Abstract

An apparatus and method for receiving and processing a data broadcast signal supported by a data broadcast platform is disclosed. Upon receiving a data broadcast signal including an application information table and an application, the apparatus detects property information indicating a property of the application from the application information table, and controls an additional service of the application on the basis of the detected application property information. Therefore, the apparatus may provide a variety of application services based on different application properties.

Claims

1. A method for receiving/processing a data broadcast signal supported by a data broadcast platform comprising:

receiving a data broadcast signal including an application information table and an application;

detecting property information indicating a property of the application from the application information table; and

controlling an additional service of the application based on the detected application property information.

2. The method according to claim 1, wherein the application property information is contained in at least one of common and application loops of the application information table.

3. The method according to claim 1, wherein the application property information is contained in at least one of an application property field and an application property descriptor.

4. The method according to claim 1, wherein the application property information includes at least one of recordable information, execution rating information, category information, and runtime information.

5. The method according to claim 4, further comprising:

receiving a recording selection signal indicating a recordable or non-recordable status of a corresponding application based on the recordable information, when the application property information includes the recordable information.

6. The method according to claim 5, further comprising:

receiving the recording selection signal associated with the application, storing the application in a storage medium; and

then if an execution request of the application occurs, reading the corresponding application stored in the storage medium, and executing the read application.

7. The method according to claim 4, further comprising:

displaying an age of a viewable user on the basis of the execution rating information, when the application property information includes the execution rating information.

8. The method according to claim 4, further comprising:

displaying an application preview on the basis of the category information, when the application property information includes the category information.

9. The method according to claim 4, further comprising:

providing an application list for each category on the basis of the category information, when the application property information includes the category information.

10. The method according to claim 4, further comprising:

controlling a reserved recording of a recordable application on the basis of the runtime information, when the application property information includes the runtime time.

11. An apparatus for receiving and processing a data broadcast signal supported by a data broadcast platform comprising:

a receiving unit for receiving a data broadcast signal including an application information table and an application;

a decoder for decoding the received application information table and the received application; and

an application controller for detecting property information indicating a property of the application from the decoded application information table, and controlling an additional service of the application on the basis of the detected application property information.

12. The apparatus according to claim 11, wherein the application property information is contained in at least one of common and application loops of the application information table.

13. The apparatus according to claim 11, wherein the application property information is contained in at least one of an application property field and an application property descriptor.

14. The apparatus according to claim 11, wherein the application property information includes at least one of recordable information, execution rating information, category information, and runtime information.

15. The apparatus according to claim 14, wherein the application controller, if the application property information includes the recordable information, receives a recording selection signal indicating a recordable or non-recordable status of a corresponding application on the basis of the recordable information.

16. The apparatus according to claim 15, wherein the application controller stores the application in a storage medium upon receiving the recording selection signal associated with the application;

and then if an execution request of the application occurs, reads the corresponding application stored in the storage medium and executes the read application.

17. The apparatus according to claim 14, wherein the application controller, if the application property information includes the execution rating information, displays an age of a viewable user on the basis of the execution rating information.

18. The apparatus according to claim 14, wherein the application controller, if the application property information includes the category information, displays an application preview on the basis of the category information.

19. The apparatus according to claim 14, wherein the application controller, if the application property information includes the category information, provides an application list for each category on the basis of the category information.

20. The apparatus according to claim 14, wherein the application controller, if the application property information includes the runtime time, controls a reserved recording of a recordable application on the basis of the runtime information.
