I demonstrated the digital quad box for BARCFest attendees and attracted lots of interest. I had two TV backpack transmitters of my own placed in corners of the building, plus a signal from Jim KH6HTV showing home video, plus a video input from a stationary drone camera belonging to Allen KØARK (the receiver is the white device on the far left of the table; it is connected directly into the HDMI switch).

On the right I have a laptop receiving the video stream over an Ethernet network, using a Monarch HD streaming appliance (the silver part in the middle of the quad box).

The embedded HDMI switch makes it easy to substitute video sources into the quad processor as well as choose which images are shown on monitors or fed into the streaming device.
