Abstract
A data segment sync signal detector for an HDTV is disclosed including a segment accumulator for separating data corresponding to a segment sync signal from a composite baseband data signal by using a composite baseband data signal of the present segment to a composite baseband data signal of a previously input segment; a quantizer for comparing the output signal of the segment accumulator with predetermined threshold values so as to output level values in a predetermined number of bits, corresponding to a plurality of fixed symbol streams, that is, segment sync signal data; and a segment sync signal pattern detector for detecting the pattern of segment sync signal from the level values expressed in the predetermined number of bits output from the quantizer, thereby obtaining the phase information for respective segments and making respective segment phase pulses according to the phase information.
