It's very hard to simulate this 'upmix'. A CRT TV actually moves the
electron beam across the screen and the phosphor has some time it
stays illuminated after being hit by the beam. This is very hard to
simulate with a digital screen which is either on or off, or has some
slowness by itself which is different from how a CRT screen works.
The dscaler project has implemented some of the best deinterlacing
algorithms and most of the tvtime algorithms are implemented (to my
knowledge) with basis in dscaler source / ideas. See http://
dscaler.org/ . dscaler basically is a deinterlace and display program
that takes input from bt8x8 based capture cards.
Someone on that project had an idea to create a setup where the
display hardware was synced to the input clock of the capture card,
but I'm not sure if anything ever came out of that idea.
