Abstract: Disclosed is a server system for performing communication over a wireless network. At least one client device transmits and receives data over the wireless network. A server device performs a state monitoring or controlling operation for the at least one client device. In the server device, an encoder compresses and encodes data to be transmitted that includes a double buffer storing the encoded data. A network renderer transmits the data encoded by the encoder to a corresponding client device over the wireless network. A buffer manager detects an overflow of the buffer storing the data encoded by the encoder and issues a control signal for pausing an encoding operation when the overflow is detected. Therefore, the server system can avoid data loss and system shutdown caused by transmission delay and can ensure stability of the server system performing communication with a wireless network.

Abstract: A media streaming home network system including at least one media client, which requests for a media streaming service through the Internet under a dynamic or static Internet Protocol (IP) environment, a media server, which detects network address information from the media client or a gateway connected to the media client, performs an access authentication process for the media client, and provides the media streaming service requested by the media client when the media client is authenticated, and a control server, which relays control messages transmitted between the media client and the media server, and provides the network address information of the media client to the media server.

Abstract: Disclosed are a server system for performing communication over a wireless network and a communication method thereof. The server system comprises at least one client device and a server device for performing a state monitoring operation or a control operation for the client device over the wireless network. When a data packet is sent, the server device begins to send a following packet by variably applying a transmission rate according to a network transmission state when a leading packet has been completely transmitted. Because a transmission rate can be set appropriately to the network state, the number of unnecessary retransmissions can be reduced. Therefore, transmission delay can be avoided and stable and rapid wireless communication can be achieved.

Abstract: A television-watchable refrigerator system and a method for operating the same. A Web pad is detachably mounted on the outer surface of a refrigerator and a television (TV) module or TV antenna module is provided to receive a television signal and wirelessly transmit the received television signal to the Web pad, thereby removing a need for wiring to provide a wired connection of the refrigerator with a television antenna terminal. The TV module or TV antenna module is connected with a television set or television antenna terminal to receive a television signal therefrom and wirelessly transmit the received television signal to the Web pad. The Web pad is detachably mounted on the outer surface of the refrigerator to wirelessly receive the television signal from the TV module or TV antenna module and display it.

Abstract: A system and method for switching a communication mode of a detachable pad refrigerator, wherein the attachment/detachment of a client pad to/from the refrigerator is sensed and the communication mode of the refrigerator with the client pad is switched to a wired/wireless communication mode according to the sensed result so that signals can be transmitted and received in the switched communication mode. The client pad is detachably attached to the outer surface of the refrigerator. A communication module is installed in the refrigerator to transmit and receive signals to/from the client pad by wire or wirelessly. A refrigerator control unit is adapted to control the communication module to automatically switch the communication mode of the refrigerator with the client pad to the wired/wireless communication mode according to the attachment/detachment of the client pad.

Abstract: An Internet refrigerator with a Web pad and a method for operating the same. The Web pad is detachably mounted on the Internet refrigerator, and transmits and receives data to/from the Internet refrigerator on the basis of a remote display protocol (RDP). The Web pad is a client Web pad detachably mounted on an outer surface of the Internet refrigerator. The client Web pad is adapted to receive a display signal transmitted from the Internet refrigerator and output the received display signal externally. A server control unit is provided to transmit the display signal to the client Web pad on the basis of the remote display protocol such that data processed in the Internet refrigerator is displayed through the client Web pad. Application programs and multimedia data are driven on the basis of the server control unit, resulting in a reduction in work-load on the client Web pad.

Abstract: A networking system for a refrigerator is provided. The networking system includes a main controller for the refrigerator coupled to a first terminal provided on a body portion of the refrigerator, and a second terminal provided on the refrigerator door. The second terminal allows information related to the refrigerator to be input and received, and allows for wireless data exchange between the main controller and the first terminal such that the second terminal to be separated from the refrigerator and still perform such a data exchange. The use of a main controller and first and second terminals allows for increased levels of data storage, and easy access to various types of information.

Abstract: An Internet refrigerator with a heat sink uses cold air from the Internet refrigerator itself, without a CPU cooling fan on a main board. The Internet refrigerator includes a main board with a chip set thereon and a temperature sensor that detects a temperature of the main board. A heat sink plate faces a surface of the main board and absorbs heat generated from the chip set. A pipeline having both ends connected to an interior of a cooled compartment of the refrigerator is arranged to contact a lower surface of the main board at a portion thereof. Additionally, a cooling fan can be arranged in the cooled compartment of the refrigerator for introducing cold air from the cooled compartment of the refrigerator into the pipeline.

Abstract: A method for operating a home network system which can allow a home server appliance to assign, to a client appliance newly connected to a home network, a unique ID (Identifier or Identity) different from IDs assigned to already connected client appliances, such that all home appliances connected to the home network can be appropriately controlled. As a unique ID is assigned to the client appliance newly connected to the home network so that the newly connected client appliance is automatically bound to the home network, it is assured that different IDs are assigned to the client appliances, made by different manufacturers, connected to the home network. Therefore, a plurality of client appliances can be appropriately discriminated and controlled and the reliability of a control operation can be improved in the home network system.
