ABSTRACT:
A recording and reproducing apparatus for recording a video signal carrying a horizontal sync signal multiplexed with at least one another video signal into a serial mixed signal by compression along the time axis, or for recording such a signal without any compression along the time axis, wherein a pilot signal of a single frequency is superimposed in the horizontal blanking period of at least one video signal, and a clock is generated by use of the pilot signal of the mixed signal at the time of reproduction, thus eliminating time-axis variations appearing through recording and reproduction.
