Abstract

A method of receiving and process a broadcast signal including a Non-Real Time (NRT) service and a broadcast receiver are disclosed herein. A method of processing a broadcast signal including a Non-Real Time (NRT) service, the method comprises receiving and processing a signaling information table including access information of the NRT service, receiving and storing data of the NRT service based on the signaling information table in non-real time, extracting access information of additional information relating to the NRT service from the signaling information table, and downloading the additional information relating to the NRT service based on the extracted access information.

Claims

1. A method of transmitting a broadcast signal for a broadcast service, the method comprising:

generating the broadcast signal having the broadcast service that includes a non-real time content, and signaling data for signaling the broadcast service,

wherein the signaling data includes a service information element containing service-level attributes for the broadcast service and a non-real time information element containing information describing the non-real time content for the broadcast service, and

wherein the service information element includes a service identifier identifying the broadcast service; and

transmitting the broadcast service and the signaling data via a broadcast channel,

wherein the service information element further includes status information identifying a status of the broadcast service,

wherein the signaling data further includes source IP address information specifying a source address of an IP datagram carrying the broadcast service, and

wherein the service information element further includes information related to a component of the broadcast service carried via a transport session over the broadcast channel.

2. The method of claim 1, wherein the non-real time information element further includes Forward Error Correction (FEC) coding information specifying which FEC encoding method is applied to the files.

3. The method of claim 1, wherein the non-real time information element further includes update information specifying whether the non-real time content is available for being updated periodically.

4. The method of claim 1, wherein the non-real time information element further includes file location information specifying a location of a file which can be provided separately via an internet protocol.

9. The method of claim 1, wherein [the] a related file of the non-real time content provides a part of an additional content information,

wherein the additional content information includes one of a trailer of preview, logo, poster, still-image, commercial, music video, and original sound track (OST).

11. The method of claim 1, wherein the non-real time information element further includes a related information reference element representing reference information of a related file of the non-real time content.

13. The method of claim 1, wherein the non-real time information element further includes content level descriptor providing information on internet location of the non-real time content,

wherein the content level descriptor includes Uniform Resource Locator (URL) information indicating an internet URL for the non-real time content, and recommended speed information indicating a recommended internet speed value considering a size of the non-real time content.

5. An apparatus for receiving a broadcast signal for a broadcast service, the apparatus comprising:

a tuner that receives the broadcast signal having the broadcast service that includes a non-real time content, and signaling data for signaling the broadcast service;

a processor that parses a service information element and a non-real time information element from the signaling data,

wherein the service information element contains service-level attributes for the broadcast service,

wherein the non-real time information element contains information describing the non-real time content for the broadcast service; and

wherein the service information element includes a service identifier identifying the broadcast service; and

a storage that stores the non-real time content based on the non-real time information element,

wherein the service information element further includes status information identifying a status of broadcast service,

wherein the signaling data further includes source IP address information specifying a source address of an IP datagram carrying the broadcast service, and

wherein the service information element further includes information related to a component of the broadcast service carried in a transport session over the broadcast channel.

6. The apparatus of claim 5, wherein the non-real time information element further includes Forward Error Correction (FEC) coding information specifying which FEC encoding method is applied to the files.

7. The apparatus of claim 5, wherein the non-real time information element further includes update information specifying whether the non-real time content is available for being updated periodically.

8. The apparatus of claim 5, wherein the non-real time information element further includes file location information specifying a location of a file which can be provided separately via an internet protocol.

10. The apparatus of claim 5, wherein a related file of the non-real time content provides a part of an additional content information,

wherein the additional content information includes one of a trailer of preview, logo, poster, still-image, commercial, music video, and original sound track (OST).

12. The method of claim 5, wherein the non-real time information element further includes a related information reference element representing reference information of a related file of the non-real time content.

14. The apparatus of claim 5, wherein the non-real time information element further includes content level descriptor providing information on internet location of the non-real time content,

wherein the content level descriptor includes Uniform Resource Locator (URL) information indicating an internet URL for the non-real time content, and recommended speed information indicating a recommended internet speed value considering a size of the non-real time content.
