Device and method for producing a data flow and for producing a multi-channel representation

to temporal synchronization of a data stream with multi-channel additional data and a data stream with data on at least one base channel is on encoder currently-side for at least one base channel performed a fingerprint-information-calculation to the fingerprint information in temporal relation to the introduce multi-channel additional data in a data stream. On the decoder side are Fingerprint information from the at least one base channel calculated together with the extracted from the data stream fingerprint information used z. B. by correlation a time offset between the data stream with the multi-channel additional information and the data stream with the calculated at least one base channel to compensate for and to a synchronized multi-channel representation to obtain.
