Abstract: A circuit and a method for generating a caption signal in a video signal processing system such as a video cassette recorder or a camcorder availably connected to a caption television. The circuit comprises a caption data storage unit for storing caption data into which a message to be displayed as a caption on a screen is coded, a caption microcomputer for reading the caption data from the caption data storage unit and generating a plurality of control signals, a caption code encoder for encoding the read caption data from the caption microcomputer into the caption signal under the control of the caption microcomputer and generating a caption region signal designating a region of a video signal into which the caption signal is to be combined, and a mixing unit for combining the caption signal from the caption code encoder into the video signal when the caption region signal from the caption code encoder is high.
