Virtualized air chains extend broadcast virtualization into transmission

If the air chain moves into the same virtualization model as the rest of broadcast, it would extend software-based infrastructure from playout deeper into transmission. That matters because the article treats the air chain as the remaining link in an increasingly virtualized broadcast stack. For vendors and operators, the competitive question is whether transmission-side workflows get brought into the same architecture as other broadcast functions. The concrete signal to watch is whether the industry starts describing the air chain as a virtualized sequence from content playout to transmission, rather than a hardware-bound one.
