This sounds like a demo of Apple's 8*24GC graphics accelerator board, which
is expensive but provides significant graphics performance.

What's more interesting is the recently-announced QuickTime, which provides
something more like what you described for the CDTV.  (Small-size display,
full-motion, 15 frames per second, more compression.)

Any Mac II with just the QuickTime software can play back these movies with
no extra hardware.  My understanding is that the QuickTime architecture does
support hardware accelerators, which are transparent to the application
software.  QuickTime also provides support for copy/paste of movies from one
app to another, still image compression (ie JPEG), among other things.
