ABSTRACT:
In an apparatus for reproducing, from a record medium, a recorded video signal including an FM-modulated luminance signal and a chroma signal which is down-converted from an original frequency band; the FM-modulated luminance signal reproduced from the record medium is demodulated and than the time-base of the demodulated luminance signal is corrected, whereas, the time-base of the down-converted chroma signal reproduced from the record medium is corrected and then the reproduced chroma signal is up-converted to its original frequency band. A servo circuit, for example, for controlling the rotary drum motor and/or the capstan motor of a video tape recording/reproducing apparatus (VTR) during a reproducing operation, is controlled in response to a phase difference between write and read addresses applied to a memory of the time-base corrector so that such memory can be provided with a relatively small capacity.
