Claim:
1. A method of receiving a broadcast signal, the method comprising: receiving the broadcast signal, wherein the broadcast signal includes at least one signal frame, the signal frame includes control information indicating whether a frequency interleaving (FI) is used for a specific transport block in the signal frame; demodulating the broadcast signal using an Orthogonal Frequency Division Multiplexing (OFDM) scheme; obtaining the control information in the broadcast signal; selectively frequency deinterleaving the specific transport block based on the control information; de-mapping service data of the specific transport block into bit domain; Forward Error Correction (FEC) decoding the service data; and outputting data stream including the service data, wherein whether or not to perform the frequency deinterleaving for the specific transport block is determined based on the control information.
