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 a service by a transmission system, the method comprising:

generating internet protocol (IP) datagrams including one or more content items for the service,

service signaling information containing service-level attributes for the service and service guide information containing a content fragment for describing the content items for the service,

wherein the service signaling information includes identification information identifying the service, status information specifying whether the service is active or inactive and name information indicating a name of the service; and

transmitting a broadcast signal including the generated IP datagrams,

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

wherein the broadcast signal includes a File Delivery Table (FDT) instance including first linkage information, the first linkage information is related to associating the files with the content items, the service guide information includes second linkage information, the second linkage information is related to associating the content fragment with the files.

2. The method of claim 1, wherein each of the LCT sessions includes one or more channels.

3. The method of claim 1, wherein the service guide information further contains a service fragment, a schedule fragment, and an access fragment for the service.

4. An apparatus for receiving a service, the apparatus comprising:

a tuner configured to receive a broadcast signal including one or more content items for the service,

service signaling information containing service-level attributes for the service and service guide information containing a content fragment for describing the content items for the service,

wherein the service signaling information includes identification information identifying the service, status information specifying whether the service is active or inactive and name information indicating a name of the service; and

a storage configured to store the received one or more content items, the service signaling information and the service guide information,

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

wherein the broadcast signal includes a File Delivery Table (FDT) instance including first linkage information, the first linkage information is related to associating the files with the content items, the service guide information includes second linkage information, the second linkage information is related to associating the content fragment with the files.

5. The apparatus of claim 4, wherein each of the LCT sessions includes one or more channels.

6. The apparatus of claim 4, wherein the service guide information further contains a service fragment, a schedule fragment, and an access fragment for the service.
