<p>Heretofore, it has been difficult to acquire a necessary image efficiently, when conducting remote supervision action via a network. Especially, it has been difficult to operate a remote device in synchronism with a supervisory image. In an image transmission system for transmitting a supervisory image via a network, a video monitoring equipment (201) is equipped with an image input section (204) for processing an input image, an image encoding section (205), an encoded image preservation section (210), an image communication section (207) for receiving a control request and conducting data communication, and an external device control section (209) for controlling a video output control device which effects input and output control of a plurality of images. As a result, it becomes possible to control devices from a client terminal (107) installed in a remote place, while watching the image.</p> |
