发明名称 Video processing circuit
摘要 A video processing circuit for receiving a video signal from a tuner or a video recording/reproducing apparatus through a first or second input terminal and for outputting the video signal as it is through an output terminal under one condition and outputting a character signal from a signal source thereof instead of the video signal through the output terminal or outputting the video signal with the character signal superimposed thereon from the output terminal under the other condition. In the video processing circuit, among a plurality of circuits interposing from the first and second input terminals to the output terminal, only circuits related to the signal source of the character signal are formed in one integrated circuit (second integrated circuit) and the other circuits are formed in the other integrated circuit (first integrated circuit).
