HDTV – The most important tips and advice
ByExplained briefly what it is and what it takes!
Technically inclined to forgive us that we respond to every little detail here. It should be a simple introduction to the topic
HDTV means “High-definition Television” which means to be means high-definition television. No word has been in recent years, more technology and home theater enthusiasts dream of friends worldwide.
To properly understand HDTV to be first, some basic things.
Do not have an HDTV?
Then watch TV and movies from DVD / VHS, etc. In classical PAL system. For some time, but we also hear more and more often the term “SDTV”.
SDTV is “Standard Definition Television” are technically the 768 x 576 pixel resolution at 50hz frame rate.
SDTV and Pal system is thus the same!
In the simplest sense HDTV is nothing more than a higher resolution image data. But this brings some problems.
Can I watch my HDTV with a standard television? No to play it, you need a TV / projector with higher resolution and special connections!
This is due to the higher resolution. Thus are technically much higher Anforderrungen to the transmission as the already very elderly SDTV system.
There are two resolutions that are important for HDTV, that would even the maximum resolution of 1920×1080 pixels and the “small” format with 1280×720 pixels. You’ll see the “numbers”, the HDTV has a much higher resolution than SDTV has (768×576 pixels)
When HDTV makes sense?
You have to honestly say that HDTV makes only from a certain size this much fun and of course the proper viewing distance! We recommend that for a projection HDTV with a minimum of 2m width and LCD TV and Plasma TV, it should already be 42ZOLL and more. They will question why is that? It is simply a lack of resolution.
A comparison. Modern digital cameras have already far more resolution than HDTV images. Take a photo with an 8 megapixel camera and the same design with a 1 megapixel camera. Now do the camera in a classic postcard-size prints. Laid side by side, you can not distinguish the two photos. The image size is sufficient for the fine details of 8M camera simply is not enough. Make poster-size prints, but the image of the camera, the 1M-8M camera turns lengths. Simply put, you need space to display a high resolution to be able to.
Reviews for the selection of units:
The industry has made because it is quite simple, you just invented a new logo and slogan. It’s called HD-Ready! That should give you the security to a new purchase can not go wrong with. There’s just a big hole, the new marketing message does not say anything else than that device handle HDTV signals, and also has the necessary connections, nothing else! Basically, the ok. and the fact that you should buy this new eighth bear this logo. About the actual quality of the device but says nothing!
What is the danger?
We say it once very clearly seen with almost any HDTV “Gherkin” better than your standard TV at home. It is simply too “dazzled” and it’s happening. Home and in the evening set the dates, the show turned evil comes awake. The Tagesschau know you inside out and they probably saw better with the old TV. HD you have seen for the first time in the business and had no comparison and thrilled.
What to do?
Leave yourself in the care of a specialist retailer understands his craft. Let yourself be always “normal” TV (SDTV) show and take you with their favorite films. Go to the topic slowly, strike, and not nervous, “blind” if the discounter range again way HD-Ready TVs offer alongside the tomatoes.
