What is HDTV?
Summary
Satellite TV providers like Dish Network offer HDTV receivers with their packages, but many people aren’t sure what HDTV really means. Here’s a clear explanation.
Understanding HDTV
Analog TV Basics
Traditional analog TVs display about 30 frames per second (25 in Europe) using a horizontal line system?"525 lines in the U.S. (625 in Europe), with roughly 500 pixels per line. This results in a resolution far lower than even the most basic computer monitors, which start at 640 x 480 pixels.
What is HDTV?
High-Definition Television (HDTV) represents a significant advancement with higher resolution than standard analog TVs. It integrates digital television (DTV) and Dolby Digital Surround Sound (AC-3). Of the 18 digital TV formats, 6 are classified as HDTV.
Progressive vs. Interlaced
The terms "progressive" and "interlaced" refer to how images are displayed:
- Interlaced: Displays odd lines first, then even lines, causing half the image to refresh every 1/60th of a second, which may lead to flickering.
- Progressive: Displays a full image every 1/60th of a second, producing a smoother picture.
Benefits of HDTV
HDTV offers a resolution of up to 2,000,000 pixels?"around ten times more detail than standard TVs. The aspect ratio of HDTV is 16:9 (widescreen), compared to the 4:3 ratio of conventional TVs.
The Future of HDTV
The FCC mandated that all U.S. TV stations must be capable of broadcasting HDTV by 2006. This directive affects broadcasters, cable companies, and consumers alike:
- Broadcasters need new equipment such as cameras and editing tools.
- Cable companies must update equipment, including home receivers.
- Consumers may need to buy new equipment, like a set-top box to convert digital signals or even a new TV.
HDTV: A Leap Forward
HDTV marks a major shift from the days of black-and-white to color and widescreen TVs, which all used the same basic signals. The transition to digital TV ended the need to accommodate older TVs, allowing remarkable improvements in picture quality.
HDTV is widely available via satellite systems like Dish Network.
