Blackmagic Design makes 12G-SDI a reality with end to end support in their product line. This allows USD/4K at 60p utilizing 1 SDI cable with full backward compatibility for 6G and 3G SDI. This is a no brainer if you are outfitting an OB (Outside Broadcast) truck or studio. 12G-SDI ensure future proofing for 4K/UHD going into the future.. Add to this their new Teranex converters allowing you to bridge to your older equipment with little effort.
Blackmagic Design seems to be on a winning combination here.
