摘要： A broadcast signal transmission method includes generating, by a packetizer, a first transport packet carrying one or more fragments of a delivery object and a second transport packet carrying signaling data based on an ALC/LCT scheme. In addition, a header of the first transport packet includes offset information representing a starting byte position of a fragment of the delivery object included in the first transport packet, the header of the first transport packet includes Transport Object Identifier (TOI) information that is mapped to Uniform Resource Locator (URL) information for the delivery object described in the signaling data, the signaling data includes a real-time attribute representing whether the delivery object transmits a real-time content, and content type information presenting a type of a content; processing one or more IP packets including the first transport packet and the second transport packet to generate a broadcast signal, the processing includes encoding data in the one or more IP packets to output data of one or more Data Pipes, and interleaving data of a Data Pipe by a Time Interleaving (TI) block based on one or more virtual Forward Error Correction (FEC) blocks, frequency interleaving the interleaved data of the Data pipe; and transmitting, by a transmitter, the broadcast signal. Further, the signaling data is delivered in a transmission session separate from the delivery object.
