Line doublers & video games?
Does anyone know if any of the line doublers on the market do
something special for video game input?
They do the 24Hz film and 30Hz video detection and then de-interlace it.
Since most video game machines (PlayStation, N64, Saturn) all do the
half of the lines 60Hz thing, it would seem appropriate if the line
doublers detected this. For video games the latency of the doubler could
be eliminated and the black lines seen on RPTV's could be removed with a
rather simple algorithm.
Or is it just easier to program the front projector to have a special
video game mode that fattens up the scan line inorder to get rid of the
For those of you who are saying NTSC and 60Hz, what the #^@%?
Video games lay the even and odd fields on top of each other so
to halve the vertical resolution and double the frame rate to 60Hz.
Why do they do this? Higher frame rate makes a snappier game, and
lower resolution means less pixels to move around so the processor
can now move more polygons a second.
I realized that a FP will automatically clock to the video game 60Hz/frame
signal and on some front projectors you can just increase the spot
size until the space between the lines is gone.
There is nothing to de-interlace so a line doubler and a video game machine
such as the Nintendo 64 or Sony Playstation is a pointless combination.
Note: It looks like the PSX Tekken3 is different than the past Tekkens,
it is 30Hz interlaced and the picture is more detailed, it doesn't seem as
quick as the previous Tekkens.
