Method and apparatus for the classification of television signals
First Claim
1. Method for the classification of television signals, characterized by the following steps:
- Defining a set of detectable features, each being characteristic of at least one property of said television signals;
Assigning a variable with a predetermined domain of arguments to each detectable feature;
Defining a predetermined functional domain for each detectable feature on said domain of arguments;
Defining a set of rule using said variables, wherein the evaluation of said set of rules results in a classification of said television signals;
Measuring said variables in said television signals for a predetermined time, andevaluating said rules using the measurement values of said variables to classify the content of the television signals.

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.
