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.

Abstract: A digital broadcasting system and a data processing method are disclosed. A time zone identifier is inserted into program table information of a broadcasting signal and the broadcasting signal is transmitted/received. The digital broadcasting system can calculate a local time of a region, in which the digital broadcasting system is located, using the time zone identifier. Accordingly, although the position of the digital broadcasting system is changed, it is possible to process the broadcasting signal related to the local time without an error.
