Abstract: A video processing system includes a plurality of identical video switch modules (A). Each of the video switch modules has matching inputs and outputs such that received signals can be passed through unchanged, enabling the modules to be connected in a daisy chain or series relationship. Each of the modules further includes inputs and outputs for receiving video signals from and sending video signals to procedure rooms (B). Preferably, each of the procedure rooms includes medical diagnostic apparatus (10-18) which produce one or more unprocessed video signals, a first video monitor (22) for displaying first processed video signals, a second monitor (24) for displaying second processed video signals, and a VCR (20) for recording and playing back second processed video signals. The daisy chain of video switch modules is interconnected at one end with a shared digital image processing system (C).
