Abstract
A device for use in an apparatus for demodulating the signal reproduced from a recording medium in a still video camera or the like in which the phase of the demodulated signal is always accurately detected. Horizontal periods in which the respective line-sequential color difference signals B-Y and R-Y are present are discriminated, and a timer is operated during periods when the B-Y signal is present. Data is read from the reproduced modulated signal at predetermined points within a half cycle of the waveform of the signal as designated by outputs of the timer.
