PCT No. PCT / US95 / 15429 Sec. 371 Date Dec. 24, 1997 Sec. 102(e) Date Dec. 24, 1997 PCT Filed Nov. 29, 1995 PCT Pub. No. WO96 / 17467 PCT Pub. Date Jun. 6, 1996A system and method for scheduling the receipt of desired movies and other forms of data from a network, which simultaneously distributes many sources of such data to many customers, as in a cable television system. 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 "agreement matrix" is calculated by comparing the recipient's profiles to the actual profiles of the characteristics of the available video programs, movies, or other data. The agreement matrix thus characterizes the attractiveness of each video program, movie, or other data to each prospective customer. "Virtual" channels are generated from the agreement matrix to produce a series of video or data programming which will provide the greatest satisfaction to each customer. Feedback paths are also provided so that the customer's profiles and / or the profiles of the video programs or other data may be modified to reflect actual usage, and so that the data downloaded to the customer's set top terminal may be minimized. Kiosks are also developed which assist customers in the selection of videos, music, books, and the like in accordance with the customer's objective profiles.

An interactive television system that renders on-demand interactive multimedia services for a community of users. The interactive multimedia is delivered to each user on a TV or on a LAN-node (Local-Area-Network) computer through an "interactive TV channel" created and controlled by a Channel-processor, which can be implemented as either a PC or a high-end workstation. The system employs a direct-access on-demand workgroup server. It is equipped with the primary on-demand multimedia data base stored on a hard disk subsystem that is connected directly to the Channel-processors through an internal workgroup link. Using a no-overhead server technology, the connected workgrouped Channel-processors can all concurrently retrieve and process the data directly from the hard disk subsystem without resorting to a stand-alone server system for data retrieving and downloading. The system also employs peer-to-peer workgroup connectivity, so that all of the workgrouped Channel-processors that are connected to the workgroup server through the internal workgroup link, can communicate with one another.
