SIDE PANEL SIGNAL PROCESSOR FOR A WIDESCREEN TELEVISION SYSTEM

摘要

RCA 86,235 In a television signal processing system of the type which encodes an auxiliary carrier modulated with auxiliary image information in line format, which carrier is placed within the spectral band of standard television signal components, and wherein the modulated auxiliary carrier tends to interfere with the standard television signal, the interference is minimized by spatially variably attenuating the auxiliary image information. The attenuation function is selected to apply greater attenuation to the auxiliary image information at the extremities of the lines than toward the center of the lines.
