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 non-real time service, the method comprising:

generating the broadcast signal having a non-real time service/content, and signaling data for signaling the non-real time service/content, the non-real time service/content being a broadcast service/content that are delivered in advance of its use,

wherein the signaling data includes a service map table containing service-level attributes for a non-real time broadcasting and a non-real time information table containing information describing non-real time contents available for download to storage in a broadcast receiving device, the service map table including service identifier identifying non-real time service, wherein the service identifier is also used as a linkage to the non-real time information table from the service map table; and

transmitting the non-real time service/content via a broadcast channel and the signaling data via a service signaling channel with a specific Internet Protocol (IP) address and user datagram protocol (UDP) port number;

wherein the non-real time information table includes Uniform Resource Identifier (URI) information specifying at least one uniform resource locator (URL) when retrieving data for the non-real time content via an internet is available;

wherein the non-real time information table further includes a content linkage element to link from the non-real time content to files delivered in one or more File Delivery over Unidirectional Transport (FLUTE) sessions that are components of the non-real time service with which the non-real time content is associated, the files belonging to the non-real time content.

2. The method of claim 1, wherein the non-real time service/content is delivered within IP packets, the IP packets associated with a virtual channel are identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT) table, wherein the IP packets are carried in a Moving Picture Experts Group-2 (MPEG-2) Transport Stream using digital storage media command and control (DSM-CC) Addressable Sections.

3. The method of claim 2, wherein the service signaling channel is carried in a portion of the IP packets.

4. The method of claim 1, the non-real time information table further includes a count information specifying number of the URI information when a plurality of the URI information is included in the non-real time information table.

5. The method of claim 1, the non-real time information table further includes a URI length information specifying length in bytes of the URL.

6. The method of claim 1, the non-real time information table further includes an update information indicating whether the non-real time content is planned to be updated periodically or not.

7. An apparatus for receiving a broadcast signal for non-real time service, the apparatus comprising:

a tuner configured to receive the broadcast signal having a non-real time service/content, and signaling data for signaling the non-real time service/content, the non-real time service/content being a broadcast service/content that are delivered in advance of its use via a broadcast channel, the signaling data being received via a service signaling channel with a specific Internet Protocol (IP) address and user datagram protocol (UDP) port number;

a processor configured to parse a service map table containing service-level attributes for a non-real time broadcasting from the signaling data, obtain service identifier identifying a non-real time service from the service map table, wherein the service identifier is also used as a linkage to a non-real time information table from the service map table, and link to the non-real time information table containing information describing non-real time contents available for download to storage in a broadcast receiving device; and

a storage configured to store the non-real time content based on information of the non-real time information table;

wherein the non-real time information table includes Uniform Resource Identifier (URI) information specifying at least one uniform resource locator (URL) when retrieving data for the non-real time content via an internet is available;

wherein the non-real time information table further includes a content linkage element to link from the non-real time content to files delivered in one or more File Delivery over Unidirectional Transport (FLUTE) sessions that are components of the non-real time service with which the non-real time content is associated, the files belonging to the non-real time content.

8. The apparatus of claim 7, wherein the non-real time service/content is delivered within IP packets, the IP packets associated with a virtual channel are identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT) table, wherein the IP packets are carried in a Moving Picture Experts Group-2 (MPEG-2) Transport Stream using digital storage media command and control (DSM-CC) Addressable Sections.

9. The apparatus of claim 8, wherein the service signaling channel is carried in a portion of the IP packets.

10. The apparatus of claim 7, the non-real time information table further includes a count information specifying number of the URI information when a plurality of the URI information is included in the non-real time information table.

11. The apparatus of claim 7, the non-real time information table further includes a URI length information specifying length in bytes of the URL.

12. The apparatus of claim 7, the non-real time information table further includes an update information indicating whether the non-real time content is planned to be updated periodically or not.
