ABSTRACT:
An infrared remote-control system and method for the simultaneous transmission of data from two or more separate hand transmitters to a single remote-control receiver is disclosed. Interference between transmitted signals is eliminated by interlacing control signals with quiescent periods during transmission. The control signals are received and validated by the receiver based on the quiescent periods.
