How Hdtv Is Taking Over The Entertainment Industry

It's been around for a while, but only recently has it made a huge difference. The question, of course, is "why". What is HDTV technology and how is it so different that it's become so much more important these days than ever before by it's predecessors? Here are some highlighted points of interest.

High-Definition is a broad term because it just means better quality, which could mean anything. The term high-definition used to refer to TVs back in 1934, because they were very high-definition when compared to their earlier models. What HD really means is higher resolution, and HD nowadays means a lot higher. The traditional pixel resolution for HD is 800,000 or more, which far surpasses the 1934 HD's 30 pixel resolution.

Blu-ray has opened up the use of HD like never before. In the past, HD affected what you watched by a marginal, albeit noticeable, amount. The images may have been a little clearer, but nothing compared to what Blu-ray has opened us up to. The catch, of course, is not only that you have to have a Blu-ray player, but that you have to have HDMi connections on your TV to use it.

This is what makes HD so important now, because not only is the quality of the TV improved, but the quality of the video itself is improved. It's not just Blu-Ray, either. Some TV channels are in HD, as well as some other DVDs. They all use their own compressed pixel ratio that can only be seen with HD technology, because a less advanced TV can't utilize that amount of information. The intensity of the picture quality is certainly far greater by comparison than past models.

It's all part of why HD means so much more in the present than it has in the past: technological advancement. To truly utilize full HD potential, using an HDMi (or high-definition multimedia interface) port is essential. Things that claim to have exceptional HD quality require it because you cant translate that much data any other way. There are several things that use HDMi connections, and each on stands for incredible quality.

The other important aspect of HD is how the information is scanned. Most TVs are 1080i or 1080p, where the 1080 means 1,080 lines of resolution. More lines of resolution means a better quality video because, much like pixels, if there are more lines, then the image is tighter. That way, the actual make up of the image cannot be seen as easily (which is a good thing).

The difference shows up between the "p" and the "i". The "p" means progressive scanning, meaning that all 1,080 lines are displayed in sequence, providing a higher quality image. The "i" means interlaced scanning, meaning that 540 of the lines are scanned alternatively (the 540 even lines followed by the remaining 540 odd lines), to help reduce bandwidth consumption. Progressive scanning, of course, is a much crisper image display, and doesn't have a "twittering" image that interlaced scan has, but in return, it uses more bandwidth.

There's no question that an HDTV is a better quality machine, but it's only better depending on how you use it. The technology of the TV is only as strong as it's weakest link. Not having the TV, for instance, is the same as having the TV and not having the connection. Overall, though, it's home theater brought to a new, and better, age.
