Video data retrieval method for use in video server environments that use striped disks

U.S. Patent Number: 5724543

Abstract: A method for retrieving video data from a video server, the video data having been stored on a plurality of disks based on a disk striping technique. In accordance with one illustrative embodiment, the method comprises the steps of retrieving a predetermined number of bits from the plurality of disks in the video server, and storing that predetermined number of bits in a buffer memory, wherein the number of bits retrieved and stored is based on the number of disks and on the capacity of the buffer memory. These steps, which together may illustratively constitute one round of the video retrieval process, may be repeated until the entire video has been retrieved and, for example, transmitted to the intended recipient(s) at a required transmission rate.
