Abstract: A relay server computer adds control code to background contents to generate web data for display engagement, and sends the generated web data to every client computer. The control code becomes a controller by executed on the client. When an object such as image is pasted on the background contents displayed in an engaged fashion, the controller detects the event occurred by pasting, and sends the information indicating the event to the other clients via relay server. Consequently, the screen with the object being pasted is displayed in an engaged fashion among all clients. The object can be moved, modified, or deleted.

Abstract: A relay server obtains web data including a motion picture from a WWW server, 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, and becomes a controller to control the browser in the same client. When one of the clients sends manipulating information indicating manipulation of the motion picture such as playback, stop, etc. to the relay server, the same relay server receive the manipulating information, and broadcast it to all of the clients including the sender. The controller of each client receives the manipulating information, and executes playback, stop, etc. in synchronization.
