- I assume that you have standard NTSC video that you want to put on
- your computer monitor. If it is a composite monitor, it should work fine.
- If you have an RGB monitor, you can make a circuit using a chip (can't remember
- the number) that converts NTSC to RGB. It was profiled in Radio-Electronics
- a year or two back. It was in their descrambling series.
- However if you are starting with RF, you'll want to get a tuner--or run it
- through your VCR, to get the baseband video (then go back to the beginning
- of this paragraph).
- Hope this helps...
