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.

First claim

The invention claimed is:

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:
