It'd be great if it could be done using IP multicast! Sadly over the Internet to consumer devices multicast isn't an option, sometimes it is within a particular ISP for their services, but from an arbitrary broadcaster to a receiver it's all unicast (and often pull-based using HLS or DASH)
- corndoge 8y agoI meant at real scale where it makes sense. You're correct in that your upstream ISP needs to support PIM to the customer edge, which is hard to get, but available for certain customers and especially so in datacenter fabrics.
- cnorthwood 8y agoah yes, I thought you were talking about distribution rather than inside a production facility. At that case the bandwidth of uncompressed 4K (which you want to do so you're not introducing compression artifacts) is in the order of several Gbps, so bandwidth is pretty high, although multicast is used.
- monocasa 8y agoYeah, I worked on a startup to push IP multicast TV to consumers way back when. Went nowhere for the reasons you state, but we got some cool tech out of it regardless.
