HE-ACC + SBR is the codec used in Hybrid Digital Radio, Digital Radio
Mondiale, and DAB+.

1) The ACC is an athletic conference within the NCAA. You mean AAC.

2) There is no such thing as "Hybrid Digital" radio. "HD Radio" is a
trademark of iBiquity Digital Corp for their IBOC implementation, and
the "HD" doesn't mean anything in particular. IBOC has three modes of
operation: hybrid, extended hybrid, and all digital. All three are
part of "HD Radio."

3) "HD Radio" uses a codec known as HDC (a.k.a. "HD Codec"). While
iBiquity has acknowledged that it uses SBR, they have pointedly
declined to discuss whether or not it has any other similarity to HE-
AAC. I doubt that you could cite an authoritative source, but if you
could I would love to know about it.
