Method of and arrangements for coding and decoding color television signals using a separate series arrangement of a low-pass filter and a vertical temporal filter for each color difference signal

摘要

A color television transmission systems including three- dimensional filtering operations at the transmitter and receiver ends with the object of obtaining a lowest possible number of interferences in the form of cross color and cross-luminance on display in which each one of the two color difference signal channels has its own three-dimensional sub- filtering operation, wherein the two sub-filters are dimensioned differently.
