Abstract

A method of processing a web service in a Non-Real Time (NRT) service and the broadcast receiver are disclosed herein. A method of providing an NRT service in a broadcasting receiver may include receiving first signaling information, identifying whether a service type of an NRT service is a web service based upon the first signaling information, identifying a web page type and a web page version of the NRT service and browsing the NRT service. The method may further include connecting a service signaling channel, parsing the received first signaling information, determining whether the NRT service is supported in the broadcasting receiver and consuming the web contents of the NRT service. The NRT service may include at least one of a fixed NRT service and a mobile NRT service. The first signaling information may be a data casting description table (DDT) if the NRT service is the fixed NRT service. The first signaling information may be a service map table (SMT) if the NRT service is the mobile NRT service. The DDT may include a first field identifying the NRT service and a second field identifying a type of the NRT service. The type of the web service may include at least one of a web document of text HTML and a web document of CE-HTML. The third field and the fourth field may be valid if the type of the received service is the web service based upon the second field.

Claims

1. A method of providing a Non-Real Time (NRT) service in a broadcasting receiver, the method comprising:

receiving first signaling information;

identifying whether a service type of an NRT service is a web service based upon the first signaling information;

identifying a web page type and a web page version of the NRT service; and

browsing the NRT service.

2. The method of claim 1, further comprising:

connecting a service signaling channel;

parsing the received first signaling information;

determining whether the NRT service is supported in the broadcasting receiver; and

consuming the web contents of the NRT service.

3. The method of claim 2, wherein the NRT service includes at least one of a fixed NRT service and a mobile NRT service.

4. The method of claim 3, wherein the first signaling information is a data casting description table (DDT) if the NRT service is the fixed NRT service.

5. The method of claim 3, wherein the first signaling information is a service map table (SMT) if the NRT service is the mobile NRT service.

6. The method of claim 4, wherein the DDT includes a first field identifying the NRT service and a second field identifying a type of the NRT service.

7. The method of claim 6, wherein the type of the web service includes at least one of a web document of text HTML and a web document of CE-HTML.

8. The method of claim 7, wherein the third field and the fourth field is valid if the type of the received service is the web service based upon the second field.

9. A method of providing a Non-Real Time (NRT) service in a broadcasting receiver, the method comprising;

receiving first signaling information through a service signaling channel;

processing the first signaling information;

determining whether a service is an NRT service;

determining whether the NRT service is a web service based upon the first signaling information;

identifying a web page type and a web page version of the NRT web service; and

browsing the NRT web service.

10. The method of claim 9, further comprising:

connecting a service signaling channel;

determining whether the NRT service is supported in the broadcasting receiver; and

15. The method of claim 10, wherein the web page type is included at least one of a web document of text HTML and a web document of CE-HTML.

16. The method of claim 15, wherein the web page type and the web page version is valid if the type of the received service is the web service based upon the second field.

17. A method of providing a Non-Real Time (NRT) service in a broadcasting receiver, the method comprising:

receiving first and second signaling information;

determining whether a service is an NRT service based upon the first signaling information;

identifying that content information of the NRT service is a web type information based upon the second signaling information; and

displaying the content information in a format of the web.

18. The method of claim 17 further comprises downloading corresponding content based upon the displayed content information.

19. The method of claim 18, wherein the content information further includes announcement information of a content.

20. The method of claim 19, wherein the first signaling information is an NRT service table (NST) and the second signaling information is an NRT content table (NCT).

21. The method of claim 20, further comprising:

identifying whether the content information is supported in the broadcasting receiver;

storing the downloaded content information.

22. A broadcasting receiver, comprising:

a receiving unit for receiving first signaling information;

a controller for controlling to determine whether a service type of an NRT service is a web service based upon the received first signaling information and identify a web page type and a web page version of the NRT service; and

a display unit for browsing the NRT service.

23. The broadcasting receiver of claim 22, wherein the controller further controls to download a web content in the NRT service based upon the received first signaling information.

24. The broadcasting receiving of claim 23, wherein the controller further controls to determine whether the NRT service is supported in the broadcasting receiver.

25. A broadcasting receiver, comprising:

a receiving unit for receiving first signaling information through a service signaling channel;

a controller for controlling to determine whether a service is a Non-Real Time (NRT) service, determine whether the NRT service is a web service based upon the received first signaling information and identify a web page type and a web page version of the NRT web service; and

a display unit for browsing the NRT web service.

26. The broadcasting receiver of claim 25 further comprises a storage unit for storing the NRT web service.

27. The broadcasting receiver of claim 26, wherein the controller further controls to download a web content in the NRT service based upon the received first signaling information.

28. The broadcasting receiving of claim 27, wherein the controller further controls to determine whether the NRT service is supported in the broadcasting receiver.
