Patent ID: 7218671

Claim:
An equalizer for a vestigial side-band (VSB) receiver for use in compensating distortions of a VSB broadcast signal which occurs in transmission channels using field synchronization information including synchronization information as to each field of the VSB broadcast signal and segment synchronization information including synchronization information of each data segment within the field, the equalizer comprising: an extraction unit to extract the segment synchronization information included in the VSB broadcast signal; a storage unit to store the extracted segment synchronization information; and an equalization unit to equalize the VSB broadcast signal based on the stored segment synchronization information, wherein the storage unit stores, by field unit, the extracted segment synchronization information, and the equalization unit uses the stored segment synchronization information of the field unit to equalize the VSB broadcast signal, and when the stored segment synchronization information has a same number as a number of symbols of the data segment to be received out of the entire data segment symbols within the field, the equalization unit equalizes, based on the stored segment synchronization information, the VSB broadcast signal including the data segment having the symbols corresponding to the number of symbols as the stored segment synchronization information.
