On the Disk Layout for Periodical Video Broadcast Services

In this paper, we base on region-based disk layout and propose a data placement technique and its associated disk scheduling policy for providing periodical video broadcast services. We present a quantitative study and design algorithms, while still maintain the quality of service, for (1) placing video data on disk, and (2) simultaneously serving of maximum number of broadcast channels with minimal data buffer. By an example evaluation, we demonstrate the advantage of our design.
