My original video editor prototype has been slowly transforming into a broadcast graphics/video playout system. I've integrated a Blackmagic Decklink device that can interface with broadcast equipment (switchers, big LED walls, etc) via SDI to transmit uncompressed audio/video. Right now it's just playing out the device's HDMI to another monitor, but the concept is there. I managed to put together a very simple animation system last night which makes it much more fun to play around with.
