Blackmagic Design Decklink Duo 2

The Blackmagic DeckLink Duo 2 is a capture and playback card built for media servers, digital signage, and real-time processing setups that need multiple independent video channels on a single PCIe slot. It's designed for developers and OEMs building flexible, high-throughput video I/O systems.

• Four independent 3G-SDI connections: Each connection can input or output a completely different video standard or content stream at the same time, supporting SD and HD up to 1080p60.
• Simultaneous capture and playback: Can capture and play back video at the same time, with a reference connection for black burst/tri-sync.
• Single PCIe slot footprint: Uses one 4-lane Generation 2 PCI Express slot while appearing to the host computer as four independent SDI cards.
• SDK for custom I/O configuration: Developers can configure the four SDI connections in any combination of inputs and outputs to fit their system.
