    • An address-translating connection device which makes it possible to dynamically assign an IP address to a private address when a connection is made to inside of a LAN from outside. When an inquiry made by designating a host name as to a global address of the same is received from the first network, a private address-retrieving device looks up a host-name/private-address correlation storage device to retrieve a private address correlated to the designated host name. When a determining device determines that the address-correlation storage/translation device does not store a global address correlated to the retrieved private address, a storage device extracts an available one of global addresses to correlate the available global address to the retrieved private address, and cause the address-correlation storage/translation device to store therein the addresses correlated to each other. At the same time, a first notifying device sends out into the first network a reply notifying the global address stored.
    • 一种地址转换连接装置,其可以在从外部连接到LAN内部时将IP地址动态地分配给专用地址。 当从第一网络接收到对其全球地址指定主机名的询问时,专用地址检索装置查找主机名/专用地址相关存储装置,以检索与 指定的主机名。 当确定设备确定地址相关存储/转换设备不存储与所检索的专用地址相关的全局地址时,存储设备提取全局地址中的一个可用的全局地址以将可用的全局地址与所检索的专用地址相关联,以及 使得地址相关存储/转换装置在其中存储彼此相关的地址。 同时,第一通知装置向第一网络发送通知存储的全局地址的应答。

    • A terminal system having a video telephone equipment and a computer system. The video telephone equipment includes a communication unit connected to a line; a telephone unit for communicating with a remote station by speech via the communication unit and the line; and a camera unit for taking pictures and outputting video signals corresponding to the pictures. The video signals are transmitted to the remote station via the communication unit and the line. The video telephone equipment further includes a display unit for displaying images; and a processor for controlling the communication unit, the telephone unit, the camera unit and the display unit. The communication unit, the telephone unit, the camera unit, the display unit and the processor unit are coupled to each other by a first bus. The computer system includes a processor, coupled to an external unit by a second bus, for processing data supplied thereto via the second bus. The terminal system includes an interface circuit, coupled to the first and second buses, for intermediating between the video telephone equipment and the computer system so that data is transmitted from the computer system to the video telephone equipment via the interface means and vice versa.
    • 一种具有视频电话设备和计算机系统的终端系统。 视频电话设备包括连接到线路的通信单元; 电话单元,用于经由通信单元和线路通过语音与远程站通信; 以及摄像单元,用于拍摄和输出与图像相对应的视频信号。 视频信号通过通信单元和线路传输到远程站。 视频电话设备还包括用于显示图像的显示单元; 以及用于控制通信单元,电话单元,相机单元和显示单元的处理器。 通信单元,电话单元,相机单元,显示单元和处理器单元通过第一总线彼此耦合。 计算机系统包括处理器,其通过第二总线耦合到外部单元,用于处理经由第二总线提供给其的数据。 终端系统包括耦合到第一和第二总线的接口电路,用于在视频电话设备和计算机系统之间进行中介,使得数据经由接口装置从计算机系统发送到视频电话设备,反之亦然。
