1. A method of processing a non-real time (NRT) service in a broadcast receiver, the method comprising:
receiving signaling information including a NRT information table describing content items available for download to storage in the broadcast receiver, wherein the NRT information table includes access information which indicates files of a content item among the content items can be accessed by Internet and content linkage information which links metadata in the NRT information table to the files in a File Delivery over Unidirectional Transport (FLUTE) File Delivery Table (FDT), wherein the FLUTE FDT describes linkages between the files; receiving the files through FLUTE sessions based on information in the FLUTE FDT, wherein FLUTE FDT includes content location information specifying locations of the files, and entry file information indicating an entry file among the files, wherein the entry file is to be accessed first before accessing other files of the files for the content item; and providing the NRT service using the files of the content item, wherein the NRT information table further includes an expiration_included field specifying whether an expiration field is included in an iteration of for_loop in the NRT information table, wherein the NRT information table further includes the expiration field representing an expiration time of the content item, wherein the signaling information further includes purchase option information specifying purchasing types for the content items when the content items correspond to purchase content items, wherein the signaling information further includes price information specifying costs of purchases for the content items, wherein the signaling information further includes currency information specifying currencies used to set the costs of the purchases, and wherein the signaling information comprises an NRT content delivery channel descriptor.
