4H DIGITAL COMB FILTER
Accurately separates color data (chroma, or C) from black and white data (lumina, or Y) to produce improved color images and picture quality.
EDTV
Uses progressive scan technology to display noticeably higher quality images than the conventional “interlacing” method.
DIGITAL PROGRESSIVE SCAN
Lines of video data are processed faster and sequentially, a significant improvement on the old
“interlacing” method. This allows the TV to display crisp, clear images when receiving data from a DVD player or other video sources requiring more bandwidth.
NTSC TUNER
Accepts standard United States broadcast video signals as designated by the National Television
Standards Committee.
HI-RES COMPONENT VIDEO
Delivers the highest quality picture by breaking down video data into three separate signals—red, blue and luminance—before the data is sent to the television.
