ABSTRACT:
A method for reducing the disk bandwidth capacity required by a multimedia server by selectively retaining blocks that have already been read in by one stream for re-use by another. Due to stream-dependent block buffering, the storage requirement is less than that for whole-movie buffering and because the policy is dynamic, it also adapts rapidly to changing access patterns.
