Abstract:
A method and an apparatus for transmitting broadcast signals thereof are disclosed. The apparatus for transmitting broadcast signals comprises an encoder for encoding service data, a mapper for mapping the encoded service data into a plurality of OFDM (Orthogonal Frequency Division Multiplex) symbols to build at least one signal frame, a frequency interleaver for frequency interleaving data in the at least one signal frame by using a different interleaving-seed which is used for every OFDM symbol pair comprised of two sequential OFDM symbols, a modulator for modulating the frequency interleaved data by an OFDM scheme and a transmitter for transmitting the broadcast signals having the modulated data, wherein the different interleaving-seed is generated based on a cyclic shifting value and wherein an interleaving seed is variable based on an FFT size of the modulating.

Claim (Index 24):
A method for processing a broadcast signal, the device comprising:\n receiving the broadcast signal including one or more frames; demodulating the broadcast signal by an Orthogonal Frequency Division Multiplexing (OFDM) scheme based on one or more Fast Fourier Transform (FFT) modes for the one or more frames; performing frequency deinterleaving operation, that is applied to each signal frame of the demodulated broadcast signal, using a deinterleaving sequence,\n wherein in response to a frame that is demodulated based on a 32K FFT mode, a first deinterleaving sequence is used, \n the first deinterealving sequence is generated by generating a second deinterleaving sequence based on a main sequence and a symbol offset, and checking a validity of one or more addresses of the second deinterleaving sequence, and \n a value of the symbol offset is constant for a pair of two consecutive symbols in the signal frame; and \n decoding the frequency deinterleaved broadcast signal.
