An apparatus for generating a sync signal of a data segment in a high definition television is disclosed including: means (41) for delaying and integrating received data segment signals in the period of the segment; means (42) for delaying the output of the integration means in the period of sync signals, multiplying the delayed sync signals by a correlation value of a corresponding sync signal, and summing the multiplied sync signals, to thereby detect a sync signal having its peak for the period of the sync signal; and means (43) having a predetermined reference value and for comparing the output of the sync detecting means with the reference value, to thereby generate the sync signal of data segment. This apparatus is capable of accurately generating segment sync signals in any environment of transmission channel in an HDTV.
