    Abstract: A user (102) hears an audio program being broadcast and can record a sample of the audio. The sample is then conveyed to an analyzing means (106) to determine to which broadcast station the user is listening. The analyzing means monitors many broadcast channels. Thus, characteristics of the audio sample and samples taken from the broadcast channels can be compared to find a match. Broadcast information pertaining to the broadcast channel from which the match was found may then be reported back to the user, combined with an advertisement of a promotion, prize notification, discount offers, and other information specific for a certain radio station for example.

    Abstract: The acoustic signal transmission method is based on generating a synthesized sound electrical signal by electrically synthesizing an audible sound signal and another signal different than the audible sound signal at the sending side, and transmitting the synthesized sound electrical signal, and extracting the another signal different than the audible sound signal from the synthesized sound electrical signal at the receiving side. Here, generation of the synthesized sound electrical signal is made by using a data hiding technique, for example. Accordingly, the acoustic signal represented by the synthesized sound electrical signal can be heard by human ears in the same way as the audible sound signal, and the synthesized another signal cannot be detected by human ears. Here, the synthesized sound electrical signal can be transmitted as a sound wave in air space, as electrical signal through a transmission line or as radio signals such as infrared and electromagnetic waves.

    Abstract: Spread spectrum technology is used for watermarking digital audio signals. To retrieve a watermark signal information bit from the spread spectrum at the receiver or decoder side, the received or replayed spectrum is convolved with a spreading function that is time-inverse with respect to the original spreading function. The pseudo noise sequences are modulated on carrier frequencies which are inserted at one or more frequency bands into the spectrum of an audio signal. The watermark signal decoder checks the frequency bands occupied by such carriers. The frequency band occupation information is signaled in advance, i.e. is transmitted already together with the frame data for the current frame, such that the watermark signal decoder knows before processing the following audio signal frame which carrier frequencies are occupied and must be used for the corresponding carrier demodulation, and which carrier frequencies need not be checked and demodulated.

    Abstract: A first video characteristic value is determined from a video/audio signal. The first video characteristic value is embedded in an audio portion of the video/audio signal and the video/audio signal is transmitted from a transmission source to a transmission destination. At the destination, the first video characteristic value is recovered and the received video/audio signal is used to determine a second video characteristic value. The recovered first video characteristic value is used to verify or check the second video characteristic value. By comparing the first and second video characteristic values, a determination is made about degradation of the received video/audio signal. In one example, a determination is made as to whether a lip-sync error has likely occurred. In another example, the audio-transmitted first video characteristic is used for copyright protection purposes.

    Abstract translation: 从视频/音频信号确定第一视频特征值。 第一视频特征值嵌入在视频/音频信号的音频部分中，​​并且视频/音频信号从发送源发送到发送目的地。 在目的地，恢复第一视频特征值，并且使用所接收的视频/音频信号来确定第二视频特征值。 恢复的第一视频特征值用于验证或检查第二视频特征值。 通过比较第一和第二视频特征值，确定接收到的视频/音频信号的劣化。 在一个示例中，确定是否可能发生唇同步误差。 在另一示例中，音频发送的第一视频特性用于版权保护目的。
