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 input data; performing symbol mapping on the FEC-encoded data; locating the symbol-mapped data to the relevant positions in a signal frame to constitute the signal frame; and inserting a pilot signal into the signal frame, and inserting first and second preamble data into a starting point of the signal frame to which the pilot signal is inserted.
