Abstract: A broadcast reception apparatus includes a packet receiver to receive transport packets for signaling data through a dedicated transport channel, and receive transport packets for a delivery object through other transport channels, wherein the delivery object is a part of a file for video content of a broadcast service, a signaling parser to extract the signaling data including session description information and an extended file delivery table providing information about delivery of the file, and a data processor to recover the delivery object based on the signaling data, and generate location information for the file by substituting file template information included in the extended file delivery table with a Transport Object Identifier (TOI) in a header of a transport packet for the delivery object.
