ABSTRACT:
A video signal reproducing apparatus is provided with delay means for changing to a given degree at a time the phase of a reproduced horizontal synchronizing signal included in a reproduced video signal which is taken out from a recording medium. When the reproduced horizontal synchronizing signal becomes discontinuous, the discontinuous signal is replaced with the output signal of the delay means until the phase of the output signal comes to coincide with the phase of the reproduced horizontal synchronizing signal. The delay means includes a delay line which delays the horizontal synchronizing signal for one horizontal scanning period and a delay circuit which is arranged to further delay for a short period of time the signal delayed and produced from the delay line.
