Abstract
An apparatus and method for controlling and detecting the alignment of a color frame phase from a composite analog video signal decodes the composite analog video signal to produce a component digital video signal and to generate a color frame signal that represents the start of each color frame for the composite analog video signal. Based upon the color frame signal a flag signal is inserted into the component digital video signal. The component digital video signal is captured by an analyzer based upon the flag signal so that the captured component digital video signal is in color frame phase with a stored reference component digital video signal. Preferably the stored reference component digital video signal represents a test sequence having an integer number of color frames plus or minus one video frame.
