Abstract
The present invention relates a television system by which it is possible to obtain a wide picture with improved vertical resolution over the entire screen of a television receiver without deteriorating the picture quality by avoiding multiplexing of the high-frequency component of the side panel upon the broadcasting screen, and more particularly to a television system which transmits a television signal of having an aspect ratio of 9:16 by the same raster as that of a conventional type television signal with an aspect ratio of 3:4 and which minimizes the black band-like portions appearing upon the upper and lower portions of the screen of a conventional type television receiver.
