This BNC Female to DIN 1.0/2.3 RG-179 Cable - 6'  is necessary for connecting devices that employ the smaller DIN 1.0/2.3 connectors to devices that use the more common BNC connection. This is used primarily for 3G/HD/SD-SDI and genlock transmission. Manufacturers that employ the DIN 1.0/2.3 connection (also known as Mini DIN) include RED and Blackmagic Design (for its Hyperdeck line). This RG-179 cable is thinner than most other types of coaxial cable, for extra flexibility.
