    摘要： To provide a transmission method of an arbitrary signal using an acoustic sound hardly affecting the mood (quality) of the original acoustic sound even if an arbitrary signal within an audible frequency range is combined into the acoustic sound such as music.The method comprises a step of finding a separable sound, of which a fundamental element (fundamental sound) b2 contributing mainly to recognition of a single sound and an additional element contributing collaterally to recognition of the single sound are separable on temporal axis or frequency axis, among plural sounds composing the acoustic sound, or inserting a separable sound into the plural sounds composing the acoustic sound. The additional element of the separable sound found or inserted is transcribed by a signal pattern b1-1, b1-2 of the arbitrary signal. By means of the acoustic sound of which additional element is transcribed, the arbitrary signal b1-1, b1-2 is transmitted. The additional element may be a sound generated when transmitting vibration energy to a resonance body (resonant body). The fundamental element may be a sound produced according the own resonance mode (resonant mode) by the resonance body (resonant body) receiving the vibration energy.

    摘要： Methods and apparatus to generate and use content-aware watermarks are disclosed herein. An example disclosed method includes detecting a watermark in a first media composition, the watermark encoded with a word present in an audio track of the first media composition, the word audible during playback of the audio track. The example method also includes retrieving the word from the watermark. The example method also includes determining whether the word retrieved from the watermark matches a keyword, and presenting a second media composition when the word matches the keyword.
