Claim Text:
1. A content processing apparatus using sound, comprising: a sound processor configured to generate acoustic sound for a locality check when an event in which a locality check is to be executed is generated; a speaker configured to output the acoustic sound; a microphone configured to receive an output response sound from an external apparatus which receives the acoustic sound; a controller configured to determine the external apparatus which outputs the response sound as a peripheral apparatus; and a storage unit in which data for the locality check is stored; wherein the sound processor mixes the data with preset basic sound to generate the acoustic sound when a content sharing command is received; and wherein the sound processor comprises: a band divider to divide the preset basic sound into a high band and a low band; a forward error correction processor to encode the data with forward error correction; an orthogonal frequency division multiplex (OFDM) modulator to modulate both the high band and the encoded data; and a mixer to add the low band to an output from the OFDM modulator.
