ABSTRACT:
In transmitting, for example, by recording and reproducing, fields of video signals each having a core portion and side portions adjacent to such core portion and comprised of luminance and chrominance signals, the luminance signal which is desirably frequency modulated and the chrominance signal which is desirably frequency converted to a lower frequency band are combined and transmitted or recorded during the core portion of each field to provide a display of increased aspect ratio, and the chrominance signal is decoded into color difference signals which are time-compressed and then frequency modulated prior to being transmitted or recorded during the side portions of each field for enhancing the color of the displayed picture.
