Abstract
An object of the present invention is to provide network devices and a network device control method which enable control network devices connected to an IP network, AV devices connected over 1394IF through gateway devices from the IP network, and home devices connected to ECHONET to be controlled without distinction among them. To achieve this object, a network device to serve as a controller comprises a controller application that detects a service of a target network device, using a message complying with an information exchange protocol common to the network, collects information such as an access method for the service, a function name, and parameters, and controls the network device upon request, and an information exchange protocol processing part that exchanges messages according to a protocol common to the network devices. The network device targeted for control comprises service that provides information for the controlling network device to perform control to the controller, and the information exchange protocol processing part.
