Samsung technology converts any video to 8K (or almost that)

ByAdeline Belluz 2019-06-07 218

In April 2019, Samsung announced the arrival of its QLED 8K TVs in Brazil. However, many doubts surround the new technology, which is not yet within reach of the vast majority of consumers.

To clarify the differentials of the new line of TVs and also conduct exclusive demonstrations of its performance, the manufacturer brought experts directly from its headquarters in South Korea to speak at its Technical Summit, an event held last week in Sao Paulo.

Speaking a little about numbers, Samsung's 8K technology promises up to 4,000 nits of brightness and 33 million pixels for image formation. To get an idea, a 4K TV has "only" 8 million pixels and a Full HD has two million. The sum of all this results in more precise contours, more detail in texture, greater depth in scenes, and more crystal-clear colors and images.

Algorithm that improves the quality of images

Leaving pixels and nits a little aside, we need to talk about a "detail" of Samsung's TVs that promises to be the big differential in this new era of image quality: the Quantum 8K processor. It's common to hear about smartphones processors, but when it comes to TV, nobody cares much about it. At least until now.

That's because Samsung's processor is responsible for helping to solve - at least in parts - one of the big current problems: the scarcity of content in 8K. After all, what's the point of having a powerful device, capable of displaying tons of pixels, but not having enough good enough content to be displayed, isn't it?

According to Samsung, its processor uses Artificial Intelligence technology to analyze millions of images and automatically upscale content from any source with lower resolution to a video format "near 8K".

During Samsung's Tech Summit, Simon Lee, Lead Engineer in the Visual Display Business area at Samsung Electronics, explained that the company's so-called Machine Learning Super Resolution (MLSR) uses AI to compare high- and low-resolution versions of the same content and learn technical differences between the two.

Basically, the technology collects data from millions of videos, classifies them based on texture, format, among other characteristics, and then creates formulas to define each content. Content is refined in real time, regardless of its native format (HD, FHD, or even UHD).

The summary of opera is that Samsung's upscaling allows routine consumer content, such as open or pay TV shows, as well as series, movies and the like, to be viewed in higher quality, even without having been filmed in 8K.
