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 21):
A device for processing a broadcast signal, the device comprising:\n a receiver configured to receive the broadcast signal including one or more frames; a demodulator configured to demodulate 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; a frequency deinterleaver configured to perform 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 a decoder configured to decode the frequency deinterleaved broadcast signal.
