Abstract
A method of transmitting a broadcast signal includes encoding data which is carried by Data Pipes (DPS); mapping the encoded data to constellations; interleaving the mapped data by skipping virtual cells based on a memory address for the interleaving; building at least one signal frame having symbols including the interleaved data; frequency interleaving cells of the symbols in the at least one signal frame; modulating the at least one signal frame including the frequency interleaved cells of the symbols by an orthogonal frequency division multiplexing (OFDM) scheme; and transmitting the broadcast signal including the modulated at least one signal frame.
