摘要： A watermark signal provider provides a watermark signal suitable for being hidden in an audio signal when the watermark signal is added to the audio signal, such that the watermark signal represents watermark data. The watermark signal provider includes a psychoacoustical processor for determining a masking threshold of the audio signal; and a modulator for generating the watermark signal from a superposition of sample-shaping functions spaced apart from each other at a sample time interval of a time-discrete representation of the watermark data, each sample-shaping function being amplitude-weighted with a respective sample of the time-discrete representation, multiplied by a respective amplitude weight depending on the masking threshold, the modulator being configured such that the sample time interval is shorter than a time extension of the sample-shaping functions; and the respective amplitude weight also depends on samples of the time-discrete representation neighboring the respective sample in time.

摘要： A watermark decoder includes a time-frequency-domain representation provider, a memory unit, a synchronization determiner and a watermark extractor. The time-frequency-domain representation provider provides a frequency-domain representation of the watermarked signal for a plurality of time blocks. The memory unit stores the frequency-domain representation of the watermarked signal for a plurality of time blocks. Further, the synchronization determiner identifies an alignment time block based on the frequency-domain representation of the watermarked signal of a plurality of time blocks. The watermark extractor provides binary message data based on stored frequency-domain representations of the watermarked signal of time blocks temporally preceding the identified alignment time block considering a distance to the identified alignment time block.

The time-frequency-domain waveform provider is configured to map a given value of a time-frequency-domain representation onto a bit shaping function, a temporal extension of which is longer than a bit interval, 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. The water mark signal provider further has a time-domain waveform combiner.

摘要： The inventive concept enables backward-compatible extension of existing interleaver-based transmission systems to the effect that in addition to an existing logical transport channel, which is interleaved using a standardized interleaver profile, further logical transport channels may be transmitted via the same physical transmission channel. In this context, the first transport channel obviously is reduced in terms of data rate, so that the additional transport channels may actually obtain a transmission capacity that is needed accordingly. Interleaver profiles of the further logical transport channels are derived, to this end, from the interleaver profile of the first transport channel.
摘要翻译：本发明的概念使得现有基于交织器的传输系统能够向后兼容扩展，除了使用标准交织器简档交织的现有逻辑传输信道之外，还可以经由相同的物理传输信道。在这种情况下，第一传输信道在数据速率方面明显地被减少，使得附加的传输信道实际上可以获得相应的传输容量。为此，从第一传输信道的交织器简档导出进一步的逻辑传输信道的交织器简档。
