BROADCAST SIGNAL TRANSMITTING APPARATUS, BROADCAST SIGNAL RECEIVING APPARATUS, AND METHOD FOR TRANSCEIVING A BROADCAST SIGNAL IN A BROADCAST SIGNAL TRANSCEIVING APPARATUS

摘要

Disclosed are a broadcast signal transmitting apparatus, a broadcast signal receiving apparatus, and a method for transceiving a broadcast signal in a broadcast signal transceiving apparatus. A method for transmitting a broadcast signal comprises the following steps: performing FEC encoding on an input signal; dividing the FEC-encoded signal into a first input signal and a second input signal in accordance with a modulation type; performing MIMO encoding on the first input signal and the second input signal to output a first transmission signal and a second transmission signal; inserting a pilot signal of a pilot pattern determined on the basis of FFT size information into a first signal frame containing the first transmission signal, and inserting first and second preamble signals into a starting point of the first signal frame to which the pilot signal is inserted; and inserting a pilot signal of a pilot pattern determined on the basis of FFT size information into a second signal frame containing the second transmission signal, and inserting first and second preamble signals into a starting point of the second signal frame to which the pilot signal is inserted.
