Re: Open hardware AV to digital conversion

I've been watching his youtube videos for a while now: https://www.youtube.com/channel/UCKxlmgjrTsmNufTlkiZblvAI suggested he do RGBI for C128 a few months ago

Have you guys seen this project from the TRS-80 CoCo mailing list?

That's almost exactly what I proposed and discuss with Marko and Gerrit for some time already, but I seem to be the most enthusiastic one among us ;-)

I have a clear vision of what I want to achieve and I believe it being well achievable. In a nutshell:
- apply all analogue patches on the VIC signal 
- sample each line
- apply simple digital filtering 
- reconstruct proper, norm compliant, interlaced signal in almost real time 
- output the signal 

This alone should increase the chances of an upscaler to catch on and output a decent DVI / HDMI well to the nineties of percents.

Once having this working well, we could add "native" HDMI encoding on board.

What kind of processing power would be needed if we just sampled the
PAL/NTSC video signal with A/D and processed it in software to
reconstruct the video? Something like this but in real time:

Could something like a Raspberry Pi do it? I suspect not, but maybe
it's
a route worth exploring?
