Abstract
Inventive systems and methods for remotely controlling infrared controlled devices by using addressed radio frequency control signals. Radio frequency signals propagate through most obstructions to infrared control signals. Augmenting each control signal with an address allows for great selectivity in an environment with several transmitters and receivers.
