    Abstract: IT IS AN OBJECT OF THE PRESENT INVENTION TO PROVIDE A VARIABLE-SPEED PLAYBACK APPARATUS FOR DIGITAL VIDEO SIGNALS WHEREIN THE TAPE TRAVELING SPEED CAN BE CONTROLLED WITH A HIGH DEGREE OF ACCURACY. A TRACE PHASE PROCESSING UNIT (33) EMPLOYED IN A MICROCOMPUTER (25) COMPUTES THE TRACE PHASE OF A MAGNETIC HEAD FROM REPRODUCED TRACK AND SYNCHRONIZATION BLOCK NUMBERS. THIS TRACE PHASE IS COMPARED TO REFERENCE TRACE PHASE REF OUTPUT BY A CYCLIC COUNTER (29) TO PRODUCE A PHASE WHICH IS SUPPLIED TO A SPEED CONTROL UNIT (26).FIG. 1

    Abstract: In a variable-speed playback apparatus for digital video signals wherein the tape traveling speed can be controlled with a high degree of accuracy, a trace phase processing unit (33) employed in a microcomputer (25) computes the track and synchronization block numbers. This trace phase is compared to a reference trace phase (Ref) output by a cyclic counter (29) to produce a phase error which is supplied to a speed control unit (26).

    Abstract: PROBLEM TO BE SOLVED: To perform search reproduction at a prescribed double speed and at two times as fast as the prescribed double speed. SOLUTION: A track for search is allocated to image data for search by depending on which area data the image data for search belongs to between a central part area C (areas C0 to C8) on an image for search and peripheral parts P (areas P0 to P8), further which area data the image data for search belongs to among the nine areas C0 to C8 of the area C or which area data the image data for search belongs to among the nine areas P0 to P8 of the areas P. As a result, the entire image for search is displayed in search reproduction at the prescribed double speed, and the image of the area C or the image of the areas P is alternately reproduced in search reproduction at the two times as fast as the double speed.

    Abstract: PROBLEM TO BE SOLVED: To realize a phase lock of ±24 double speed highly accurately without using sub-code data in a recording and reproducing apparatus performing recording and reproducing of digital data through a tilt track of a magnetic tape by a rotary head. SOLUTION: When such control is performed by a capstan servo arithmetic part 71 of a reproduction system 20 that phase lock is performed with ±24 double speed and the search data is traced and reproduced, if search data cannot be obtained from a detection result of the search data locking to a tilt track of the prescribed track number, speed is kept in the fixed direction and locked by the next error correction block, at a position being the remotest from a target position, the above operation is repeated twice, after search data can be obtained, control of locking is performed.

    Abstract: PROBLEM TO BE SOLVED: To provide an image reproducing device that can stabilize image reproduction at variable speed reproduction and reduce the processing time required for reaching a stable state. SOLUTION: The reproducing method of this invention includes a step S2 of transmitting a SYNC/ID detection request data to a SYNC/ID detection section from a latch data generating section when a step S1 discriminates that variable speed reproduction is commanded; a step S3 of generating the SYNC/ID detection data corresponding to the SYNC/ID detection request data by the SYNC/ID detection section, a step S4 of receiving the SYNC/ID detection data by the latch data generating section; a step S5 of generating latch data, a step S6 of discriminating whether or not an object SB (Synchronized Block) is detected in a target Trp (Track pair); steps S7, S9 of discriminating a connection state of a switch depending on the result of discrimination; and a step S8 of switching the switch depending on the connection state.
