Abstract

An interactive multimedia system with distributed processing and storage of video picture information and associated data and sound in nodes disposed throughout a cable television distribution system. The nodes are coupled to the feeder cable of the cable distribution system. Each node in the system receives a substantially identical copy of the interactive video picture information and related data from a regional processing center. The nodes can receive the Video picture information through the cable television distribution system or externally of the cable system. The users at home televisions associated with a particular node interact directly with the video picture information in that node, rather than with the information stored in the regional processing center or some other remote location, which enables the system to quickly display photographic quality images and complex graphics, as well as sound, at the users'"'"' televisions in response to commands received by the users. The nodes can also be used for decompressing compressed television programming and distributing the decompressed programming to home televisions connected to the system.

Claims

1. A system for transmitting video picture information to home televisions over a fiber optic telephone system, comprising:

means for distributing said video picture information over said fiber optic telephone system; and

a plurality of nodes, each associated with a plurality of subscribers viewing said home televisions, each of said nodes being coupled to said fiber optic telephone system for capturing and storing said video picture information transmitted over said fiber optic telephone system and for distributing said video picture information, upon demand, to said subscribers associated therewith, wherein said subscribers viewing said home televisions can display and interact with said video picture information stored in said associated node by communicating to said associated node, said associated node containing a substantially complete copy of said video picture information which said subscribers can display and interact with, such that said subscribers interact directly with said video picture information stored in said associated node, said video picture information including full-motion video information.

2. A system as recited in claim 1, wherein said associated node is disposed in a remote terminal of said fiber optic telephone system.

3. A system as recited in claim 1, wherein said associated node distributes said video picture information over fiber optic cable to curb pedestals associated with said subscribers.

4. A system as recited in claim 3, wherein said curb pedestals each include an optical network interface and are coupled by coaxial cable to the home televisions associated therewith, said video picture information being transmitted from said associated node to said subscribers over said coaxial cable.

5. A system as recited in claim 2, wherein said means for distributing said video picture information over said fiber optic telephone system comprises a store and forward computer located in a central office of said fiber optic telephone system, said central office being coupled to said remote terminal by fiber optic cable, said store and forward computer distributing said video picture information to said associated node in said remote terminal over said fiber optic cable.

6. A system as recited in claim 1, wherein said video picture information is transmitted to said subscribers by said associated node over a time domain multiplex (TDM) channel.

7. A system as recited in claim 1, wherein each of said subscribers viewing said home televisions can communicate, to said associated node, a request for selected video picture information from said associated node, said associated node including:

(i) means for dynamically assigning one of a plurality of channels to the subscriber requesting the selected video picture information; and

(ii) means for transmitting said selected video picture information to the home television of the requesting subscriber over the assigned channel.

8. A system as recited in claim 7, wherein each of said home televisions includes an associated home interface controller with means for receiving said selected video picture information transmitted by said associated node over said assigned channel.
