HDTV is an acronym
for High Definition Television, which is Digital TV in its
highest and best form. The current NTSC television signal
is made up of 525 lines that are scanned horizontally with
480 lines being dedicated to the actual picture information.
HDTV pictures are created by scanning 1,125 lines with 1080
lines of picture. Adding twice the lines multiplies the amount
of pixels (the small dots that create a clearer and more detailed
picture). The screens of the older analog sets contained about
300,000 pixels, while the wider HDTV screen is composed of
more than 2 million pixels. The movie theater-like format
(16x9 versus 4x3 like on today's sets) and separate surround
sound channels more closely resemble your vision and hearing,
thus drawing you deeper into the experience and enhancing
your viewing pleasure. The pictures are clearer, crisper and
more detailed, involving the viewer in an almost three-dimensional
feeling.
