Abstract
A method and system for providing programming on demand service to television subscribers. In a preferred embodiment, each group of viewers that requests a given program is coupled to a separate video 'feed' of the program. Each individual feed shows the program at a different rate. In this manner a second group of viewers who begin viewing a program after a first group of viewers may 'catch up' to the first group. Whenever such an 'intersection' occurs, the groups are merged and view the remainder of the movie on a single feed. In this manner the total number of feeds to required to provide video on demand service to a large number of viewers is reduced.
