Disclosed herein is a broadcast signal receiver. A broadcast signal receiver according to an embodiment of the present invention includes a synchronization/demodulation module configured to perform signal detection and OFDM demodulation on a received broadcast signal, a frame parsing and deinterleaving module configured to parse and deinterleave the signal frame of the broadcast signal, a demapping and decoding module configured to convert the data of at least one Physical Layer Pipe (PLP) of the broadcast signal into a bit domain and to perform FEC decoding on the data, and an output processing module configured to receive the data of the at least one PLP and to output a data stream.
