Resolution (it's math...that works for you)
The crisp, _iGlikepicture that peopD raveaboutwhen experiencingtrue HDTV is due to the resolution this
technoh)5_, provides. The resoh_fion is measured by calcuh@_g the number of active lines of pixds. A pixd
(which stands f{)rpicture demen0 is a small dot. The picture you see on your TV is composed of these dots.
A reguhr, analog teDvision only has a resoh(flon of about 200,000 pixds (480 vcrtical pixds x 440
horizontal pixds = 21 !,200 pixds). The HDTV format is capable of more than 2 million pixds (1,920 x
1,080 = 2,073,600).
More pixds equal more detail. In summary, HDTV is capable of resolution that is up to 10 ti*_lesthe
resolution of the picture on a regular, anah)g TV!

Aspect Ratio
Aspect ratio i5 sin]ply the width and height o_ the picture. Regular TX's
use a 4:3 aspect ratio, which means the picture is a little wider than it is
tall (a screen that is 20 inches wide is about 15 inches tall).
When the standards were being developed tier television broadcasting
in 1941 by the NTSC (the National Television Standards Committee), it
made sense to adopt the 4:3 aspect ratio that the film industry was
using at that time.
As TV5 dropped in price and people pro:spered in the 1950s, the movie
industry had to find a way to get people ()tit (£ their livi_-,grooms and
back to lhe movie theatres. That's when they created/he 1(5:9 aspect
ratio (atso called wi(tescreen _ormat). When the standards tor HDTV
were being developed by the ATSC (Advanced T(qevision Standards
Conrmittee), the 1(5:9aspect ratio was chosen as the _ormat tor HDTV.
This wi(tescteen format makes sense because it's much closer to the
way \re see. Our fiekt ot vision is actually much wider than tall
because ot our peripheral vision. Not only is it closer to the way we
see, but the pictures are crisper and cleaner with more detail in the
close-up and panoramic views.
