Abstract
A multi-commander includes a first memory for storing a plurality of remote control signals having different signal formats, a circuit for receiving a remote control signal from another remote commander, a rewritable second memory, a remote control signal transmitting circuit for transmitting a remote control signal derived from the first memory, and a mode switch for selectively switching between the setting mode and the remote control mode. When the mode switch is in the setting mode, the signal format of the remote control signal derived from the other remote commander and received by the remote control signal receiving circuit is identified and the signal format of the remote control signal from the other remote commander is read out of the first memory and is then written in the second memory. When the mode switch is in the remote control mode, the signal format written in the second memory is supplied to the remote control signal transmitting circuit in order to control a selected one of a plurality of electronic devices.
