Conference system, event management server, and program

摘要

A conference system includes a first conference device (12) and a second conference device (11) installed at a first site (A), and is connected with an external conference device (21) installed at a site (B) different from the first site (A). The second conference device (11) selects one from a group consisting of a video image taken by and received from the first conference device (12) and a video image taken by the second conference device (11) to transmit the selected video image to the external conference device (21). The second conference device (11) selects a video image taken by the second conference device (11) when the second conference device (11) detects an event occurred at the second conference device (11).
