<p>A relay server (10) obtains web data including a motion picture from a WWW server (20), and embeds control code composed of a script or bytecode in the obtained web data to generate web data for synchronization. The control code is sent to each of clients (30), and becomes a controller to control the browser inthesameclient. When one of the clients (30) sendsmanipulating information indicating manipulation of the motion picture such as playback, stop, etc. to the relay server, the same relay server (10) receives the manipulating information, and broadcasts it to all of the clients including the sender. The controller of each client (30) receives the manipulating information, and executes playback, stop, etc. in synchronization.</p> |
