Abstract

A content processing apparatus using sound includes a sound processor configured to generate acoustic sound for a locality check when an event in which locality check is to be executed is generated, a speaker configured to output the acoustic sound, a microphone configured to receive response sound output from an external apparatus which receives the acoustic sound, and a controller configured to determine the external apparatus which outputs the response sound as a peripheral apparatus.

Claims

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.

2. The content processing apparatus as claimed in claim 1, wherein the basic sound comprises music sound or sound of an inaudible frequency band.

3. The content processing apparatus as claimed in claim 2, further comprising an input unit configured to receive the content sharing command,

wherein the controller determines that the event is generated when the content sharing command is received and controls the sound processor and the speaker to output the acoustic sound.

4. The content processing apparatus as claimed in claim 3, wherein the controller communicates with the peripheral apparatus to transmit or receive content when the number of peripheral apparatuses is determined to be one.

5. The content processing apparatus as claimed in claim 3, further comprising a display unit configured to display a list for a plurality of peripheral apparatuses,

wherein, when one peripheral apparatus is selected in the list, the controller communicates with the selected peripheral apparatus to transmit or receive content.

6. The content processing apparatus as claimed in claim 1, wherein, when output acoustic sound from other apparatuses is received through the microphone, the controller detects data for the locality check mixed with the received acoustic sound and controls the sound processor and the speaker to output response sound to the other apparatuses using the detected data.

7. A content processing method using sound, comprising:

generating acoustic sound for locality check when an event in which locality check is to be executed is generated by mixing data for the locality check with preset basic sound to generate the acoustic sound when a content sharing command is received;

outputting the acoustic sound from a content processing apparatus;

receiving output response sound from an external apparatus which receives the acoustic sound;

determining the external apparatus which outputs the response sound as a peripheral apparatus;

storing the data for the locality check;

dividing the preset basic sound into a high band and low band;

encoding the data with forward error correction;

modulating both the high band and the encoded data using orthogonal frequency division multiplex (OFDM) modulation to obtain an OFDM modulated signal;

adding the low band to the OFDM modulated signal.

8. The content processing method as claimed in claim 7, wherein the basic sound comprises music sound or sound of an inaudible frequency band.

9. The content processing method as claimed in claim 8, further comprising:

receiving the content sharing command; and

determining that the event is generated when the content sharing command is received.

10. The content processing method as claimed in claim 9, further comprising communicating with the peripheral apparatus to transmit or receive content when the number of peripheral apparatuses is determined to be one.

11. The content processing method as claimed in claim 9, further comprising:

displaying a list for a plurality of peripheral apparatuses; and

communicating with a selected peripheral apparatus to transmit or receive content when one peripheral apparatus is selected in the list.

12. The content processing method as claimed in claim 7, further comprising, when output acoustic sound from other apparatuses is received, detecting data for the locality check mixed with the received acoustic sound and outputting response sound to the other apparatuses using the detected data.

13. A non-transitory computer-readable recording medium storing a program to implement the method of claim 7.

14. A content processing system using sound, the system comprising:

a transmission-side content processing apparatus comprising;

a first sound processor configured to generate a locality check sound signal by mixing data for a locality check with preset basic sound to generate the acoustic sound when a content sharing command is received;

a first speaker configured to output the generated locality check sound signal;

a first microphone configured to receive an output response sound signal;

a first controller;

a storage configured to store the data for the locality check;

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; and

a reception-side content processing apparatus comprising;

a second microphone configured to receive the locality check sound signal;

a second controller configured to confirm the locality check sound signal;

a second sound processor configured to generate the output response sound signal; and

a second speaker configured to output the generated output response sound signal,

wherein the first controller is configured to identify the reception-side content processing apparatus based on the output response sound signal.

15. The system of claim 14, wherein the locality check sound signal and the output response sound are generated to be imperceptible to a user of the content processing system.
