Abstract
A method for transmitting a color television signal between a transmitting station and a receiving station of a television system and for compatibly increasing picture resolution at the receiving station. In order to reduce crosstalk noise during motion adaptive picture processing of the color television signal with increased resolution, the following measures are taken: the offset modulation or offset sampling frequency is reduced; additional signals to increase resolution are limited in bandwidth at the transmitter; the chromaticity spectrum is obtained at the transmitter from a full frame sequence of the picture and is bandwidth limited at the transmitter in the direction of vertical spatial frequencies; the luminance signal and the additional signals are complementarily filtered at the receiver; and finally, at the receiver, the chromaticity spectrum is obtained from a full frame of the transmitted color television signal.
