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 ### Claim 1 A method of receiving a non-real time service, the method comprising: receiving 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 for the non-real time service and a service map table containing service-level attributes for the non-real time service, the signaling data carried in a service signaling channel with a specific internet protocol (IP) address and a port number; and outputting the non-real time service based on the signaling data, 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 Digital Storage Media-Command and Control (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 which are listed in a File Delivery over Unidirectional Transport (FLUTE) File Delivery Table (FDT), wherein the non-real time information table comprises linkage information performing a linkage function between the content item and the one or more files, wherein the FLUTE FDT is linked to the linkage information of the non-real time information table to identify the content item to which the one or more files belong, and wherein the service map table includes first information identifying the non-real time service and second 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 first information of the service map table. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 2) The method of claim 2, wherein the VCT provides an attribute of the virtual channel and includes information indicating that a type of the service is a non-real time service. ### Claim 4 (depends on 1) 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 of the content item by a receiving device. ### Claim 5 An apparatus for transmitting a non-real time service, the apparatus comprising: a generating unit configured to generate 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 carried in a service signaling channel with a specific internet protocol (IP) address and user datagram protocol (UDP) port number, the signaling data including a non-real time information table describing one or more content items available for download to storage in the receiving device for the non-real time service and a service map table containing service-level attributes for the non-real time service; and a transmitting unit configured to transmit the generated broadcast signal, wherein the non-real time service is delivered within IP packets which are associated with a virtual channel identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT), the IP packets carried in an MPEG-2 Transport Stream using Digital Storage Media-Command and Control (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 which are listed in a File Delivery over Unidirectional Transport (FLUTE) File Delivery Table (FDT), wherein the non-real time information table comprises first information performing a linkage function between the content item and the one or more files, 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, and wherein the service map table includes first information identifying the non-real time service and second 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 first information of the service map table. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the generating unit is further configured to generate 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. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the generating unit is further configured to generate the VCT that provides an attribute of the virtual channel and including information indicating that a type of the service is a non-real time service. ### Claim 8 (depends on 5) The apparatus of claim 5, wherein the generating unit is further configured to generate 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 a receiving device from the FLUTE FDT.
