Abstract : An event scoring using a video mulitplexer and method are created by using a plurality of video cameras to cover limited fields of view of a given area. The cameras are distributed to cover the area. The video output of the cameras is used as input to a video multiplex circuit which multiplexes the camera video signals to form a composite signal containing the desirable information from each camera and generated the sync signal for the slave camera. By counting horizontal lines of video and video sync levels, selected lines of video are combined to form a composite video image. The composite video image permits both a target and a strike event to be recorded in a least two locations within the composite video. A scoring systems inputs the multiplexer output to determine the miss distance and direction from the target. A programmable read only memory permits one of the camera video inputs to be a gray level which is inserted between consecutive camera lines of actual real time video signal. These gray level stripes provide ease in identifying which horizontal lines are producing a given effect. (Patent)
