HDMI Video overlay using NeTV?

Just curious if anyone has tinkered with an NeTV unit for injecting overlays on to their displays (via HDMI)?

This seems like it would be an awesome way to get visual confirmations of Smart Home processes and also injecting say Security Video feeds after an event trigger (door bell, camera movement, etc).


You can see a demo video here:



Nope but seems interesting, i’ll have a go at it when time allows it
