Abstract:
A display control system for simultaneously receiving control signals from a plurality of remote input control devices comprising:a first remote control device having a control element, for producing first control signals in response to manual input, and a transmitter which transmits a first carrier signal having a first frequency modulated by the first control signals;a second remote control device having a control element, for producing second control signals in response to manual input, and a transmitter which transmits a second carrier signal having a second frequency modulated by the second control signals;a receiver having a transducer for simultaneously receiving the first and second carrier signals and converting the signals into a composite electrical signal, a splitter for separating the composite electrical signal into first and second component signals having the first and a second frequencies, and first and second demodulators for deriving the first and second control signals from the first and second component signals, the first and second control signals controlling first and second display elements on a display device.
