High-Definition Television (HDTV) is the new standard in technology that will noticeably change the way we watch television. For starters, the HDTV 16/9 width to height ratio is much wider than that of the standard television system's 4/3 ratio. This gives the viewer a 1/3 wider screen, closely resembling the wide screen image seen in a movie theater.
Not only is the picture wider with HDTV, it is much sharper and clearer than standard television. Composed of 1080 active lines, the HDTV picture contains 5 times more information than does the standard television picture, which uses 486 active lines. In addition, the color resolution for HDTV is more than twice that of the standard television system.
And finally, unlike the standard television system's 2-channel stereo sound, HDTV offers CD quality 5.1 channel surround sound (left, right, center, left rear, right rear, and low frequency effects).
