ABSTRACT:
A recording signal generation system for a color video signal which is suitable for high density recording in a magnetic recording and playback apparatus. In each horizontal scan period which includes an effective horizontal scan period and a horizontal blanking period arranged serially on the time axis, a luminance signal is positioned in the effective horizontal scan period while, in the horizontal blanking period, compressed color signals generated by time-axis compressing color signals having a duration equal to the effective horizontal scan period by a predetermined ratio are disposed. The luminance signal and compressed color signals are time-division multiplexed. Special burst pilot signals are superposed on the multiplex signal each of which is separable from the compressed color signals and alternate with the other at an interval of one horizontal scan period, thereby discriminating the color signals from each other while indicating a position of horizontal blanking period. A carrier having a suitable frequency is frequency modulated by the superposed signal and the modulated output is used as a recording signal.
