When the data supply rate from the data storing unit 11 drops and the amount of data remaining in the buffer memory 21 decreases, the calculation circuit 25 determines a data reproduction speed at which reproduction should be performed, dependently on the amount of data in the buffer memory 21. Accordingly, the video reading circuit 23 is controlled to retrieve video data from the buffer memory 21 at a reduced reproduction speed. The monitor 13 reproduces a slow motion pictures, which leads to an enhancement of the buffer memory.

Video reproduction device

A data transmission system includes a polling modem and a central control unit that receives a response signal from a terminal. A data transmission central control unit performs polling type transmission to transmit an information data unit to the terminal that has requested the information data unit. The central control unit also performs loop type transmission to cyclically transmit information data units with their loop flags being set to the terminals in succession. The control portion in the terminals selects the transmission that requires the shortest waiting time.

Data transmission system for transmitting information from a central

A microcomputer selects one of a plurality of drive units, and controls the selected drive unit to reproduce image data from a video disk located thereon. When a reproduction error occurs in the thus reproducing drive unit, the microcomputer selects another drive unit, and controls the drive unit to reproduce images. Accordingly, it is possible to always provide accurate images.
