Abstract
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.
Claims19
A video reproduction device for reproducing video data from a video storing medium, the dvice comprising:
- data temporary storing means for receiving video data supplied from a video data storing medium and for temporarily storing the video data;
- data reproducing means for retrieving the video data from the data temporary storing means and for reproducing images;
- reproduction speed determining means for determining a reproduction speed, at which the data reproducing means retrieves the video data from the data temporary storing means and reproduces the corresponding moving picture, to have a value selected from one of a first predetermined value and a second predetermined value lower than the first predetermined value, dependently on an amount of the video data being stored in the temporary storing means;
- and
- reproduction control means for controlling the reproducing means to retrieve the video data from the data temporary storing means at the determined reproduction speed and to reproduce the moving pictures with the determined reproduction speed, the data reproduction means controlled to retrieve the video data at the first predetermined speed reproducing a normal moving picture with the first reproduction speed, the data reproducing means controlled to retrieve the video data at the second predetermined reproduction speed reproducing a still picture with the second reproduction speed, thereby allowing the data reproducing means to continuously reproduce images regardless of whether the supply of the video data from the data storing medium is stopped.
A video reproduction device for retrieving video data from a video data storing medium and for reproducing a moving picture represented by the video data, the device comprising:
- data temporary storing the means for temporarily storing video data, representative of the moving picture, retrieved from the video data storing medium;
- data reproducing means for retrieving the video data from the data temporary storing means and for reproducing the corresponding moving picture;
- reproduction speed determining means for determining a reproduction speed, at which the data reproducing means retrieves the video data from the data temporary storing means and reproduces the corresponding moving picture, to have a value selected from one of a first predetermined value and at least one second predetermined value lower than the first predetermined value, dependently on an amount of the video data being stored in the temporary storing means;
- and
- reproduction control means for controlling the data reproducing means to retrieve the video data from the data temporary storing means at the determined reproduction speed and to reproduce the moving pictures with the determined reproduction speed, the data reproduction means controlled to retrieve the video data at the first predetermined speed reproducing a normal moving picture with the first reproduction speed, the data reproducing means controlled to retrieve the video data at each of the at least one second predetermined reproduction speed reproducing a slow motion picture with the corresponding second reproduction speed.
