Abstract: In a PAL color television system for processing a color signal including burst and chrominance components alternating in phase at the image line scanning rate, identification and control circuitry for rapidly correcting an incorrect mode of line to line color demodulator switching. A bistable circuit generates timing signals for controlling line by line switching of a selected color demodulator(e. g., R-Y). An identification signal representative of an incorrect line switching mode is derived from information contained in the burst component, and serves to reset the bistable circuit such that timing signals corresponding to a correct switching mode are produced.
