Abstract
A color picture information recording and reproducing system comprises a recording device for selectively recording color picture information and a pilot signal generator. In order to eliminate hue distortion of the reproduced color picture in case of selecting, recording, repeatedly reproducing and displaying a color picture signal of a single frame or a single field in a television broadcasting program or a still picture broadcasting program edited from different information at every frame or field, an input chrominance subcarrier and pilot signal of the output of a frequency locked signal generator are recorded on a record carrier together with an input color signal. The phase of the reproduced chrominance subcarrier is made continuous between adjacent frames or field by interleaving the pilot signal and a relation of frequency interleaving is maintained so as to eliminate phase jitter. The pilot signal generator is always frequency locked by means of another synchronizing signal having a frequency which is in a certain relation with that of the chrominance subcarrier.
