    • A video-phone call with a portable video-phone terminal is enabled for a cellular phone which has not video-phone service provided, by making use of cameras and display devices placed on the street. For a video-phone call to a portable video-phone terminal, a media converter in a service center distributes data so as to send video data to a public communication terminal on the street, and voice data to a cellular phone without video recording/reproducing capability. A call agent in a service center issues an ID in response to a request from the cellular phone without video recording/reproducing capability on voice call. This ID may be received by a service center via a detector such as a sensor deployed on the street, to provide a video-phone service by using a public communication terminal on the street in the vicinity of the detector.
    • 通过使用放置在街道上的相机和显示设备,可以为没有提供视频电话服务的蜂窝电话启用具有便携式视频电话终端的视频电话。 对于对便携式视频电话终端的视频电话呼叫,服务中心的媒体转换器分配数据,以将视频数据发送到街道上的公共通信终端,并将语音数据发送到蜂窝电话而不进行视频记录/再现 能力。 响应于来自蜂窝电话的请求而在语音呼叫中没有视频记录/再现能力的情况下,服务中心的呼叫代理发出ID。 该ID可以由服务中心经由诸如部署在街道上的传感器的检测器接收,以通过使用在检测器附近的街道上的公共通信终端来提供视频电话服务。
