要約
(EN)

A conferencing apparatus that is adapted to facilitate a video conference includes a first address information acquisition unit that acquires address information of a first processing terminal device which is connected to a first conferencing apparatus via a first local area network, a first address information notification unit that notifies both the address information of the first conferencing apparatus and the address information of the first processing terminal device to a second conferencing apparatus currently communicating with the first conferencing apparatus, and a first address information reception unit that receives at least address information of the second conferencing apparatus transmitted from the second conferencing apparatus. When the first conferencing apparatus receives a request message of start of sharing from the first processing terminal device, the first address information acquisition unit of the first conferencing apparatus acquires address information, and the first address information notification unit performs notification of the acquired address information. Therefore, conference materials can be output on display devices of the respective processing terminal devices of the participants in the video conference without requiring high level setting of the network. In addition, other participants can carry out interactive operations with respect to a material which is presented by a participant.
