Abstract :
Providing efficient support for interactive operations such as fast-forward and fast-backward is essential in video-on-demand and other multimedia server systems. The authors present two basic approaches for scheduling interactive operations, the prefetching approach and the grouping approach. Scheduling algorithms are presented for both fine-grain and coarse-grain data blocks. These algorithms can precisely schedule video streams for both normal playout and interactive operations
