A broadcast signal reception method, according to one embodiment of the present invention, may comprise the steps of: receiving a broadcast signal, demodulating the received broadcast signal by an orthogonal frequency-division multiplexing (OFDM) method, parsing at least one signal frame from the demodulated broadcast signal, convolutionally deinterleaving data in the at least one parsed signal frame, block deinterleaving the convolutionally deinterleaved data, cell deinterleaving the block deinterleaved data, and decoding the cell deinterleaved data.
