Hi,
I've seen lots of development work related to capturing NTSC/PAL video
and simply displaying it (video4linux, video4linux2 for TV tuner cards,
etc.)
However, I haven't seen much (any ...?) information or projects related
to overlaying graphics on top of captured video.

I don't think you can do what you propose in real-time, at that frame rate.
Also, if you do it the way you describe you will get intolerable flicker, as
you redraw the graphics over the video. If you draw the graphics into the
memory buffer before copying it to the screen you will get no flicker.
