Blackmagic Design Micro Converter BiDirectional SDI/HDMI 3G without PSU (CONVBDC/SDI/HDMI03G).
The Blackmagic Micro Converters are incredibly tiny broadcast quality video converters. The rugged, miniaturized design of Blackmagic Micro Converters makes them small enough to be used anywhere and conveniently hidden out of sight! You get HDMI and professional 3G-SDI connections for working with all SD and HD formats up to 1080p60, along with an external power supply. You can even power them over USB, so Micro Converters can be powered by big screen televisions or laptop computers without having to plug them into the wall!
