The CDTV's pseudo-12-bit graphics pale against the 15/24-bit >graphics of the CD-I systems. Marc, CD-I is not 24-bit color, nor 24-bit palette, nor 15 bit. CD-I is DYUV encoded just like DCTV. This means it is limited to composite (same limitations the Toaster has). It also means CD-I will be interlaced on normal-tv's unless it doesn't have >200 lines. BTW, DYUV encoding has some of the same draw backs that HAM has. You can't change colors quick enough (I think you can change instensity every pixel, but color can only be changed every few pixels) Marc, I propose you do an experiment once just to see how FOOLED you are by the "inadequate" resolution of everyday television. Go to your VCR, record a few seconds of video (it's even better if the video has some titling from a TV commercial so you can see that awful flicker from the edges). Now that you have few frames recorder, freeze-frame one with lots o color. Notice anything? Yep, it looks HORRIBLE, reminicent of old CGA dithered GIFS (if you were in SLP, and you have a normal VCR) >> >>-- C-UseNet V0.42d >> Ronald Kushner Life in Hell BBS +1 (313) 939-6666 >> P.O.
