The Blue Box Group SDI to HDMI Converter from Cobalt allows you to monitor broadcast SDI video sources on an inexpensive HDMI monitor. It is notable because it can power from USB or the included AC adapter. You can even have both the USB and AC adapter connected at the same time for redundancy. It supports SD, HD and 3G-SDI signals on the input side and outputs a reclocked version of the incoming signal through the loop-out for connecting to another downstream SDI device.
