Abstract
Equipment has been developed to synchronize color television sources so that they can be mixed and split-screened together at a central point. The system, which can work with any number of sources, controls the timing and phase of each source by error signals coded as audio tones which are generated by comparison equipment at the mixing point and carried by telephone bandwidth circuits. Part of the system, which was developed primarily for remote sources mounted in vehicles, is also being used within a studio complex in London to perform color-subcarrier phasing. The lock-up times of the various arrangements and the final accuracy required are discussed.
