PHN 13 017 18.11.1989 ABSTRACT Extended composite television system According to an aspect of the invention, the most perceivable interference patterns occurring during display of an extended television signal on a standard receiver are precompensated in an extended encoding apparatus, preferably in such a manner that an extended decoding apparatus may cancel this precompensation again According to a further aspect of the invention, the low-frequency luminance interference patterns at the encoding end are calculated by approximation, whereafter, on the basis of this knowledge, a low- frequency portion of a luminance signal is modified in such a manner that the low-frequency brightness variations caused by this modification compensate to the best possible extent the low-frequency brightness variations caused by the crosstalk of the additional signal.
