Abstract
For optimum videotex data coding, for error-free functioning of so-called descramblers and—not least—for the impression of improved detail resolution on the screen of a television set of displayed pictures, it is known to process the video frequency response by influencing the higher frequency components in the video signal spectrum. According to the invention, adaptation to a video frequency response sought is in each case carried out automatically by means of corresponding shifting of the vision carrier relative to the IF total transmission curve. The respective adaptation for the relevant television channel of the set is effected, in principle, by the addition of a corresponding correction value to the corresponding channel tuning voltage of the tuner.
