Not sure I understand the point of this. Is it to lessen loads from the distributing servers or the actual broadcaster? I can't see how this would help a broadcaster at least.
Network costs I am assuming. Wonder how bad the latency is going be though?
It doesn't really matter all that much if some viewers of a live stream are ~30-60s behind others. Heck, ESPN's online offerings can have 2-3minutes of lag. As long as this isn't used for real-time chat / video conferencing, there's really no need for super low latency
Well real-time is often not a requirement like radio talk show there's often a 7-10 seconds delay before next audio is emitted (usually to beep on inapprioiate lanuage) But being able to have most viewers watching the same frame almost simultaneously would be awesome.
But what about spot betting during a sports game?
It uses HLS or DASH so the latency should be no worse than through a CDN since those systems are already quite delayed compared to RTSP or some other more immediate protocol
