Abstract
When a client control apparatus on a network connects to a camera control apparatus in hyper text transfer protocol and requests the camera control apparatus to transmit a file of its home page, the camera control apparatus transmits a file, to the client control apparatus including a description for causing the client control apparatus to request the camera control apparatus to transmit an applet for performing automatic reception. When the client control apparatus receives this file, transmission of the applet is requested, and the server control apparatus transmits the applet. Then, when transmission of state information is requested, the server control apparatus transmits state information to the client control apparatus only when an event indicative of a change in an angle of a camera occurs; thereby traffic of the network is reduced.
