Abstract

Disclosed are a device and a method for outputting a sound wave for content synchronization between devices and operation control of an external device, and the external device. The device for outputting a sound wave according to one embodiment of the present invention includes: a storage unit configured to store content data of content; a playing unit configured to play the content data; and an output unit configured to output a sound wave as a result of the playing of the content data, wherein the sound wave allows an external device to initiate an operation associated with the content.

Claims

1. A device for outputting a sound wave, comprising:

a storage unit configured to store content data of content;

a playing unit configured to play the content data; and

an output unit configured to output a sound wave as a result of the playing of the content data,

wherein the sound wave allows an external device to initiate an operation associated with the content.

2. The device of claim 1, wherein the content data includes video data corresponding to the content, audio data corresponding the content, and sound wave data corresponding to control information,

wherein the sound wave includes a first sound wave component corresponding to the audio data and a second sound wave component corresponding to the sound wave data.

3. The device of claim 2, wherein the first sound wave component has a frequency selected within a range of 100 Hz to 16000 Hz, and the second sound wave component has a frequency selected within a range of 16000 Hz to 24000 Hz.

4. The device of claim 1, wherein the content is an e-book content or an audio book content, and the operation displays an image corresponding to the e-book content or the audio book content on a display of the external device.

5. The device of claim 1, further comprising:

a control information generation unit configured to generate the control information associated with the content; and

a sound wave data generation unit configured to generate sound wave data corresponding to the control information,

wherein the playing unit plays the generated sound wave data and the content data.

6. The device of claim 1, further comprising:

a control information generation unit configured to generate control information associated with the content;

a sound wave data generation unit configured to generate sound wave data corresponding to the control information; and

a data update unit configured to synthesize the audio data and the sound wave data that are included in the content data to update the content data,

wherein the playing unit plays the updated content data.

7. The device of claim 5, wherein the output unit outputs a first sound wave corresponding to the content data played through a sound wave output device, and outputs a second sound wave corresponding to the sound wave data played through the sound wave output device.

8. The device of claim 1, wherein the device is a mobile device, and the content is a music content,

when a call or a message is input to the mobile device, the playing unit plays the music content, and

the external device initiates an operation of informing that the call or the message is input.

9. The device of claim 1, further comprising:

a display unit configured to display an image or a text on the display of the device as a result of the playing of the content data,

wherein the operation displays the image or the text on the display of the external device.

10. The device of claim 5, wherein the device is a mobile device, the external device is a navigation device, and the content is a road guide application,

the control information includes geographical coordinates corresponding to a search word input from a user interface, and

the operation displays the search word on the display of the external device.

11. The device of claim 5, wherein the device is a mobile device, the external device is an external mobile device, and the content is a moving picture content,

the control information includes synchronization information or time information corresponding to the moving picture content, and

the operation is an operation corresponding to the synchronization information or the time information of the external device.

12. The device of claim 5, wherein the control information generation unit generates first control information and second control information,

the sound wave data generation unit generates first sound wave data corresponding to the first control information and second sound wave data corresponding to the second control information,

the playing unit plays the first sound wave data, the second sound wave data, and the content data,

the output unit outputs a first sound wave and a second sound wave, and

the first sound wave allows a first external device to initiate a first operation associated with the content, and the second sound wave allows a second external device to initiate a second operation associated with the content.

13. The device of claim 1, wherein the sound wave includes a first sound wave component and a second sound wave component,

the first sound wave component allows a first external device to initiate a first operation associated with the content, and the second sound wave component allows a second external device to initiate a second operation associated with the content.

14. A method for outputting a sound wave, comprising:

storing content data of content;

playing the content data; and

outputting a sound wave as a result of the playing of the content data,

wherein the sound wave allows an external device to initiate an operation associated with the content.

15. The method of claim 14, further comprising:

generating control information associated with the content; and

generating sound wave data corresponding to the control information,

wherein in the playing of the content data, the content data and the sound wave data are played.

16. A device for performing an operation corresponding to a sound wave, comprising:

a sound wave input unit configured to receive a sound wave output from an external device;

a control information acquisition unit configured to acquire control information using the received sound wave; and

an operation performance unit configured to perform an operation based on the control information,

wherein the operation is associated with a content that is being played by the external device.
