Zero Delay Video Systems

Robert J. Butler

A video source usually means a camera, video-tape machine or a film chain; but the video outputs of studios (not normally classed as video sources) are sometimes used as sources. If a studio is used as a video source, there are no pulse time delays which can make its video output synchronous with other sources. Building out the studio's active video path length to be equal to 1 H or multiples thereof, plus sync retiming, results in studio outputs which are effectively equal to zero.
