Re: Open hardware AV to digital conversion

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.
