5. A reception apparatus for processing a broadcast signal, the reception apparatus comprising:
a receiver configured to receive the broadcast signal including broadcast data and physical layer signaling information, wherein the physical layer signaling information includes frequency interleaver information for indicating whether a frequency interleaver is applied to the broadcast data;
a frequency deinterleaver configured to perform frequency deinterleaving on the broadcast data selectively based on the frequency interleaver information, wherein the frequency deinterleaving is performed on the broadcast data in response to the frequency interleaver information having a first value and wherein the frequency deinterleaving is not performed on the broadcast data in response to the frequency interleaver information having a second value;
a convolutional deinterleaver configured to perform convolutionally deinterleaving on the broadcast data which the frequency deinterleaving is performed or not performed;
a block deinterleaver configured to perform block deinterleaving on the convolutionally deinterleaved broadcast data;
a cell deinterleaver configured to perform cell deinterleaving on the block deinterleaved broadcast data using a memory, wherein the cell deinterleaving includes random writing the block deinterleaved broadcast data into the memory and linear reading the block deinterleaved broadcast data from the memory, and wherein the random writing is performed based on a permutation sequence and the permutation sequence varies for every Forward Error Correction (FEC) block; and
an FEC decoder configured to FEC decode the cell deinterleaved broadcast data.
