Abstract: An encoding controller (106) generates and outputs a current skip signal (SKi) to a switch circuit (108), and outputs a quantization parameter (Qp) for controlling a code amount after the encoding processing of a current VOP by an encoder (103) using a current scene change signal (SCi), to an encoder (106). The current scene change signal (SCi) is set on the basis of the current VOP, a previous scene change signal (SCi-1), and a previous skip signal (SKi-1).

Abstract: 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.

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.

Abstract: 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.

Abstract: 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.

For correcting errors by applying error correction codes in three directions of a recording direction, perpendicular direction, and direction of tracks, whether a burst error has occurred is checked, and an error-correction decoding algorithm is switched between one used when a burst error has occurred, and one used when no burst error has occurred.
