Samsung 8K QLED TV Uses Artificial Intelligence to Upscale SD Content to 8K Resolution

You’ve probably read how artificial intelligence can be applying to modify photos, either repair them, or change the weather in photos from sunny to rainy, and vice versa. Samsung unveiled an 85″ 8K QLED TV right before CES 2018, which should be news by itself, but that I found really intriguing is the TV’s artificial intelligence capabilities that will upscale standard and other resolution content to 8K resolution. The TV will take SD, Full HD or 4K sources runs it through machine learning algorithm to re-create details, reduce noise, and restore edges to bring them back to 8K picture quality. Not your usual “dumb” upscaling 🙂 The TV is said to be equipped with a database that studies and analyzes millions of images in advance to transform low-resolution content into high-resolution, and capable of selecting the optimal filter to convert the source to higher quality. Samsung then explains the images is processed 64 times (how?) to offer natural images in …

Unofficial List of TV boxes Running Android TV OS

Most TV boxes run a modified version of Android operating system for smartphone, and devices based on Google’s Android TV are harder to find, and often country specific since they are tied to local streaming services. Yesterday, I was searching for boxes based on Marvell Armada 1500 Ultra SoC, and first found a couple in Spain and the US, but eventually found a bunch more when I discovered somebody was keeping track of all/most Android TV devices in a page hosted by Google but with no actual affiliation with Google. The devices are sorted in three categories: Pay TV Providers, usually only sold in a specific country with programs in the local language, and a fairly long list Streaming / Gaming – Those are the most famous Android TV TV boxes like Xiaomi Mi Box or Nvidia Shield Android TV with only 6 models in that list TVs with Android TV OS The first list is probably the most interesting …

Inside LG 4K TV, and My (Unsuccessful) Attempt at Repairing It

Long time readers of this blog may remember that I organized a crowdfunding event aiming at raising funds to buy equipment to test 4K TV boxes and mini PCs in early 2015, and one of the items I ended up purchasing was LG 42UB820T 4K television. It worked well for over a year, but I started to notice a single vertical appear on the TV in June, or about 18 months after purchase. A few more lines appeared in the following week, and it appears to have stabilized as shown in the picture below. While I understand that in Europe a 2-year warranty period is legally required, I’m based in Asia, and all I got was a one year warranty for the TV. So I had three choices: Ignore the problem Pay for the repairs Try to repair it myself So far, I’ve selected solution 1. because that’s the easiest one, and the lines don’t matter than much since I …
