PROBLEM TO BE SOLVED: To reduce a time required for transmission even when a high definition image is sent by conducting exclusive control in the case of sending the image data. SOLUTION: An image transmitter 110 gives the instruction of image transmission to an image transmitter 120. In this case, the transmitter 110 sends an exclusive command to the transmitter 120 and other image transmitters prior to start of transmission of image data. Upon the receipt of the exclusive command, each transmitter reaches the state of disabling transmission of its own command. Since the transmitter 120 and the other image transmitters cannot send their own commands, only the image transmitter 110 can send commands and data to the network. Thereafter, the transmitter 110 starts transmission of image data. |
