The Technology of High Definition: The Top-of-the-Line in Viewing Experience



One can witness quite a rapid rate of advancement in the industry of home entertainment today. The public is introduced to new technologies each year, and models are becoming obsolete at a faster rate. High definition or HD oem software technology is emerging as the preferred format for almost any kind of TV or DVD viewing in news, reality shows, documentaries, soaps, and especially movies and sports. There has been a rapid increase in the demand for products with HD technology, mostly due to the media frenzy with regards to it, as well as the government's requirement that all broadcasts be made with digital technology.

What is High Definition or HD? What are the advantages that it has and why should we want it? HD is a type of digital media that offers its viewers with an excellent quality image and resolution. Images being produced by products with HD technology are crisp and crystal clear, like the images that the eye sees or pictures which appear as clearly as in movie theaters.

High definition technology looks a lot clearer than SD or standard definition due to the composition of an image that is higher in resolution. An image on the screen is composed of pixels, or a series of small dots. In a single picture frame, there are a series of horizontal lines of pixels called scan lines. You can get HD discount software technology from several suppliers. The amount of such scan lines determines the resolution of the images. In an HD image, one frame has 1080 scan lines that are interlaced, or it has 720 scan lines that are progressive. In contrast, there are only 525 lines in an SD frame. That gives HD a far superior image quality and detail.

In addition to this more extensive detail, HD also provides a more life-like picture due to the fact that its images are shown in a widescreen aspect ratio of 16:9. This is a rectangular ratio, in contrast to the square 4:3 aspect ratio of a standard definition image.

What advantage does this give? Many feature-length movies are actually shot in the rectangular aspect ratio of 16:9. Thus, viewing the same movie in a screen with a similar aspect ratio guarantees better image quality since one sees the image exactly as it was shot.

When stored in DVD media, like cheap windows 7, the increased detail of HD means more storage space is needed. A thirty-gigabyte HD DVD can only store up to eight hours of 1,125 HD scan lines, while the same space can contain up to forty eight hours of 525 SD scan lines. This means that there is a lot more detail that is stored. It then produces crystal clear pictures, which capture even the smallest details, resulting in an unsurpassed viewing experience. HD is hyped up as the ultimate in visual entertainment.
