NPR currently uses NTP to synchronize the local broadcast time to the 
satellite feed. The crucial issue is to encapsulate the compressed audio 
in IP packets, not the other way around. I suspect PBS might do the same 
thing as well, as their programs start time deltas are be in the low 
milliseconds relative to UTC. The DRM page cited is riddled with errors. 
Somebody (me?) should send a comprehensive bug report.
