Google is your friend:

Basically there's a digital component added to the analog.  A HD radio
picks up the digital signal, and much like a TCP/IP stream can sort packets
that don't arrive in strict order, sorts them out into a signal without 
static, hiss or pops.

The record labels are still going to insist that recordings be compressed
to within an inch of listenability.
