Abstract

A watermark generator for providing a watermark signal in dependence on binary message data, the watermark generator has an information spreader configured to spread an information unit to a plurality of time-frequency-domain values, to obtain a spread information representation. The watermark generator also has a synchronization inserter configured to multiplicatively combine the spread information representation with a synchronization sequence to obtain a combined information-synchronization representation. The watermark generator also has a watermark signal provider configured to provide the watermark signal on the basis of the combined information-synchronization representation. A watermark decoder, methods and computer programs are also described.
