Abstract

A method for mapping signaling information to announcement information and a broadcast receiver are disclosed herein. A method of providing a Non-Real-Time (NRT) service, the method comprises extracting identification information of first signaling information and second signaling information based upon a program specific information/program and system information protocol (PSI/PSIP) table, receiving the first signaling information and second signaling information based upon the extracted identification information, constructing and displaying a service guide using the received first signaling information, acquiring first content identification information as a content selected from the displayed service guide, accessing a File Delivery over Unidirectional Transport (FLUTE) session using the received second signaling information, acquiring second content identification information matched with the acquired first content identification information from the accessed FLUTE session and receiving and storing one or more file constructing corresponding content based upon the acquired second content identification information.

Claims

1. A method of transmitting a non-real time service, the method comprising:

generating a broadcast signal including the non-real time service that is delivered in advance of its use and stored in a receiving device, and signaling data including a non-real time information table describing one or more content items available for download to storage in the receiving device; and

transmitting the non-real time service via a broadcast channel and transmitting the signaling data via a service signaling channel with a specific Internet protocol (IP) address and port number,

wherein the non-real time service is delivered within IP packets, the IP packets associated with a virtual channel identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT),

wherein the IP packets are carried in an MPEG-2 Transport Stream using DSM-CC Addressable Sections,

wherein the service signaling channel is carried in a portion of the IP packets,

wherein the non-real time service is associated with one or more content items, each of which consists of one or more files,

wherein the non-real time information table comprises first information specifying an identification number of a content item and performing a linkage function between the content item and the one or more files,

wherein the one or more files are listed in a File Delivery over Unidirectional Transport (FLUTE) File Delivery Table (FDT),

wherein the FLUTE FDT is linked to the first information of the non-real time information table to identify the content item to which the one or more files belong,

wherein the signaling data further include a service map table containing service-level attributes for the non-real time service, and

wherein the service map table includes second information identifying the non-real time service and third information indicating that a category of a service is a non-real time service, the service map table linked to the non-real time information table through the second information of the service map table.

2. The method of claim 1, wherein the PMT provides mappings between program numbers and one or more program elements which contain MPEG-2 TS packets carrying IP multicast packets encapsulated in the DSM-CC addressable sections for the non-real time service and including a packet identifier (PID) referencing the DSM-CC addressable sections.

3. The method of claim 2, wherein the VCT provides an attribute of the virtual channel and contains information indicating that a type of a service is a non-real time service.

4. The method of claim 1, wherein the FLUTE FDT includes information indicating an attribute that identifies a file as an entry point of the content item identified by a parameter, the entry point presented initially for the file by the receiving device.

5. An apparatus for receiving a non-real time service, the apparatus comprising:

a tuner configured to receive a broadcast signal including the non-real time service that is delivered in advance of its use and stored in a receiving device, and signaling data for the non-real time service, the non-real time service received 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 non-real time information table for the non-real time service from the signaling data, the non-real time information table describing one or more content items available for download to storage in the receiving device; and

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

wherein the non-real time service is delivered within IP packets, the IP packets associated with a virtual channel identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT),

wherein the IP packets are carried in an MPEG-2 Transport Stream using DSM-CC Addressable Sections,

wherein the service signaling channel is carried in a portion of the IP packets,

wherein the non-real time service is associated with one or more content items, each of which consists of one or more files,

wherein the non-real time information table comprises first information specifying an identification number of a content item and performing a linkage function between the content item and the one or more files,

wherein the one or more files are listed in a File Delivery over Unidirectional Transport (FLUTE) File Delivery Table (FDT),

wherein the processor is further configured to identify the content item to which the one or more files belong from a linkage between the FLUTE FDT and the first information of the non-real time information table,

wherein the processor is further configured to parse a service map table containing service-level attributes for the non-real time service from the signaling data, and

wherein the processor is further configured to extract second information identifying the non-real time service from the service map table and third information indicating that a category of a service is a non-real time service from the service map table, the service map table linked to the non-real time information table through the second information of the service map table.

6. The apparatus of claim 5, wherein the processor is further configured to parse the PMT providing mappings between program numbers and one or more program elements which contain MPEG-2 TS packets carrying IP multicast packets encapsulated in the DSM-CC addressable sections for the non-real time service, the PMT including a packet identifier (PID) referencing the DSM-CC addressable sections.

7. The apparatus of claim 6, wherein the processor is further configured to parse the VCT, the VCT providing an attribute of the virtual channel and containing information indicating that a type of a service is a non-real time service.

8. The apparatus of claim 5, wherein the processor is further configured to extract information indicating an attribute that identifies a file as an entry point of the content item identified by a parameter, the entry point presented initially for the file of the content item by the receiving device from the FLUTE FDT.
