Abstract

A multimedia data is a data mixed of formatted data like a text and unformatted data like an audio and video. Multimedia data has characteristics that it need large amount of storage, wide network bandwidth and real time responsibility. Because of these characteristics, the VOD server and continuous media storage server have a disk stripe structure or disk array structure(RAID). In the parallel disk access system, high-speed playback of continuous media using segment interleaving may not ensure QoS of other clients because of the concentrated load within some disks. The load concentration of disks is related to both the number of disks in the system and playback rate continuous media. In this paper, we describe that high-speed playback scheme, which is independent of the number of disks and playback rate can be achieved by technique of changing the interval of access to segment location We show the experimental result of this technique in this paper.
