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.

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： In a digital signal playback device for playing back data from a recording medium on which intraframe, intrafield, interframe or interfield encoded digital video signals and digital audio signals input in the form of packets have been recorded transparently, and special playback data for special playback generated from said intraframe or intrafield encoded digital video signals has been recorded at predetermined positions, the special playback data is separated from a playback signal during special playback, and stored in a data storage circuit stores the separated special playback data. A still image slice data generator generates slice data with the motion vectors being 0 and prediction errors being 0 for all macroblocks in the slice. A data controller controls the still image slice generator such that the slice data from the still image slice generator is output for a predetermined number of frames after the special playback data of one frame or one field separated from the data storage means has been output. With the above arrangement, memory capacity is reduced, circuit size is reduced, and special playback can be realized without causing the ATV decoder to recognize the special playback mode.

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.

摘要： According to a first aspect of the invention, digital image data are recorded in the form of compressed codewords with check information and flags. The flags indicate codewords containing uncorrected errors. Each time the data are copied, error detection and correction are performed and the flags are updated to indicate any new uncorrectable errors that are detected. The flags can be used for error concealment, to avoid error miscorrection, and to permit the check information to be regenerated each time the data are copied. According to a second aspect of the invention, when image data are copied, the same check information is used to perform error detection and correction twice. Flags identifying uncorrected errors can be transferred from the first error-detecting-and-correcting process to the second.
