Abstract
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.
