The international standard for High Definition Television (HDTV) in MPEG- 2 has been established for a few years. 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. Based on them, the authors draw their spectral figures.
