A virtual space control data receiving apparatus comprises stream data receiving means for receiving a plurality of stream data for controlling a dynamic virtual space, according to the type of each stream data; manual data input means for inputting control data for an object to be controlled in the virtual space; and control data output means for outputting the control data input by the manual data input means, for the object controlled by the manual data input means, and outputting the stream data received by the stream data receiving means, for the other objects. Therefore, in a dynamic virtual space represented by 3-dimensional CG, static image, dynamic image, audio, and text which are based on a network such as the Internet, the virtual space can be reproduced in real time, and the viewer can selectively control an object.
