the field memory is set to a value which is the color subcarrier period multiplied by an integer, is also the horizontal synchronizing period multiplied by an integer and is further approximate to one field period to the greatest possible extent, to thereby eliminate the discontinuity of video signals due to the track jumping action of the pickup.
