BROADCAST SIGNAL TRANSMISSION DEVICE, BROADCAST SIGNAL RECEPTION DEVICE, BROADCAST SIGNAL TRANSMISSION METHOD, AND BROADCAST SIGNAL RECEPTION METHOD

摘要

The broadcast signal transmission device according to one embodiment of the present invention may comprise: an encoder for encoding service data; a framing block for mapping the encoded service data to data symbols so as to generate one or more signal frames; a frequency interleaver for frequency-interleaving data in the one or more signal frames by using an interleaving sequence; a modulator for modulating the frequency-interleaved data by means of orthogonal frequency division multiplexing (OFDM); and a transmission unit for transmitting broadcast signals comprising the modulated data.
