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. 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 Table (NRT-IT) describing one or more content items in the NRT service available for download to storage in the receiving device and a Service Map Table (SMT) containing information used as a linkage between the SMT and the NRT-IT; and

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

wherein the NRT service is delivered within IP packets, wherein 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), wherein the IP packets are carried in MPEG-2 Transport Stream using Digital Storage Media Command and Control (DSM-CC) Addressable Section format, and

wherein the NRT-IT is composed of at least one NRT-IT instance,

wherein the NRT-IT instance includes data corresponding to an arbitrarily defined time period,

wherein the NRT-IT instance includes information indicating a start time of a period covered by the NRT-IT instance and information indicating a length of the period covered by the NRT-IT instance.

2. The method of claim 1, wherein the NRT-IT includes a title of the content item, times during which the content item is to be made available for download, and content advisories, availability of caption services, content identification information of the content item.

3. The method of claim 1, wherein each content item includes at least one file.

4. The method of claim 1, wherein periods of NRT-IT instances for same NRT service do not overlap.

5. The method of claim 1, wherein the SSC is carried in a portion of the IP packets.

6. The method of claim 5, wherein the SMT is linked to the NRT-IT and carried through the SSC, the SMT describing one or more NRT services, and the NRT-IT providing descriptive metadata about the content items that make up the NRT service.

7. 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 Table (NRT-IT) describing one or more content items in the NRT service available for download and a Service Map Table (SMT) containing information used as a linkage to the NRT-IT;

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 service signaling channel (SSC) with a specific IP address and UDP port number,

wherein the NRT service is delivered within IP packets, wherein 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), wherein the IP packets are carried in MPEG-2 Transport Stream using Digital Storage Media Command and Control (DSM-CC) Addressable Section format,

wherein the NRT is composed of at least one NRT-IT instance,

wherein the NRT-IT instance includes data corresponding to an arbitrarily defined time period, and

wherein the NRT-IT instance includes information indicating a start time of a period covered by the NRT-IT instance and information indicating a length of the period covered by the NRT-IT instance.

8. The apparatus of claim 7, wherein the NRT-IT includes a title of the content item, times during which the content item is to be made available for download, and content advisories, availability of caption services, content identification information of the content item.

9. The apparatus of claim 7, wherein the content item includes at least one file.

10. The apparatus of claim 7, wherein periods of NRT-IT instances for same NRT service do not overlap.

11. The apparatus of claim 7, wherein the SSC is carried in a portion of the IP packets.

12. The apparatus of claim 11, wherein the SMT is linked to the NRT-IT and carried through the SSC, the SMT describing one or more NRT services, and the NRT-IT providing descriptive metadata about the content items that make up the NRT service.
