Automatic alignment techniques for color television manufacturing

A technique is proposed to align automatically a color television designed with a new family of integrated circuits that incorporate internal control registers which may be a set using a serial bus. Registers internal to the various components of the system store digital values which are converted by internal digital-to-analog converters to analog control voltages and currents. All of the registers can be modified by using a single microcomputer interface to the serial bus. A remote control receiver is available which also interfaces to the control bus. The main component of the system, a video/timebase processor integrated circuit, is a complete, highly integrated luma/chroma/deflection system with all necessary filters incorporated in silicon. The majority of the registers which are accessed for the final alignment are incorporated on this one IC. By using a video camera as the feedback element, a fast, accurate alignment of nearly all of the parameters adjusted during final factory test may be obtained
