>Also, how about Non Linear editing systems and Linear editing systems?
On-line traditionally means the editing equipment is hooked up to a switcher,
ADO-ish 2 1/2D picture flipper, a bunch of tape decks (3/4,1",Beta,D1,D2 etc)
,misc signal analysis equipment and output NTSC broadcast quality video.
Off-line just has 2 or 3 tape decks and an editor that keeps track of what
cuts you make. This list of cuts is carried into the above expensive edit
bay and run through the 'real' equipment that makes your show.
Non-linear off-line uses 1 deck (or maybe pre-digitized material on a disk)
and computer to replace the above system. Non-linear saves time or allows
more fiddle time by not requiring all the tape shuttle and re-editing
time that sliding/replacing edits causes.

I have seen material that claims 3/4"-BetaSP quality. It is usually MPEG/JPEG
compressed, so the limits of those systems apply. (Pretty good, falls down
on occasion- very quickly changing scenes that have a lot of detail)
