XM Satellite Radio apparently has a different take on the role of HD Radio and rebroadcast of its signal.
XM wants to transmit its signal into HD Radios. The satcaster applied for a patent in December 2005 to send its signal – as well as that of MP3s, CDs and other digital sources – via IBOC. Such a scheme would keep its signal digital throughout the entire transmission path, and eliminate the need for analog FM modulator add-ons, it says in the application published this month by the U.S. Patent and Trademark Office.
