Tech Papers 2021: This paper shows how super resolution can upscale SD/HD to UHD, as tested by France TV at the French Open, delivering sharper 4K quality.
Abstract
Super resolution is a technique that is getting increased attention. It was first deployed in high-end TVs to upconvert content, and now content providers are looking at how it can be used on the production side to guarantee the same high quality on all devices. Different techniques can be used to apply super resolution to SD and HD content for transmitting UHD resolution. During a recent trial with France TV at the French Open, SD content with a 16:9 aspect ratio was processed offline to create UHD content, using a hybrid pipeline of deep restoration and super resolution methods.
