AT&T did this for Uverse - it’s unicast for 5 seconds then it switches over to multicast. I assume there’s some key frames and h26x codec configuration that’s necessary.
Unfortunately multicast doesn’t work across the internet. It’s typically filtered or ignored I think.
- sofaofthedamned 8y agoThat's correct. The unicast is there to catch up to the next multicast key frame and reduces the channel hop lag.
- tinus_hn 8y agoMulticast works great across the internet but it fails because everyone uses NAT in their home.
- isostatic 8y agoThere's issues with wifi from memory. Not sure why multicast wouldn't work from behind nat, assuming the router supported it.
