A charging device for charging a moving photoconductor. The charging device includes a charging member, an electric power supply for applying a voltage to the charging member, and a light exposing device, such as a LED for exposing surfaces of the charging member and the photoconductor in a closing region where the surfaces of the charging member and the photoconductor move closer to each other. The charging member is a blade having a transparent layer for guiding a light beam from the LED to the closing region and a shading layer for shading the light beam to a contacting region and a separating region. The contacting region is where the surfaces of the charging member and the photoconductor contact, and the separating region is where the surfaces of the charging member and the photoconductor gradually separate from each other. The LED is disposed in the vicinity of an end of the transparent layer opposite to the other end in the closing region in a section parallel to the moving direction of the photoconductor.

A broadcast receiving device capable of easily setting area information. A control unit of a DVR transmits an acquisition request for area information to a TV. When the control unit receives a response to the acquisition request from the TV, the control unit extracts area information from the received response and performs a channel presetting using the extracted area information. A control unit of the TV has area information stored therein. When the control unit receives an acquisition request for area information from the DVR, the control unit transmits, as a response to the request, the stored area information to the DVR.

A communication system includes a device and a server connected to the Internet, which transfers communications between the device and a terminal connectable to the Internet via the server. The device periodically transmits a notice packet to the server. The server transmits a connection request packet to the device in reply to the notice packet when a transfer to the device is requested from the terminal. The device transmits a TCP connection request to the server when receiving the connection request packet from the server. The server accepts the TCP connection request transmitted from the device to the server in reply to the connection request packet, to establish the TCP connection. Thus, the server transfers communications between the terminal and the device on the TCP connection after the TCP connection is established.

When pairing an AV device with a controller for linking to and controlling the AV device, it was necessary for the user operating the controller to select an AV device near the user in accordance with the position of the user. A controller 2 specifies a nearby device based on audio characteristic information (an audio fingerprint) generated from audio obtained by an audio input portion (microphone) or content information specified from such audio characteristic information, and audio characteristic information of devices obtained with a communication portion or content information specified from such audio characteristic information, to carry out the pairing.

The network system comprises an original device description indicating a control point so as to register an address used for MAC address authentication. The server side acquires information from the device(s) connected to the network, and only the device(s) having the above mentioned description are listed and displayed. By responding to the access from the non-registered device in a predetermined manner, the device is prompted to be registered, said device corresponding with the device description, but not registered.
