Patent ID: 7886152

Claim:
A device for embedding watermark information into an information signal including audio and/or video information, comprising: processor for providing a synchronization sequence with a plurality of synchronization sequence units and a data sequence with a plurality of data sequence units, the data sequence being different from the watermark information, wherein between the data sequence and the synchronization sequence a time shift larger than or equal to zero is present and wherein a degree of the shift depends on the watermark information, wherein the processor is implemented to provide a data sequence which is different from the synchronization sequence; a first combiner for generating a combination sequence having a plurality of combination sequence units from the synchronization sequence and the data sequence shifted with regard to the synchronization sequence, wherein combination sequence units are derived from synchronization sequence units and shifted data sequence units; and a second combiner for combining the combination sequence and the information signal in order to embed the watermark information into the information signal.
