    摘要: 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.

    摘要: A method for transmitting a broadcast signal in a digital transmitter, includes generating transport packets of transport streams including service data; generating link layer packet including the transport packets; the link layer packet including a base header including configuration information indicating a configuration of a payload of the link layer packet, the link layer packet further including an additional header including information for segmentation or concatenation based on the configuration of the payload, and the additional header further including information representing that an optional header for a sub-stream identification identifier is present after the additional header, the link layer packet further including an optional header having the sub-stream identification identifier; generating signaling information including link mapping information between the sub-stream identifier and an IP address and an UDP port carrying a transport stream for the sub-stream identifier; generating a broadcast signal including the link layer packet and the signaling information; and transmitting the broadcast signal.
