ABSTRACT:
Digital video signal of one frame is converted to macro blocks which are arranged in a predetermined order in one rectangular block. The macro blocks are converted to synchronizing block data and are recorded in a predetermined number of tracks of a magnetic tape. In high speed reproducing operation, a tape running speed is selected to a reference speed at which scanning areas of the tracks of successive frames having the same track number are shifted in a direction every frame number, and video data which are on every other frame are arranged on the reproduced video image.
