"HD Radio" is the trademark for iBiquity's in-band on-channel (IBOC) technology, which was selected by the Federal Communications Commission (FCC) in 2002 as a digital audio broadcasting method for the United States.[2][3] According to iBiquity's website the "HD" is simply a brand name and has no meaning, although in its early whitepapers,[4] iBiquity used the original name "Hybrid Digital". That was later dropped. There is no connection with high-definition television (HDTV), although like HDTV the HD Radio specification provides enhanced capabilities over the old analog format, such as 5.1 surround sound.
