Abstract

A wired telecommunications system for color television, in which, with respect to each of two color television transmissions, a transmitting apparatus serving to excite a respective conductive network of the system produces and applies to said network an information component of modulated carrier wave brightness and a modulated carrier wave color information component, the frequencies of said waves differing from each other at a frequency of approximately (see formula), where N is any integer and P is the scan frequency of lines, and means are included that determine that the carrier wave of the brightness information component that belongs to one of said transmissions has a frequency of about (N + 52/625) P and the carrier wave of the brightness information component belonging to the other transmission has a frequency of approximately (N + 260/625) P whereby the beating of these carrier waves or their harmonics occur at frequencies that differ from the fundamental frequencies of said carrier waves by a multiple of one-third or two-thirds of the line scan frequency of television signals and the visible effect of such padding on an image produced with help of these components.
