I'm thinking a guy could make a major project out
of this and use three
high speed A/D ahead of some ARM based board that could acquire the video,
scale and convert to taste and then output on HDMI. Should be able to
handle lots of legacy analog formats that way.
This exists, and works even for vector displays!
Any hints as to where this exists? A home project or commercially
available? I'd like to hear more...
Definitely one of my "one of these days" projects, though I'd much
rather use an FPGA than a CPU to handle the video. I'm tired of
how awful composite video looks on my LCD TV because of their
crappy decoding (my Bt878 TV cards from the early 2000s do a much
better job) and the latency looks awful. Expanding it out to more
analog formats would be handy to a lot of folks, I guess. What
kind of price would be palatable to people? I doubt I could get
it down below $70 in any kind of realistic quantity.
oh... excellent. I'd pay $150 for such a thing as long as it converts
to a standard that will be around for a while-- such as DVI/HDMI.
It would be fine if it puts a letter box around the legacy image too--
all the way around-- and doesn't up convert so that one pixel from the
legacy turns into say, five on the modern display. I'm not a big fan
of blooming the image. I'm after as crisp of a image on the new display
as we had with the original tube when it was operating correctly.
The only thing I was brainstorming about when a CPU is involved is that
you could also fork the video into something like VNC protocol and send
it over a network for remote display.
