摘要： A digital video signal recording and reproducing apparatus and method wherein a basic block is constituted by a plurality of pixels of video signals. A picture data compressing unit effects data compression of the video signals so that a compression data quantity after data compression becomes a constant with respect to a compression block constituted by a plurality of the basic blocks, and the compressed data o the video signals are recorded on a data recording medium. A compression block setting sets a number of the basic blocks to constitute the compression block in response to different operation modes of the digital video signal recording and reproducing apparatus which are different in at least one of resolution of the video signals, recording time and data compression system, and controls the picture data compressing unit so that the number of the compression blocks of the video signals recorded on one track of the data recording medium after data compression by the picture data compressing unit becomes M in a first operation mode, where M is a positive integer, and the number of the compression blocks becomes a positive integer in each of the other operation modes.

摘要： A digital processing unit for converting a digital picture signal into data by blocks and for correction encoding a variable-length encoded signal. This digital processing unit includes a digital data compressing section for dividing a picture signal into a plurality of number of blocks, and compressingly outputting digital data of this picture signal based on a processing unit of one or a few blocks, a buffer section for sequentially storing the digital data, and an error correction encoding section for sequentially reading the digital data from this buffer section, and structuring an inner code for each inner block structured by this digital data and structuring an outer code for each predetermined unit of inner blocks, to thereby structure two-dimensional error correction code blocks, to output an error correction code signal. Further, the error correction encoding section has the length of the digital data of the picture signal included in the inner code set to be equal to or larger than a mean code length of predetermined compressed blocks.

摘要： A digital video tape recorder ("VTR") that selects data useful for generating images during trick playback operation and records the data in trick play tape segments arranged on a tape to form fast scan tracks and multi-speed playback tracks. Each fast scan track comprises trick play tape segments located on a diagonal, relative to the length of the tape, of the same angle as the angle at which the heads of a VTR are expected to pass over the tape during trick play operation at a specific speed and direction of operation. Each multi-speed playback track comprises a plurality of trick play tape segments arranged parallel to the length of the tape. Data which is used for at least one mode of trick play operation is recorded in each trick play tape segment. Each fast scan track and multi-speed track crosses multiple normal play tracks. During playback at a wide variety of speeds and directions, the heads pass over enough trick play segments of the multi-speed playback track to generate recognizable images during trick play operation. Data is recorded in each trick play segment in a manner that optimizes the amount of data that can be routinely recovered during trick playback operation despite tracking errors.

摘要： Methods of operating a digital video recording and playback device to identify trick play data, e.g., data that is intended for use during trick play modes of video playback device operation such as fast forward and reverse, by recording headers containing specific trick play information along with the trick play data are described. In one embodiment, the recording of headers which identify data as data intended for use during trick play as opposed to normal play operation is described. In addition to identifying data recorded data as normal play or trick play data headers associated with recorded data may identify the speed and direction of video tape recorder operation during which the specific data associated with the header is intended to be displayed at. When a data block includes data packets, a header may be used to identify various ones of the data packets as being for use during one mode of trick play operation, e.g., a first fast forward speed of operation, and other packets in the same data block as being for use during a second mode of trick play operation.

摘要： Methods of operating a digital video recording and playback device, such as a video tape recorder, to arrange trick play data into one or more groups, to generate error correction bits for each group of trick play data, e.g., a group of trick play data blocks, and to correct the data after being read back using the error correction bits is disclosed. The trick play data blocks are made to be smaller than normal play data blocks with multiple trick play data blocks being equal in size to a single normal play data block. By making a group of trick play data blocks equal in size to a single normal play data block, the group of trick play data blocks may be processed as a unit by the same error correction circuitry and in the same manner used to process individual normal play data blocks. In accordance with one embodiment, the error correction bits for a group of trick play data blocks are calculated treating the data in the group of trick play data blocks as a single unit. The error correction bits are appended to the last data block in the group of trick play data blocks. During trick play operation the trick play data blocks are read back and combined according to trick play data groups. Each group of trick play blocks is then processed using the same error correction circuitry used to process a normal play data block.

摘要： Digital video tape recorder ("VTR") and servo circuit for supporting the display of images during trick play VTR operation. The digital VTR, in one embodiment, having a single pair of heads of alternating azimuths located on a head cylinder one track width apart. The digital VTR records data that can be used to generate images during trick play tape speeds and directions of operation in fast scan tracks defined by the paths the single pair of heads trace over the tape during trick play operation. Each fast scan track crosses multiple normal play tracks. Sync blocks and track identification information are recorded on the tape along with video data. To align the heads with the appropriate fast scan track during trick play operation, a lookup table containing information on the pattern of fast scan tracks recorded on the tape is used. The information stored in the look-up table is compared to sync block number and track number information recorded on the tape to determine haw much the position of the tape must be adjusted to align the heads with the prerecorded fast scan tracks on the tape for the any selected speed and direction of digital video tape recorder operation.
