 Yiu Lee:

Many people who I asked about live feeds, said the live feeds were often shifted 5-20 minutes and then done as normal video streaming.

Is this true? 

Thanks, and If I don't hear from you.. Merry Christmas,

Sue

For OTT providers, unicast is the current option to deliver live content because inter-domain multicast is uncommon. Speaking of trend, using unicast for broadcasting is inefficient IMHO, so I don't see why using http to deliver live content is the trend.

My 2 cents.
