On the other hand, the S-video signal out from the VIC-II is really enough to "know" what's going on, and it could most likely be sampled and cleaned, and PAL/NTSC demodulated, to generate a perfect signal. With some automatic level detection, the hardware could learn how the signals from the VIC-II particular actually look re unwanted stripes and similar problems. I.e. a kind of auto-lumafix. -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination. (> <) Come join the dark side. /_|_\ We have cookies.Received on 2019-03-10 21:00:03
