High-definition television is a high-resolution digital widescreen TV format. A high-definition TV signal has twice the color resolution and imparts a picture that is six times sharper than that provided by a traditional analog TV set. HDTV likewise provides enhanced audio, such as Dolby Digital. An image displayed on a TV screen is comprised of small, adjacent rectangles known as “pixels.” TV resolution refers to the number of horizontal lines (comprised of pixels) that are displayed on the TV screen. Traditional analog TV sets have 480 horizontal lines. On the other hand, high-definition TVs have 720 horizontal lines or more. High-definition television also differs from standard analog television in pixel size. The pixels in analog TV sets are slightly taller than their width (which is why distortion is sometimes seen on these sets). Conversely, the pixels in high-definition TV screens are square, smaller and spaced more closely together. Finally, high-definition TVs employ a 16:9 aspect ratio (i.e., wide-screen format), rather than the 4:3 aspect ratio utilized by traditional analog TV sets. However, there are some HDTV’s, which only have a 4:3 screen. Even though high definition television comes in widescreen format, not all widescreen broadcast is high definition. DVD’s, for example, can sometimes display in widescreen but the content is not necessarily high definition.
