ABSTRACT:
A digital VTR for magnetically recording and replaying a bit stream, includes a detector, an extractor, a mode designator, and an output unit. The detector detects intra-picture data in the bit stream being replayed from tracks in a magnetic medium. The extractor extracts the intra-picture data from the bit stream based on output from the detector. The mode designator designates one of a normal replay and a slow replay as a replay mode. The slow replay is replay performed at a speed slower than normal replay. The output unit stores the extracted intra-picture data, and outputs only the extracted intra-picture data as replay picture data when the slow replay mode is designated.
