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 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. The nodes can also be used to distribute customized commercials to television viewers.
A system for distributing customized commercials to television viewers viewing home televisions coupled to a cable television distribution system, comprising: a node coupled to said cable television distribution system and being associated with a portion of said home televisions coupled to said cabl
A system for distributing customized commercials to television viewers viewing home televisions coupled to a cable television distribution system, comprising: a node coupled to said cable television distribution system and being associated with a portion of said home televisions coupled to said cable television distribution system, said node distributing video picture information, upon demand, to said television viewers viewing said home televisions associated with said node, said video picture information including full-motion video information; wherein a television viewer viewing one of said home televisions can communicate, to the node associated therewith, a request for selected video picture information from the associated node, the associated node including: (i) means for dynamically assigning one of a plurality of channels to the television viewer requesting the selected video picture information; and (ii) means for transmitting the selected video picture information to said one home television of the requesting television viewer over the assigned channel; wherein the associated node further comprises means for automatically switching a television channel received by the television viewer to a secondary channel containing a particular commercial interval, said particular customized commercial being transmitted to the television viewer from the associated node.
