Situation: HDMI source (STB, PS3, ...) --> HDMI output (TV)
I'm looking for a way to superimpose a computer generated (that is, another DVI/HDMI source) image onto the existing video, using chroma key techniques or picture in picture.
Possible uses are:
* while watching a DVD, display small video feed from security cam (triggered by motion) in the corner of your screen (Picture in Picture)
* while switching channels, briefly present TV programme information on the lower half of the screen; or maybe lookup IMDB info and show it.
* superimpose closed captioning
I'm unable to find any device that will allow me to do this, other than non-HD equipment or really expensive chroma key SDI equipment.
Does any such device exist?
