A remote control system has a remote controller and one or more controlled apparatuses, and a single operation of the remote controller by a user allows a series of functions to be continuously performed in the one or more controlled apparatuses. Upon operation of the remote controller by a user, the remote controller makes an inquiry about a current state of a controlled apparatus. In response to the inquiry from the remote controller, the apparatus sends a signal indicative of its current state. The remote controller then compares the current state of the apparatus with a desired state. The remote controller transmits a function control signal to the apparatus to instruct the apparatus to perform a required function only when the current state of the apparatus does not coincide with the desired state. The same function control signal is repeatedly transmitted until the current state of the apparatus coincides with the desired state.
