发明名称 Interactive cable television system without a return path
摘要 A method for providing interactive information content in an analog cable system having only a one-way communication path from a cable head end to a communication device, such as a set-top box that is associated with a television is disclosed. A set-top box receives a plurality of interactive information content signals on at least one analog channel from the cable head end. In certain embodiments the interactive information content signals are data streams that sent over an analog carrier channel. The set-top box provides a selection screen to the television for display. A user can then use a user-input device, such as, a remote control to make a selection. In general, the user will select a key, such as a directional key and the remote control will provide the selection/directional signal to the set-top box. The set-top box then outputs a new information content signal based the received selection signal without having to transmit to the head end.
