<P>PROBLEM TO BE SOLVED: To improve the reliability of a system and to ensure the stability of communication or the like by dual (redundant) operation support servers, and to smoothly continue a conference without interruption by automatically switching the operation support servers. <P>SOLUTION: Multiple operation support servers are provided, each including a synchronization function which synchronizes site connection information and live camera information between the respective operation support servers and prevents the operation support server in a standby state from writing the live camera information in a folder for each site. Each site PC 14 includes an automatic server change function which, when the operation support server 11 in service fails, switches connection to the operation support server 12 in a standby state. When the operation support server in service fails, the operation support server in a standby state writes live camera information into a folder for each site and each site PC changes connection from the operation support server that was in service to the operation support server in a standby state. <P>COPYRIGHT: (C)2010,JPO&INPIT |
