Video data reproducing apparatus for reproducing video data and method therefor
First Claim
1. A video data reproducing apparatus for reproducing video data to images, said apparatus comprising:
- first recording means for dividing said video data into at least two first blocks, and for recording the at least two first blocks of said video data at random positions;
second recording means for dividing said video data into at least two second blocks, and for recording the at least two second blocks of said video data;
in serial positions;
file controller means for controlling said video data recorded in said first recording means and divided into the at least two first blocks;
first reading means for reading desired video data from said video data recorded in said first recording means;
second reading means for reading desired video data from said video data recorded in said second recording means, said second reading means;
a buffer memory to read video data of a later block recorded in said second recording means before completion of reproduction of video data of a former block recorded in said second recording means;
decision means for selecting video data of one of said first recording means and said second recording means to be reproduced, wherein if said video data of said first recording means are selected, said video data recorded in said first recording means are read out through said file controller means, and if said video data of said second recording means is selected, said video data recorded in said second recording means are read out from said second recording means to said buffer memory without any intervention of said file controller means; and
reproducing means for reproducing said video data read out by said one of said first recording means and said second recording means.

Abstract
A video data reproducing apparatus and method therefor having a file controller section for controlling video data recorded on a first recording medium at random positions, and further, having a second recording medium for recording the video data in a serial manner. The apparatus includes a decision section for judging whether to select the video data of either the first recording medium or the second recording medium. A first reading section reads out the data of the first recording medium through the file controller section when the first recording medium is selected by the decision section, and a second reading section reads out the video data to a buffer memory from the second recording medium, without any intervention of the file controller section, when the second recording medium is selected by the decision section.

9. A video data reproducing apparatus for reproducing video data to generate a motion picture, said apparatus comprising:
-
first recording means for dividing said video data into a first plurality of blocks recorded at random positions; second recording means for dividing said video data into a second plurality of blocks recorded in serial positions; file controller means for controlling said video data divided into said first plurality of blocks and recorded in said first recording means; first reading means for reading desired first data from said video data recorded in said first recording means; second reading means for reading desired second data from said video data recorded in said second recording means; decision means determining which of said first and second data should be read by said first and second reading means, wherein if said first data should be read out, said first data are read out through said file controller means, and if said second data should be read out, said second data are read out without the use of said file controller means; reproducing means for reproducing and displaying said first and second data read out from said corresponding first and second recording means; and a buffer memory to store said second data read out from said second recording means, and to read out said second data in said second plurality of blocks, wherein a latter block of said stored second data are read out before completion of reproduction and display of a former block by said reproducing means. - View Dependent Claims (10, 11)

13. A method of reproducing video data to generate images, said method comprising:
-
recording said video data on at least one of a first recording medium which stores said video data in first blocks at random positions as first data and a second recording medium which stores said video data in second blocks in serial positions as second data; selecting one of said first data and said second data to be reproduced; reading said selected one of said first and second data from the corresponding first and second recording medium, and if said first data is selected, using a file controller to control the read out of said first data, and if said second data is selected, the file controller is not used to control the read out of said second data; if selected, storing said second data in a buffer and then reading out said second data from the buffer in the second blocks; and reproducing said second data, wherein a later one of the second blocks is read out of the buffer before completion of said reproducing of a former one of the second blocks. - View Dependent Claims (14, 15)
