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

摘要

The broadcast signal reception device according to one embodiment of the present invention may comprise: a reception unit for receiving broadcast signals; a demodulator for demodulating the received broadcast signals by orthogonal frequency division multiplexing (OFDM); a time deinterleaver, which is a signal frame parser for parsing one or more signal frames from the demodulated broadcast signals, wherein the one or more signal frames comprise service data corresponding to a plurality of physical paths, the time deinterleaver time-deinterleaving the service data by time interleaving (TI) block unit; and a decoder for decoding the time-deinterleaved service data.
