    Abstract: A transmitting system, a receiving system, and a method of processing broadcast signals are disclosed. Herein, the transmitting system includes an RS frame encoder, a block processor, a group formatter, and a trellis encoding module. The RS frame encoder performs error correction encoding on an RS frame payload including mobile service data so as to form an RS frame, divides the RS frame into a plurality of portions, and outputs the divided RS frame portions. The block processor performs one of ½-rate encoding and ¼-rate encoding on each bit of the mobile service data included in each portion. The group formatter maps a portion including symbols of the ¼-rate encoded mobile service data and symbols of the ½-rate encoded mobile service data to a corresponding region of a data group. And, the trellis encoding module performs trellis encoding on the symbols of the ¼-rate encoded mobile service data and the symbols of the ½-rate encoded mobile service data of the data group.

    Abstract: A digital television (DTV) receiving system includes an information detector, a resampler, a timing recovery unit, and a carrier recovery unit. The information detector detects a known data sequence which is periodically inserted in a digital television (DTV) signal received from a DTV transmitting system. The resampler resamples the DTV signal at a predetermined resampling rate. The timing recovery unit performs timing recovery on the DTV signal by detecting a timing error from the resampled DTV signal using the detected known data sequence. The carrier recovery unit performs carrier recovery on the resampled DTV signal by estimating a frequency offset value of the resampled DTV signal using the detected known data sequence.
