BlackMagic Decklink Quad SDI¶
The Blackmagic DeckLink Quad SDI card operates as four independent SDI capture and playback cards in one. It includes four SDI inputs and four SDI outputs that can be independently switched between SD and HD video formats, as well as a common black burst/tri-sync input for all four channels. The DeckLink Quad appears as four independent SDI cards to the computer, but only uses a single PCI Express slot.
The DeckLink Quad includes a built in watchdog timer under API control with bypass relays for a robust broadcast solution that automatically switches to bypass if power is lost, or software crashes. Each SDI input and output can be a different video standard as they are all completely independent.
