You've probably heard about it, and you're probably wondering about how it all works. It's advertised everywhere, and everyone is trying to get you to buy one. With Blu-Ray out now, it's even more critically acclaimed. Here are some things that should help inform you about HDTV technology.
Firs off, what does HD even mean anyway? It means high-definition, but that doesn't describe much either, because high-definition just means better quality, and that's pretty vague. The first TV to be considered HD was back in 1934, and it was considered high-definition because it boasted a 30 pixel resolution. While that's a joke now, it was a big deal back then. Nowadays, the common high-definition TV has a pixel resolution of 800,00 or more.
What makes HD so much more important these days than it has been in the past is the invention of things such Blu-Ray. A TV with better quality was certainly a great thing, but what is even better is another type of technology that assists in this higher technology. Blu-Ray puts out a substantially higher quality video, but the catch is you can only use it with an HDMi connection, meaning it needs to be HD.
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.
This quality comes from the output video, but more importantly from the TV as well. This is because the modern TV is generally 1080i or 1080p. The 1080 part means how many pixels of resolution. An image broken up into these lines is much clearer when there's more lines to hide the separation, which is why a bigger number 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.
All that's mentioned here are just a few reasons why HDTV technology is so much greater than ever before. It all comes down to technological advancement, which means all HD products need to be used together to really get what everyone is raving about. And that is all why HD really makes a difference.
