Abstract
In a color video information reproduction system such as video disc player and video tape recorder, the color burst signal is inserted into each horizontal period even during the vertical blanking period of a video information signal when the video information signal is recorded in order to obtain correct time axis variation information of a reproduced signal. Upon reproduction of the recorded video information signal, the color burst signal is separated from the reproduced signal and phase difference between the separated color burst signal and a reference signal is detected. The time axis servo system is driven on the basis of the detected phase difference and a stable and improved reproduced picture can be obtained while preventing an adverse influence to the audio information.
