1. A method of controlling a remote television transmitter station to communicate television program material to at least one receiver station, said remote television transmitter station including one of a broadcast and a cablecast transmitter for transmitting television programming, a plurality of selective transfer devices each operatively connected to said one of a broadcast and a cablecast transmitter for communicating said television programming, a television receiver for receiving said television programming from at least one origination transmitter station, a control signal detector, and a controller capable of controlling said at least one of said selective transfer devices, said remote television transmitter station being adapted to detect the presence of a first control signal, to control the communication of said television programming in response to said first control signal, and to deliver at said one of a broadcast and a cablecast transmitter said television programming, said method comprising the steps of:

  • originating said television programming at said at least one origination transmitter station, said television programming including audio and a plurality of images to be outputted at said at least one receiver station in a predetermined sequence;

    originating said first control signal and a second control signal at said at least one origination transmitter station;

    originating at least one instruct signal at said at least one origination transmitter station;

    storing a programming schedule at said remote television transmitter station; and

    transmitting said television programming, said at least one instruct signal, said first control signal and said second control signal from said at least one origination transmitter station to said remote television transmitter station before a specific time at which said remote television transmitter station is to transmit said television programming and said at least one instruct signal;

    whereby, said first control signal is detectable by said control signal setector and instruct said controller to control said at least one selective transfer device to communicate said television programming to said one of a broadcast and a cablecast transmitter by comparing said stored programming schedule with said second control signal and in accordance with the result of the comparison to thereby control communication of said television programming and said at least one instruct signal from said one of a broadcast or a cablecast transmitter to said at least one receiver station at said specific time and said at least one instruct signal instructing said at least one receiver station to generate and output a computer generated output overlaid with said television programming at said at least one receiver station.
