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 Steve From: Chris Osborn <fozztexx@fozztexx.com> To: cbm-hackers@musoftware.de Sent: Sunday, January 4, 2015 3:02 PM Subject: Re: Open hardware AV to digital conversion Have you guys seen this project from the TRS-80 CoCo mailing list? https://sites.google.com/site/tandycocoloco/rgb2vga On Jan 4, 2015, at 12:00 PM, silverdr@wfmh.org.pl wrote: 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. -- Sent from mobile device. Please have understanding.

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: http://www.techmind.org/vd/vidmk2.html Could something like a Raspberry Pi do it? I suspect not, but maybe it's a route worth exploring? Regards, Michau.
