They won't tell you it's NNs but it is. Sony distributes a lot of movies, they use their database of movies to train the upscaling models (which is obviously NNs https://github.com/nagadomi/waifu2x https://github.com/nagadomi/waifu2x ) and then put the chip in the TV. It's something almost equivalent to storing Pride and Prejudice and Zombies in your TV in 4K, and then reproducing it when they match it with what's playing on TV.

It does not mention anything about neural networks in that link. How do you know? I looked up that Sony chip, and I can't find anything "neural" about it either. I don't quite understand what you mean by: "It's something almost equivalent to storing Pride and Prejudice and Zombies in your TV in 4K, and then reproducing it when they match it with what's playing on TV." Can you explain? What exactly do they have to store in the TV?

  Well, Sony Pictures is huge. Their database of movies is enormous. (Pride and Prejudice and Zombies is one of the movies distributed by Sony) Imagine they stored all of the movies they distribute in 4K in your TV. Whenever the movie is displayed they just find it in the database and reproduce the 4K version. Of course, that is very much infeasible, it requires too large of a storage. What they do is something like Waifu2x I linked, they train a neural network to learn how to properly upscale movies. They put the "algorithm" on the chip, and its fast enough for real time usage.

    It seems like you're speculating. Unless you're familiar with the details of their chip, your guess is as good as mine.

      I don't have to be familiar, you can know state of the art deterministic upscalers and their image quality, and know state of the art statistical upscalers and their image quality. When you see side-by-side for these upscalers, it's obvious they aren't that good in deterministic upscaling.
