Abstract

A management system and method for use with on-demand cable programming, wherein a customer telephones a cable supplier and requests that a particular video program be played. The management system uses a plurality of video sources, wherein each of the video sources is capable of playing the requested video program. A telephone switch system and routing table are used to route incoming customer requests directly to the interface in control of the video source serving the region from where the request originated. The volume of requests received from each customer region serviced by the cable supplier is evaluated. If the volume of customer requests surpasses a threshold level, then additional video sources are added to the cable network by the cable supplier. The cable head ends that service the various customer regions are then reassigned among the new number of video sources so that the volume of requests is generally evenly divided among the multiple video sources, concurrently, the routing table is changed to maintain the geographic association between customer regions and each appropriate video source.

Claims

a plurality of video sources capable of playing the requested programming, wherein said plurality of video sources includes a first video source connected to the cable broadcasting network and at least one subsequent video source capable of being selectively connected to said cable broadcasting network;

demand evaluation means for evaluating the requested programming and determining whether the requested programming exceeds a threshold level, wherein said at least one subsequent video source is added to said cable broadcasting network when the requested programming surpasses said threshold level; and

assignment means for assigning each of said cable head ends to one of said video sources connected to said cable broadcasting network, wherein the requested programming for each of said video sources is maintained below said threshold level.

2. The system according to claim 1, further including a response means for receiving and responding to requests from customers serviced by one of said cable head ends and directing one of said video sources to play the requested programming.

3. The system according to claim 2, wherein said requests are telephone requests and said system further including telephone switching means for automatically directing the telephone requests received from customers serviced by one of said cable head ends to the response means that directs one of said video sources assigned to that one of said cable head ends.

4. The system according to claim 1, wherein said demand evaluation means further controls the removal of said at least one subsequent video source from said cable broadcasting network when the requested programming falls below a minimum level.

5. The system according to claim 1, wherein said plurality of video sources is equal in number to said plurality of cable head ends.

6. The system according to claim 2, wherein said assignment means assigns each of said cable head ends to one of said video sources connected to said cable broadcasting network in a manner so that the requests received by the response means for each of said video sources are generally equal.

7. The system according to claim 1, wherein said at least one subsequent video source is configured to include a plurality of subsequent video sources.

8. The system according to claim 7, wherein said demand evaluation means adds one of said subsequent video sources to said cable broadcasting network each time the requested programming for one of said video sources already connected to said cable broadcasting network surpasses said threshold level.

9. The system according to claim 7, wherein said demand evaluation means removes one of said subsequent video sources from said cable broadcasting network each time the requested programming for one of said video sources falls below a minimum level.

10. The system according to claim 2, wherein said requests are on-line requests and said system further includes switching means for automatically directing the on-line requests received from customers serviced by one of said cable head ends to the response means that directs one of said video sources assigned to that one of said cable head ends.

11. The system according to claim 1, wherein said cable broadcasting network includes multiple cable providers, said demand evaluation means and said assignment means being operable in connection with more than one of said cable providers.

12. A video jukebox management system for use by a cable supplier that broadcasts on-request video program services across multiple cable heads, said system comprising:

a plurality of video sources, wherein each of said video sources is capable of playing a requested video program;

control means for selectively assigning each of said cable head ends to one of a number of said video sources, wherein the number of video sources is dependent upon the amount of video program requests received by the cable supplier within a period of time;

a telephone call response means, associated with each one of said video sources, for instructing a video source coupled thereto to play a particular video program in response to a telephone request; and

a telephone call directing means for directing telephone requests from customers serviced by said cable head ends to the telephone call response means associated with said video sources, wherein said telephone directing means is capable of determining an area corresponding to one of said cable head ends from which each telephone request originates and forwards each telephone request to telephone request to telephone call response means that directs one said video sources connected to the one of said cable head ends that services said area.

13. A video jukebox management system for use by a cable supplier that broadcasts on-request video program services across a plurality of cable heads, said system comprising:

a plurality of video programs, wherein each of said video programs is capable of being played through a plurality of video sources;

control means for selectively scheduling the playing of each of said plurality of programs through at least a selected one of said plurality of video sources;

control means for selectively assigning each of said cable head ends to one of a number of said video sources, wherein the number of video sources is dependent upon the amount of video requests received by the cable supplier; and

means for varying said number of said video sources in response to a number of video requests such that each requested video program is viewed by a corresponding requestor within a reasonable time period;

wherein each of said cable head ends serves a predetermined customer region and the cable supplier receives a variable amount of telephone requests from each said predetermined customer region, and wherein said control means for selectively assigning assigns cable head ends to said video sources services an overall customer region that generates a generally equal amount of telephone requests.

14. A video jukebox management system for use by a cable supplier that broadcasts on-request video program services across a plurality of cable heads, said system comprising:

a plurality of video programs, wherein each of said video programs is capable of being played through a plurality of video sources;

control means for selectively scheduling the playing of each of said plurality of programs through at least a selected one of said plurality of video sources;

control means for selectively assigning each of said cable head ends to one of a number of said video sources, wherein the number of video sources is dependent upon the amount of video requests received by the cable supplier; and

means for varying said number of said video sources in response to a number of video requests such that each requested video program is viewed by a corresponding requestor within a reasonable time period;

wherein said control means for selectively assigning adds an additional video source to said cable head ends each time the amount of video requests for one of said video sources already assigned to one of said cable head ends surpasses a threshold value.

15. The system according to claim 14, wherein said control means disconnects a video source from said cable head ends each time the amount of video requests for one of said video sources already assigned to one of said cable head ends falls below a minimum value.
