Abstract
A method for transmitting broadcast signals, the method includes encoding service data; parity interleaving parity bits of the encoded service data; group-wise interleaving bit groups included in the parity interleaved service data according to a permutation order; block interleaving the group-wise interleaved bit groups with a set including a number of bit groups, wherein the number of bit groups included in the set corresponds to a modulation order, wherein the block interleaving includes row-wise writing bits of the group-wise interleaved bit groups in the set; and column-wise reading 1 bit from each row of the set; building at least one signal frame including the block interleaved service data; modulating data in the built at least one signal frame by an OFDM (Orthogonal Frequency Division Multiplex) scheme; and transmitting the broadcast signals having the modulated data.
