Abstract
The present invention relates to a method of processing video data comprising the transferral of the video data to a first memory buffer and the manipulation of video data. The manipulated video data is then transferred to a second memory buffer before being written to a plurality of discs.
Claims24
A method of processing video data comprising the sequential steps of;
- (a) transferring the video data to a first memory buffer and manipulating said video data;
- (c) transferring said manipulated video data to a second memory buffer;
- and
- (d) writing said manipulated video data to a plurality of discs.
A method of processing video data comprising the sequential steps of:
- (a) transferring the video data to a first memory buffer and manipulating said video data comprising dividing said video data into a plurality of blocks;
- (b) and transferring said plurality of blocks to a plurality of disc stripe buffers in a second memory buffer such that consecutive blocks are not grouped in the same disc stripe buffer;
- and
- (c) writing said manipulated video data in said plurality of disc stripe buffers to a plurality of discs.
A method of extracting video data from a plurality of discs comprising the sequential steps of:
- (a) accessing manipulated video data on said plurality of discs;
- (b) transferring said manipulated video data to a second memory buffer;
- (c) converting said manipulated video data into video data and transferring the video data to a first memory buffer.
A method of processing video data comprising the steps of dividing a video image into a series of stripes which are each transferred to a separate first memory buffer which is connected to a plurality of disc drives.
