Abstract
PURPOSE: To obtain a high-contrast reproduction picture with a high resolution by recording previously the character picture frame in the black/white mode and then piling the specified color signal on the video signal reproduced at the reproducing time.
CONSTITUTION: Synchronous signal oscillator 24 delivers burst flag signal BFP, blanking signal BLK and synchronous signal SYNC each which are synchronized with video output PA. Phase shifter 28 shifts the phase of subcarrier oscillator 27 to obtain 7 different phase signals. Color signal switch 29 selects for output one of the color signal output of phase shifter 24 by the indication of color signal deciding unit 26. The color signal compounder unit generates the color signal of switch 29, the signal at the character signal part of luminance signal waveform shaping unit 25 and the color burst signal of color burst signal generator 30 as well as the noncomposite color video signal from signal BLK of oscillator 24. Compounder unit 32 compounds the video signal with signal SYNC and then delivers composite NTSC signal.
