Moving-image data is streamed to a large number of client computers even though line band of a streaming server is kept narrow. To achieve this, the address of a relay server closer to a client computer than is the streaming server is transmitted when the client computer issues the streaming server a connection request for moving-image data. The client computer then sends this relay server a request to transmit the moving-image data. When this occurs, the address of another relay server even closer to the client computer than is the first-mentioned relay server is transmitted to the client computer. Since this other relay server is closest to the client computer, moving-image data is streamed from this relay server to the client computer.
