While at Infocomm, I got to check out the Sony Edge Video Analytics system – along with certain Sony cameras, you can  overlay, and replace whatever you need. 

The REA-C1000 device connects to a computer to do the magic. The presenter is in front of a white board, but a presentation is what you see. No chroma-key background needed. Further, you don’t need to worry of the color of your clothing, as it doesn’t matter to the device.

You can also set up the whiteboard to overlay the presenter. In this case, Edge picks up the drawings, then overlays the information over you. You can make the image opaque, or more dominant. 

Edge REA-C1000 can present in 4k, and can also be used with PTZ cameras using auto tracking. 

This device won’t be available until Fall, and no prices have been given. For more information, check out Sony’s webpage.
