Abstract
PURPOSE: In recording and reproducing of PAL-system color image signal, the phase of carrier chrominance signal is shifted to a fixed direction by nearly 90 degrees with every horizontal period. In this way, the crosstalk is eliminated at reproducing time, at the same time increasing the sue efficiency of record medium.
