Abstract
A wireless video terminal (17) creates a control signal for requesting video data. This control signal includes the type of the requested video data, a method of transmitting the video data, a position registration request and the like. The wireless video terminal (17) requests the video data by transmitting this control signal to a video server (11) through a base-station for control-data (19) and a network (13). The video server (11) transmits the requested video data to the wireless video terminal (17) requesting the video data through a designated channel, via the network (13), a router for video-data (14) and a base-station for video-data (15).
