The Set Top Box Is Getting A Retrofit

Will processors jumpstart 8K? System-on-chip (SoC) designers and home device makers are experimenting with AI techniques to upscale high-definition or even standard-definition programs in a way that looks natural and realistic. Here’s how it works. Rather than stretching an image over a wider battery of pixels (causing pixelation) or filling in the new pixels by extrapolating informatio... » read more
