Word Count: 315
Summary:
You may have heard of HDTV, but the new terminology can be confusing. Let's break it down for clarity.
How HDTV is Different:
Standard analog TVs have a maximum resolution of 720 x 480 pixels, totaling about 337,000 pixels. In contrast, HDTV is part of the digital TV specifications and offers a range of video resolutions. The primary ones to focus on are 720p and 1080i. The "p" in 720p stands for progressive, while the "i" in 1080i indicates interlaced. Both deliver 60 frames per second.
- Progressive Resolution: Displays 60 complete frames each second, offering smoother motion clarity.
- Interlaced Resolution: Alternates between 30 frames of odd lines and 30 frames of even lines per second. This can sometimes result in flickering.
Resolution Details:
- 720p: Has a resolution of 1280 x 720 pixels, resulting in 921,600 total pixels.
- 1080i: Offers a resolution of 1920 x 1080 pixels, amounting to 2,073,000 pixels.
Choosing between them depends on personal preference. It's best to visit a local retailer to compare them in person.
Enhanced Sound Experience:
HDTVs often deliver better sound quality than analog TVs. Some broadcasts feature Dolby Digital 5.1 surround sound, provided you have the necessary speakers.
Buying an HDTV:
When purchasing an HDTV, note that some models include built-in tuners, while others do not. A tuner converts incoming signals into a format your TV can process. HDTVs without built-in tuners are labeled "HDTV Ready" and require an external tuner.
Viewing HDTV on a PC:
You can also watch HDTV on your computer using the ATi HDTV Wonder, which includes an antenna for airborne signals and inputs for cable and satellite connections. This setup allows you to play and record shows directly on your PC.
