A. HDTV is no longer just a mirage, shimmering on the horizon. Lots of people are already enjoying its crystal-clear picture and sound. And once you’ve seen HDTV’s sharp detail, lifelike depth and vivid colors, you’ll also be amazed. HDTV owners swear that high-definition viewing is like looking through a window.

A High Definition Television (HDTV) is a type of Digital Television (DTV) that receives and/or displays high definition television images and surround sound. HDTV programming and TVs together provide a detailed, sharper image due to the increased number of pixels contained in the received digital. HDTV screens are wider than the traditional analog TV screens. Analog TVs offer a screen aspect ratio of 4:3 while HDTVs offer an aspect ratio of 16:9, which is similar to a movie screen. This allows you to see movies as they were filmed without reformatting. There are also HDTV capable sets that have the regular TV 4:3 ratio, but format HD content in a letterbox presentation (with black bars on the top and bottom of the TV image). Enhanced Definition Televisions (EDTV) also exists. These 4:3 aspect ratio TVs can not receive HD formatted signals. They can receive enhanced definition signals, which do not have the detail of an HD signal, but do improve on the standard definition (SD) picture.

High-Definition Television (HDTV) is a type of Digital Television (DTV) that receives and/or displays high-definition images and typically Dolby® Digital 5.1 Channel surround sound. HDTV programming and HDTVs together provide an image that is five-times sharper than a standard TV due to the increased number of pixels contained in the received signal. HDTV screens are wider than the traditional analog TV screens. Analog TVs offer a screen aspect ratio of 4:3 while HDTVs offer an aspect ratio of 16:9, which is similar to a movie screen. This allows you to see movies as they were filmed without reformatting. There are also HDTV-capable sets that have the regular TV 4:3 ratio but format HD content in a letterbox presentation (with black bars on the top and bottom of the TV image). Enhanced–Definition Televisions (EDTV) also exist. These 4:3 aspect ratio TVs cannot receive HD-formatted signals. They can receive enhanced-definition signals, which do not have the detail of an HD signal but do

(Last updated: 02/17/2002) Back to top HDTV is a set of video quality standards which include resolutions far better than normal NTSC or PAL TV. The most common resolutions discussed are 1080i (1080 horizontal lines of resolution) and 720p (720 lines). The ‘i’ stands for interlaced and the ‘p’ stands for progressive. Standard NTSC signals (regular TV) have 525 lines of resolution, of which only 480-483 are visible. NTSC video is commonly called ‘480i’.

A ‘scan line’ is a single left-to-right line made by the beam. In a standard NTSC signal, for example, there are 525 scan lines (you can only see about 480 of them). Int
