More details can be found on the NTSC video page. The three graphs on the left shows how the Y, U, and V component signals are decoded using the composite signal and a reference carrier wave. The polar graph on the right shows the resulting color phase and saturation of the decoded color. The Y component (shown in orange) is decoded by low passing or comb filtering the input signal.
