Reducing latency to as near zero as possible is the holy grail of IP delivered TV. The problem is that live TV pictures have to be compressed prior to transmission. The time required to compress the image causes the latency. If you’re broadcasting live via Facebook (which our church has been doing every Sunday during lockdown) the Facebook live broadcast service allows you to select how much latency you want to tolerate. They advise you to go for a higher figure unless you need near-real-time responses from your viewers. If you opt for a lower figure, the trade off is reduced video quality. Obviously that’s not acceptable for premium live sports where they want to have their cake and eat it. I believe the BBC has been working on its own proprietary technology in this area as well.
