Challenges are mostly around keeping lock-step timing across a lot of separate devices in the system at scale (using PTP) for frame-accurate switching, and working through getting the SMPTE-2110 standards completed for interop, but there huge benefits on ability to scale to well beyond what is practical with coax, as well as cost savings on cabling with more density (and weight savings, for mobile production trucks which is important). There are also big architectural advantages of having more dynamic infrastructure and device discovery (AMWA NMOS, etc) rather than hard-wired coax signal paths. There are a lot of scenarios with massive scale on the back-end, with lots of streams managed as part of the production process ahead of delivery to consumers... We have an IP video router (https://evertz.com/products/EXE-VSR https://evertz.com/products/EXE-VSR) that has 2,304 10Gbps ports (moving to 25Gbps per port), each of which can do 6x fully uncompressed SMPTE 2110 video (1080i 29.97fps) flows in each direction, with a 46Tbps non-blocking back-plane so the scale can get a bit crazy. The full scale back-end stuff is pretty invisible from the consumer side. Eventually that internal infrastructure feeds into distribution encoders that produce lower bitrate streams for cable/sat/web distribution (for real-time events, with separate file delivery for VOD platforms like iTunes & Netflix)
