One possible problem with NTSC that is a requirement for Broadcast Quality
Gear, but is no problem for semi-pro and amateur video gear is the RS170-A NTSC
spec item which states that the sub-carrier signal must be synchronous with the
Horizontal Sync signal, and that it is phase aligned so that at the 11th line
of horizontal sync in color frame 1 the subcarrier signal is zero-crossing, and
positive going. (This would be at the rising edge of the sync.) Any video
source that doesn't meet that requirement will look fine and record fine on
just about every type of video gear except 'true' broadcast tape recorders (ie
Ampex and Sony 1 inch machines) I don't know what the toaster puts out, but if
it A: has NTSC out which doesn't meet this spec, then if it has RGB out AND
genlock, you could use an external broadcast NTSC encoder with a sync-pulse
generator to obtain broadcast output.
Hope this helps...
