Actually it has a video frame grabber (lets split some hairs here) which
implies real-time digitization, where as a digitizer may (and often is)
a slow scan device like digi-view.

What is unique about the Toaster frame grabber is that it captures 8
consequtive fields (4 frames) of video in order to achieve full NTSC
color resolution. I believe it takes 4 fields to fully define NTSC
color. A software a gadget is provided to remove any motion that may occur
in those frames. What I am wondering is how other broadcast freeze
frames deal with this problem. Anybody know? And what about other Amiga
frame grabbers?
