Abstract:
A method by which a universal controller emulates at least one control signal from each of a plurality of wireless transmitters, wherein each wireless transmitter controls at least one function of a respective system, further wherein at least one of the control signals from its respective wireless transmitter is an encrypted control signal and wherein decoding of the encrypted control signal is necessary for the encrypted control signal to be learned by the universal remote for later emulation, the method comprising the steps of:storing a plurality of codes in a memory of the universal controller, each of the plurality of codes associated with a decoding algorithm, wherein at least one of the decoding algorithms will enable decoding of the encrypted control signal;activating the wireless transmitter having the encrypted control signal so as to permit the universal controller to receive the encrypted control signal from the wireless transmitter;receiving the encrypted control signal, decoding the encrypted control signal and extracting digital sequences encoded within the control signal, the digital sequences being comprised of command instructions and security sequence information to operate a function of a corresponding one of the plurality of systems;storing the decoded command instructions and security sequence information in a selected memory location of the universal controller; andin an emulation mode:in response to a selection by the user of an emulatable wireless transmitter, retrieving the stored, decoded command instructions and security sequence information from the memory location corresponding to the selected emulatable wireless transmitter; andcontrolling the respective function of the corresponding system by transmitting at least the retrieved command instruction and security sequence information.
