Patent ID: 7539779

Claim:
A method for separating multi home networks, comprising the steps of: forming home network by interconnecting apparatuses in a house to communicate with one another; setting a home code for each apparatus networked in the home network, wherein the home code uniquely identifies the home network among a plurality of home networks, wherein said setting comprises: designating the home code and an apparatus code, that are pre-designated during a manufacturing process in a plant as a temporary apparatus code; comparing the designated temporary apparatus code with an apparatus code connected to a home network; if no apparatus having the same code with the designated temporary apparatus code exists, designating the designated temporary apparatus code to a corresponding apparatus as its own code, and then setting on the corresponding apparatus; if an apparatus having the same code with the designated temporary apparatus code exists, designating an arbitrary code randomly through an apparatus that controls a home network; and repeating the comparing step by using the designated arbitrary code as the designated temporary apparatus code until there is no identical code present; interconnecting the home networks formed for each house; and generating a packet data including the home code, and performing communication among apparatuses by using the packet data including the home code.
