SYSTEM AND METHOD FOR DATA RECEPTION AND TRANSMISSION IN AUDIBLE FREQUENCY BAND

摘要

The present invention discloses a system and method for data reception and transmission in an audible frequency band.  The system of the present invention for data reception and transmission in an audible frequency band comprises a data input part for entering data regarding a sound communication target into an audio signal, a transmission part for outputting an audio signal including data to an audible frequency band, and a reception part for receiving an audio signal including data, performing synchronization based on matching filtering, and extracting data according to data extraction processing already set up.  Thus, the present invention enables loading of data regarding a sound communication target onto an audio signal in an audible frequency band and efficient delivery to a receiving side by adding and entering the data onto an audio signal and sending this via an audible frequency band.
