We watch so much of our day-to-day video on our computers.  But if you ever try to use a computer’s signal in the pro video world, you are in for a rude surprise.  This lovely box takes VGA, DVI or even Composite signals in, and regardless of their resolution/colour space/frame rate/scan format, outputs them as regulated HD-SDI or HDMI.  If the originating signal is not in the 16×9 aspect ratio, you can make it fit either by stretching it or displaying it with black bars.  The box has dip switches and a printed menu to control its functions locally, or you can control it over a USB connection using free software.  You can add or de-imbed audio depending on which direction you’re going.
