Overlaying Graphics on a Live TV Signal
on Jul 9, 2008 at 9:58:10 pm

Hello, I am a new member of this forum. In my office, we have an LCD TV in the lobby tuned to CNBC. I would like to find a way to overlay some graphics, specifically our company logo, onto the screen. My first thought was some kind of video capture card on a PC that is able to overlay graphics. Does anyone know of the right solution for this problem? I've googled all over the place but couldn't find what I was looking for. I know how to do this in Adobe Premeire with pre-recorded video, but want a solution for Live TV. Thanks in advance for your help.

The simplest solution would be hardware-based. You would have to take video out from the cable box and run it through a frame synchronizer. You would need a character generator and switcher with keyer, or a standalone logo inserter to key your logo over the stabilized framesync'd video.

I would be curious to know if it is "legal" to alter or modify in this way, network material that is being displayed to the public.

Thanks for your help. I am afraid I am a total novice when it comes to broadcast equipment. Can you explain in a little more depth? I am really looking for a solution that would cost no more than $300 or so.
