That's how radio works now, it's owned by like 3 companies. Automation/playout for large groups of stations is all centralized, and they carry the baseband over IP to transmitter. Radio solved it awhile ago.

Stereo pair, pilot, RDS (the scrolling artist/song text), and the 67 kHz SCA. It's not quite 192kHz as I recall, but that's nearest fit really. AES192/192kHz MPX composite on the back end of every exciter/transmitter when I was last near them.

Good old FM radio (in stereo) is a 192kHz mux, annoyingly.
