ABSTRACT:
When an intercom slave issues a call signal, all video terminals registered as terminals display images provided from the intercom slave. When an audio terminal responds to a call signal, control is performed to allow speech communications between the intercom slave and the audio terminal having responded to the call signal, to stop displaying of the images of the intercom slave by each video terminal and to cause the video terminal selected by the audio terminal to display the images. A combination of the selected video terminal and the audio terminal is registered. The audio terminals are displayed in a list form for selection. The video terminal receiving a radio wave with the highest intensity from the audio terminal is selected.
