Abstract: An apparatus for receiving a broadcast signal, the apparatus including a tuner configured to receive transport packets for signaling data and transport packets for delivery objects, a delivery object is a part of a file for video content of a broadcast service: a signaling parser configured to parse the signaling data including session information including an extended file delivery table providing information about delivery of the file, in which the extended file delivery table including file template information: and a data processor configured to generate location information for the file by substituting an identifier in the file template information with a Transport Object Identifier (TOI) in a header of a transport packet for the delivery object. Further, a payload of the transport packet for the delivery object carries a contiguous portion of the delivery object starting from a beginning of a first byte value through a byte value related to a sum of the first byte value and second byte value, the first byte value is a value of start offset information, that is followed by the payload, in the transport packet, and the second byte value is a length of the payload computed by subtracting a size of the header and a size of the start offset information from a total length of the transport packet.

Abstract: An apparatus for transmitting a broadcast signal includes a processor configured to format a plurality of Internet Protocol (IP) packets to output one or more Physical Layer Pipes (PLPs). Further, the plurality of IP packets includes signaling information for listing broadcast service, a content component for a broadcast service and service signaling information, the service signaling information including format information representing a payload format of an object; and a time interleaver configured to time interleave data in a PLP based on a Time Interleaving (TI) block. In addition, the TI block including data FEC blocks, and a number of the data FEC blocks is equal to a difference between a maximum value for the TI block and a number of virtual FEC blocks; and a transmitter configured to transmit the broadcast signal including the time interleaved data. Further, the signaling information is transmitted at an IP packet level, and the service signaling information is transmitted through transport packets included in the IP packets.
