PURPOSE:To improve the reliability of the titled system by excluding a main data packet with a different address so as to prevent mis-control of main datapacket even if the main data packet comes at the reception side of a sub- data packet. CONSTITUTION:An address signal of a reception opposite party is sent together with a control signal to the sub data packet and the address signal is compared with the address of its own equipment at the reception side and only when both addresses are coincident, the control signal of the received packet is fetched. Thus, the main data packet and the sub data packet addressed to other device are excluded surely to receive the control signal only of the sub datapacket to its own device. Thus, the camera is controlled surely without mis-control at all times and the operating reliability of the system is enhanced. |
