ABSTRACT:
An interactive television system employs a telephone connection in a two-way manner to send command signals from a viewer to a central controller to select various presentations and to send the audio portion of such presentations from a central location to individual viewers. When a connection is first established over the telephone lines between a viewer and the central controller, a transmission path identification is sent from the viewer's terminal to the central controller which indicates the particular video transmission path, e.g. trunk line and/or television channel, connecting the viewer to the central location. This path is then used to control the transmission of uniquely addressed viewo presentations from the central location to the viewer's terminal, where they are stored and retransmitted to the viewer's receiver.
