ABSTRACT:
A system is disclosed for providing programming and other information to television viewers for enabling them to control their respective television receivers. A central broadcasting computer and associated memory gathers and stores the information to be provided, and broadcasts it in a viewing area. An information receiver positioned in close proximity to the television is linked to said central broadcasting computer to receive signals representing said information from said central broadcasting computer. The received signals are converted video displays viewable on the television receiver's screen, and the user can use the displays to control the television receiver and other devices, such as video cassette recorders, used with the television receiver.
