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： 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： Audio watermarking is the process of embedding watermark information items into an audio signal in an in-audible manner. In a first embodiment, in case the original audio signal has parts of low signal energy, an alternative signal having a level or strength given by the psycho-acoustic model is combined with the original audio signal. The combined signal is watermarked with watermark data to be embedded. In a second embodiment, in case the original audio signal has parts of low signal energy, an alternative signal having a level or strength given by the psycho-acoustic model is watermarked with watermark data to be embedded, and the audio signal is watermarked with the watermark data to be embedded. The watermarked alternative signal is combined with the watermarked audio signal.

摘要： For synchronizing at least two devices to playback with regard to a user position the same audio or audio and video content synchronously without to setup each device separately and to launch a reproduction of the content reproduced by a first reproduction device also with a second reproduction device, the use of audio watermarks in audio or audio and video content provided by a media server and a mobile device as e.g. a smartphone, iPhone or phablet to perform the tasks are recommended. A synchronised reproduction of the same audio or audio and video content reproduced by the at least two reproduction devices is performed upon initialisation or a switched on status of the mobile device without a further user request if both reproduction devices reproduce the same content. The recommended system is preferred applicable in a multi room environment with reproduction devices where the content is provided by a media server.

摘要： A method for synchronizing display of information on a second screen device (8) with display of audiovisual data on a main screen device (7) is described. The second screen device (8) detects (20) an occurrence of one of a plurality of predefined identifiers embedded in the audiovisual data displayed on the main screen device (7) and retrieves (22) information to be displayed associated to the detected identifier. The retrieved information is then displayed (23) on the second screen device (8). The audiovisual data is prepared for transmission by detecting (11) an occurrence of one of a plurality of predefined situations in the audiovisual data and inserting (13) an identifier associated to the detected predefined situation in the audiovisual data at or close to the point in time of occurrence of the predefined situation.
