The case for aggressivepartial preloadingin broadcasting protocols for video-on-demand

Broadcasting protocols for video-on-demand usually consume over fifty percent of their bandwidth to distribute the first ten to fifteen minutes of the videos they distribute. Since all these protocols require the user set-top box to include a disk drive, we propose to use this drive to store the first five to twenty minutes of the ten to twenty most popular videos. This will provide low-cost instant access to these videos.
