Blurred perspective HD

blurred-perspective-hd-raqwe.com-01


In one of the articles I have already said that a few years he lived without a TV, and then immediately bought the most modern – with support for 3D and Smart TV. And, of course, with a resolution of Full HD.


Over time, the TV fit into the life and now it seems quite useful acquisition. However, the technology 3D, for which I overpaid a good third of the price, it is not “gone”.


Problems with the relevant content is not, the good movies can be bought on Blu-ray, available through the services of Smart TV, or enlist the help of sources, the names of which in polite society are not mentioned. But, as it turned out, the need to sit in front of TV for special glasses is not offset by additional impressions of 3D-effects. I’m in a movie theater, I try to buy tickets to the sessions with the traditional 2D-image, and that’s home innovations have not taken root.


A Smart TV, on the contrary, was quite a useful thing. On the possibility of order movies directly from the menu I mentioned, but the neighborhood spelled dozen online services where you can watch movies for free. Well, maybe some of them show commercials, but only one at a time and the strength of every half hour. Also, the TV is an app major domestic TV channels, and through them the available archives and series of gears, and with neatly cut advertising. With all this abundance to all terrestrial channels do not reach.


I watch movies via console or Apple TV on a DLNA network drive. First, of course, chose only the resolution Full HD, and then suddenly found that I do not see the difference between it and the HD. With half a meter, of course, notice can be a little less clarity. But with two – way. And with five or more so it is not visible. As a result, time-saving was always choose 720p (another name for HD). After all, if there is no difference – why pump more? By the way, the ability of the TV to “pull” image are staggering. Recently fed him the video was originally prepared for the Sony PSP and has a width of the frame 480. So I said it’s about 10 minutes, because at first the picture quality is quite satisfying.


But the producers did not really please the TV if it will be enough to Full HD resolution and we can rule out the purchase of a new model of the plans for the coming years. And now the drums beat marketing: “Buy Ultra HD! Enjoy true high definition! “. These marvels of technology shown at CES earlier this year, and six months later they have reached and domestic counters. Prices, however, slightly shocking – from 200 thousand to 1.5 million rubles. But like soon there will be more models available 100 thousand


That’s just it seems to me that in the near future to push the ultra-high resolution mass market will not work. I’m not one of those who believes the resolution Ultra HD excessive. Yes, the 3840 × 2160 pixels – this is a lot, however, and 1920 × 1080 for another five years ago, it seemed a shockingly large. However, nothing used to. And now the matrix Full HD is not uncommon even in smartphones. In the end, there is no definition of excess, and the girls so interesting to examine the tiniest wrinkles on the faces of your favorite actresses. But on the way Ultra HD to the masses, there are two really serious obstacles.


First, with the same 3 m to distinguish from Full HD Ultra HD is not easy. The difference between SD and HD was visible to the naked eye, but here it is necessary to look closely. And I’m afraid, for this crisis weary of working people refuse to pay.


Second, desperately ready content delivery infrastructure. Resolution of 3840 × 2160 pixels – an 8 megapixel (Full HD – only 2 megapixels). More recently, it was considered a decent resolution even in the mirrored chamber. One 8-megapixel shot, even with very high compression is 1 MB. They must be replaced at 60 frames / s, and in some cases, from 120 frames / sec. Thus, we need a network capable pump with online viewing of at least 600 Mbit / s. This speed Internet connection is not available the great majority of households in the world. However, the TV people seem to have managed to pack in Ultra HD channel width of 40 Mbit / s, but this is achieved by absolutely ruthless image compression and reduce the frame rate. In addition, this figure seems to be acceptable to you and me, but in the U.S., Canada or China is still considered a very decent channel to homeownership “thickness” of 20 Mbit / s, and even doubling its capacity – in the future (in fact, to even tripling, because you can not give away all one TV channel).


But, maybe, we will watch the movie offline? There is none. The film Ultra HD resolution is approximately 80-100 Gbytes, whereas a dual-layer Blu-Ray placed only 50 GB. It is time to sell blockbusters on the hard drives, so only very few people will appreciate the price. Buying digital copies of the online stores becomes a lesson for the patient, because even with a fairly fast 50 Mbps channel from the purchase date to start viewing will take place around 5 pm Most asleep without waiting.


In general, to all appearances, a year and a half, TVs with support for Ultra HD will be equal in price to the current top-end models, Full HD, and start buying. And use with outdated content. And three years later, you see, the infrastructure will be tightened, and people are finally able to understand what paid the money.


Here’s a look into the future and learn – in which digital paradise will hunt us then?
