First Claim
1. A home network system comprising:
- a plurality of home appliances that one of transmit and receive data over a power line communication network in a structure, said home appliances being controllable according to the data received over the power line communication network;
a plurality of power line modems connected respectively to said home appliances that modulate and demodulate data so that said home appliances can perform power line communications; and
a network master that assigns a home address to each of said power line modems and logical addresses to said home appliances, respectively, and that manages the data transmission and reception over the power line communication network.

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.

11. A method for operating a home network system, comprising:
-
a) determining whether a power line modem has a home address assigned thereto when newly connected to a power line communication network of the home network system, the power line modem being connected with the home appliance so that the home appliance can transmit and receive data over said power line communication network;
b) the power line modem transmitting a home address assignment request signal to a network master when it is determined to have no home address assigned thereto, the network master managing the data transmission and reception over the power line communication network; and
c) assigning, by the network master, a home address to the power line modem in response to the home address assignment request signal. - View Dependent Claims (12, 13)
