Abstract: A communication between a terminal connected to the Internet, like a household terminal, and a server can be performed by simple processing at any time after security is ensured. In a case where control of a particular terminal connected to a predetermined network is performed from the server, when there is a predetermined processing request at the particular terminal from the server or an external terminal connected to the server, a callback request is sent to the server or the particular terminal. At the particular terminal receiving the callback request, a callback request response is made to the server by a predetermined communication method in which security is ensured, and instructions for performing predetermined processing by the predetermined communication method are sent, as a response from the server with respect to the callback request response, to the particular terminal.

Abstract: Various electronic equipments used in a network conferencing system are integrally managed and presentation is made in a simple manner. When each attendant electronic equipment becomes a chairman terminal having an equipment management function, it inquires the availability of an electronic equipment used for a conference, then obtains information related to an available equipment from a client control section of a conference management server, and determines whether the electronic equipment used for the conference is an output electronic equipment such as a projector or a generating electronic equipment such as a scanner. Thus, an icon display of the generating electronic equipment and an icon display of the output electronic equipment are provided while separating an area for the icon display of the generating electronic equipment and an area for the icon display of the output electronic equipment, by the display function of each attendant electronic equipment.
