A Combination Test Signal for Color Television Monitors
Color monitors are used for critical viewing in color television broadcasting and therefore must be routinely but carefully checked and if necessary be readjusted. Checking a monitor involves examining a large number of parameters (convergence, color temperature, phasing, gain and black-level setting, and a number of others), and at least three different test signals are normally required. It therefore seems reasonable to combine all the necessary test signals for all the parameters to be checked into one monitor test signal. Such a combination monitor test signal has now been developed; it requires only one channel and can be distributed readily throughout the broadcasting plant to be available whenever and wherever needed. Thus, because checking a color monitor is made easier, it is likely to be done more frequently, and this can result in an improved and more consistent broadcasting operation.
