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* fp ) 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.

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 np ) 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 watermarked 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 protecting by watermarking against non-authorised use, e.g. non-authorised recording or copying, original audio or video data which are to be presented in a digital cinema, a sender site generates from the original signal at least two differently pre-watermarked versions for successive blocks or frames of the signal, wherein these versions are derived by applying a repeated watermark symbol value to a version and different watermark symbol values to the different versions. The pre-watermarked signal versions are encrypted and transferred e.g. as data files to a digital cinema unit in which they are decrypted. According to the values of a desired watermark information word, corresponding frames or blocks from said decrypted and pre-watermarked versions are assembled in a successive manner, so as to provide and present a watermarked version of said original audio or video signal that carries said watermark information word.

摘要： For determining in a 2nd screen whether or not watermarked audio content received from a 1st screen has been stopped, a watermark symbol detection in the received audio content and a related detection strength value determination is carried out. In case no watermark symbol has been detected, a received expected detection strength value is compared with a detection strength threshold value. If the expected detection strength value is greater than the detection strength threshold value, it is decided that content has been stopped in the 1st screen device. If not,it is decided that content has not been stopped in the 1st screen device. In case a watermark symbol has been detected,the detection strength value is compared with the expected detection strength value,a correspondingly updated detection strength threshold value is calculated, and it is decided that the content has not been stopped in the 1st screen device.

摘要： Improvement of watermark detection in watermarked microphone audio signals picked up in the presence of surrounding noise is achieved by using at encoder side not only the originally received signal for the calculation of the masking threshold and the watermarking strength, but by also taking into account the level of the surrounding noise. This enables an adaptation of the watermarking strength to the current sound pressure level SPL of the surrounding noise. If the SPL of the surrounding noise is increased, the watermarking strength will be increased accordingly. The resulting advantage is a significantly improved audio watermark detection in the presence of surrounding noise.

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： As a potential format for next-generation audio, techniques for embedding digital watermarks in the Higher Order Ambisonics (HOA) representation of a sound field have been proposed. The inventive embedding method is adapted for watermarking a two-dimensional or three-dimensional Ambisonics representation of a sound field, wherein the Ambisonics representation is decomposed into directional signals and ambient components and includes estimated dominant directions, and wherein the order of the ambient components can be reduced, and wherein watermark information data are embedded in the directional signals, and at receiver side are regained from the watermarked directional signals.

摘要： Various audio signal watermarking systems are known, which are also applied to digitally encoded audio signals. However, in current audio signal watermarking systems the watermark signal and its watermark payload do not survive very low bit rate audio coding, in particular parametric coding. According to the invention, a watermarked uncompressed audio signal bitstream is low-bit rate compressed, but the water- marking is removed and the watermark's payload only is transmitted together with the compressed audio signal bit- stream. At decoder side, the received audio signal bit stream is de-compressed and watermarked again using the transmitted watermark payload. Advantageously, it does not matter that the compressed bitstream is not watermarked because the compressed bitstream can be encrypted prior to transmission.
摘要翻译：各种音频信号水印系统是已知的，其也被应用于数字编码的音频信号。然而，在当前音频信号水印系统中，水印信号及其水印有效载荷不能承受非常低的比特率音频编码，特别是参数编码。根据本发明，水印的未压缩音频信号比特流是低比特率压缩的，但水印被去除，水印的有效载荷仅与压缩音频信号比特流一起传输。在解码器侧，使用发送的水印有效载荷对接收到的音频信号比特流进行解压缩和加水印。有利地，由于压缩比特流可以在传输之前被加密，因此压缩的比特流不加水印并不重要。
