This paper shows several techniques to improve the performance of the correlation processing in decoding EDTV-II signal. EDTV-II system controls the amplitude of VT/VH signal according to the correlation between main panel signal and VT/VH signal. The conventional correlation detection does not always work correctly when the horizontal edge moves horizontally. The wrong detection increases the noise.
