The current plan is to stream from an ATEM unit to our editing PC and then use a Decklink card to capture the stream and output it to BNC to broadcast. I'm hoping someone can confirm that a Decklink card, such as the Mini Monitor or SDI, would work for this.
Thanks
Just checking I have this fully understood. It might just be a matter of "terminology".
Stream is usually used these days to mean Stream to the web (e.g. Livestream /Ustream... any other type of stream).
I think when you use the term Stream you are really just saying input/output a video signal.
The output from the ATEM TVS will be either HDMI and/or HD-SDI or SD-SDI or in the case of the ATEM 1ME or 2ME - you also get simultaneous SD-SDI and Component and SD Composite (BNC) output
Now... as for "Capture" yes a decklink card will work great for that - just be aware of the data needs relevant to the video format you will be capturing in and make sure your hard drive/system is capable.
But it's not clear to me what you mean by "
capture and stream the output to BNC to broadcast".
BNC is merely a connector type. The video standard used could be SD Composite, SD-SDI or HD-SDI - as all of them us a BNC type connector.
What video format do you need to broadcast?
The Decklink card could likely be used to connect to that BNC "for broadcast"... but the ATEM may be able to directly connect to your broadcast system depending on the format used.
Just a general comment/recommendation I think you would likely be better off at a minimum with the ATEM 1ME for the additional output formats and additional keying/DVE capabilities that the TVS does not have.
