摘要： When an A/D-converted composite video signal is directly outputted while a system clock frequency is switched so as to execute the determination of a signal system, a digital chroma demodulation system prevents the images displayed by the composite video signals from being distorted in accordance with a switching of the frequency of a system clock. The frequency m (=fsc×n) of the system clock is synchronized with a color burst signal and is set to fall in a predetermined range by changing a coefficient n in accordance with the system color burst signal freguency. Thus, since a composite video signal is A/D-converted in accordance with a substantially constant sampling frequency, the sampling condition such as a sampling frequency and a sampling point is not greatly changed.

This system includes a frequency-fixed oscillator oscillating at a frequency f0 sufficiently higher than a deflection frequency fh in a multi-scan display, a first counter for counting a clock outputted from said oscillator in a descending order, a duration in which an integer n which results from rounding a decimal point of a value obtained by a division of f0 fh is divided by an integer m smaller than n and said first counter counts a value k thus obtained k times is set to one cycle and a duration in which a second counter for counting a value m times repeats the counting m cycles is set to one period and thereby generating a deflection frequency fh.
