Abstract: A method and an apparatus for transmitting broadcast signals thereof are disclosed. The apparatus for transmitting broadcast signals comprises an encoder for encoding DP (Data Pipe) data corresponding to each of a plurality of DPs, a mapper for mapping the encoded DP data onto constellations, a time interleaver for time interleaving the mapped DP data at DP level, a frame builder for building at least one signal frame including the time interleaved DP data, a modulator for modulating data in the built at least one signal frame by an OFDM (Orthogonal Frequency Division Multiplex) scheme and a transmitter for transmitting the broadcast signals having the modulated data.

Abstract: The present invention provides a broadcast signal transmitting method. The method for transmitting a broadcast signal according to the present invention may comprise: a step of encoding data pipe (DP) data according to a code rate, the step of encoding DP data comprising a sub-step of forward error correction (FEC) encoding the DP data, a sub-step of bit-interleaving the FEC encoded DP data, and a sub-step of mapping the bit-interleaved DP data to constellation according to the code rate; a step of generating at least one signal frame by mapping the encoded DP data; and a step of modulating data of the generated signal frame by an orthogonal frequency division multiplexing (OFDM) scheme and transmitting a broadcast signal including the modulated data of the signal frame.
