A system for automatically relating the changing information posted on an electronic display 10 a, in regard to some ongoing event, to the recorded information, such as video, captured and corresponding to that same ongoing event. Posted information is remotely detected using master camera 50 a that is aligned to capture images 12 of electronic display 10 a during the event. Current images 12 c are subtracted from base image 12 b to yield difference image 12 fr revealing one or more areas of potential electronic display 10 a changes that are pre-calibrated into cells, such as game clock 12 - 1 , which are further calibrated into characters, such as 12 - 1 - 1 for the "tens" digit through 12 - 1 - 4 for the "hundredths" digit. Using pattern matching algorithms well understood in the art, all changes to any character and therefore any cell are automatically detected and translated into digital information relatable by time to any recordings of the event, such as a video stream.
