Abstract

For analyzing an information signal having a sequence of blocks of information units, wherein a plurality of consecutive blocks of the sequence of blocks represents an information entity, using a sequence of fingerprints for the sequence of blocks, identification results are provided for consecutive fingerprints, wherein an identification result represents an association of a block of information units with a predetermined information entity. Then at least two hypotheses are formed from the identification results for the consecutive fingerprints, wherein a first hypothesis is an assumption for the association of the sequence of blocks with a first information entity, and wherein the second hypothesis is an assumption for the association of the sequence of blocks with the second information entity. Then various hypotheses are examined to obtain an examination result on the basis of which there is then made a statement on the information signal. This achieves a meaningful and reliable time-continuous analysis of an information signal.
