Analog to VGA conversion
I have a Sony CCD camera connected to a controller that outputs video as
analog RGB with external sync (four cable BNC). The video monitor (NTSC/PAL) used to view the live feed has since died and I'm looking for an alternative for video monitoring. I'd like to use a vga monitor (PC) as a replacement. Not much luck yet finding a suitable conversion device or component. Everything I've read seems to say it isn't that easy. Is it? Or could you use a video card to capture the live video into a PC? A frame grabber would work, but it makes focusing the camera difficult as you have to constantly focus-grab, focus- grab. Best case would be a card that can handle real time live feed. I'm asking for professional advice on options. Video card or otherwise. Video conversion is not my specialty, so I wouldn't mind a dummy's guide sort of approach. Thx. |
Analog to VGA conversion
No easy conversion because the scan rates are so much different.
Best to find a used RGB input video monitor to use or fix the old one. The video capture cards do not even have RGB input but typically only have composite or s-video inputs, some newer high end ones have component input, but no RGB input. Some of the earlier multi-sync VGA monitors that had the bnc connections also would do the standard ntsc and pal frequencies, but those are rare to find now. |

Because the scan rates are totally different, you would need a scaler. These are not cheap, you would be better off spending the money on a new monitor. |
