<P>PROBLEM TO BE SOLVED: To solve the problem wherein an existing network or an official network service cannot use multicast distribution substantially, because an apparatus with higher distribution capability for providing images is needed, load is imposed on network paths, and it is difficult to provide homogeneous images because of the matter of distribution capability when an identical image data is needed at a plurality of places or distribution using wide area network services is required, furthermore, expensive concentrators and skilled network engineers are required if multicast distribution is performed in order to provide homogeneous images, hence, it has great influence on work cost or reconfiguration time duration. <P>SOLUTION: Image data of only one system are received from a source. While reproducing and re-distributing the image data to a request source, individual system is re-distributed to a plurality of request sources, respectively. <P>COPYRIGHT: (C)2009,JPO&INPIT |
