Abstract

Movies and like video programs are distributed electronically from a program storage and processing center in encrypted format over a satellite channel upon custom order for private viewing of one paying subscriber or a small group of subscribers. Thus, charges may be shared to lower the processing, transmission and royalty costs involved for custom rental of unscheduled programs available from a large storage library facility. The transactions for ordering, paying and receiving a decryption key are made over a two-way interactive wireless satellite network in communication with a nationwide network of subscribers and the video program storage and distribution center. Software controlled subscriber stations permit the monitoring and control of the private viewing conditions to meet various copyright and recording criteria. The transmission is preferably in digital format, and thus may be easily stored in encrypted format for a single private viewing session at a time chosen by the subscriber. The interactive network provides optimal communication of catalog choices, pricing, delivery conditions, automated storage, viewing schedules, payment, confirmation of orders, and conformation to change in business procedures or delivery conditions. Thus, special purpose single-shot local control software may be downloaded from an interactive network processing center to the ordering subscriber station for implementing an order for a private viewing session of a desired movie or other video program.

Claims

1. An interactive wireless video data exchange network, comprising in combination

a plurality of separated subscriber stations located in different geographic areas having facilities for viewing video programs,

a video program storage and processing center for providing selected unscheduled video programs to individual ones of the subscriber stations for viewing,

distribution means for transmitting said video programs over a satellite network between said program center and said subscriber stations in a format for storage at a requesting subscriber station,

an interactive network processing center for interactively communicating with the subscriber stations and the program center, and

interactive communication facilities at the subscriber stations comprising a television viewer including means for interactively processing and implementing wireless transactions with the program center and storing selected video programs for private viewing.

2. The interactive network of claim 1 further comprising:

a set of geographically separated video processing cells, each for communicating interactively with a local subset of said subscriber stations and said interactive processing center, and

communication means at the video cells for processing communications between individual ones of the subscriber stations in its local subset and the interactive network processing center.

3. The interactive network of claim 1 further comprising,

order processing means at the subscriber station for custom ordering of and payment for a selected program stored at the program processing center for private transmission.

4. The interactive network of claim 3 further comprising, facilities for accumulating from different participating subscriber stations a predetermined number of custom orders for a particular stored program at a cost payment shared by the participating subscriber stations and for private transmission of said particular stored program to authorized participating stations at a predetermined time.

5. The interactive network of claim 1 further comprising,

separate wireless satellite communication channels for interactively communicating and distribution of said video programs, and encryption means for encrypting each private viewing of a video program with a unique encryption key.

6. The interactive network of claim 1 wherein said distribution means further comprises means for transmitting said video program in digital format for local storage by the subscriber.

7. The interactive network of claim 1 wherein said interactive communication facilities at the subscriber stations further comprise subscriber station interactive control means including a software controlled data processor, an interactivity control system operated by said software controlled data processor, and means for changing software programs for implementing a diverse range of interactive functions.

8. The interactive network of claim 7 wherein said interactive network processing center further comprises means for downloading software programs to individual subscriber stations.

9. The interactive network of claim 8 further comprising,

software downloaded from said network processing center to a requesting one of said subscriber stations providing for limited private viewing conditions at the subscriber station of a custom ordered program distributed over the satellite network from said program center.

10. The interactive network of claim 9 further comprising at said subscriber stations, software controlled facilities for recording a video program for private viewing distributed by said program center for a single video reproduction at an authorized subscriber viewing station.

11. The interactive network of claim 7, wherein said subscriber stations further comprise software controlled facilities for implementing and paying for a private viewing of a video program for distribution over said satellite network from said program processing center.

12. The interactive network of claim 11 further comprising,

encryption means at said program processing center for uniquely encrypting different individual video programs designated for private viewing with a randomly generated encryption key, and

processing means at said interactive network processing center for controlling a transaction and delivering a decryption key obtained from the program processing center to an authorized subscriber station for receipt of the encrypted video program.

13. The method of releasing video programs from a video storage and distribution center for private viewing of a subscriber, comprising the steps of:

transmitting for private viewing from said distribution center over a satellite broadcast channel encrypted video programs having unique encryption keys for each private viewing, and

transmitting from the distribution center over a wireless two way interactive network channel coupled with an authorized subscriber station the unique key for decrypting the broadcast video program together with order confirmation data.

14. The method of claim 13 further comprising the step of

processing over the interactive network channel catalog menu data for subscriber selection of video programs available for private viewing.

15. The method of claim 13 further comprising the steps of

accepting orders for a shared cost private viewing of a video program from a set of subscribers over said interactive network channel by said distribution center, and

transmitting to each of the subscribers in said set over said interactive network channel the unique key for decrypting the shared cost private viewing video program.
