Abstract: A server-client system and a method for operating the same are disclosed. A resolution server is provided to automatically store or update information regarding various resolutions of one or more client terminals connected to a wired/wireless network so that user interfaces appropriate respectively to the resolutions can be provided to the client terminals on the basis of the stored or updated resolution information. If the resolution information of any one of the client terminals connected to the wired/wireless network is automatically recognized, the appropriate user interface data is sent to the terminal on the basis of the recognized resolution information. Therefore, appropriate user interfaces can be provided respectively to client terminals having different resolutions according to manufacturers, models, functions, etc. thereof, thereby increasing convenience of users and reliability of the system.

Abstract: Disclosed herein are a home appliance network system and a method for operating the same. The home appliance network system comprises a plurality of home appliances connected to a network constructed in a home for transmitting and receiving data over the network, and a home server including a device monitoring module for independently storing and updating state information or product information of a specific one of the home appliances based on an input control command. When a user monitors product information of the home appliances to control the home appliances, the home server more rapidly displays the product information, resulting in an improvement in control speed. Further, the home server uses a smaller amount of network system resources, thereby enabling efficient networking to be made.
