Abstract

Provided are a method and apparatus for receiving, storing, and executing a data broadcast application. The apparatus includes an application controller that determines whether receiving of application data needed to execute an application is completed before storing of a data broadcast is completed, allows the received application data to be stored when receiving of the application is completed, and determines whether the application will be executed together with audio/video data when the stored data broadcast is reproduced; and a storage unit that stores the completely received application data together with the audio/video data. Accordingly, it is possible to prevent the occurrence of errors in executing an application.

Claims

1. An apparatus for receiving and storing a data broadcast application, comprising:

an application controller which determines whether a receiving of application data needed to execute an application is completed when a data broadcast is stored, and which allows the received application data to be stored when the receiving of the application data is completed; and

a storage unit which stores the application data, which is completely received, together with audio/video data.

2. The apparatus of claim 1, wherein the application controller determines whether the receiving of the application is completed by searching a tree structure of an object carousel constructed from the data broadcast, and determines whether an object is received.

3. The apparatus of claim 1, wherein the application controller determines whether the receiving of the application is completed by determining whether all modules described in a control message are received.

4. The apparatus of claim 1, wherein, when a plurality of pieces of application data for a plurality of applications are transmitted, the application controller determines whether receiving of application data to be executed for each of the plurality of applications is completed.

5. The apparatus of claim 2, wherein the tree structure of the object carousel is constructed using a service gateway as a root directory, wherein the service gateway is collected based on an interoperable object reference of a service gateway included in download server indications of the data broadcast.

6. The apparatus of claim 3, wherein the control message is download information indications extracted from a program map table of the data broadcast.

7. An apparatus for executing a data broadcast application, comprising:

a storage unit which stores application data, which is needed to execute an application, together with audio/video data when a data broadcast is stored;

an application controller which determines whether the application is to be executed together with the audio/video data when the stored data broadcast is reproduced; and

an application executing unit selectively which executes the application in response to an instruction from the application controller.

8. The apparatus of claim 7, wherein, when a plurality of pieces of application data for a plurality of applications are stored, the application controller determines whether each of the applications is to be executed.

9. The apparatus of claim 7, wherein the application controller does not allow the application to be executed when not all of the application data are received before storing of the data broadcast is completed.

10. The apparatus of claim 9, wherein the determining of whether receiving of the application data is completed is performed by determining whether all modules described in a control message are received.

11. The apparatus of claim 9, wherein the determining of whether receiving of the application data is completed is performed by searching a tree structure of an object carousel constructed from the data broadcast and determining whether an object is received.

12. The apparatus of claim 10, wherein the control message is download information indications extracted from a program map table of the data broadcast.

13. The apparatus of claim 11, wherein the tree structure of the object carousel is constructed using a service gateway as a root directory and wherein the service gateway is collected based on an interoperable object reference of a service gateway of download server indications of the data broadcast.

14. A method of receiving and storing a data broadcast application, comprising:

determining whether receiving of application data needed to execute an application is completed when a data broadcast is stored; and

when it is determined that receiving of the application data is completed, storing the received application data.

15. The method of claim 14, which is performed for each of a plurality of applications when a plurality of pieces of application data for the plurality of applications are transmitted.

16. The method of claim 14, wherein the determining whether receiving of application data needed to execute an application is completed comprises:

constructing an object tree using a service gateway as a root directory, wherein the service gateway is collected based on an interoperable object reference of a service gateway included in download server indications of the data broadcast; and

extracting an object included in a module based on the interoperable object reference of the service gateway, and determining whether all objects are received by sequentially searching for lower directories based on the extracted object.

17. The method of claim 14, wherein determining whether receiving of application data needed to execute an application is completed comprises:

extracting a control message from a program map table of the data broadcast; and

determining whether all modules described in the control message are received.

18. The method of claim 17, wherein the control message is download information indications extracted from the program map table of the data broadcast.

24. A computer readable medium having recorded thereon a computer program for the method of claims 14 through 23.

19. A method of executing a data broadcast application, comprising:

storing application data, which is needed to execute an application, together with audio/video data when a data broadcast is stored; and

executing the application together with the audio/video data when the stored data broadcast is reproduced.

20. The method of claim 19, wherein, when a plurality of pieces of application data for a plurality of applications are transmitted, determinations are made as to whether each of the applications are to be executed.

21. The method of claim 19, wherein during executing the application, the application is not executed when not all of the application are received before the data broadcast is completed.

22. The method of claim 21, wherein whether receiving of the application data is completed is determined by determining whether all modules described in a control message are received.

23. The method of claim 21, wherein whether receiving of the application data is completed is determined by determining by searching a tree structure of an object carousel constructed from the data broadcast and determining whether an object is received.
