Abstract

A remote control system includes a plurality of control object terminals connected with the first network, a control server connected the first network and a second network to control the control object terminal and a remote control terminal connected with the second network. The remote control terminal issues a control request for a specific terminal of the plurality of control object terminals to the control server through the second network. The control server identifies the remote control terminal uniquely in response to the control request and carries out the control request in place of the remote control terminal when the remote control right of the specific terminal is allocated to the remote control terminal.
