Abstract

PURPOSE: To simplify and miniaturize an encoder by applying a color difference signal and burst flag signal to modulators at the same time in the color encoder.
CONSTITUTION: Color difference signal C-Y, and burst flag pulse BF and color difference signal B-Y are applied to modulators 34 and 35 via respective terminals 31 and 32 at the same time for balanced modulation. In order to remove unneeded signal components during a blanking period except a bust-signal period, modulators 34 and 35 are applied with blanking pulse BLK with the component in the bust signal period removed, thereby inserting blanking pulse BLK into a chrominance signal.
