After the start of production of television sets with screens that have a resolution of 4K (UHD), most TV manufacturers have come up with the name of the technologies that scale the image from a lower resolution to UHD.
Samsung called this technology Remastering Engine. Why this technology is necessary, since the resolution of UHD-content is very small (at this time), and in the next couple of years will increase.
By and large Remastering Engine, it’s just a marketing name meaningless functions. Company statement that they have developed a special algorithm for video processing, which allows you to make low-resolution content close as possible to the UHD. Well, can not be taken seriously.
How Remastering Engine Technology Works
In this instance, set the TV to the matrix of higher resolution, it is necessary to solve a very simple problem to stretch the original image on the screen.
Full HD, the screen with a resolution of 1920×1080 = 2073600 pixels.
UHD, screen with a resolution of 3840×2160 = 8251400 pixels, 4 times greater than Full HD.
It turns out that the information which is transferred by one pixel to be transmitted by 4 pixels, given the density of the pixels in the UHD them anymore but they occupy the same area, the area occupied by one pixel in Full HD, equal to the area occupied by 4 pixels in UHD screen at the same size diagonal TV.
The first figure four pixels, the second if one pixel divided into four parts, and bring the image into 4 pixel we get as a solution UHD.
With such a task can easily handle any computer. What to say because the specifications of the TV compatible with the technical characteristics of a modern phone.
You just need to do one of the conditions set quite a powerful processor that can do the conversion resolution in real time. Of course you can assume that the software can be made more smooth color transitions, but this procedure will require a lot of processing power and correct processing algorithms as it is necessary to compare not only the colors lined up in one line, and take into account the neighboring pixels, this is especially difficult on a dynamic video. Most likely is really happening instead of just representation of one pixel information is transferred by 4 pixels.
But for a variety of tasks including content conversion, as all content not UHD format, needed computing resources, so TVs with screen resolution of UHD set processors with 8 cores. And if the original SD format, in this case before the processor a bit more difficult, because UHD need to convert the image was originally a small resolution.
