发明名称 Video reproducing apparatus
摘要 A video reproducing apparatus adapted for reproducing a television signal of two or more television standard systems, comprising signal extracting means (3a, 3b) for extracting a video signal from a recording medium (1) for providing a reproduced signal (S1), a color signal processing means (11) for processing a color signal in the reproduced signal (S1) for adapting the same to the respective television standard systems, a color reference signal generating means (10) for generating a color reference signal (S6) of the frequency associated with each of the respective television standard systems, a frequency dividing means (8, 15) for frequency dividing the color reference signal (S6) for generating a vertical reference signal (S5) of the frequency associated with each of the television standard systems, and switches (SW1 to SW3) for selecting each of the respective television standard systems. The vertical reference signal (S5) is generated without providing a discrete oscillating circuit but rather by frequency dividing the color reference signal (S6). Accordingly, the number of components can be decreased and the frequency relation of both signals is maintained constant, whereby any undesired phenomenon is prevented from occurring.
