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 signal recording and playback device, the transmission rate of input transport packets is identified. A recording mode, a rate at which data is to be recorded, is set on the basis of the identified transmission rate. Intra-frame or intra-field coded digital video data is extracted from the transport packets, and the extracted intra-frame or intra-field coded digital video data is reconstructed to generate special playback data. A recording format is generated such that the input transport packets and special playback data will be recorded at predefined positions on a track of a recording medium. The number of repetitions of the special playback data to be recorded on the recording medium or the recording format is varied depending on the recording mode. Because of the improvement in the recording rate of the fast playback data, the playback picture quality during fast playback can be improved.

摘要： A signal which is to be used in high-speed playback is recorded in a predetermined region of a track. An error correcting check code region for recording an error correcting check code is formed at a position adjacent to the predetermined region. In accordance with the usage, an error correcting check code for high-speed playback, an error correcting check code for normal playback, or predetermined fixed data is recorded in the error correcting check code region. In a digital VTR which records and plays back data at plural kinds of data rates, trick playback data are recorded so that a head scans a subcode area or a VAUX area in high-speed playback at a predetermined tape running speed in each record mode. An area for recording an error correcting check code is used as an area for, in addition to an error correcting check code for normal playback, recording an error correcting check code for trick playback, normal playback data, or trick playback data.
