Patent Images
1. A method of receiving a broadcast signal comprising:
- orthogonal frequency division multiplexing (OFDM) demodulating a received broadcast signal;
parsing a signal frame of the received broadcast signal;
time deinterleaving broadcast data of the signal frame;
forward error correction (FEC) decoding the broadcast data; and
formatting the broadcast data and outputting a data stream,wherein the time deinterleaving broadcast data includes block deinterleaving data cells included in the broadcast data in a unit of a time interleaving (TI) block.
