I am trying to display two live video screens as one live screen "layered" "not side by side"
<p>I have a live screen on my computer from a video camera, and a live screen on my computer from a spectrum scope, see <a href="http://www.youtube.com/watch?v=RFPojOo-hI4" rel="nofollow">http://www.youtube.com/watch?v=RFPojOo-hI4</a>  for a video of this display.</p>

<p>I want to layer the top portion of the scope screen "the part with spikes, not vertical bars"
onto a screen with the live video camera screen, so that on one screen a live video is shown with the frequency wavelength moving across it "in a park showing a bench with the frequency moving across it"</p>

<p>and so that on another window, "i assume by making each window smaller i can display two screens side by side"
i can show the entire scope display.</p>

<p>What is the name of a computer program that allows me to do this?</p>

<p>If there are none, what is the name of a program that allws me to develop my own program to do this?</p>

<p>it should be simple, as i am just trying to display two feeds "inputs" on one screen</p>
