摘要： In a digital VTR which receives at least a digital video signal input in the form of a bit stream, and which records the bit stream according to a transparent recording method, header information is extracted from the bit stream and modified. Intra-coded block components are also detected and extracted from the bit stream, and one track is configured with an area for recording the input bit stream and an area for recording fast playback HP data. Extracted as the intra-coded block components are a predefined number of orthogonal transform coefficients, and the fast playback HP data is configured without appending EOB codes to the intra-coding block components. Alternatively, EOB codes are appended except that the shortest EOB code from a plurality of code maps is used. The digital VTR also records more than one fast playback signal in predefined regions on predefined tracks such that a first playback signal is recorded in an area at one location on one track, while a second playback signal is recorded in a plurality of areas on a track adjacent thereto.

摘要： In a digital VTR having a certain recording bit rate, within a range not higher than a remaining data rate after recording the bit stream, first HP data D1 is recorded in first specific regions, and second HP data D2 is recorded in second specific regions in specific tracks. In middle-speed and high-speed fast replay, the magnetic tape is transported continuously at a middle-speed or high-speed higher than the standard speed for normal replay, and the first HP data D1 is used in common, and at a low-speed fast replay of about twice the normal speed, the speed of the magnetic tape is alternated between a speed near the standard speed for normal replay, and a speed near the low-speed fast, and at the speed near the standard speed, the second HP data disposed in the second specific regions in the specific tracks and the first HP data disposed in the first specific regions in the specific tracks are both replayed.

摘要： 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.
