A Continuous Simplified Single-Line Color-Bar (SLCB) Test Signal Facility in Color Cameras

A continuous color test signal facility in the complex color-camera system is potentially a major contributing factor in the evolution of a uniformly satisfactory color broadcast system. Quality at present is not determined by the specific type of color system (NTSC, PAL, SECAM). It is determined by the actual maintenance and operation in the system used. For this quality control the simplified color-bar test signal has been devised. It is designated as the SLCB signal to distinguish this internal camera test signal from the general vertical interval test (VIT) signals used by broadcast networks for monitoring the cross-country microwave links and other video transmission systems. The SLCB signal facility is described as an adjunct to the automatic error-proof technique employed for its generation and insertion in the NTSC color signal.
