Abstract

A method of processing a non-real time (NRT) service in a broadcast receiver is disclosed where the method includes receiving signaling information including the NRT service information and access information which indicates files of a content item can be accessed by Internet, receiving File Delivery over Unidirectional Transport (FLUTE) files through a FLUTE session, wherein File Delivery Table (FDT) instance of the FLUTE session for each file belonging to the content item includes information for content location of the file, the information for content location including an Uniform Resource Locator (URL), and providing the NRT service using the files belonging to the content item, wherein the files are accessed through the Internet using the URL indicated in the information for content location of the file or accessed through a storage in the broadcast receiver.

Claims

1. A method of processing a non-real time (NRT) service in a broadcast receiver, the method comprising:

receiving signaling information including the NRT service information and access information which indicates files of a content item can be accessed by Internet;

receiving File Delivery over Unidirectional Transport (FLUTE) files through a FLUTE session, wherein File Delivery Table (FDT) instance of the FLUTE session for each file belonging to the content item includes information for content location of the file, the information for content location including an Uniform Resource Locator (URL); and

providing the NRT service using the files belonging to the content item, wherein the files are accessed through the Internet using the URL indicated in the information for content location of the file or accessed through a storage in the broadcast receiver.

2. The method of claim 1, wherein the NRT service information includes an entry file indicating that a file is to be accessed first before accessing other files.

3. The method of claim 2, wherein the NRT service information includes a descriptor including the information on the entry file, and wherein the information on the entry file includes a file name of the entry file.

4. The method of claim 1, wherein the NRT service information includes NRT service signaling table, NRT service map table, and NRT information table.

5. The method of claim 1, wherein when files are accessed only via the FLUTE session, the files are accessed by using absolute tag URL or relative URL.

6. The method of claim 5, wherein when the files are accessed using absolute tag URL, that URL is an absolute URL for the file.

7. The method of claim 5, wherein when the files are accessed using relative URL, the file has an URL of form file:

//X/<

content-location>

, where X is an arbitrary virtual folder known to the broadcast receiver.

8. The method of claim 6, wherein the tag URL is to be globally unique and determined in the FLUTE session.

9. The method of claim 1, wherein the FLUTE files that are not available over the Internet have either a relative URL or an absolute tag Uniform Resource Identifier (URI) as the content location value.

10. A broadcast receiver to process a non-real time service, the broadcast receiver comprising:

a signaling information processor for receiving signaling information including the NRT service information and access information which indicates files of a content item can be accessed by Internet;

a file processor for receiving File Delivery over Unidirectional Transport (FLUTE) files through a FLUTE session, wherein File Delivery Table (FDT) instance of the FLUTE session for each file belonging to the content item includes information for content location of the file, the information for content location including an Uniform Resource Locator (URL); and

a service processor for providing the NRT service using the files belonging to the content item, wherein the files are accessed through the Internet using the URL indicated in the information for content location of the file or accessed through a storage in the broadcast receiver.

11. The broadcast receiver of claim 10, wherein NRT service information includes an entry file indicating that a file is to be accessed first before accessing other files.

12. The broadcast receiver of claim 11, wherein the NRT service information includes a descriptor including the information on the entry file, and wherein the information on the entry file includes a file name of the entry file.

13. The broadcast receiver of claim 10, wherein the NRT service information includes NRT service signaling table, NRT service map table, and NRT information table.

14. The broadcast receiver of claim 10, wherein when files are accessed only via the FLUTE session, the files are accessed by using absolute tag URL or relative URL.

15. The broadcast receiver of claim 10, wherein when the files are accessed using absolute tag URL, that URL is an absolute URL for the file.

16. The broadcast receiver of claim 15, wherein when the files are accessed using relative URL, the file has an URL of form file:

//X/<

content-location>

, where X is an arbitrary virtual folder known to the broadcast receiver.

17. The broadcast receiver of claim 15, wherein the tag URL is to be globally unique and determined in the FLUTE session.

18. The broadcast receiver of claim 10, wherein the FLUTE files that are not available over the Internet have either a relative URL or an absolute tag Uniform Resource Identifier (URI) as the content location value.
