Digital video data recorded in D-1 format, wherein the video data is recorded in successive block units with each block unit being comprised of several segments recorded in plural tracks and with each segment including unit identifying data, is recovered by scanning the tracks with plural sets of reproducing heads (20) to reproduce plural segments concurrently from plural tracks. The unit identifying data in the segments reproduced by all of the reproducing heads in the plural sets are sensed to detect (21) when the unit identifying data in those segments includes common unit identification, thus determining that all of the segments of a preceding block unit have been reproduced from the record medium. That preceding block unit then can be supplied in its entirety to processing or display devices, such as a television monitor. |
