    • When a line for communication of audio signals between first and second portable-telephone devices through a first portable-telephone base station, a second portable-telephone base station and a portable-telephone line network has been connected, IP addresses are exchanged. The IP addresses are required for communicating image data by first and second terminal adapters associated with the first and second portable-telephone devices respectively through an OCN. Image data is then transmitted to the IP addresses received in the communication through the OCN. To put it concretely, an image of the user of the first portable-telephone device is transmitted by the first terminal adapter through the OCN to the IP address of the second terminal adapter to be displayed by a second television receiver associated with the second terminal adapter. By the same token, an image of the user of the second portable-telephone device is transmitted by the second terminal adapter through the OCN to the IP address of the first terminal adapter to be displayed by a first television receiver associated with the first terminal adapter. Thus, by merely taking a portable-telephone device to a place like a store selling home electrical appliances including a television.
    • 当通过第一便携式电话基站,第二便携式电话基站和便携式电话线路网络连接第一和第二便携式电话设备之间的音频信号的线路时,交换IP地址。 需要IP地址来分别通过OCN与第一和第二便携式电话设备相关联的第一和第二终端适配器通信图像数据。 然后,图像数据通过OCN发送到通信中接收到的IP地址。 具体地说,第一便携式电话设备的用户的图像由第一终端适配器通过OCN发送到第二终端适配器的IP地址,以由与第二终端适配器相关联的第二电视接收机显示 。 同样,第二便携式电话设备的用户的图像由第二终端适配器通过OCN发送到第一终端适配器的IP地址,以由与第一终端适配器相关联的第一电视接收机显示 。 因此,通过仅将便携式电话设备带到诸如出售包括电视在内的家用电器的商店的地方。
