Abstract: Disclosed is a network control system for home appliances that satisfies the characteristics of low-cost and high-efficiency with respect to currently used appliances adopting a low-performance microcomputer. The system is constructed to define a master/slave type communication structure with respect to the respective appliances; construct a network by connecting the appliances through the serial communication function; and enable the appliances to communicate with one another if a predetermined communication event is produced. According to the system, an optimized network for the home appliances can be implemented, and operation states of the respective appliances can be displayed through the co-operation among the appliances, thereby maximizing the user convenience.

Abstract: The present invention relates to a home network management system, and more particularly to, connection handling, service management, and channel handling devices of a home network management system which can perform processing, conversion and transmission of data between a plurality of client devices and a plurality of home appliances. A channel handling device of the home network management system residing in a home master device connected to at least one home appliance through a first network and connected to at least one client device through a second network separated from the first network, and being controlled by a central processing means of the home master device, transmits/receives a first type of packet between a first device within the home master device and the home appliance.

Abstract: A method for detecting a communication speed of an apparatus is disclosed. The method includes a step for storing a communication speed which is currently used or a communication speed of one bit; a step for detecting a communication speed of received data by using data of a first frame which are first input among the received data; a step for detecting a consistent communication speed by comparing the detected communication speed and an initialized communication speed; a step for recognizing that a communication error is found if a consistent communication speed is not found as a result of said detection and for setting a consistent communication speed as a communication speed between the two apparatuses if a consistent communication speed is found; and a step for inputting the received data by using the set communication speed and performing corresponding commands.

Abstract: An apparatus and method for setting communication packet for a remote control between apparatuses is disclosed, which includes a communication port connected to an external apparatus by a communication bus, a communication circuit for converting signals transmitted/received by the communication port to signals appropriate for the communication bus, a memory for storing data information for communicating, and a microcomputer for controlling the communication circuit and the memory.

Abstract: A multipurpose remote controller and method for controlling the same is disclosed, which includes a user interface unit to which a control command signal is input by a user from outside, wire and wireless transmitting/receiving units for transmitting the control command signal input from the user interface unit to corresponding apparatuses, and for receiving operation state signals of the corresponding apparatuses, a central processor for controlling the user interface and wire and wireless transmitting/receiving units, a storage storing data for controlling the central processor, and a display unit for displaying control keys under control of the central processor and for displaying operation state and results.

Abstract: A communication apparatus and a method for supporting carrier sense multiple access/collision detection (CSMA/CD) are disclosed.

Abstract: An apparatus and method for converting communication protocol is disclosed, which is enable to communicate among apparatuses having different communication protocols by converting the different communication protocols into a protocol corresponding to one another. The apparatus includes a plurality of apparatuses having different communication protocols communicated in a bus line, and a converting apparatus connected to the plurality of apparatus for converting data input/output from an apparatus of a certain communication protocol by downloading communication protocol by Internet, or by mounting a card for converting communication protocol.

Abstract: A method for setting a product address in a home network system is disclosed. The method includes a step for requesting a temporary address in which a network controller designates redundant addresses with a predetermined range to each product and requests an arbitrary address among the redundant address as a temporary address; a step for designating a temporary address in which each product designates an arbitrary address among the redundant addresses as a temporary address and informs to a network controller; and a step for confirming an address in which the network controller sequentially sets one of the redundant addresses for each address not doubled among informed temporary addresses from each product.
