Broadcasting signal transmission device, broadcasting signal reception device, and method for transmitting/receiving broadcasting signal using same
Disclosed is a broadcasting signal transmission device, a broadcasting signal reception device, and a method for transmitting/receiving a broadcasting signal using same. The method for receiving the broadcasting signal comprises the following steps: receiving the broadcasting signal, which includes a transmission frame, wherein the transmission frame includes a plurality of PLPs, which transmit components that constitute a broadcasting service, first signaling information and second signaling information, which include the signaling information of the plurality of PLPs, a first preamble signal, which has been signaled with a preamble format, and a second preamble signal, which has been signaled with pilot pattern information, wherein one of the plurality of PLPs is a base PLP, which includes a program number that corresponds to the broadcasting service and program map table information, which has been signaled with identifying information for each of the PLPs; demodulating the broadcasting signal based on the first and the second preamble signals; FEC decoding the demodulated broadcasting signal; and identifying a PLP group that includes the plurality of PLP from the FEC decoded broadcasting signal based on the first and the second signaling information, decoding at least one PLP of the identified PLP group, and providing the broadcasting service.

Forward Error Correction (FEC) encoding Physical Layer Pipe (PLP) data of a plurality of PLPs;
first interleaving the FEC-encoded PLP data;
second interleaving the first-interleaved PLP data;
FEC encoding signaling data for signaling the PLP data; and
modulating a signal frame including the second-interleaved PLP data and the FEC-encoded signaling data,
wherein the signaling data includes identification information for identifying each PLP, and
wherein preamble symbols are located at the beginning of the signal frame in a time domain after modulating the signal frame.
