    • The present invention aims at providing a DDNS server, a DDNS client terminal and a DDNS system which maintains high security while using DHCP and allows an access to terminals having the same IP address as well as data updates. The DDNS server includes a terminal management table storing the domain name, global IP address and port number of a DDNS client terminal, characterized in that the terminal management section checks whether a same global IP address is present in the terminal management table when a request to overwrite a global IP address is made from a DDNS client terminal and, in case the same global IP address is absent, permits overwriting of the global IP address, and in case the same global IP address is present, checks the port number, and in case the same port number is detected, inhibits overwriting of the global IP address, and in case the port number is different, permits overwriting of the global IP address.

    • In a CATV trunk amplifier, a downward signal input to an input terminal from the center equipment side is input to a downward amplifying circuit via a first filter and a second filter. The amplified downward signal is output to the terminal device side via the second filter, the first filter, and an output terminal. An upward L signal is input from the terminal device side via the output terminal to an upward L amplifying circuit via the first filter and a third filter. The amplified upward L signal is output to the center equipment side via the third filter, the first filter, and the input terminal. An upward H signal is input to an upward H amplifying circuit via a fourth filter. The amplified upward H signal is output to the center equipment side via the fourth filter and the input terminal.

    • A visual axis entry transmission apparatus and method enables a physically handicapped person who can not depress a foot button to easily transmit the selection of a character to be input. 50 characters are displayed, via a display controller, on the liquid crystal device of a head-mounted display unit and on an external monitor. The visual axis position of a user is detected by a visual axis detection circuit, and a character at the visual axis position is obtained based on the detected visual axis position data. Selection character data for the past 100 selections are then updated. When the condition for the entry of a character is satisfied by this new character selection, the character is added to an input character string, and the newly input character is pronounced to notify the user that the character entry has been completed. The visual axis position data are employed to determine the detection result, such as a condition where the visual axis detection was successful, the visual axis detection failed, the eyes were blinking, or the same option was selected. In accordance with the result of the determination, the color of the selection frame for a character is changed to provide the user detection result information that represents the detection result condition, thereby confirming the results of a detection of a line of sight and avoiding having to unnecessarily repeat an operation.
