Abstract

Disclosed are an information storage medium storing metadata for providing additional content during a broadcast program, the metadata including information indicating whether to insert second additional content instead of first additional content, which is underlying additional content of the broadcast program, and a locator of the second additional content, a method of providing additional content by using the same, and a digital broadcast reception apparatus.

Claims

1. An information storage medium storing metadata for providing additional content during a broadcast program, the metadata comprising:

information indicating whether to insert second additional content instead of first additional content, which is underlying additional content of the broadcast program; and

a locator of the second additional content.

2. The information storage medium of claim 1, wherein the information indicating whether to insert the second additional content comprises priority information with respect to the first additional content and the second additional content, and instructs the one of the first and second additional contents having the higher priority to be reproduced.

3. The information storage medium of claim 1, the metadata further comprising information regarding time points to reproduce the first additional content or the second additional content.

4. The information storage medium of claim 1, the metadata further comprising a locator of the first additional content.

5. The information storage medium of claim 1, wherein the locator of the second additional content is written in the form of URI (uniform resource identifier).

6. A method of providing additional content, the method comprising:

receiving metadata regarding a broadcast program;

decoding, using a decoder, the metadata and determining whether to insert second additional content instead of first additional content, which is underlying additional content of the broadcast program;

if it is determined to insert the second additional content, obtaining a locator of the second additional content from the metadata; and

receiving the second additional content by using the obtained locator and reproducing the second additional content.

7. The method of claim 6, wherein the determining of whether to insert the second additional content comprises:

comparing priorities of the first additional content and the second additional content, the priorities being included in the metadata; and

determining the one of the first and second additional contents having the higher priority to be reproduced.

8. The method of claim 6, further comprising decoding the metadata and determining a time point to begin reproduction of the first additional content or the second additional content.

9. The method of claim 6, further comprising:

if it is determined to reproduce the first additional content, obtaining a locator of the first additional content from the metadata; and

receiving the first additional content by using the locator and reproducing the first additional content.

10. The method of claim 6, wherein the locator of the second additional content is written in the form of URI (uniform resource identifier).

11. A computer readable recording medium having recorded thereon a program that causes a computer to execute the method of claim 6.

12. A digital broadcast reception apparatus comprising:

a reception unit which receives a broadcast program, metadata regarding the broadcast program, and additional content;

a playback unit which produces data received by the reception unit; and

a control unit which determines whether to insert second additional content instead of first additional content, which is underlying additional content of the broadcast program, and, if it is determined to insert the second additional content, controls the reception unit and the playback unit to receive the second additional content by using a locator thereof included in the metadata and to reproduce the second additional content.

13. The digital broadcast reception apparatus of claim 12, wherein the control unit compares priorities with respect to the first additional content and the second additional content and determines the additional content having the higher priority to be reproduced.

14. The digital broadcast reception apparatus of claim 12, wherein the control unit decodes the metadata and determines a time point to begin reproduction of the first additional content or the second additional content.

15. The digital broadcast reception apparatus of claim 12, wherein, if it is determined to reproduce the first additional content, the control unit controls the reception unit and the playback unit to receive the first additional content by using a locator thereof included in the metadata and to reproduce the first additional content.

16. The digital broadcast reception apparatus of claim 12, wherein the locator of the second additional content is written in the form of URI (uniform resource identifier).
