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.
That's for the FM baseband signal, not the audio. Among other things you're doing here, you're basically treating a stereo signal (plus a pilot that effectively contains no information, plus an extremely low bitrate RDS stream in an extremely inefficient way) as one monaural signal.
But maybe there's a use case for replacing an AES192 signal carrying the full FM baseband signal over ETH-67? I'm not sure it's the correct fit, though.
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.
How so?
