<p><P>PROBLEM TO BE SOLVED: To provide a system and a method which includes a polarity controller and a reverse circuit and automatically corrects wrong polarity in a communication signal. <P>SOLUTION: The system is provided with a video camera 14, camera controller 20 for controlling the video camera, transmission medium for communicating at least one polarity-sensitive signal between the video camera and the camera controller, polarity controller 12 for detecting the wrong polarity in the polarity sensitive-signal and supplying a reverse signal in response to the wrong polarity, and at least one polarity correcting circuit 22, 24 provided with a reverse circuit for reversing the wrong polarity in response to the reverse signal. Also, a circuit for correcting wrong wiring in transmission and reception connection is provided. This circuit is provided with a controller constituted so as to detect wrong connection of an input signal to at least one transmission terminal, responds to the wrong connection and supply at least one exchange signal, and a reverse circuit for responding to an exchange signal and exchanging a reception terminal and a transmission terminal. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
