Nice!

I am a bit skeptical about "down to about 1 second" being achievable with DASH or LL-HLS reliably. Of course, I could be wrong. And a lot depends on the definitions of "about" and "reliably," as well as your user cohort (where they are in the world, etc). :-)

The reason I didn't write much about DASH is that the basic concepts are the same for both DASH and HLS. And my sense for the last couple of years has been that most of the momentum in the ecosystem as taking place around HLS/LL-HLS. But I could be wrong about that, too.

In some areas of the world where network and/or device performance are limited such a low latency will be impossible to achieve indeed. Inter regional broadcasting also comes with a latency penalty, but with good CDNs like provided by our partner Akamai you can already get a 1 second latency in many cases. That being said the buffers will be very small and we don't recommend using that yet in general.

HLS and DASH are similar indeed, but I think the main reason that HLS is still used a lot is that it's the lowest common denominator; you can get it to work everywhere. Perhaps in the future that will be LL-HLS, or something else entirely, but for now most really low latency broadcasting that I'm aware of is using DASH with HLS as a fallback (i.e: CMAF). But I could also be wrong about that of course :-)
