The SDI to HDMI and HDMI to SDI Micro Converters are a pair of converters designed and manufactured by Blackmagic Design.
The build itself is incredibly small and light weight, but also sturdy thanks to its aluminium shell.
Each converter comes in a similar design, the only difference being the routing of the additional SDI port. On the SDI -> HDMI version this is an SDI Loop Out and on the HDMI -> SDI version this is an additional SDI Out. Both converters are powered by the included usb power supply.
The Micro Converters are great for many situations from splitting a presentation feed to sending a program feed to a separate tv.
The converters have a maximum supported resolution of 1080p 59.94.
