If you're like many people today who have purchased a new large flat-screen HDTV and love the clear, crisp picture, you're probably wondering, what is high definition television anyway? HDTV is the latest, best thing to happen to tv technology since the invention of colorized TV. HDTV offers a better quality picture with richer detail than its older counterpart. The picture is also wider and compared to regular televisions, HDTV offers luminance definition horizontally and vertically. These televisions offer more of what is seen at a movie theater.
The one thing that makes it stand apart from conventional television is the picture quality. Standard TV's have almost imperceptible lines running through the picture, but can be noticed if you look closely. These are called active lines and regular televisions have 486 of them. HDTV's have over twice as many active lines, but even if you looking closely, you will not see them. This fine-grain high definition picture also receive much more image information compared to standard TV's. Not only is the picture excellent, but the sound quality is also superb.
For a person to really understand what is high definition television, knowing the basics of resolution helps. Standard televisions all contain 480i or 480p resolution or visible scan lines, which according to the kind of TV it is, these lines are either scanned progressively (p) or they are interlaced (i), which provides the picture we see. HDTV's are either 720p, 1080i or 1080p. High definition televisions have a standard of 720p, or lines of scanned progressive resolution. This provides a smoother, movie-like image with a sharper, cleaner picture. The most common HDTV format is 1080i resolution, which provides a more detailed picture than does the 720p. Smaller screened televisions really do not benefit from 1080 resolution.
Digital televisions that are capable of displaying television signals in HDTV of 720p, 1080i or1080p are called HDTV capable. Digital TV's that are HDTV capable and have a HDTV receiver built in to them are called "integrated". HDTV's that are capable of displaying high definition resolution but do not have a receiver are called HDTV capable monitors. For those who know little to nothing about what really makes HDTV so superb, just viewing the picture is enough to prove the obvious advantage of upgrading to a high definition television.
