1. A system for remotely controlling a plurality of devices responsive to transmitted multibit digital coded signals, with each device capable of performing a plurality of functions, said system comprising:

  • a plurality of user responsive selector means for generating binary digital coded control signals in response to a single user input, said coded control signals including address indicia for addressing a particular device and function indicia for controlling a particular function in said addressed device;

    first decoding means coupled to said selector means for receiving said coded control signals, said first decoding means responsive to said address indicia for generating a first signal for accessing only one of said plurality of devices;

    second decoding means coupled to said selector means for receiving said coded control signals, said second decoding means responsive to said function indicia for generating a second signal for controlling a particular function in said addressed device;

    ternary digital signal processing means coupled to said first and second decoding means and responsive to said first and second signals for generating a multibit coded ternary digital control signal in response thereto, said ternary digital control signal including said address and function indicia and comprised of a plurality of information elements having three possible states;

    transmitter means coupled to said signal processing means and responsive to said ternary digital control signal for generating and providing said control signal to said plurality of devices; and

    a timer circuit connected to said first and second decoding means, said ternary digital signal processing means and said transmitter means for providing clocking signals thereto in controlling signal flow therebetween.
