They created code which [interrogated two, pre-broadcast, adjacent lines] which would emerge, placed in between the real signal material, across a video screen, [interpolating a 'new', artificial broadcast line] from their algorithm, creating a high-resolution image from low-res..

Reviewing https://en.wikipedia.org/wiki/Digita...ve#Compression

The original video compression scheme, called Presentation Level Video, was asymmetric in that a Digital VAX-11/750 minicomputer was used to compress the video in non-real time to 30 frames per second with a resolution of 320x240. Encoding was performed by Intel at its facilities or at licensed encoding facilities set up by Intel.[4] Video compression involved coding both still frames and motion-compensated residuals using Vector Quantization in dimensions 1, 2, and 4. The resulting file (in the .AVS format) was displayed in realtime on an IBM PC-AT (i286) with the add-in boards providing decompression and display functions at NTSC (30 frame/s) resolutions.

So they capture a still frame and then extract the differences in subsequent frames to upscale from 320x240 to NTSC (640x480).

OpenAI adds 'Outpainting' feature to its AI system, DALL-E, allowing ...
2 Sept 2022Outpainting can extend original images, create larger images in different aspect ratios, and much more. Plus, the system considers existing shadows, reflections and textures, to help make newly-generated content appear natural. Outpainting is now available to all DALL-E users on a desktop.
