Hi,
We need to add plain text (and maybe simple graphics) to a live
color s-video signal. The text is a timestamp (to seconds or tenths) and
a temperature for a scientific application.

We already have all of the data in a labview data acquisition application,

but we need to add it to the video LIVE.

If I have to write CIN's or something like that to talk to the card/box,
I
don't mind.

Anybody know anything about hardware that might let us do something
like this?

Thanks.
Bob

Bob,

Why not send the information out via a serial port to something like the

Bob,

I am using VigraVision-PCI frame grabber with Labview. It displays live video in a window as an underlay, on which Labview can display anything. The frame grabber can input and output color S-video.
You can write into the frame buffer if you prefer to see the video on an external video monitor.
I use the DLL provided with the board to interface with Labview.
See: http://www.visicom.com/products/vigra/vigravision.html.

Hope this helps you,
Eyal Sapir
