HOME NETWORK SYSTEM

摘要

The present invention discloses a home network system (1) using a living network control protocol. The home network system (1) includes: at least two electric devices (40 to 49) (e.g., a first and a second electric device); and a network based on a predetermined network for networking the electric devices, wherein the first electric device (40 to 49) sends a request message to the second electric device (40 to 49), and the second electric device (40 to 49) sends a response message to the first electric device (40 to 49), wherein the response message transmitted from a lower layer to an upper layer of the second electric device (40 to 49) is transmitted to a lower layer and then to an upper layer of the first electric device (40 to 49) and includes a command code included in the request message, for indicating an operation for the second electric device (40 to 49) to execute, and a field related to an execution of the request.
