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. The caption data storage unit is adapted to store the caption data corresponding to system manual guide information or an error message.
