Abstract

A method of receiving and processing a broadcast signal including a Non-Real Time (NRT) service and a broadcast receiver are disclosed herein. A method of processing a Non-Real Time (NRT) service in a broadcast receiver, the method comprises receiving and processing first signaling information including content access information and second signaling information including content detail information, receiving and processing third signaling information including content update information, receiving and storing a content including at least one file through NRT based on the first signaling information and the second signaling information, identifying update availability of the content based on the content update information included in the third signaling information, and receiving at least one file included in the content by accessing a File Delivery over Unidirectional Transport (FLUTE) session transmitting the content when the update is available.

Claims

1-20. -20. (canceled)

21. A method of transmitting a broadcast signal for a Non-Real Time (NRT) service, the method comprising:

generating the broadcast signal including the NRT service that is delivered in advance of its use and stored in a receiving device, and signaling data including an NRT Information element describing one or more content items in the NRT service available for download to storage in the receiving device; and

transmitting the NRT service in advance of its use via a broadcast channel and the signaling data via a signaling channel with a specific IP address and UDP port number,

wherein the NRT service is delivered within IP packets,

wherein each of the content items consists of one or more files,

wherein the NRT Information element includes content linkage information of which value is matched with the one or more files to identify a content item to which the one or more files belong, and

wherein the NRT Information element further includes content size information representing total size of the content item, wherein the content size information is used by the receiving device to determine if enough memory is available to store the content item before downloading is attempted.

22. The method of claim 21, wherein the NRT Information element further includes content size inclusion information indicating whether the content size information is present for the content item.

23. The method of claim 21, wherein the content item corresponds an ancillary content which provides more specific information related to a real-time content.

24. The method of claim 23, wherein the content item delivered in NRT is to be combined with the real-time content to provide a complete content.

25. An apparatus for receiving a broadcast signal for a Non-Real Time (NRT) service, the apparatus comprising:

a tuner configured to receive the broadcast signal including the NRT service and signaling data including an NRT Information element describing one or more content items in the NRT service available for download;

a non-transitory storage medium configured to store the NRT service that is received in advance of its use; and

an NRT service manager configured to manage the stored NRT service,

wherein the NRT service is received via a broadcast channel and the signaling data are received via a signaling channel with a specific IP address and UDP port number,

wherein the NRT service is delivered within IP packets,

wherein each of the content items consists of one or more files,

wherein the NRT Information element includes content linkage information of which value is matched with the one or more files to identify a content item to which the one or more files belong,

wherein the NRT Information element further includes content size information representing total size of the content item, and

wherein NRT service manager is further configured to determine if enough memory is available to store the content item before downloading is attempted using the content size information.

26. The apparatus of claim 25, wherein the NRT Information element further includes content size inclusion information indicating whether the content size information is present for the content item.

27. The apparatus of claim 25, wherein the content item corresponds an ancillary content which provides more specific information related to a real-time content.

28. The apparatus of claim 27, wherein the NRT service manager is further configured to combine the content item delivered in NRT with the real-time content to provide a complete content.
