Abstract: The Vertical Interval Test Signals (VITS) are useful for monitoring, measuring and/or correcting the performance of TV transmission systems while the systems are in service. The VIT Signals recommended by the Video Transmission Engineering Advisory Committee (VITEAC) have shortcomings in that they use up valuable “real estate” in the vertical interval and yet do not permit some of the more important parameters to be measured. The Omni-VIT Signal described in this paper uses only one TV line out of six available and yet permits the measurement of 13 transmission parameters, all of which are important for good color broadcasting. Since the Omni-VIT Signal uses only one line, it is possible to insert up to six signals at various points along a linked-up transmission path; thus it can be determined at the output of the system which of the links introduces excessive distortion.
