Abstract

A system and method for providing content in a digital broadcasting system are provided. The system includes a server for, after a lapse of a buffering time of a segment of the content, storing the segment, and for transmitting an updated Multimedia Presentation Description (MPD) including Uniform Resource Location (URL) information indicating a location where the segment is stored, and a client device for receiving the updated MPD, and for acquiring the segment stored in the location indicated by the URL information included in the updated MPD.

Claims

1. A system for providing content in a digital broadcasting system, the system comprising:

a server for, after a lapse of a buffering time of a segment of the content, storing the segment, and for transmitting an updated Multimedia Presentation Description (MPD) including Uniform Resource Location (URL) information indicating a location where the segment is stored; and

a client device for receiving the updated MPD, and for acquiring the segment stored in the location indicated by the URL information included in the updated MPD.

2. The system of claim 1, wherein the MPD includes information about a time in which the segment was actually broadcasted.

3. The system of claim 1, wherein the MPD is updated in at least one of units of the segment and units of a program formed by the segment.

4. The system of claim 1, wherein the client device requests the server to transmit the updated MPD at a time when the MPD is updated.

5. A method for providing content by a server in a digital broadcasting system, the method comprising:

after a lapse of a buffering time of a segment of the content, storing the segment; and

transmitting, to a client device, an updated Multimedia Presentation Description (MPD) including Uniform Resource Location (URL) information indicating a location where the segment is stored.

6. The method of claim 5, wherein the MPD includes information about a time in which the segment was actually broadcasted.

7. The method of claim 5, wherein the MPD is updated in at least one of units of the segment and units of a program formed by the segment.

8. The method of claim 5, wherein the updated MPD is transmitted at a time when the MPD is updated, after a request for the updated MPD is received from the client device.

9. A server device for providing content for digital broadcast, wherein the server device, after a lapse of a buffering time of a segment of the content, stores the segment, and transmits, to a client device, an updated Multimedia Presentation Description (MPD) including Uniform Resource Location (URL) information indicating a location where the segment is stored.

10. The server device of claim 9, wherein the MPD includes information about a time in which the segment was actually broadcasted.

11. The server device of claim 9, wherein the MPD is updated in at least one of units of the segment and units of a program formed by the segment.

12. The server device of claim 9, wherein the updated MPD is transmitted at a time when the MPD is updated, after a request for the updated MPD is received from the client device.

13. A method for acquiring content by a client device in a digital broadcasting system, the method comprising:

after a lapse of a buffering time of a segment of the content, receiving an updated Multimedia Presentation Description (MPD) including Uniform Resource Location (URL) information of a server where the segment is stored; and

acquiring the segment stored in the location indicated by the URL information included in the updated MPD.

14. The method of claim 13, wherein the MPD includes information about a time in which the segment was actually broadcasted.

15. The method of claim 13, wherein the MPD is updated in at least one of units of the segment and units of a program formed by the segment.

16. The method of claim 13, further comprising requesting the server to transmit the updated MPD at a time when the MPD is updated.

17. A client device for receiving digital broadcast content, wherein the client device, after a lapse of a buffering time of a segment of the content, receives an updated Multimedia Presentation Description (MPD) including Uniform Resource Location (URL) information of a server where the segment is stored, and acquires the segment stored in the location indicated by the URL information included in the updated MPD.

18. The client device of claim 17, wherein the MPD includes information about a time in which the segment was actually broadcasted.

19. The client device of claim 17, wherein the MPD is updated in at least one of units of the segment and units of a program formed by the segment.

20. The client device of claim 17, wherein the client device requests the server to transmit the updated MPD at a time when the MPD is updated.

21. A server device for providing content for digital broadcast, the device comprising:

a storage means for storing a segment of the content, after a lapse of a buffering time of the segment of the content; and

a transmission means for transmitting, to a client device, an updated Multimedia Presentation Description (MPD) including Uniform Resource Location (URL) information indicating a location where the segment is stored in the storage means.

22. The device of claim 21, wherein the MPD includes information about a time in which the segment was actually broadcasted.

23. The device of claim 21, wherein the MPD is updated in units of the segment, or in units of a program formed by the segment.

24. The device of claim 21, wherein the updated MPD is transmitted at a time when the MPD is updated, after a request for the updated MPD is received from the client device.

25. A client device for receiving content for digital broadcast, the device comprising:

a reception means for, after a lapse of a buffering time of a segment of the content, receiving an updated Multimedia Presentation Description (MPD) including Uniform Resource Location (URL) information of a server where the segment is stored; and

an acquisition means for acquiring the segment stored in the location indicated by the URL information included in the updated MPD.

26. The client of claim 25, wherein the MPD includes information about a time in which the segment was actually broadcasted.

27. The client of claim 25, wherein the MPD is updated in at least one of units of the segment and units of a program formed by the segment.

28. The device of claim 25, wherein the device requests the server to transmit the updated MPD at a time when the MPD is updated.
