| 摘要 |
The color video information signal source (1a, 1b) including the modulation circuit network (3a, 3b, 3c, 4a) of providing modulated negative carrier wave signal of the first phase (R-Y) and the second phase (B-Y), the first output terminal (Y) providing luminance component of prescribed frequency band width, the signal combination circuit (5C) connected to the first and the second output terminal, the signal record (10) connected to the output of the frequency modulator are included in the video disc systems. The characteristic of the systems is the burst-pulse generating circuit (26).
