Systems and methods that allow the user to press one key on the device's remote to setup the IR codes for an AV device to be controlled by a universal remote control unit or centrally controlled by a television over IR blaster cables. In a preferred embodiment, the IR signal detection system of a television or a universal remote control unit is used to detect and learn the IR code corresponding to a single key, preferably the power key, on a remote control for the AV device to be controlled. Once the code corresponding to the key of the remote control unit pressed by the user is learned, the control system will search for a matching code in IR code tables stored in memory, which include IR code sets for different AV devices. Once a match is found, the control system will assign the corresponding code set to the AV device for future control.
