    Abstract: A video processing system in which data obtained from sampling an input video format signal according to a first timing signal is written into a first memory according to the first timing signal. Data is read-out of the first memory according to a second timing signal having a frequency equal to N times that of a horizontal synchronizing frequency of the input signal, thereby obtaining data with no time-base fluctuation. M-samples of data from the first memory is then written into a second memory, and data from the second memory is read-out such that the read-out signal from the second memory has a different phase than that of the input video format signal. The system is operable for simultaneously stopping data being read-out of the first memory and data being written into the second memory for a period of time equal to R+kM samples of the input video format signal, wherein R is an integer remainder of N/M, and k is either a positive integer or zero.

Hold circuitry, responsive to a hold instruction signal, is provided to hold the phase relationship of the output signal held just prior to the hold instruction signal for the duration of the hold instruction signal. The hold instruction signal is produced in response to a predetermined condition of the input data signal.

    Abstract: A video information playback system for playing the so called CLV disks which uses a digital video memory for enabling special playback mode operations such as the SLOW mode, the STILL mode, and the FAST mode. In order to simplify the construction of the system, a frequency of write and read clock signals used in the digital video memory is selected n times the horizontal synchronizing signal frequency. A time base servo control part of the system is controlled using a phase difference signal between a playback synchronizing signal and a reference signal whose frequency is 1/n time the frequency of the write and read clock signals. During a track jump operation for a special playback mode operation, a supply of the write clock signal and/or the read clock signal to the reference signal generator is stopped so that the phase difference is maintained constant before and after the track jump operation.

    Abstract: A synchronous control device according to the present invention completes an origin matching between a master section and a slave section without causing a phase difference even when a deceleration device is employed in the master section or in the slave section so as to perform an accurate synchronous control. The synchronous control device constantly detects the phase of a shaft of a master electric motor by a phase detector of the master electric motor according to the outputs of a master rotary encoder, and the phase of a shaft of the master machine by a phase detector of the shaft of the master machine according to the outputs of a master rotary encoder and an origin detector of the shaft of the master machine. In the same manner, the phase of a shaft of a slave electric motor is constantly detected by a phase detector of the slave electric motor according to the outputs of a slave rotary encoder, and the phase of a shaft of a slave machine is constantly detected by a phase detector of the shaft of the slave machine according to the outputs of a slave rotary encoder and an origin detector of the shaft of the slave machine. Then a first phase deviation between the shaft of the master machine and shaft of the slave machine by a first phase deviation detector, and a second phase deviation between the master electric motor and the slave electric motor by a second phase deviation detector for the electric motors are calculated. After an origin between the shaft of the master machine and the shaft of the slave machine is matched based on the first phase deviation, continuously an origin between the master electric motor and the slave electric motor is matched based on the second phase deviation so as to perform the synchronous control.

    Abstract: A scanning method for high-speed reproduction of video data from a recording disk, whereby scanning is executed as a sequence of track jump operations, in which the data detection point of the pickup is caused to jump across tracks of the disk, alternating with intervals of play operation in which data are read from the disk. During each interval of play operation, data obtained from the disk are written into a memory, and thereafter are repetitively read out from the memory to produce an output video signal, until being updated during the next play interval. A display image that is free from noise and disorder is thereby obtained during scanning operation.
