Abstract

In an apparatus for multi-segment recording/reproducing of a compressed digital video signal, a reproduced position within a group unit of the video signal is detected by a reproduced position detector in its reproducing state. A relative position detector detects and stores a phase difference of the reproduced position and a position indicated by a reference signal synchronized with the input video signal. A delay time adjuster adjusts a delay time of the compressed video signal according to this phase difference. A head is changed over from its reproducing state to its recording state by a switch so as to record the compressed video signal delayed by the delay time adjuster on a recording medium.
