    Abstract: An apparatus and a method for embedding ad extracting a capturing-resistant wavelet-based audio watermark and a copyright management system using the apparatus and the method are provided to discrete-wavelet-transform an audio signal and embed a watermark in the audio signal such that the watermark is robust against lossy compression. An apparatus for embedding a wavelet-base audio watermark includes a framing unit(110), a discrete wavelet transformer(130), and an embedding unit(140). The framing unit divides an input audio signal into small signals having a predetermined length. The discrete wavelet transformer discrete-wavelet-transforms the small signals to calculate an average value of wavelet coefficients. The embedding unit varies the average value of the discrete wavelet coefficients according to a watermark to be embedded and embeds the watermark in the audio signal.

    Abstract: PURPOSE: A unit for detecting a watermark is provided to realize firmness regarding a collusion attack, by not increasing a code length of a built-in code as watermark information even if the whole number of users and colluders are large. CONSTITUTION: One code word selected from a plurality of code words forming a single code is outputted in response to an inputted user identification number. A correlation value is obtained between the outputted code word and a content. Whether a code word corresponding to the inputted user identification number based upon the correlation value is in the content is determined. The unit(2) for detecting a watermark detects watermark information including the information of the user identification number from a predetermined content.

    Abstract: The present disclosure describes an efficient computer-implemented near-field communication system and method based on broadcasting audio signals for dynamically providing context-related additional content to a mobile device. In embodiments of the present invention, the additional content is mapped to specific audio watermarks and/or triggering commands which are encoded together into a digital signal. Based on continuously scanning the received background noise, an exactly defined frequency range and volume is dynamically selected for broadcasting the signal. Hence, the encoded digital signal is further modulated into an audio signal in the exactly defined frequency range. In embodiments of the present invention, the selected exactly defined frequency range for transmitting the audio signal may preferably be located in the ultrasound and/or infrasound frequency range. In case of transmitting infrasound signals, gyrosensors of the mobile device may be employed as audio signal receivers in embodiments of the present invention. Moreover, in further embodiments of the present invention, audio signal receiver of a mobile device such as gyrosensors or microphones may be switched on by transmitting a command via a wireless network such as Wifi or Bluetooth. Also the information about the selected frequency range and volume for broadcasting the audio signal may be provided to the mobile device via a wireless network in embodiments of the present invention. In response, an audio signal receiver of the mobile device may be tuned to the selected frequency range. The received audio signal is further processed on the mobile device so that the context-related additional content may be displayed and/or rendered.

    Abstract: Methods, apparatus, and articles of manufacture for reducing spillover in a media monitoring system are disclosed. An example method includes identifying media associated with media monitoring data. The media monitoring data is received from a first meter associated with a first media presentation device. The example method includes identifying an expected sound pressure level associated with the first meter. The example method includes comparing the expected sound pressure level to an actual sound pressure level collected from the media by the first meter to determine if spillover occurred. The example method includes crediting the media as a media exposure if spillover did not occur.

    Abstract: Systems and methods are disclosed for synchronizing devices that produce identifiable characteristics from audio media. A device receives audio and produces initial time data. Subsequent time data is received at a coupling interface from a portable device that has access to accurate time sources. The subsequent time data is processed to determine if it is more accurate than the initial time data. If so, the clock of the device is updated to reflect the second time data. The device then processes the audio media to generate at least one identifiable characteristic relating to the audio, which may include ancillary codes and/or audio signatures. The identifiable characteristics are then transmitted together with the subsequent time data for detection.
