The
Blackmagic Design DeckLink Duo is a video-editing capture card
consisting of 2 independent SDI inputs and outputs, both supporting SD
and HD video formats that can be inter-switched; each SDI input or
output could be a different video standard as well as a different
content stream.
The DeckLink Duo can capture and playback at the same time making it
perfect for developers who need 2 completely independent capture and
playback streams in and out of a computer. It includes a common
tri-sync / black burst reference, and appears as 2 independent SDI
cards to the computer, but only uses a single PCI Express slot. It
supports Mac, Windows, and Linux OS.
