Abstract

A method of receiving a broadcast signal including a Non-Real-Time (NRT) service and a broadcast receiver are disclosed herein. A method of receiving a broadcast signal including a Non-Real-Time (NRT) service, the method comprises receiving a broadcast signal including an NRT content and NRT service guide information, the NRT service guide information including a content fragment, identifying a File Delivery over Unidirectional Transport (FLUTE) session delivering the NRT content from the broadcast signal, detecting a first content identification information from a File Description Table (FDT) of the FLUTE session, and detecting a second content identification information of the content fragment matched with the first content identification information.

Claims

1. A method of transmitting non-real time (NRT) service, the method comprising:

generating internet protocol (IP) datagrams including the NRT service that is delivered in advance of its use and stored in a receiving device, and signaling data including a service description containing service-level attributes for the NRT service and a service guide (SG) containing a content fragment announcing the NRT service; and

transmitting a broadcast signal including the generated IP datagrams,

wherein the NRT service is associated with one or more content items, each of which consists of one or more files being delivered via a Layered Coding Transport (LCT) sessions,

wherein both the content items and the files are linked by matching values of first linkage elements defined for the files in a File Delivery Table (FDT) with values of second linkage elements in the content fragment of the SG, and

wherein each of the LCT sessions includes one or more channels.

2. The method of claim 1, wherein the NRT service is further signaled based on a hierarchical structure in which two distinct steps:

a first step being an ensemble access step through a Fast Information Channel (FIC) providing binding information between service identifiers and ensembles, and

a second step being an IP level service access step through the service description.

3. The method of claim 1, wherein the FDT further includes a Transport Object Identifier (TOI) and Content_Location element of the files.

4. The method of claim 1, wherein the service description further includes parameters of one or more LCT sessions where the files associated with the NRT service.

5. The method of claim 1, wherein the SG further contains a service fragment, a schedule fragment, and an access fragment for the NRT service.

6. An apparatus for receiving non-real time (NRT) service, the apparatus comprising:

a tuner configured to receive a broadcast signal including the NRT service that is delivered in advance of its use and stored in a receiving device, and signaling data including a service description containing service-level attributes for the NRT service and a service guide (SG) containing a content fragment announcing the NRT service; and

a storage configured to store the NRT service and the signaling data,

wherein the NRT service is associated with one or more content items, each of which consists of one or more files being delivered via a Layered Coding Transport (LCT) session,

wherein both the content items and the files are linked by matching values of first linkage elements defined for the files in a File Delivery Table (FDT) with values of second linkage elements in the content fragment of the SG,

wherein each of the LCT sessions includes one or more channels.

7. The apparatus of claim 6, wherein the NRT service is further signaled based on a hierarchical structure in which two distinct steps:

a first step being an ensemble access step through a Fast Information Channel (FIC) providing binding information between service identifiers and ensembles, and

a second step being an IP level service access step through the service description.

8. The apparatus of claim 6, wherein the FDT further includes a Transport Object Identifier (TOI) and Content_Location element of the files.

9. The apparatus of claim 6, wherein the service description further includes parameters of one or more LCT sessions where the files associated with the NRT service.

10. The apparatus of claim 6, wherein the SG further contains a service fragment, a schedule fragment, and an access fragment for the NRT service.
