| titleOfInvention | Watermark signal provider and method for providing a watermark signal |
| abstract | A watermark signal provider for providing a watermark signal in dependence on a time frequency-domain representation of watermark data, in which the time-frequency-domain representation comprises values associated to frequency subbands and bit intervals, the watermark signal provider comprises a time-frequency-domain waveform provider to provide time-domain waveforms for a plurality of frequency subbands, based on the time- frequency-domain representation of the watermark data. The time-frequency-domain waveform provider is configured to map a given value of the time-frequency-domain representation onto a bit shaping function. A temporal extension of the bit shaping function is longer than the bit interval associated to the given value of the time-frequency-domain representation, such that there is a temporal overlap between bit shaped functions provided for temporally subsequent values of the time-frequency-domain representation of the same frequency subband. A time-domain waveform of a given frequency subband contains a plurality of bit shaped functions provided for temporally subsequent values of the time- frequency-domain representation of the same frequency band. The water mark signal provider further comprises a time-domain waveform combiner, to combine the provided time-domain waveforms for the plurality of frequencies of the time-frequency-domain provider to derive the watermark signal. |
