Abstract:
An interactive information distribution system for providing secure distribution of video-on-demand content. The interactive information distribution system includes at least one programming source for storing at least one partially encrypted video program, and a distribution center including a remote server. The remote server stores the at least one partially encrypted video program received from the at least one programming source. The remote server also processes the partially encrypted video program corresponding to a subscriber requested video program to produce a fully encrypted video program. A subscriber-side distribution network, coupled to the distribution center, causes transmission of the fully encrypted video program to the requesting subscriber.
