As mentioned in: http://tips.newtek.com/what-are-the-free-ndi-applications-and-where-do-i-get-them/
I am looking for documentation (or advice) as to how to consume and generate SMPTE 2022 with Ndi Connect Pro.

I've gone through the user's guide and could not find any instructions.
Also, I could not find any 2022 options in the output options.
All I could see were hardware outputs which list my SDI card and Skype.

My understanding is that NDI<->2022 requires a 2022 i/o card. I don't have info on a specific unit, but someone else might offer a recommendation.

Just to be clear, I have a software program that generates smpte2022 over UDP. I would like to consume this video using NDI connect. Is that not possible without additional hardware?

This is how, for example, Dante or an AES67 audio signals are supplied to Connect Pro. They don't rely on hardware, although a hardware solution would work too. But the developers of the add-on software have prepared drivers that appear as 'virtual soundcards' to Windows on (in this case) the Connect Pro system. You can't just send IP audio to the network from an external source with the result that Connect Pro will 'see' it. (I think it's possible that a 'virtual 2022 card' is a theoretical possibility, but if there is one I am not aware of it.)

My understanding is the DeltaCast card is the solution for Connect Pro to bridge to SMTPE 2022 protocol.

I'd be interested to know more about the software 2022 implementation. From what I understand, 2022-6 is so timing dependent that software implementations use a huge amount of CPU power to manage the connection.

Just a quick addition to Kane's response. I know that AJA were testing Connect Pro with their AJA Kona IP earlier this week and it does offer interchange between SMPTE 2022-6 and NDI
