<p>PURPOSE: An information transmission/reception system and a method thereof in sound wave communication are provided to transfer additional data based on audio content to a personal sound device. CONSTITUTION: A transmission unit(100) selects frequency section. The transmission unit generates a modulated audio signal. The transmission unit outputs an audio signal which is formed through reverse conversion related to the modulated audio signal. A reception unit(200) receives the output audio signal. The reception unit extracts the information data from the output audio signal.</p> |
