Ultra HD: Do You Need to Change Your TV Today?

One technology, three appellations (at least)

Ah … What would the universe of high technologies without an innovative marketing to give them body? The advent of the next television standard is accompanied without surprise by colossal stakes. As a result, there was hesitation, and therefore confusion. Yes, we used the verb to the past since; theoretically, the dice are thrown: the high definition of tomorrow will be called Ultra HD or UHD. The term 4K, among the first employees, still exists, but it does not entirely designate the same definition.

 The number of pixels present in the height of the image, the eye is more sensitive to this dimension is known as the screen. Most CRT TVs and DVDs adopted the standard definition (SD) in 576 pixels. The arrival of high definition (HD) in 2005 was initially via what was called HD Ready standards in 720p (p for progressive) and Full HD in 1080p (become HDTV and HDTV 1080p since 2008). That is where we are today. Now, this definition is about to be multiplied by 4: double the width and the height. What makes them 1920 (x 2) x 1080 (x 2) = 3840 x 2160 = 8,294,400 pixels. This definition is called Ultra HD. The 4K is a special format used in the cinema by professionals.

What is Ultra HD for?


In addition to the obvious interest for best LED TV manufacturer in India to revitalize television sales at half-mast with a new park that only wants to be formed, there are benefits for the consumer. The most obvious is the improvement of image quality on large diagonals, where equivalent size pixels well visible in 1080p will become undetectable in 2160p. In fact, this progress will reduce the viewer’s need to retreat and increase the feeling of immersion, “as in the cinema” (an argument that marketing may abuse). One can also take this reasoning upside down by saying that the UHD will allow the manufacturers to propose even larger diagonals without deteriorating the image quality.

Finally, the Ultra HD will theoretically promote the development of 3D technologies without glasses, the latter based on the deal “loss of definition against the gain of points of view.” And in any case, spreading the Ultra HD in homes comes in a certain logic, since today most modern productions are shot in 4K.

UHD TVs have been burgeoning this 2013 edition of the CES: half of the news that we published was about UHD ads. But to say that we will see these new screens in all the cottages shortly, there is a gulf in which we will not obviously rush. Why? Because the Ultra HD is only at its beginnings: it is available in few copies on consistent diagonals, resulting in very high or even prohibitive prices. If prices ultimately decrease, the Ultra HD will remain largely confined to large diagonals (thus expensive). Android LED TV price in India is comparatively lower than Ultra High definition LED TV cost.

In short, is Full HD already outdated?

If in the art, LED TV Android will undoubtedly be an even more marked than the 3D, in the way of doing one finds many similarities: absence of content, technical problems to be overcome, disproportionate prices and the desire to impose a change not necessarily desired by the user. Similarities, with even more significant constraints: Blu-ray support unsuitable as is, just HDMI 1.4 connection sufficient, the introduction of a new codec to generalize, infrastructures too light to support VoD and digital terrestrial transmission.
