Disclosed are a remote control system for a home appliance network and a method for operating the same. The system includes a wired and wireless Internet network; at least one home server for controlling and managing a home network connected to a plurality of home appliances; and a central portal server for updating an IP (Internet Protocol) address to a varied IP address to manage the home server whenever an IP address allocated to the home server for using the Internet network varies, and for exchanging data with the home server. The system and method enable the central portal server to manage a plurality of home servers and remotely control a plurality of home appliances connected to the home network by allowing the home server to transmit a key message containing a varied IP address so that an existing IP address stored in a database of the central portal server can be updated to a new IP address when a home server using a dynamic IP is connected to the central portal server.

Remote control system for home appliance network and method for operating the same

A system and method for providing home appliance control data, wherein a Java phone allows a user to select desired control data to be transferred to a home appliance from among a plurality of control data, and a control data provision server downloads to the Java phone the control data selected by the user and a Java application for execution of the selected control data at the same time. The Java application and the control data are downloaded through a one-time operation based on the user's selection, thereby reducing the number of Internet accesses and an Internet access time for downloading of the control data to the home appliance. Therefore, the control data can be transferred to the home appliance within a shorter period of time, resulting in curtailment of a communication fee to be paid.

System and method for providing home appliance control data

A system and method for transferring home appliance control data, wherein a control data provision server stores a plurality of data for control of a home appliance and a unified Java application for execution of the plurality of control data. The control data provision server stores the same number of Java applications as that of a plurality of Java virtual machines contained respectively in a plurality of Java phones, resulting in no necessity for each Java phone to download respective Java applications whenever downloading respective control data. Therefore, the control data provision server can be reduced in capacity and burden thereon, and in turn in construction and maintenance costs.
