Abstract: Continuous wave signals synchronized with first chrominance subcarrier signals are generated (by means of a chrominance subcarrier extracting circuit (2), a phase error detecting circuit (3), an A/D conversion circuit (4), and a digital oscillation circuit (5)) from the analog video signals including the first chrominance subcarrier signals supplied to an input terminal (1). Digital video signals including chrominance components supplied to an input terminal (7) is converted into a composite video signal including chrominance signals (by means of a digital video signal converting circuit (6)). In this case, the chrominance components are converted into the chrominance signals by using the continuous wave signals, and the phase of the first chrominance subcarrier signals of the analog video signals is synchronized with that of the second chrominance subcarrier signals of the chrominance signals of the composite video signal produced from the digital video signals. Thus, the phase of the chrominance signals of the analog video signals can be synchronized with that of the chrominance signals of the composite video signal produced from the digital video signal, with, for example, a simple circuit constitution, and a picture drawn by the digital video signals can be easily combined with another picture drawn by the analog video signals.

Abstract: Signal processing apparatus for processing a color video signal formed of a luminance signal and a color carrier signal reproduced from a magnetic tape, in which the signals include respective crosstalk components produced from the tracks adjacent the track being traced. The color video signal was originally recorded so that the crosstalk components are frequency interleaved relative to the signal in the track being reproduced, and signal processing apparatus permits the luminance and color carrier signals to be processed and the respective crosstalk components eliminated using only a single time delay element for both luminance and color carrier crosstalk components. The single delay unit is part of a comb filter and is particularly adapted for fabrication as a CCD element.
