I’ve seen stuff going to and back from AWS with sub second latency, even with h264 encoding. BT sport have operated remote production channels from AWS for a few years now [0] I’m no fan of cloud, but the latency to a nearby DC isn’t high, and when your feeds are going from the field anyway it doesn’t make much difference. I remember OBS (the Olympics, not the open source software) bemoaning the lack of bandwidth available in cities and them having to build data centres in place like Beijing for temporary events, because there simply isn’t the multi-bit links to AWS etc available.

The hardware AWS would be using, NICs etc do have the level of DMI needed for the latency.
Heres the catch though, the workflow I described can be done with maybe 2 frames of latency for like 400usd, and you own the hardware . I wouldn’t be surprised if some of AWS products are 400usd per hour.
You can setup a very competent broadcast system for not much money and use some actual cots hardware and still have significantly less latency that a second, probably in the low single digit frames.
I don’t the solution proposed by matrox isn’t possible, I just think for most use cases it is very expensive both in actual cash and in latency.
