摘要： Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to utilize audio watermarking for people monitoring are disclosed. Example people monitoring methods disclosed herein include determining, at a user device, whether a first trigger condition for emitting an audio watermark identifying at least one of the user device or a user of the user device is satisfied. Such example methods also include, in response to determining that the first trigger condition is satisfied, providing a first audio signal including the audio watermark to an audio circuit that is to output an acoustic signal from the user device.

摘要： An encoding method and encoder is provided for transparent lossless audio watermarking by quantising an original PCM audio signal twice, each quantisation quantising to a quantisation grid. As a PCM signal is inherently already quantised, there are three quantisation grids to consider, the first being the quantisation grid of the original PCM signal, the second being that of the watermarked signal and the third being that of an intermediate signal. The technique reduces the amount of introduced quantisation error, spectrally shapes the error and fully decorrelates signal alterations from the original audio, thus making the error more similar to additive noise. A decoding method and decoder is also provided, as is a method of altering the watermark without fully decoding the encoded signal.
摘要翻译：通过量化原始PCM音频信号两次，为透明无损音频水印提供编码方法和编码器，每个量化量化到量化网格。由于PCM信号本质上已被量化，所以需要考虑三个量化网格，首先是原始PCM信号的量化网格，第二个是水印信号的量化网格，第三个是中间信号的量化网格。该技术减少了引入的量化误差的量，频谱地形成误差并完全解相关信号从原始音频变化，从而使误差更加类似于加性噪声。还提供了解码方法和解码器，以及在不完全解码编码信号的情况下改变水印的方法。

摘要： Embodiments of the invention are directed to systems, methods and computer program products for providing targeted location-based communications. An exemplary apparatus is configured to receive an encoded signal, decode the encoded signal such that embedded data is retrieved, send the embedded data a remote server; and receive a message based at least partially on sending the embedded data. Another exemplary apparatus is configured to provide the encoded signal by receiving data input, receiving a host signal, embedding the data input within the host signal such that an encoded signal is generated, and transmitting the encoded signal. A third exemplary apparatus is configured to provide the targeted communications by storing one or more messages associated with an entity, receiving data, selecting at least one of the one or more messages based at least partially on the data received, and sending the at least one of the one or more messages selected.

摘要： The invention relates to a method of increasing the sensitivity of a watermark detector. The method concerns the extraction of a watermark composed by the repeating of the elementary components of the load to be transmitted in a coverage channel. The method comprises: - a step of extracting repeated elementary components; then - a step of evaluating the individual quality (for example the reliability) of each repetition of each elementary component; - a step of selecting the individualities forming the repetition of each elementary component; - a step of merging the winners of the previous selection so as to determine the value of each elementary component constituting the watermark information with the coverage signal.

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 .
