Abstract
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 Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
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.
Claim 2
Independent Claim
159 words
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.
Claim 3
Dependent Claim
23 words
A system as recited in claim 1, wherein said associated node is disposed in a remote terminal of said fiber optic telephone system.
Claim 4
Dependent Claim
27 words
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.
Claim 5
Dependent Claim
46 words
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.
