摘要： An interactive television system, for providing interactive television service. The interactive television system has an information source available at a remote location for supplying a plurality of information services and an information network in communication with the remote location for delivering the information services to subscriber televisions. The interactive television system includes a plurality of home interface controllers. One of the home interface controllers is associated with a subscriber television. The home interface controller includes a data transceiver that is in communication with the remote location, and a selection input for receiving signals from a subscriber selection device. The home interface controller also has an interactive mode. The interactive television system also includes a node that is disposed at the remote location and provides information signals for transmission via the information network, so that when a given one of the home interface controllers is in the interactive mode signals at the selection input of the given home interface controller resulting from subscriber input via a subscriber selection device generate control data. The node receives the control data over the information network from the data transceiver of the given home interface controller. The node transmits a selected information signal that is capable of full motion video on a television information signal on the information network to the subscriber television with which the given controller is associated so that the given information signal is made available to the subscriber television. The content of the information signal is modified in response to control data resulting from subscriber input via the subscriber selection device.
