Storage design and retrieval of continuous multimedia using multi-disks

Abstract

In the domain of multimedia applications, continuous display is an important issue. In this paper, we present a practical method to allocate disk storage for multimedia data so that continuous requirement can be met. This technique explores data-transfer parallelism on a multidisk system. Moreover, in order to ensure that continuous retrieval can be achieved in a multiuser environment, we propose the dynamic scheduling mechanism for real-time object retrieval. It can be seen that, a good scheduling can explore higher access concurrency in display of multimedia applications. Several approaches with different trade-off based upon this mechanism are proposed in this paper, which include delay initiation, read-ahead, migration, segmentation and integration.
