ABSTRACT:
In digitally recording a color video signal for a SECAM system, a horizontal blanking interval including a horizontal synchronizing signal and a non-modulated carrier is not recorded as in the case of a color video signal for a NTSC or PAL system. In a reproducing mode, the non-modulated carrier is restored from the reproduced data and then is inserted in the horizontal blanking interval with the horizontal synchronizing signal, thereby reducing the amount of information to be recorded.
