Analog as well as digital (RGBI) signals?
A similar problem extends back into the RS-170
composite-mode
era of home computers. Devices from 20 years ago
tossed out
all sorts of approximations of "composite mono
video" and
older TVs might handle it better than newer TVs with
less forgiving circuitry.
Yeah like that shoddy method of generating the "back
porch". You got to watch for that one ;)
I daydreamed about a little gizmo the other day.
Plug it in
as a pass-through with two VGA 15-pin connectors so
I watch
the video. Press a button, capture the image as a
bitmap for me.
Has a USB plug so I can fetch it with another
computer. This would
be great for recording text-mode screens as well as
other VGA-mode
error messages. I'm tired of transcribing them. It
wouldn't
be hard for this device to decipher which video mode
(rez, scan rate, etc.) was being shown and display
it on
a little LCD. With a few adapters, it could handle
non-VGA-ish signals.
Interesting. Along similar lines if the Windows
clipboard thing allowed you to capture multiple screen
shots or portions of text, and insert the one you
choose, it would be a boon.
