. The video programs, such as movies, are typically stored in one of various formats at a central server 10. Subscribers 12 submits requests to the server 10 for particular programs over a communications network 14. The communications network 14 may use any transmission medium, e.g. commercial telephone, cable and satellite networks. Upon receiving a request, server 10 retrieves the video program from mass storage and delivers a data stream, corresponding to the frames of the movie, to the requesting subscriber via distribution network 14. The data stream is directed to a receiver possessed by the subscriber which converts the data stream into signals necessary for playback and viewing of the movie.
As the number of providers for each of the aforementioned services increases, the bandwidth of the channels available for distributing information decreases. To that end, the prior art is replete with systems and methods of maximizing the revenue generated by a given bandwidth of transmission channels. For example, U.S. Pat.

Customer profiles are developed for the recipient describing how important certain characteristics of the broadcast video program, movie or other data are to each customer. From these profiles, an xe2x80x9cagreement matrixxe2x80x9d is calculated by comparing the recipient""s profiles to the actual profiles of the characteristics of the available video programs, movies or other data.
U.S. Pat. No. 5,594,491 to Hodge et al., assigned to the assignee of the present invention, discloses a system and method for distributing video over ADSL telephone lines. To maximize usage of the bandwidth provided by a system storing the information to be distributed, Hodge et al. advocate implementing a Near-Video-On Demand (NVOD) protocol. The NVOD protocol maps a video program onto disk-drive in an interleaved fashion so that the video program is divided into data packets having a plurality of frames with each pair of adjacent frames corresponding to a pair of frames in a viewing sequence displaced from one another by a predetermined number of frames. Mapping the video frames in this manner renders the system compatible with existing video distribution systems, while maximizing the number of users that may access any given program.
