APPARATUS FOR TRANSMITTING BROADCAST SIGNALS, APPARATUS FOR RECEIVING BROADCAST SIGNALS, METHOD FOR TRANSMITTING BROADCAST SIGNALS AND METHOD FOR RECEIVING BROADCAST SIGNALS |
摘要 |
A method and an apparatus for transmitting broadcast signals thereof are disclosed. The apparatus for transmitting broadcast signals comprises an encoder encoding service data, a time interleaver interleaving the encoded service data, a mapper mapping the interleaved service data into a plurality of OFDM (Orthogonal Frequency Division Multiplex) symbols to build at least one signal frame, a frequency interleaver 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, wherein the frequency interleaving is performed by using two memories, a modulator modulating the frequency interleaved data by an OFDM scheme and a transmitter transmitting the broadcast signals having the modulated data, wherein an interleaving-seed is generated based on a cyclic shift value and an FFT size of the modulating. |
