Well, a large part of the population around the world still considers television as part of their major source of entertainment; and it indeed is. Over the years, the so-called ‘idiot box’ has evolved and has been revolutionized by the manufacturers. Televisions now come with more features than ever. However, the variety is so large that televisions are segregated on the basis of the picture and audio clarity than anything else.
HDTV stands for high definition television. The looming difference between HDTV and regular TV is the way in which the TV signal is transmitted from the source to the TV. Of course, this is the reason why you can easily mark the difference in picture quality. In fact, HDTV is twice as good as a standard definition TV. A regular TV has drastically lower resolution. The technology used in HDTV started in the United States of America in the early 1990s.
HDTV is broadcasted digitally and, therefore, not all typical soaps or movies can be watched on regular TV. One of the best HDTVs available in the market is Samsung 1080p HDTV. Samsung 1080p HDTV is as beautiful aesthetically as it is in picture quality. The exclusive design combines texture and color that will complement any kind of room or ambience. It has some seriously advanced and innovative viewing options. Last month, I bought a Panasonic HDTV.
Panasonic HDTV has out-of-the-world audio and image clarity. The experience of watching a high definition movie and your pictures on this TV is unbelievable. The 32-inch Panasonic Viera LCD TV (model TC L32C22) is a world-class TV with plenty of choices to change settings. It also has a SD card slot.
In terms of HDTV, the signal is directly sent to the dish located on your premises. However, in a regular TV, the signal is sent via a cable that runs till the TV. The next time you are out there watching a football match, try viewing it on HDTV. If you are a fan of Messi, you’ll love all the more!
Why HD TV is better
HDTV is touted as the next new generation television. It is suggested that in the coming years or so, the existing analog (CRT; cathode-ray tube) televisions would be a thing of the past. Already America is going all out for promoting HDTVs (high-definition televisions) in a big way. But is everything all right with HDTV as it is suggested to be or could there be any downside to this television? Let’s find out…
What makes HDTVs superior than analog televisions?
The primary difference is in the aspect ratio. Typically the aspect ratio of an analog television is 4:3. This makes an average analog television 4 feet in width and 3 feet in height, which gives it almost a square shape. On the contrary, the aspect ratio of high-definition televisions is usually 16:9. This makes a HDTV like a Sony Bravia 1080p tv, 78 percent wider compared to its height, giving it a trendy and attractive rectangular shape. The wide screen appearance of HDTV also has another distinct advantage – it gives viewers similar viewing experience as watching in a theater will give.
The second difference is in the pixel resolution. Generally analog televisions can display at a resolution of about 210,000 pixels/image, while for HDTVs the resolution may go up to 2, 073,600 pixels/image. The increase in pixel resolution ensures better image quality than standard analog televisions.
Moreover, increased refreshed rate in HDTVs ensures that there is no blurring of images, unlike standard analog televisions. Refresh rate is the rate at which a screen image is refreshed in a second. In a Viewsonic LCD television, the refresh rate is typically 120 Hz. Higher refresh rate generally produce sharper image quality than a standard 60 Hz HDTV or an analog television.
How HDTV can be harmful to our vision?
It is suggested that the digital frequencies of HDTV could make eyes work in a way which are not natural to them. This may put unnecessary strain on our eye muscles, thereby affecting the way our eyes focus on objects or images. Though further research is needed to validate the theory, it is something one needs to ponder about.
How to keep eyes relaxed while watching television?
It is always better not to watch television in a completely dark room as this can put more strain on your eyes. Moreover, it is suggested that the bigger the size of a television, the farther away one should sit from it. For example, if you have bought a HDTV 50 in widescreen, make sure that you are sitting at least 10 feet (3 meters) away from your set. You may also like to ensure that the room where your television is placed is properly illuminated. A soft light behind the television can go a long way in keeping your eyes relaxed.
