Abstract
In a camera control system, a video sending terminal sends video from a video camera through a network to client terminals. The video camera is controlled by control commands from a client terminal which has been issued control from the video sending terminal in response to a request for control by the client terminal. The client terminal currently controlling the video camera is notified of a new request for control of the video camera made by another client terminal so that client terminals are notified of the locality of the video camera control.
