Claim One:
1. An apparatus for determining information in order to temporally align a first information signal and a second information signal, each of which comprises one or several information values for successive sampling times, the apparatus comprising a characteristic extractor for extracting a characteristic per sampling time or per subsequence of sampling times of the successive sampling times from the first information signal within a first search pattern so as to obtain a first characteristic curve, and for extracting the characteristic per sampling time or per subsequence of sampling times of the successive sampling times from the second information signal within a second search pattern so as to obtain a second characteristic curve, the characteristic extractor being configured to extract the characteristic from a plurality of characteristics per sampling time or per subsequence of sampling times, so that the characteristic comprises characteristic properties which by comparison with characteristic properties of other characteristics indicate an increased level of success in the search for the search pattern from one of the first and second characteristic curves of the characteristic; and a determiner for determining the information for temporal alignment on the basis of similarities between the first and second characteristic curves by means of a first search for a search pattern from one of the first and second characteristic curves within the other of the first and second characteristic curves.
