摘要： An apparatus for transmitting broadcast signals includes an encoder to encode service data, a mapper to map the encoded service data, and a time interleaver to interleave the mapped service data. The time interleaver includes a cell interleaver to interleave cells in a FEC block of the mapped service data, where the cell interleaver performs linearly writing the cells in the FEC block into a memory and randomly reading the cells in the FEC block according to a permutation sequence. The permutation sequence varies in every FEC block by using a shift value. The apparatus also includes a block interleaver to interleave the cell interleaved service data, where the block interleaver includes column-wise writing FEC blocks of the cell interleaved service data into a TI memory, and diagonal-wise reading the FEC blocks from the TI memory by skipping a part of cells included in the TI memory, and a convolutional interleaver to interleave the block interleaved service data.
