Patent ID: 8332059

Claim:
An apparatus for synchronizing additional data and base data, the additional data and the base data comprising defined time courses and including data information that can be reproduced together, comprising: a provider for providing a test fingerprint of test data relating to a test time instant of the test data, with the test data being the additional data or the base data, or with the test data depending on the additional data or the base data; a determinator for determining reference time instant information dependent on a reference time instant in the reference data, the reference data being data from which the test fingerprint does not originate, using the test fingerprint; and a manipulator for manipulating the additional data or the base data, using the reference time instant information and test time instant information being dependent on the test time instant, in order to obtain manipulated data, wherein the manipulator is formed to manipulate the additional data or the base data so that a synchronous reproduction of the data information can be performed due to the manipulated data, wherein the provider is formed to provide a further test fingerprint relating to a further test time instant spaced apart from the one test time instant by a predetermined time distance, wherein the determinator is formed to determine further reference time instant information, using the further test fingerprint, wherein a further reference time instant comprises a temporal reference distance from the one reference time instant wherein the manipulator is formed to calculate a stretching factor or a shrinking factor due to the test distance and the reference distance, and temporally stretch or shrink the additional data or the base data, using this stretching factor or using this shrinking factor wherein the stretching factor indicates an amount by which a length in time of the additional data or the base data is different after a stretching operation, or wherein the shrinking factor indicates an amount by which a length in time of the additional data or the base data is different after a shrinking operation, wherein the manipulator is formed to calculate the shrinking factor or the stretching factor as follows: SS=ΔT ref /ΔT test , wherein ΔT test is a time difference between the one test time instant and the further test time instant, wherein ΔT ref is a time difference between a first reference offset Ta off and a second reference offset Tb off , wherein the first reference offset Ta off is obtained when the first test fingerprint is correlated with the reference signal, and wherein the second reference offset Tb off is obtained when the further test fingerprint is correlated with the reference signal, wherein the provider, the determinator or the manipulator comprises a hardware implementation.
