Abstract
An apparatus for transmitting broadcast signals includes an encoder to encode service data corresponding to each of a plurality of physical paths; a time interleaver to time interleave the encoded service data in each physical path by a TI (Time Interleaving) block, where at least one virtual FEC block is ahead of FEC blocks in at least one TI block; a frame builder to build at least one signal frame including the time interleaved DP data; a modulator to modulate data in the built at least one signal frame by an OFDM (Orthogonal Frequency Division Multiplex) scheme; and a transmitter to transmit the broadcast signals having the modulated data.
