Abstract: Provided is a virtual world construction system that does not impair consistency between virtual worlds and places only small loads on terminals. A client application 10 that is implemented on a user terminal, a plurality of server applications 20 that are implemented on servers, and a proxy 30 that is located on a communication path between the user terminal and the servers and relays operation information and video information are provided. The proxy 30 includes a motion duplication unit 31 that transmits operation information to the plurality of servers by duplicating the operation information, and a video integration/rendering control unit 32 that transmits timing information regarding rendering timing to the plurality of servers, and transmits video information received from at least one of the servers, to the user terminals. A rendering processing unit/video processing unit 23 of each of the servers performs rendering processing and video information transmission processing based on the timing information received from the proxy 30.
