Abstract

A method and device for sharing content are provided. The method includes dividing a playback section of the content into a plurality of sections, encoding data in a first section from among the plurality of sections, transmitting the encoded data in the first section to the display device via a first network channel, and transmitting data in a second section, from among the plurality of sections, to the display device via a second network channel while transmitting the encoded data in the first section to the display device.

Claims

1. A method of using a device to share content with a display device, the method comprising:

dividing a playback section of the content into a plurality of sections;

encoding data in a first section from among the plurality of sections;

transmitting the encoded data in the first section to the display device via a first network channel; and

transmitting data in a second section, from among the plurality of sections, to the display device via a second network channel while transmitting the encoded data in the first section to the display device.

2. The method of claim 1, wherein the dividing of the playback section of the content comprises determining a segment section between the first section and the second section in consideration of at least one of a bit rate of the content, a playback length of the content, and a bandwidth of the second network channel.

3. The method of claim 1, further comprising measuring at least one of a bandwidth of the first network channel and a bandwidth of the second network channel.

4. The method of claim 1, wherein the dividing of the playback section of the content comprises:

changing a playback position of the content based on a user input; and

dividing a playback section that extends from the changed playback position to a last playback position into a plurality of sections.

5. The method of claim 1, wherein the dividing of the playback section of the content comprises:

comparing a bandwidth of the second network channel and a bit rate of the content; and

selectively dividing the playback section of the content based on a comparison result.

6. The method of claim 5, wherein the dividing of the playback section of the content comprises dividing the playback section of the content into a plurality of sections when the bandwidth of the second network channel is less than the bit rate of the content based on the comparison result.

7. The method of claim 1, wherein the first network channel and the second network channel each comprise a short-range communication channel.

8. The method of claim 1, wherein the first network channel comprises a Wireless-Fidelity (Wi-Fi) communication channel;

and

the second network channel comprises a Wi-Fi Direct (WFD) communication channel.

9. The method of claim 1, further comprising transmitting data in a third section, from among the plurality of sections, to the display device via the first network channel while the data in the second section are played in the display device.

10. The method of claim 9, wherein the dividing of the playback section of the content comprises determining at least one segment point between the first section, the second section, and third section in consideration of at least one of a bit rate of the content, a playback length of the content, a bandwidth of the first network channel, and a bandwidth of the second network channel.

11. The method of claim 9, wherein the data in the second section and the data in the third section, which are transmitted to the display device, are uncompressed original data.

12. A non-transitory computer readable recording medium having a program recorded thereon, which, when executed by a computer, implements the method of claim 1.

13. A device to share content with a display device, the device comprising:

a control unit configured to divide a playback section of content into a plurality of sections;

an encoding unit configured to encode data in a first section from among the plurality of sections;

a first communication unit configured to transmit the encoded data in the first section to a display device via a first network channel; and

a second communication unit configured to transmit data in a second section, from among the plurality of sections, to the display device via a second network channel while the encoded data in the first section are transmitted to the display device.

14. The device of claim 13, wherein the control unit determines a segment section between the first section and the second section in consideration of at least one of a bit rate of the content, a playback length of the content, and a bandwidth of the second network channel.

15. The device of claim 13, further comprising a network measurement unit measuring at least one of a bandwidth of the first network channel and a bandwidth of the second network channel.

16. The device of claim 13, wherein the control unit changes a playback position of the content based on a user input and divides a playback section extending from the changed playback position to a last playback position into a plurality of sections.

17. The device of claim 13, wherein the control unit compares a bandwidth of the second network channel and a bit rate of the content and selectively divides the playback section of the content into a plurality of sections based on a comparison result.

18. The device of claim 17, wherein the control unit divides the playback section of the content into the plurality of sections, based on the comparison result, when the bandwidth of the second network channel is less than the bit rate of the content.

19. The device of claim 13, wherein the first communication unit transmits data in a third section, from among the plurality of sections, to the display device via the first network channel while the data in the second section are played in the display device.

20. The device of claim 19, wherein the control unit determines segment points between the first section, the second section, and third section in consideration of at least one of a bit rate of the content, a playback length of the content, a bandwidth of the first network channel, and a bandwidth of the second network channel.
