BROADCAST SIGNAL TRANSMITTING DEVICE, BROADCAST SIGNAL RECEIVING DEVICE, BROADCAST SIGNAL TRANSMITTING METHOD, AND BROADCAST SIGNAL RECEIVING METHOD

摘要

A broadcast signal transmitting device according to an embodiment of the present invention may comprise: an encoder for encoding service data; a framing block for generating at least one signal frame including the encoded service data; a frequency interleaver for frequency interleaving data in at least one signal frame by using an interleaving sequence generated on the basis of a basic interleaving sequence and a symbol offset value; a modulator for modulating the frequency interleaved data by using an OFDM (Orthogonal Frequency Division Multiplex) technique; and a transmitting unit for transmitting broadcast signals including the modulated data.
