PROBLEM TO BE SOLVED: To simplify the operation of input/output means by providing a means for controlling the operation of a first display processing means or an image processing output means, or a second display processing means or an image processing means. SOLUTION: A first data transmission/reception terminal 52 performs three kinds of processings: outputting the video image of an object obtained from a camera 19 and the sound of an object obtained from a microphone 20 to a second data transmission/reception terminal 53; reproducing video and sound data received from the second data transmission/reception terminal 53 by the monitor 17 and speaker 18 of the first data transmission/reception terminal 52 which is a present terminal; and remotely operating an object data transmission/reception terminal based on a remote operation command outputted from a control terminal 56. The control terminal 56 is interposed between such plural data transmission/reception terminals 52 and 53. Based on an operation instruction by the sound outputted from a certain data transmission/reception terminals 52 and 53, one or plural data transmission/reception terminals 52 and 53 are controlled by the control terminal 56. |
