Inventor(s)Hoarty; W. Leo (Santa Clara, CA); Soske; Joshua W. (Sunnyvale, CA); Lauder; Gary M. (New York, NY); Snell; Stephen C. (Aptos, CA); Fisher; Delmer D. (Milpitas, CA); North; John (Mountain View, CA)
AbstractAn interactive home information system having a node in television communication and data communication with a group of home interface controllers. At each home interface controller, there is a signal input for receiving television signals from the node over a cable television distribution network and a data transceiver for conducting data communications with the node. The node determines whether a home interface controller is requesting interactive service. For each interface controller requesting interactive service, the node assigns a television information signal to the requesting home interface controller. Thus, signal assignment is accomplished on a demand basis for those interface controllers determined to be placed in an interactive mode. Signal assignment may involve selection of a given carrier frequency. Alternatively, signal assignment may involve selection of a time slice.
