Abstract
An apparatus and a method for providing remote control capability involves transmitting IR and RF signals in a time multiplexed manner. The present apparatus comprises an input device, an IR signal transmitter, a RF signal transmitter and a controller operatively coupled to the input device, the IR signal transmitter and the RF signal transmitter. The controller generates and applies the IR and RF signals to the respective signal transmitters in time multiplexed manner. The IR and RF signals may be transmitted using different protocols without significantly increasing the computing capacity of the controller as compared to a controller of a remote control device which transmits only one type of remote control signal.
