Abstract
A method and an apparatus for receiving broadcast signals thereof are disclosed. The apparatus for receiving broadcast signals, the apparatus comprises a receiver to receive the broadcast signals, a demodulator to demodulate the received broadcast signals by an OFDM (Orthogonal Frequency Division Multiplex) scheme, a frame parser to parse a signal frame from the demodulated broadcast signals, wherein the signal frame includes service data corresponding to each of a plurality of physical paths, a time deinterleaver to time deinterleave service data in each physical path by a TI (Time Interleaving) block, wherein the time deinterleaver further performs inserting at least one virtual FEC block into at least one TI block of the service data, wherein each TI block includes a variable number of FEC blocks of the service data, wherein a number of the at least one virtual FEC block is defined based on a maximum number of FEC blocks of a TI block and a decoder to decode the time deinterleaved service data.
