Device and Method for Analyzing an Information Signal
First Claim
1. A device 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 so that the sequence of blocks is represented by the sequence of fingerprints, comprising:
- a unit for providing identification results for consecutive fingerprints, wherein an identification result represents an association of a block of information units with a predetermined information entity, and wherein there is a reliability measure for each identification result, wherein the unit for providing is designed to generate a first identification result for a first fingerprint, and to generate a second identification result differing from the first identification result for a following block;
a unit for forming at least two hypotheses 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 a second hypothesis is an assumption for the association of the sequence of blocks with a second information entity, wherein the unit for forming is designed to start the first hypothesis or continue the already existing first hypothesis in response to the first identification result and to start the second hypothesis or to continue the already existing second hypothesis in response to the second identification result;
a unit for examining the at least two hypotheses by combining the reliability measures of the hypotheses to obtain an examination result; and
a unit for making a statement on the information signal based on the examination result.

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.
