摘要： In watermark symbol detection for watermarked audio signals a correlation and statistical detection is used, which is computationally complex. Therefore a downsampling can be used prior to the correlation. However, if the watermarked audio signals are transmitted over an acoustic path, without downsampling the detection rate is considerably higher than the detection rate when including downsampling of the correlation input signals. There is a trade-off between calculation complexity and detection robustness. According to the invention, an interpolation of the correlation result values is carried out for input to the statistical detector, in order to approximate the detection robustness of correlation without downsampling.

摘要： Following transmission of a watermarked audio signal over an acoustic path causing echoes, reverberation and/or noise, watermark detection correlation result peak values are concentrated within a limited temporal range around main correlation result peaks, which limited temporal range is much smaller than the total correlation length. The watermark detection is based on the following: given n p correlation result peak values v =( v 1 , v 2 , ..., v n p ) in an average or expected probability distribution for correlation result values for unmarked content, the probability is calculated that within windows covering the limited temporal range there are n p or more values from a correlation result value set greater than or equal to these peaks v .

摘要： Many watermarking detection algorithms are correlation based, whereby an input signal is correlated with reference signals. The correlation with the best match determines the bit value of the watermark information. Usually a water-marked signal undergoes distortion before being fed to a watermark detector. However, the modification is stronger in some frequency ranges than in others. According to the invention, the correlation result for a current input signal section is in addition used for estimating the optimal frequency range or ranges for the following section's correlation, using a cumulative correlation value curve.

摘要： For determining the audience figures of a TV or radio program, audio watermarking can be used. Panelists are carrying a mobile receiver including a microphone (MIC), whereby the received acoustic signal is checked (WMD) for watermark data. Because movement of the mobile receiver causes a Doppler shift in the received acoustic signal (AWMS), for detecting an embedded watermark a frequency search (FRS) within a given frequency range must be carried out. According to the invention, the current maximum motion speed of the mobile receiver is determined (GSR, ACC, MSPC) and is used for decreasing the frequency range within which the correct frequency needs to be searched.

摘要： Watermark symbol detection requires a detection metric for deciding at decoder side which candidate symbol is embedded inside the audio or video signal content. The invention provides an improved detection metric processing that achieves a reliable detection of watermarks in the presence of additional noise and echoes, and that is adaptive to signal reception conditions and requires a decreased computational power. This is performed by taking into account the information contained in the echoes of the received audio signal in the decision metric and comparing it with the corresponding metric obtained from decoding a non-marked audio signal, based on recursive calculation of false positive detection rates of peaks in correlation result values. The watermark symbol corresponding to the reference sequence having the lowest false positive error is selected as the embedded one.

摘要： In audio processing technology there are interfaces of different type, the different interface types being associated with differing sample clock frequencies and/or differing data frame or data word formats. In some applications it is desired do process audio signals that stem from such interfaces of different type. According to the invention the input signals of the interfaces of different type are preprocessed for a subsequent common-format central processing, using a synchronisation to the common system clock, channel decoding according to the differing channel protocols related to the different-type interfaces, and processing the resulting PCM bitstream format signals so as to form therefrom sample words that are stored in an intermediate store from which the sample words are fed to the central processing.

摘要： Manufacturers of audio processing software plug-ins are losing revenues due to the illegal use of their software. Because unauthorised copying of software cannot be prevented, the question is how to find transgressors and how to prove non-licensed use of such plug-ins. The invention facilitates determining whether non-licensed audio processing software has been used, even without physical access the computer using that software. The original audio processing software includes a watermarking embedder for embedding a watermark in the software-processed audio data stream, in order to identify the audio effects software. The software-processed audio data is always watermarked with an identification string related to the special audio effect software applied.

摘要： From sets of correlation result values it is determined whether a specific watermark symbol out of one or more candidate watermark symbols is embedded in a received audio signal. For all candidate watermark symbols, from each corresponding set of correlation result values, a group ( n p ) of maximal values together form a peak vector ( v i ). From the normalised peak values (w i ) a probability distribution function (pdf, g (w i )) and a false positive probability function ( P fp (w i )) are calculated. If the values of the false positive probability function are smaller than a first threshold value (T min ), the current candidate watermark symbol is taken as a true watermark symbol. If not yet all candidate watermark symbols have been processed, the next candidate watermark symbol is selected. Otherwise, a minimal value P f p * of the false positive probability functions for all candidate watermark symbols is determined (76) and is compared (77) with a second threshold value (T max ). If it is smaller than the second threshold value, the current candidate watermark symbol is selected. Otherwise, it is determined (78) that no watermark symbol is present.
