ABSTRACT:
A system and apparatus are provided for selectively terminating an analog video signal depending on whether or not a terminating device is present. A conditional terminator receives an analog video signal from a video input and terminates the video signal in the absence of a terminating device and does not terminate the video signal when a terminating device is connected to the analog video signal. A conditional terminator may comprise a resistor and transistor connecting the video signal to ground when a ground signal from a terminating device is not present and disconnecting the signal from ground as a result of the presence of a ground signal from a connected terminating device. The conditional termination may occur in a video input device or alternatively in a video cable connector.
