few years ago, everyone loved the HD TV. But today, the picture quality on anyone unless it does not have any impact. Anyone who has in recent years decided to buy a new TV, you may enjoy the pictures in 1080p, or at least HD Ready. Suppliers tempt broadcasts channels at high resolutions, but when we look closely at the painting, the spell is broken. Equipment manufacturers are aware of this fact and are preparing a revolution under the banner of Ultra HDTV. The new standard display is impress the audience. The Polish have already hit the first 4K TVs, but the price can pin down.
If you look at today’s TVs and even compare them with computer monitors and mobile phones, we can immediately notice that something is wrong. Why? Full HD TVs have become a kind of standard. More and more programs are broadcast in this quality, but the problem is that today it is hard to call it good. The difference between the image in SDTV and HDTV she looked a few years ago.

smartphones have much better picture!
Computer monitors offer quality 1080p, or even better, not to mention mobile phones, which on screens smaller than 5 inches capable of displaying razor sharp images with a resolution of 1920×1080 pixels. Leads the smartphone HTC One, the display boasts a pixel density averaging an incredible 468 dots per inch! When we extend this picture say to 40 inches, the spell is broken. On a TV of this size, which is not yet large, pixel density drops below 50 per inch. And let’s be honest: today deciding to buy a new receiver will measure up – in 47 or even 55 inches. On these screens materials in Full HD fall really pale. The picture is not sharp, and individual points are at a distance visible to the naked okiem.W latest smartphones, we will not be able to see the individual components of the image, unless you will use a magnifying glass.
But the producers are preparing something new. The era of ultra-definition video, which is impress the audience and the way consumer electronics repair budgets. The current standard HDTV is an image with a resolution of 1920×1080, consisting of more than 2 million pixels. The new standards are designed to provide a more detailed picture.
4K already in Poland
sales in Poland had passed the first 4K TVs. The image displayed on the quality of a 4-fold greater detail compared to HD. It consists of more than 8 million pixels, which corresponds to a resolution of 35 mm film. Unfortunately, this high-resolution puts high demands on hardware. To save the material in the quality required memory resources are vast and highly efficient equipment, so that the new standard is expensive and still underdeveloped.

When will we see the magic of 4K, we will never delight in Full HD movies. 4K image is so crisp and detailed that you can easily read a newspaper at him from a distance of several meters. However, if the new technology is available only to people with a really wealthy portfolio. Sony and LG 4K TV offers customers a gigantic diagonal of 84 inches (214 cm). In an average apartment would occupy half the TV wall. Unfortunately, the price allows the legs. LG TV costs almost 80 thousand. z?, and a 4K Sony have to pay even more because almost 100 thousand. z?. It is more than that of a new car! For example, the price of LG TV we could buy two Fords Fiesta, and instead of Sony TV could afford to buy a new Skoda Octavia trim the richest and most powerful engine.

However, too high a price is soon to cease to be a problem. Sony plans to sell less than 4K TV. 55-inch receiver is expected to cost about 20 thousand. z?. It is still very much, especially the Chinese offer 4K TVs at a much lower cost. 50-inch 4K receiver Seiki’s only costs $ 1400
price is not the only problem
But the price is not the only barrier that limits the development of 4K. Another problem is the availability of content. For now, 4K video database consists of only about 100 movies. However, it is encouraging that more and more production using high resolution cameras. The 4K are available such productions as “After Earth”, “Skyfall” and “Django”. Another problem is the TV channels. Broadcasters introduce standard HD and for the moment there are no hints of changes in this regard. Japan, however, is already preparing a revolution in his country and is a pioneer in the implementation of 4K. The government wants to put into place as a new standard to help domestic companies – Sony, Panasonic, Sharp, Toshiba. The new standard would be implemented already in 2014. Sony dreamed up for next year to be able to transmit the World Cup matches in football in Brazil is in the quality of 4K.
But perhaps the biggest problem that manufacturers have to face is the size of files that are stored 4K material. The average movie in this quality is more than 100 GB – DVD video for comparison is 4.38 GB, a single-layer Blu-ray disc capacity of 25 GB of data. Sony equips its players 4K hard drives, but they are able to accommodate up to 10 movies. The problem is also becoming internet speed. Experts fear today that the smartphone revolution in the years to clog the Internet connection. In 2014, the first year is expected to launch service that provides materials with 4K resolution. The problem is that, with even the fastest connection, the film will fetch at least one hour – the standard links that we have now in our homes would take at least 15 hours.
What the 4K? 8K!
Train 4K can no longer be stopped. The large, thin televisions, expanded Smart TV and 3D today is not enough. We have an appetite for more and more! Manufacturers need to rush the introduction of new standards – appropriates that on the horizon has become standard 8K. The materials of this quality will have a resolution of 33 million pixels (Full HD is only 2 million).
