The presentation I saw at Apple did the video on a normal projection
television.  Somehow they were getting the video signal off of the CD-ROM,
through the Mac (IIfx) and onto an NTSC device.  The display was not on
the Mac screen at all.

However, I also saw similar video on the Mac screen in a HyperCard window.
This time, though, they were using some sort of card that takes a video
signal and patches it through onto a bit-plane of the Mac screen.

Mind you, all of this hardware cost megabucks.  The CDTV, on the other hand,
costs around $1000 (in Canada) which I'm sure is about a quarter of the
special video card for the Mac alone.

On the surface, the stuff Apple is doing is much more impressive than
Commodore.  When you realize that Apple does its stuff on a $10k system
and Commodore on a $1k system, the tables are turned.  Of course, someday
Apple hopes to have compressed video, too.  I hope by then Commodore is
either very well entrenched or has something new up its sleeve.
