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 a signaling information table including access information of the NRT service, receiving data of the NRT service based on the signaling information table in non-real time and storing the received data of the NRT service in a storage medium, extracting service information including service type of the NRT service and detail information of the NRT service from the signaling information table, and controlling processes of the NRT service based on the extracted service information.

Claims

1. A method of receiving a non-real time service, the method comprising:

receiving a broadcast signal including IP datagrams, the IP datagrams containing one or more non-real time services, which associated with one or more content items, that are delivered in advance of its use and stored in a receiving device, first signaling data containing service-level attributes for the non-real time service, and second signaling data including a service fragment and a content fragment of a service guide for the non-real time service;

identifying the one or more non-real time services based on the first signaling data; and

constructing a service guide for the one or more non-real time services based on the second signaling data,

wherein the content item is composed of one or more files being delivered via a File Delivery over Unidirectional Transport (FLUTE) file delivery session,

wherein the service fragment includes an element indicating that the service fragment contains information regarding the identified non-real time service,

and wherein the content fragment includes a linkage element linking from a content item to one or more files, the linking element having an identifier of the content item, the identifier of the content item being used to map one or more files to the content item with a content identifier included in a FLUTE File Description Table (FDT) instance for the non-real time service.

2. The method of claim 1, wherein the first signaling data is encapsulated using a user datagram protocol/internet protocol (UDP/IP) method and the second signaling data is sequentially encapsulated using a FLUTE method and the UDP/IP method.

3. The method of claim 2, wherein the first signaling data is acquired via a service signaling channel (SSC) with a specific IP address and UDP port number.

4. The method of claim 3, wherein each file associated with the content item represented by the content fragment has a content linkage tag matching a value of content linkage tag included in a FLUTE FDT instance.

5. The method of claim 4, further comprises downloading one or more content items of the non-real time service being selected from the service guide.

6. The method of claim 1, wherein the FLUTE FDT includes information indicating an attribute that identifies the file as an entry point of the content item identified by the parameter, the entry point is presented initially the file of the content item by the receiving device.

7. The method of claim 1, wherein the first signaling data includes not only an IP address and UDP ports but also transport session identifiers (TSIs) of the FLUTE sessions.

8. An apparatus of receiving a non-real time service, the apparatus comprising:

a tuner configured to receive a broadcast signal including IP datagrams, the IP datagrams containing one or more non-real time services, which associated with one or more content items, that are delivered in advance of its use and stored in a receiving device, first signaling data containing service-level attributes for the non-real time service, and second signaling data including a service fragment and a content fragment of a service guide for the non-real time service; and

a processor configured to identify the one or more non-real time services based on the first signaling data, and construct a service guide for the one or more non-real time services based on the second signaling data; and

a storage configured to store the constructed service guide,

wherein the content item is composed of one or more files being delivered via a File Delivery over Unidirectional Transport (FLUTE) file delivery session,

wherein the service fragment includes an element indicating that the service fragment contains information regarding the identified non-real time service,

and wherein the content fragment includes a linkage element linking from a content item to one or more files, the linkage element having an identifier of the content item, the identifier of the content item being used to map one or more files to the content item with a content identifier included in a FLUTE File Description Table (FDT) instance for the non-real time service.

9. The apparatus of claim 8, wherein the first signaling data is encapsulated using a user datagram protocol/internet protocol (UDP/IP) method and the second signaling data is sequentially encapsulated using a FLUTE method and the UDP/IP method.

10. The apparatus of claim 9, wherein the first signaling data is acquired via a service signaling channel (SSC) with a specific IP address and UDP port number.

11. The apparatus of claim 10, wherein each file associated with the content item represented by the content fragment has a content linkage tag matching a value of content linkage tag included in a FLUTE FDT instance.

12. The apparatus of claim 11, wherein the processor is further configured to download one or more content items of the non-real time service being selected from the service guide.

13. The apparatus of claim 12, wherein the FLUTE FDT includes information indicating an attribute that identifies the file as an entry point of the content item identified by the parameter, the entry point is presented initially the file of the content item by the receiving device.

14. The apparatus of claim 13, wherein the first signaling data includes not only an IP address and UDP ports but also transport session identifiers (TSIs) of the FLUTE sessions.
