Abstract

A broadcast service receiving method of a broadcast receiving device provided. The method includes: receiving a trigger including location information of a bookmark target object; extracting the location information of the bookmark target object from the trigger; receiving bookmark target object related information including bookmark signaling data by using the location information of the bookmark target object; extracting the bookmark signaling data from the bookmark target object related information; when the bookmark signaling data is extracted, displaying that a bookmark target object is able to be bookmarked; when a user input for bookmarking the bookmark target object is received, saving the location information of the bookmark target object; and displaying location information of a saved bookmark target object at a predetermined time.

Claims

1. A method for a broadcast device to receive a broadcast comprising:

receiving a trigger including an identifier for a trigger declarative object (TDO); and

executing the TDO based on the trigger to save a bookmark of an adjunct service,

wherein the adjunct service is related to a television program currently displayed by the broadcast device,

wherein receiving a trigger including an identifier for a trigger declarative object (TDO) comprises,

receiving Digital TV Closed Caption (DTV-CC) and

extracting the trigger from the DTV-CC.

2. The method claim 1, wherein the executing the TDO based on the trigger to save a bookmark of an adjunct service comprises:

saving an expiration time of the bookmark and

removing the bookmark after the expiration time.

3. The method claim 1, wherein the executing the TDO based on the trigger to save a bookmark of an adjunct service comprises:

saving a name and a number of a television channel which offered the adjunct service.

4. The method claim 1, wherein the executing the TDO based on the trigger to save a bookmark of an adjunct service comprises:

saving a name of the television program which offered the adjunct service.

5. The method claim 1, wherein the executing the TDO based on the trigger to save a bookmark of an adjunct service comprises:

saving the location of a thumbnail which represents the bookmark.

6. The method claim 1, wherein the executing the TDO based on the trigger to save a bookmark of an adjunct service comprises;

saving a time the bookmark is saved.

7. The method claim 1, further comprising:

displaying the bookmark as icon array format.

8. The method claim 1, further comprising:

receiving a user input for executing the bookmark; and

executing the bookmark based on the user input.

9. The method claim 1, further comprising;

receiving a user input for deleting the bookmark; and

deleting the bookmark based on the user input.

10. An apparatus for receiving a broadcast service, comprising:

a trigger receiver to receive Digital TV Closed Caption (DTV-CC), and extract a trigger, from the DTV-CC, including an identifier for identifying a triggered declarative object (TDO); and

a TDO module to execute the TDO based on the trigger to save a bookmark of an adjunct service,

wherein the adjunct service is related to a television program currently displayed by the broadcast device.

11. The apparatus of claim 10, wherein the TDO module saves an expiration time of the bookmark, and removes the bookmark after the expiration time.

12. The apparatus of claim 10, wherein the TDO module saves a name and a number of a television channel which offered the adjunct service.

13. The apparatus of claim 10, wherein the TDO module saves a name of the television program which offered the adjunct service.

14. The apparatus of claim 10, wherein the TDO module saves the location of a thumbnail which represents the bookmark.

15. The apparatus of claim 10, wherein the TDO module saves a time the bookmark is saved.

16. The apparatus of claim 10, wherein the TDO module displays the bookmark as icon array format.

17. The apparatus of claim 10, further comprising:

a user interface to receive a user input to execute the bookmark; and

a bookmark module to execute the bookmark base on the user input.

18. The apparatus of claim 10, further comprising:

a user interface to receive a user input for deleting the bookmark; and

a bookmark module to delete the bookmark based on the user input.
