HDTV Buying Guides: Introduction
HDTV and the Main Principles of its Work
Every person wants to make his life out of work more interesting and that’s why people always buy gadgetry. We visit a supermarket, listen to the clever words of the shop assistants and usually don’t understand the single word. Let’s deep into the topic of HDTV as it is really popular now and any potential buyer has to know what he pays for. This article will be your guide in such an interesting and complicated topic as HDTV technology.
HDTV and its Development
HDTV means television of the higher quality of the image. This technology appeared in the 60′s of the former century as the new revolutionary word in technique. Many countries started to develop this invention but the most successfully the technology was used in United Kingdom. HDTV is the technology that changed the previous one called PAL.
PAL stands for Phase Alternating by Line. Why did the new technology capture the hearts of people? Every picture consists from small dots that are called pixels. The more pixels the picture has, the better image is. Just compare, TV’s that work with PAL technology has about 720 (across) and 576 (high). New HDTV technology offers 1920 x 1080. Pixels are arranged in lines and their amount is also important for the image of the high quality.
If PAL technology offers 576 lines, HDTV can provide you for 720 and more lines. And keep in mind that pixels and lines create the image of the high quality, not the size of the screen. A poor woman in a hospital and a solid gentleman in his office will see the picture of the same quality if their TV’s support PAL technology although the size of the device and their trademarks can be really different.
HDTV appeared in the middle of the former century. This format changed the previous one that was called standard. Of course HDTV is more interesting to watch as you feel that it is not just the picture, it is a real world you see on the screen. But remember that if you dream to enjoy HDTV picture, you need to get not just the TV set that supports that technology but also find the broadcast company that supports that same format.
With your old broadcast company you won’t be able to enjoy images with that high quality. So spend some more money and change your company into Sky (in the UK) or something like that. The fineness of the image showed on the screen of TV set that supports HDTV can be various. Don’t worry if you notice that resolution is not 1920 x1080 but 1366 x768. Sometimes the TV set receives PAL wave to change it into HDTV signal and that’s why the resolution is different.
The Essence of Technology
As it was mentioned above, the beauty and fineness of any picture, whether it is photo picture or video picture, depends on the amount of pixels. HDTV technology offers the greater amount of pixels. Besides they stay close to one another and form the vertical lines. The amount of lines in HDTV is much bigger too. Thus you see the image that is more precise, brighter and looks alive. The first people who appreciated HDTV technology were sport fans. They admired all the details of the football match or basketball play and felt that they were on the field themselves.
Sometimes the customers get HDTV devices and become disappointed as they see no difference. Remember that the quality of the picture depends not only on the TV set you have and its technology but also on the signal that is provided by your broadcast company. Contact your company to know the details or simply change it into Sky or any other to enjoy the new quality of image.
