What is HDTV?
Webmasters: You may reprint this article in its entirety, providing you leave the Byline and About the Author sections intact, including the links to Dish Network Satellite TV. High Definition TeleVision is what HDTV literally means. But high definition compared to what? In order to answer this question, we need to know a bit about the original analog TV system. Analog TV 30 images per second (in Europe 25) are shown by normal analog TV sets. It does this by writing image lines horizontally, 525 lines in one image (In Europe 625) on the screen. The number of pixels on one line is about 500. This would be a definition of 500 pixels per line by 525 (or 625) lines. Compared to modern computer monitors this is really bad. Even the lowest resolutions monitors have higher resolutions (640 x 480) than an analog TV. HDTV - High Definition TeleVision HDTV is high resolution Digital TeleVision (DTV) combined with Dolby Digital Surround Sound (AC-3). There are 18 different formats defined for Digital TV of which 6 are considered to be HDTV: Active Lines Per Picture Pixels Per Line Aspect Ratio Frame Rate Scanning Approach Other HDTV Items of Interest: The path of United States HDTV world 1080p HDTV Confused by the difference between EDTV and HDTV EDTV vs HDTV High Definition Television Who Has The Lead In The Satellite TV Market Choose The Right HDTV Antenna For Your Set Up How Hollywood is trying to control your HDTV Which is better EDTV or HDTV LCD vs Plasma HDTV 50 Inch Daewoo Plasma HDTV Reviewed HDMI Guide To HDTV Connection Of The Future The Difference between EDTV and HDTV Should Your Next Big Screen TV be a Plasma HDTV The HDTV Market Follows the Same Route as the Personal Computers HDTV You ain t seen NOTHING yet 1080p HDTV Sets have started to emerge Should you opt for one HDTV HDTV and the iPod photo A Perfect Marriage Choosing the right HDTV antenna for you How to Avoid the HDTV Resolution Trap |
