I'm not sure this is terribly practical for console capture unless you're a signal processing hacker who really doesn't want to go out and buy a capture device - decent consumer-level capture devices use some really fancy, carefully-optimized filtering to produce high quality pictures with minimal artifacting, and it'd probably take quite a bit of development and CPU time just to match the off the shelf stuff.

A reasonably priced and good quality bodge is described in "The Best Easy Way to Capture Analog Video (it's a little weird)" https://www.youtube.com/watch?v=ZC5Zr3NC2PY https://www.youtube.com/watch?v=ZC5Zr3NC2PY

  So he has a $25 RCA-to-HDMI and a $70 HDMI capture card for around $100. A fully assembled Domesday board is also somewhere $100 according to https://forum.lddb.com/viewtopic.php?p=100903&sid=a582ac9ebcad2b37d24930ac444a2311#p100903 https://forum.lddb.com/viewtopic.php?p=100903&sid=a582ac9ebc..., although I guess it could be higher without a good PCB supplier. The article's Airspy R2 SDR is $169. There's a PAL decoder in https://github.com/happycube/ld-decode/blob/3d5cdeddbaf4515b41d0dff2c43faa51d649c132/tools/ld-comb-pal/palcolour.cpp#L50 https://github.com/happycube/ld-decode/blob/3d5cdeddbaf4515b..., I'm guessing it could be adapted to the article's purposes with some work. https://twitter.com/windyoona/status/1163043586314821635 https://twitter.com/windyoona/status/1163043586314821635 says she was looking at it.

  Despite my love for his channel, content, and personality, I think he was hugely in the wrong here. His example setup provided no better quality than my experience with a cheap analog capture device from ebay[0], though his is more pliable for other devices.
