摘要：<p>A block segmenting circuit block segments a digital video signal. A block encoding circuit encodes the block segmented data. A head (H) records the encoded data on a tape. A block segmenting circuit varies the start address of each block and detects an error between the original data and the decoded data at each start address. A cumulating circuit (36) cumulates the errors for a predetermined time period. A detecting circuit (39) detects the minimum value of the cumulated values. Thus, a block start address with the lowest error is determined. With a block construction defined by the start address, a block segmenting circuit perform block segmentation. <IMAGE></p>
