Can i transfer video data between two Decklink devices?

We have bought Decklink Quad and Decklink SDI cards. And we plan to use Decklink Quad in one computer to capture a high resolution video data by Blackmagic SDK, and then transfer the video data to DeckLink SDI card in anohter computer also by Blackmagic SDK APIs. The process should be in real time.

And we have a try but not success.

I want know whether the Decklink Quad card can output the video data to Decklink SDI card. Thanks in advance.

in declink cards u can only input or output .. declink quad is 4x cards on one cards .. so if U use all 4 inputs , u cant output simultaneously .. Then U need onlu 3 inputs , and 1 output on declink quad ..

Pthkin, Thanks a lot for your suggestions. It means we will need 2x decklink quad cards. I will have a try.

One more comments. I heared somebody said that Decklink Quad supports 4 inputs and 4 outputs simutaneously with some commerial softwares. But i try the SDK sample, the conclusion is Decklink quad cann't support that.
Is there any APIs which can make Decklink Quad support simutaneously 4 input and 4 output?

Could Blackmagic Support Team give us an explaination about this? Thanks.

no . its 4 cards on one board .. so u can use 4 inputs , 3in + 1 out, 2in + 2out , 1in + 3out or 4 outputs .. one declink card can only INPUT or OUTPUT ..

Pthkin, We have a try and successed, Thanks for your help.
