Abstract: An apparatus and method for controlling recording and reproduction in a video cassette tape recorder are disclosed. The apparatus is capable of, in a recording mode, separating specific data for speed-varied reproduction from compressed digital video signals, recording them on designated tracks, recording position information of the designated tracks on a control track by an index head or recording position information of recording position-synchronized blocks at the starting portions of the designated tracks recorded with the specific data, and in a speed-varied reproduction mode, controlling a capstan servo speed so as to maintain the travel of a magnetic tape at a normal speed and periodically or non-periodically accelerate or decelerate it where specific data for varied-speed have been recorded periodically or non-periodically on predetermined portions of tracks, thereby making heads travel repeatedly at the normal speed and the high speed and thereby detect continuously the specific tracks for varied-speed. A repeatability of reproduced video at a varied speed is obtained without any deterioration in picture quality, because of recording of the specific data for speed-varied reproduction and the continuous detection of the specific data in the speed-varied reproduction.

Abstract: Disclosed is a recording/reproducing apparatus in which a rotary head records digital data in tracks inclined to the lengthwise direction of a magnetic tape and reproduces the digital data recorded in the inclined tracks. In a reproducing system (20), the capstan-servo operation unit (71) locks the phase in ±24-times fast reproduction so that the rotary head may trace and reproduction search data. That is, the phase is locked at an inclined track of a specified track number. It is then determined whether the search data has been detected. If the search data is not acquired, the magnetic tape is fed in a prescribed direction. The phase at the next error-correction block is thereby locked. This process is repeated twice at the position remotest from a target position. Then, the phase is locked when the search data is acquired.

Abstract: It is an object of the present invention to provide a recording apparatus and a reproducing apparatus which change a picture compression rate depending upon a picture quality of a source which a user desires to retain, thereby a tape storage space being secured. A video-data compression rate N used by a 1:N video-data compression encoder 3 and a 1:N video-data compression decoder 6 is changed depending upon a picture quality set by a device 5 for setting a picture quality that a user desires. A tape travel speed of an archive VTR 4 is changed in response to the picture compression rate. Thus, an amount of a tape travel is optionally set depending upon a level of the picture quality. Therefore, it is possible to optionally select a tape storage space in response to the level of the picture quality.

Abstract: 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.
