Abstract
A digital time base corrector in which a memory for correction of a time base is commonly used as a memory for correction of a drop-out and a signal process to a video signal which is replaced by a drop-out compensation is made unnecessary. The corrector has an image memory having a capacity to store the digital video signal by only two horizontal scan periods. When a drop-out occurs in the reproduction video signal, the writing operation into the image memory is inhibited. In the portion in which the drop-out occurred, the video data before about 2 H is read out in place of such a portion and the drop-out compensation is executed. Therefore, the drop-out portion is replaced by the video data of the same phase.
