Signal Processing for Compatible HDTV
William E. Glenn, Karen G. Glenn · SMPTE Journal · 1989
High-definition television (HDTV) systems are designed to be free of many of the artifacts that appear in NTSC transmissions. HDTV and enhanced-definition television (EDTV) systems that are compatible with NTSC can also be designed to be free of these artifacts. Signal processing used to maintain constant luminance and to eliminate cross color, cross luminance, interline flicker, and objectionable line structure is discussed.
