Apparatus for Determining Information in Order to Temporally Align Two Information Signals

A method of 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 method comprising:

• 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 being extracted from a plurality of characteristics 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
• determining the information for temporal alignment on the basis of similarities between the first and second characteristic curves of the characteristic by means of a first search for a search pattern from one of the first and second characteristic curves of the characteristic within the other of the first and second characteristic curves of the characteristic.

A computer program comprising a program code for performing the method of 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 method comprising:

• 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 being extracted from a plurality of characteristics 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
• determining the information for temporal alignment on the basis of similarities between the first and second characteristic curves of the characteristic by means of a first search for a search pattern from one of the first and second characteristic curves of the characteristic within the other of the first and second characteristic curves of the characteristic,
• when the computer program runs on a computer.
