Wireless video distribution system which avoids communication path congestion

A wireless visual communication system for distributing various video data to a movable terminal station by radio communication, said wireless visual communication system comprising:

• a video server for storing a plurality of types of video data;
• a base-station for video-data being connected with said video server through a network, for transmitting video data being supplied from said video server to said terminal station through a first radio communication path;
• and
• a base-station for control-data, for receiving a control signal being transmitted from said terminal station through a second radio communication path and for informing said video server of said control signal;
• wherein
• said terminal station is for announcing a request for video data and the type of said requested video data by transmitting said control signal,
• said video server is for retrieving corresponding said video data on the basis of said control signal being received from said base-station for control-data and outputting said video data on said network, and
• relatively wide and narrow bands are allotted to said first and second radio communication paths respectively;
• and wherein
• a plurality of said base-stations for video-data are provided with a specific communicable zone for each of said plurality of said base stations for video data respectively, and
• said base-station for control-data is communicable in an area covering said zones of all said base-stations for video-data.
