Abstract

Disclosed are an information storage medium having recorded thereon service information regarding a broadcast service to provide additional content, the information storage medium having recorded thereon information for receiving a trigger while the broadcast service is received, information for selecting additional content to be inserted to the broadcast service in correspondence to the received trigger, and a locator for receiving the additional content, a method of providing additional content by using the same, and a digital broadcast reception apparatus.

Claims

1. An information storage medium having recorded thereon service information regarding a broadcast service to cause a computer to provide additional content, the information storage medium having recorded thereon:

information for receiving a trigger while the broadcast service is received;

information for selecting additional content to be inserted to the broadcast service in correspondence to the received trigger; and

a locator for receiving the additional content.

2. The information storage medium of claim 1, wherein the information for receiving the trigger comprises a locator of a server transmitting the trigger.

3. The information storage medium of claim 1, wherein the information for selecting the additional content comprises information for identifying insertion of the additional content and information for identifying the additional content.

4. The information storage medium of claim 3, wherein there are a plurality of the information for identifying the additional content and a plurality of locators of the additional content.

5. The information storage medium of claim 1, having further recorded thereon information instructing termination of insertion of additional content based on the received trigger.

6. A method of providing additional content while a broadcast service is received, the method comprising:

receiving, using a receiver, service information regarding the broadcast service;

receiving a trigger;

selecting additional content corresponding to the trigger by using the service information; and

receiving the selected additional content by using a locator included in the service information and reproducing the received additional content.

7. The method of claim 6, wherein the receiving of the trigger comprises receiving the trigger from a server corresponding to a locator of a trigger transmitting server, the locator included in the service information.

8. The method of claim 6, wherein the receiving of the trigger comprises filtering trigger information from a transport stream of the broadcast service.

9. The method of claim 6, wherein the selecting of the additional content comprises searching the service information for additional content information corresponding to information for identifying insertion of additional content and information for identifying additional content, the information included in the trigger.

10. The method of claim 6, further comprising, if additional content information corresponding to the received trigger instructs to terminate insertion of additional content, restoring the broadcast service.

11. The method of claim 6, further comprising, if additional content information corresponding to the received trigger does not exist in the service information, reproducing an underlying additional content included in the broadcast service.

12. A computer readable recording medium having recorded thereon a computer program for causing a computer to execute the method of claim 6.

13. A digital broadcast reception apparatus comprising:

a reception unit which receives broadcast service, service information regarding the broadcast service, a trigger, and additional content;

a playback unit which reproduces data received via the reception unit; and

a control unit which controls the reception unit and the playback unit to select additional content corresponding to the trigger when the trigger is received, to receive the selected additional content by using a locator included in the service information, and to reproduce the received additional content.

14. The digital broadcast reception apparatus of claim 13, wherein the control unit controls the reception unit to receive the trigger from a server corresponding to a locator of a trigger transmitting server, the locator included in the service information.

15. The digital broadcast reception apparatus of claim 13, wherein the control unit controls the reception unit to receive the trigger by filtering trigger information from a transport stream of the broadcast service.

16. The digital broadcast reception apparatus of claim 13, wherein the control unit searches for additional content information corresponding to information for identifying insertion of additional content and information for identifying additional content, the information included in the trigger, in the service information.

17. The digital broadcast reception apparatus of claim 13, wherein, if additional content information corresponding to the received trigger instructs to terminate insertion of additional content, the control unit controls the reception unit and the playback unit to restore the broadcast service.

18. The digital broadcast reception apparatus of claim 13, wherein, if additional content information corresponding to the received trigger does not exist in the service information, the control unit controls the reception unit and the playback unit to reproduce an underlying additional content included in the broadcast service.
