Blackmagic announce software update for all DeckLink models

Blackmagic Design have announced a new software update, with new features for all DeckLink model uncompressed video cards.
This update includes keying support for all standard definition DeckLink modes, a new Disk Speed Test utility, and improvements for DeckLink HD cards.
Blackmagic DeckLink v4.1 now adds video and key output support to DeckLink Pro. Now DeckLink Pro users can connect the two SDI outputs of DeckLink Pro into vision switchers for live keying of graphics over real time video, perfect for graphics presentations on sports, and other live broadcast events.
In addition to the external video and key output provided on DeckLink Pro with the DeckLink v4.1 update, all DeckLink models now include an internal keyer. This allows live keying of video as it's passed from the DeckLink video input to the DeckLink video output, and does not require any external equipment.
All standard definition models of DeckLink are supported with this new internal key feature including DeckLink 1, DeckLink 2, DeckLink Pro and DeckLink SP.
