ABSTRACT In a chrominance signal demodulating system a locally regenerated chrominance reference signal is phase shifted to produce R-Y, G-Y and B-Y phase reference signals, which are applied to respective color difference signal demodulators together with the chrominance signal to be demodulated for producing demodulated R-Y, G-Y and B-Y color difference signals. The reference signal is at the "I" phase and is processed by an automatic flesh tone correction network responsive to chrominance signal phases in the vicinity of I phase.
