Display six NTSC inputs to a single 6 way split screen HD output?

[MichaelFarley]

I would like to display 6 NTSC standard definition (640x480) video signals via RCA composite or 75ohm BNC, simultaneously on a single HDTV in a 6-way split screen format via HDMI, DVI, or VGA. The video should be realtime (~30fps). Does anyone know how I can accomplish this?

Thank you!

What's your budget?

Ah great, thank you! I'm not in the AV business and I didn't know the term for the equipment, multiviewer. I've been searching for days. I knew security DVRs would display split screen, mostly using 4 inputs to a SD monitor, but I couldn't find 6 inputs for an HD monitor. Much of these items are out of my budget <$1000, but knowing just this one term, multiviewer, has opened up a lot of options. Thanks again.
