[IRCA] HD Surround Sound?

["W. Curt Deegan" <WWWR@xxxxxxxxxxxxx>]

While enjoying commercial free oldies on XM the other night, a brief 
technology update item by "Lazlo"(?) spoke about Surround Sound now on some 
FM and AM IBOC stations -- or HD as he called it.

What is this all about?  Or has he just convoluted his concepts?  He said 
surround sound more than once.

I have to wonder if someone is now using the term "surround sound" to mean 
something altogether different than what it really does.

Maybe with proper Dolby processing equipment the received hiss can be 
isolated on back channels and sold as surround.  A new slogan for IBOC: 
"Soothing white noise to augment your listening experience."

Anyone know what this latest IBOCism is about?
