ABSTRACT:
The present invention makes it possible for a user to share a virtual three dimensional space consisting of a plurality of media in a large wide-area network which includes a wide-band/high-speed network and narrow-band/low-speed network, without causing congestion in the network. The present invention include a multicast message transmitting unit and multicast message receiving unit for performing multicast communication in the wide-band/high-speed network, a unicast message transmitting unit and unicast message receiving unit for performing unicast communication in the narrow-band/low-speed network. A multicast group managing unit, multicast message generating unit and unicast message generating unit coordinate the unicast communication and the multicast communication. A message thinning/re-assembling unit reduces the communication traffic in the narrow-band/low-speed network, and the wide-band/high-speed network and the low-band/low-speed network are provided with respective terminals for sharing a three dimensional virtual environment.
