Is there a way to overlay live tv?

I was hoping there is a way to put a logo on live tv - is this possible? So if the tv show is running and there is my logo in the corner...yeah, no?

You need a video mixer that can mix two signals a la:

Ok, thanks. I am guessing computer video cards can't do this...

You can create the graphic on a computer, but in most cases you will need an SDI out to carry the alpha signal to the mixer (and an SDI in on the mixer.) I know the DataVideo SE-800 has SDI in and will allow you to place graphics with transparency (alpha) over live video.

John Miller (DVinfo member) has a piece of software that can place logo on video coming in from firewire. I am not sure how this might be adapted for your situation.

See www.enosoft.net.
