Abstract: The present invention relates to method and apparatus for interfacing for controlling a device between various applications operated on a home network and a library to ensure their compatibility. An interfacing method according to the present invention discloses processes to initialize a library being executed in a device for managing a home network, to set a home code for managing a home network exclusively, to manage address of each device on a home network, and to set conditions necessary for device monitoring.

Abstract: Disclosed herein are a wireless terminal-interoperable home network system and a method for controlling the same. A home server is linked with a security device and camera installed in a building to, when the security device senses entrance/exit of an outsider into/from the building, acquire an internal image of the building from the camera and send the acquired image to a wireless terminal of a user to enable the user to monitor the internal situation of the building in real time. The user can access the home server over a wireless communication network from a remote place outside of the building without separate access to the Internet to receive the internal image of the building and check the internal situation of the building on the basis of the received internal image, resulting in an increase in convenience of use.

Abstract: A home network system and a method for adding and/or deleting home appliances thereto/therefrom. The home network system is constructed so that a plurality of home appliances can transmit and receive data to/from one another. The home appliances are assigned logical addresses, respectively. A plurality of power line modems are connected respectively to the home appliances to modulate and demodulate data transmitted and received over an internal network by the home appliances. A network master is provided to assign the logical addresses to the home appliances and a home address to each of the power line modems, respectively. Therefore, the home network system can be efficiently constructed, and a desired home appliance can be simply deleted from the internal network.
