HDTV; High definition television is the broadcasting of television stations with a higher resolution and higher quality of picture. Hi-def television has about twice the quality of resolution as a normal television, which allows more detail to be seen in the picture. High definition television is broadcasted in widescreen and digitally, enhancing the picture even more. This causes the colors on the picture to looks more realistic and detailed, while providing more clarity and specificity even on a large screen.

A 480i television is strictly a digital television with no high definition features. A 720i television is the low end of HDTV, while 1080i resolution denotes a primarily high definition television.
