Abstract

A system and method to efficiently deliver multimedia interactive and linear programming on a large-scale network is disclosed. The system is designed to be hierarchical in nature in order to avoid the huge processing and storage requirements of a system utilizing centralized storage and system control. The stored program material is segmented into portions and each program segment is transmitted to the receiving system component in less than real-time on an as-needed basis. Methods for efficiently using system resources such as bandwidth, storage and processing time to maintain an optimally-performing system that results in minimal latency for the end-user'"'"'s interaction with the system are disclosed.

Claims

1. A system for distribution of interactive multimedia and linear programs comprising:

at least one bunker, operatively connected to at least one data studio, for receiving and storing preprocessed multimedia program webs from said data studio, said data studio being operative for said design and/or production of said program webs which include control scripts to define presentation to the user and interaction with the user and processing engines to process content-dependent data as well as the multimedia data itself; and

at least one hub connected to a communication network and connected to said bunker for selectively retrieving and storing said programs from said bunker and based on program web content proactively predicting needed data for distribution of said selected program webs using said communication network; and

at least one client transceiver connected to said communications network for receiving, storing and selectively enabling a user to utilize said program webs;

whereby multimedia program webs which include said presentation and interaction definitions, processing engines and multimedia data are prepared at said data studio, stored as online-ready files and segments in said bunker and said program webs are selectively accessbile for online distribution from the hub to the client transceiver via said communications network.

2. A system as in claim 1 whereby said Client transceiver is also operative for transmitting information representative of a request for one of said programs or program segments to said hub.

3. A system as in claim 1 whereby one or more additional Hubs are connected between said Hub and said communications network for further selective storing of said programs and segments.

4. A system as in claim 2 whereby said selective retrieving and storing at said Hub is responsive to said program request from said Client transceiver.

5. A system as in claim 4 further comprising Hub data processing means for processing look-ahead algorithms to predict said Client transceiver requests.

6. A system as in claim 5 further comprising Hub data processing means for collecting system usage information for use in said look-ahead algorithms.

7. A system as in claim 1 whereby said program distribution from said Hub to said Client transceiver is operative for transmission of segments of said program whereby said Hub storage is reduced by storing segments of said programs rather than the programs in their entirety.

8. A system as in claim 3 whereby storage of said program segments is distributed through one or more of said Hubs whereby the total inventory of said system is distributed throughout the system by the storage of said program segments at said multiple Hubs.

9. A system as in claim 1 whereby said program distribution from said Hub to said Client transceiver is operative for transmission of segments of said program whereby said Client storage is reduced by receiving segments of said programs rather than the programs in their entirety.

10. A system as in claim 1 further comprising segmentation of said programs into smaller program segments for storage at said Bunker, storage at said Hub and transmission from said Hub to said Client.

11. A system as in claim 10 whereby the transmission of said smaller program segments results in less latency in use of said program segment at said Client by virtue of the lesser transmission time of said program segments.

12. A system as in claim 10 whereby the next sequential program segment is transmitted to said Client prior to said Client'"'"'s need for said program segment whereby program usage at said Client is maintained as a continuos, seamless program by timely reception of said program segments.

13. A system as in claim 10 whereby said program segments are preferentially stored at the system element closest to said Client, namely the closest Hub, followed preferentially by the closest possible Hub and then the Bunker whereby program segments required by the Client are satisfied by the closest possible node on the system.

14. A system as in claim 8 whereby said segmentation is determined by logical and symantical segmentation of said multimedia program webs representing user interaction with and containing said multimedia data.

15. A system as in claim 9 whereby said segmentation is determined by logical and symantical segmentation of said multimedia program webs representing user interaction with and containing said multimedia data.

16. A system as in claim 10 whereby said segmentation is determined by logical and symantical segmentation of said multimedia program webs representing user interaction with and containing said multimedia data.

17. A system as in claim 11 whereby said segmentation is determined by logical and symantical segmentation of said multimedia program webs representing user interaction with and containing said multimedia data.

18. A system as in claim 12 whereby said segmentation is determined by logical and symantical segmentation of said multimedia program webs representing user interaction with and containing said multimedia data.

19. A system as in claim 13 whereby said segmentation is determined by logical and symantical segmentation of said multimedia program webs representing user interaction with and containing said multimedia data.

20. A method for providing selective distribution and control of multimedia and linear programs over a communications network comprising the following steps:

processing the multimedia program comprising one or more of;

compression, editing, and adding metadata, said metadata including information regarding file characteristics, content-dependent information and interactivity-related information; and

transferring said processed multimedia programs to at least one bunker for offline storage; and

selectively transferring said programs to at least one Hub for on-line storage; and

receiving program requests at said Hub from a Client destination via a communications network; and

transmitting said programs to one or more Client destinations via said communications network responsive to said requests; and

receiving said programs for storage and viewing at one or more client destinations via said communications network.

21. A method as in claim 20 wherein said step of selective transferring of programs to said Hub is carried out by transferring segments of said programs.
