Multimedia Resource Scheduling
Multimedia information systems are different from the traditional information systems, where continuous media (audio/video) requests special storage and delivery requirements due to (i) the large transfer rate, (ii) the storage space required, and (iii) the real-time and continuous nature. Due to the special characteristic of continuous media, different types of scheduling are proposed, namely, the disk scheduling and stream scheduling. On one hand, the disk scheduling is to tackle both the large storage space and the corresponding large transfer rate requirements. On the other hand, the stream scheduling is to schedule requests from multiple clients, in order to minimize the delay in satisfying the requests. It attempts to support as many requests as possible, and at the same time, keep the real-time and continuous nature.
Continuous media adds additional requirements to the traditional information systems. In order to satisfy these new requirements,...
