Claim:
1. A reception apparatus for receiving a broadcast signal, comprising: a receiver configured to receive the broadcast signal including a signal frame, wherein the signal frame includes preamble, wherein the preamble includes control information indicating whether a frequency interleaving is enabled or not; a demodulator configured to demodulate the received broadcast signal by Orthogonal Frequency Division Multiplexing (OFDM) scheme; a frequency deinterleaver configured to selectively perform frequency deinterleaving on data in the signal frame based on the control information; a de-mapper configured to de-map Physical Layer Pipe (PLP) data in the signal frame; a bit deinterleaver configured to bit-deinterleave the PLP data; a Forward Error Correction (FEC) decoder configured to FEC-decode the PLP data; and an output processor configured to output a data stream, wherein when the control information has a first value, the frequency deinterleaver is enabled and when the control information has a second value, the frequency deinterleaver is disabled.
