Broadcast signal transmitting apparatus, broadcast signal receiving apparatus, broadcast signal transmitting method, and broadcast signal receiving method

摘要

Disclosed herein is a method of receiving a broadcast signal. The method comprises receiving the broadcast signal; an Orthogonal Frequency Division Multiplexing (OFDM) demodulating on the received broadcast signal; parsing at least one signal frame from the demodulated broadcast signal to extract service data or service component data; converting the service data or service component data into bits; decoding the converted bits; and outputting a data stream comprising the decoded bits.

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.
