The web server learns the operation of the remote controller by self-learning by matching a capture signal capturing an infrared ray signal with a control command, And controls the plurality of infrared ray control devices to be attached correspondingly.

The operation method of the web server provides an interface for initial setting of the operation of the remote controller to the external device through the interface providing unit and connects the communication network with the infrared control device selected by the user's selection input through the communication unit.

The web server can perform authentication based on the identification information on the user authentication received from the external device to provide an interface for initially setting the operation of the remote controller to the external device.

The operation method of the web server transmits a control command for the operation of the remote controller inputted through the interface providing unit to the selected infrared ray control apparatus and a learning completion message indicating that the self learning for the control command is completed from the selected infrared ray control apparatus through the communication unit .

The operation method of the web server repeatedly performs transmission of a subsequent control command and reception of a subsequent learning completion message indicating that the subsequent self learning has been completed, transmits the last control command, and registration of the operation of the remote controller When the registration completion message indicating completion is received, the communication network with the selected infrared ray control apparatus is disconnected.
