摘要： PURPOSE:To execute a video reproducing system having a multiple function at low costs by using a picture memory used for synchronizm converting processing at the time of special reproduction for the other video signal processing at the time of normal reproduction. CONSTITUTION:When the special reproduction such as still picture reproduction and double speed reproduction, switching circuits 11, 12 and 13 are switched on a fixed terminal (a) side, and the synchronization converting processing is used with the use of a picture memory 9. Thus, a video signal, whose synchronizing signal is discontinuous due to a track jump operation, can be converted into that whose synchronizing signal is continuous. When the normal reproduction is executed, the switching circuits 11, 12 and 13 are switched on a fixed terminal (b) side, the picture memory 9 is connected to a noise decreasing circuit 14, and used for the delay memory of a circular type noise decreasing circuit. Consequently, without using the special memory, the video reproducing system having the multiple function can be formed at the low costs.

摘要： PURPOSE:To reproduce a picture with smooth movement even when movement of picture exists without deterioration in the vertical resolution in case of less movement of picture by selecting two fields constituting one frame in a multiplex video signal through the combination of two fields parted by a prescribed field number in each channel. CONSTITUTION:A video signal of each channel is retarded by a period corresponding to two frames by a 2-frame delay circuit 11 and becomes an (a) input of a changeover switch 12. The changeover switch 12 selects the odd number field in two-preceding frame being an (a) input in case of an odd number field based on the discrimination output of a field discrimination circuit 13 and selects the existing field in case of an even number field. Thus, the two fields constituting one frame is the combination of the even field of the existing frame and the odd number field in two preceding frames. As a result, since the missing period of the signal is interpolated by the one field signal fetched in 2-frame period, a smooth reproduction picture not causing vibratory movement is obtained.

摘要： PURPOSE:To execute a stable jumping operation and an exact tracking by holding an error signal just preceding to the opening of a switching means and impressing it to a driving means. CONSTITUTION:A low frequency area equalizer 9, which is a signal holding means, is provided in the rear step of a switching circuit 8 to execute the opening/closing of a servo loop. At a time point to open the servo loop, the error signal just preceding to the opening of the servo loop is supplied from the signal holding means 9 to a pickup driving means together with an accelerating signal. Then the pickup means is accelerated and the signal holding means 9 is operated even as a circuit for characteristic compensation of a phase compensating circuit, etc., in the servo loop. Thus, the track jumping operation of the pickup means can be stably and securely executed with the simple constitution and the converging of the information reading point of the pickup means can be speedily executed to the track after the jumping.

摘要： PURPOSE:To stably perform specific reproduction, by shifting the information detecting point of a pickup to a front plane from a designated position in a reading direction, by a jump operation. CONSTITUTION:Since the next jump operation is not started up until a video signal of one field after the jump operation is started, and one rotational pulse is outputted for two times, and also, the video signal of one field obtained after the outputs of the rotational pulse for two times, is written, it is resulted that the video signal of one field having no time base error, can be obtained, and also, the video signal of one field having no time base error is written on a memory, and a satisfactory reproducing picture can be obtained even in the reproduction at K-fold speed. At this time, since the jump operation is started up at every two rotation of a disk, the cycle of the jump operation is prolonged, but, so that the shift distance of the information detecting point of the pickup 3 by one time of jump operation is doubled, the number of track jump per one rotation of the disk satisfy the condition of the reproduction at K-fold speed.

摘要： PURPOSE:To execute stably and in a short time pull-in of a tracking servo by varying a loop gain in accordance with a period in which a distance between a track and a recording information detecting point is increased, and other period. CONSTITUTION:A detecting signal of a recording information detecting point 2 by a photodetector 11 is compared with a reference value by a comparator 14, a comparing signal is applied to a time constant circuit 15, and a signal E by which a period in which a distance between the detecting point 2 and a track 1 is increased is decreased, and other period is increased in generated. In this state, when the photodetector 11 photodetects a signal from the track 1, the gain of a voltage control amplifier 10 for amplifying a track error signal C formed by photodetectors 5, 6 for photodetecting a signal from both sides of the track 1 is set to a prescribed value in a period in which a distance between the detecting point and the track is increased, and damping is executed. Other period is set to ''0'', and a tracking actuator is operated in a state that a relative moving speed in the orthogonal direction of the track 1 of the detecting point 2 is always low. As a result, pull-in of a tracking servo-system is executed stably and in a short time.

摘要： PURPOSE:To prevent color irregularity and color blurring by preventing abrupt variation in the phase difference between the color burst signal in a video signal read by bringing a signal delay time under open-loop control and a reference chrominance subcarrier. CONSTITUTION:A time-axis error signal including an extremely-high-frequency component which can not be prevented by a tangential mirror 11 is supplied to the control input terminal of a variable delay line 13 which delays the output of a demodulator 2 through a capacitor C. Therefore, the signal delay time of the variable delay line 13 varies under the open-loop control so that variation in time-axis error which has an extremely small amplitude which can not be removed by the tangential mirror 11, but has an extremely high frequency is canceled. Therefore, the variation in the time-axis error of the video signal outputted from the variable delay line 13 is prevented to reduce the steady deviation between the phase of the color burst and that of the reference chrominance subcarrier sufficiently.
