DeckLink Duo |
|
|
Perfect for developers who need two completely independent capture and playback streams.
|
|
Introduction
|
| |
The DeckLink Duo appears as two independent SDI cards to the computer, but only uses a single PCI Express slot.
|
| |
The DeckLink Duo is perfect for developers who need two completely independent capture and playback streams in and
out of a computer, as both capture and playback channels are completely independent. There are two SDI inputs, two
SDI outputs plus a common tri-sync/black burst reference on the card edge.
The DeckLink Duo is perfect for servers where there are multiple streams or simultaneous capture and playbacks per
system.
The DeckLink Duo is compatible with Windows, Apple Mac OS X and Linux computers.
