VOD = video on demand, unicast is good. Live = stream, multicast is good. The 1.5 second multicast estimate for next Olympics from BBC sounds reasonable based on my experience working with signalling and now live straming systems. Good read around the steps and impact around buffering introducing delay. My programmer brain said “sounds like the receiver should control flow into its encoder”... so is it that it’s too conservative a buffer, or the encoding algorighms actually need that much buffer to get economy?
