Abstract

The invention relates to the classification of such parts of television signals which are commercials so that those parts can be eliminated during recording or playback. Known methods for the detection of commercials during a TV program suffer from the drawbacks that one or two features of the TV signals are observed to decide whether the TV signal is part of a commercial or not. In the present invention of a method and apparatus, a classification of TV signals results on a plurality of information gathered from the TV signals and a plurality of rules using a rule system. Such a rule system permits the modeling of uncertainties so that for the definition of the rules, no strict values or strict limits need be given. In particular, fuzzy rules and linguistic variables are used.
