Some industrialized modern countries are positively developing HDTV products. However, there are few profound analyses of the HDTV luminance signal's three dimensional (3 D ) spectrum. The authors make a detailed study of them and sum up the features of the (3 D ) HDTV luminance signal's spectrums and their mathematical expressions.
