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 black lines?

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.
