<h1>How HD Technology Works and Why It's much Better than Standard</h1><strong> Author: <a href='http://www.articleseen.com/profile_mitchell crew.aspx'>mitchell crew</a></strong><br /><p>When television service first began, it was an analog-only setup. In time, the public saw the birth of digital signal. Until recently, there was a mix of the two mediums providing TV service. Now, analog signal has run its course and digital signal is the exclusive engine of modern television. Due to its compact nature, digital signal ushers in a wider mix of channels, enhanced audio and picture quality like HD technology. Digital satellite and cable also offer more reliable service. This is largely the result of digital code consisting of ones and zeros. This allows the signal to travel longer distances. It also makes them nearly impervious to the effects of harsh weather. In the present time of all-digital TV, you’ll see two signal modes: high-def and standard. Either way, you’re in step for improved quality. So, how do SDTV and HDTV compare side to side. It’s hardly a stretch that you know HDTVs provide superior picture resolution, but how? Well, it’s largely due to the high number of lines spanning the width of a TV set. That number can reach 1080 on a top-level HD, whereas SDTV lines top out at 480. HDTVs also lay home to more pixels, pixels that also come arranged in close proximity. For the home viewer, this means a picture alive with richer and more realistic color detail and hues. Additional dissimilarities come into view when you examine aspect ratios. On an HDTV, the aspect ratio measures a typical 16:9. You may have noticed that HD television sets typically run wider than they do long. The aforementioned A.R. is the reason why HD sets do so. It’s also the standard seen on today’s modern Cineplex screen. As such, the home entertainment enthusiast can tune into full-view screening of DVDs and Blu-Ray films. This enjoyment is lost on SDTVs. Their aspect ratio equals 4:3, which means viewing a screen that’s nearly square in dimension. Ultimately, this leads to a diminished viewing spectrum. The perks of HDTV viewing are many. Still, some may hesitate to purchase an HD set out of concern for the price. On that note, know that HDTVs have dropped substantially in cost since they were unleashed on the market in 2002. Viewing channels in HD does cost extra on top of any core programming plan you choose. However, the monthly fee for HD service is unlikely to exceed $10 a month. If you like the idea of HD technology, it’s an affordable commodity that offers a lot.</p><strong>About the Author:</strong><br />Learn more about <a rel="nofollow" href="http://www.bundledservice.com/Default.aspx">HD technology</a> and <a rel="nofollow" href="http://www.bundledservice.com/Default.aspx">HD service</a> and see which TV providers offer the highest number of <a rel="nofollow" href="http://www.bundledservice.com/Default.aspx">channels in HD</a>.<p> Article Source: <a href='http://www.articleseen.com/Article_How-HD-Technology-Works-and-Why-Its-much-Better-than-Standard_15763.aspx'> http://www.articleseen.com/Article_How HD Technology Works and Why It's much Better than Standard_15763.aspx</a></p>
