摘要： A video signal input-output circuit and a recording-reproduction apparatus in which a digitally compressed video signal input in packet form can be recorded and reproduced efficiently and in stable fashion. In this apparatus, a clock reference is detected from a packet signal containing the clock reference and a digitally compressed video signal, a time stamp for a packet is generated using a clock signal in phase with the clock reference and added to the particular packet, and the packet signals with the time stamp added thereto are recorded closely to each other in a data storage element such as a magnetic recording medium. At playback, the packet interval is output by being restored to the original length on the basis of the time stamp added to the packet in store.

摘要： For intermittent slow activation, jitter is caused for reproduced image due to increase in the relative speed of a magnetic tape and a magnetic head. To solve this problem, a rotating speed of a drum motor 11 must also be increased. Then, a microcomputer 19 generates a control output PWM using as PWM data a value obtained by adding a prescribed value to a command value of a normal rotating speed, so as to perform correction control for activation. Thereby, correction to constant speed can always be achieved even when there is a difference between operating points of drum motor 11 due to the change in PWM data at the normal speed. Further, since jitter is caused for reproduced image due to the change in the relative speed of the magnetic tape and the magnetic head in braking a capstan motor 10, jitter is corrected by subtracting a prescribed value from the drum control PWM data at the normal rotating speed.
摘要翻译：对于间歇慢激活，由于磁带和磁头的相对速度的增加，对再现图像造成抖动。为了解决这个问题，滚筒电动机11的旋转速度也必须增加。然后，微型计算机19使用作为PWM数据的控制输出PWM，生成通过将规定值加到正常转速的指令值而获得的值，以进行激活的校正控制。因此，即使由于正常速度下的PWM数据的变化，当鼓电动机11的工作点之间存在差异时，也可以始终实现恒定速度的校正。此外，由于在主导电动机10制动时由于磁带和磁头的相对速度的变化引起的再现图像的抖动，所以通过从正常旋转的滚筒控制PWM数据减去规定值来校正抖动速度。

摘要： A reproducing device for reproducing information from a tape-shaped recording medium, such as a magnetic tape, in which address information and data are recorded on the recording medium on a plurality of inclined tracks. The address information is composed of a track address and a block address. The reproducing device, which reads and reproduces data from the tape-shaped recording medium includes a reproducing unit, an address extracting unit, a memory, a driving unit and a controller. The reproducing unit reads out data from the tape-shaped reproducing medium for data reproduction. The reproducing unit has a rotary head configured for scanning a plurality of tracks of the tape-shaped recording medium for reading out data from the recording medium. The address extracting unit extracts the address information from data read out by the reproducing unit from one scan of the tape-shaped recording medium by the rotary head. The memory stores data read out from the reproducing unit. The data read out from the reproducing unit is written in the memory based upon the address information extracted by the address extraction unit. The driving unit runs the tape-shaped recording medium. The controller generates read-out addresses for reading out the data stored in the memory. The controller controls the driving unit based upon the address information which is extracted by the address extraction unit and which is associated with pre-set locations on the track of the tape-shaped recording medium.
