Abstract: A communication apparatus, which communicates with a host unit based on polling method, includes a control receiving unit that receives a control information to be transferred to the host unit from a user terminal, a request receiving unit that receives a request from the host unit to transfer the control information to the host unit, and a transmitting unit that transfers the control information to the host unit as a response to the request, provided that the control receiving unit receives the control information after the request receiving unit receives the request.

Abstract: The other communication devices are prohibited to transmit the address initialization request for a prescribed period of time since one communication device transmitted the address initialization request for an address managed by a control protocol, so that the conflict of the initialization requests for the same address will not occur and the problem of assigning the address in overlap to the communication devices will not arise. Also, the other communication devices are prohibited to transmit the the address server detection request packet for a prescribed period of time since one communication device transmitted the address server detection request packet, so that the conflict on the network by a plurality of address server detection requests will not occur, and it is possible to determine the MAC address server uniquely.

Abstract: A communication control device connected to a home network and an external network is formed by a control unit configured to give prescribed commands to home electronics devices through the home network; a Web server unit configured to provide an interface in a form of a Web screen for controlling one home electronics device requested by a terminal device, to the terminal device on the home network, and give a prescribed command for the one home electronics device given from the terminal device through the interface in a form of the Web screen, to the control unit; and an acquisition unit configured to automatically acquire a latest version of a file necessary in producing the interface in a form of the Web screen for controlling each home electronics device, from a prescribed server device corresponding to each home electronics device, through the external network.

Abstract: An apparatus and method for processing a Web page is disclosed. A Web processing unit receives a first Web page from a Web server and displays the first Web page on a screen. The Web processing unit acquires a communication program identified by the first Web page. An external state is monitored and thereby operation information responsive to the external state is generated. The Web processing unit executes the communication program to change the first Web page displayed on the screen to a second Web page according to the operation information.
