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.
