Claim:
1. A method for receiving broadcast signals, the method comprising: receiving the broadcast signals; demodulating the received broadcast signals by an OFDM (Orthogonal Frequency Division Multiplex) scheme; parsing a signal frame from the demodulated broadcast signals, wherein the signal frame includes service data corresponding to each of a plurality of physical paths, wherein the service data is time interleaved data by a TI (Time Interleaving) block in each physical path; time deinterleaving the service data in the each physical path, the time deinterleaving comprising: diagonal-wise writing data corresponding to a TI block of the service data based on positions of virtual cells which are located in front of a number of FEC blocks in the TI block and the virtual cells are skipped during a reading operation of a time interleaving; and column-wise reading out the written data corresponding to the number of FEC blocks; and decoding the time deinterleaved service data.
