It’s a digital video output for retro computers that can be applied as a hardware modification. These devices originally only had analog outputs [1], so getting a digital signal enables a much cleaner conversion to modern video standards.
The LumaCode signal can be visually inspected on a standard analog TV, which is nice:
“…it is possible to just plug it into any TV that has a composite video or mono input jack. The image will then show some grayscale pattern roughly resembling the original picture.”
[1] Not so clear-cut, as some computers of the era did have digital outputs for vendor-specific monitors.
