"Although Apple has previously dismissed deals with satellite radio providers, it continues to explore the technology on its own, as discovered in a recent patent application by the company. The filing, published October 19th and originally filed in August 2005, refers to two distinct methods of integrating the iPod with satellite services. The first aspect of the patent describes the ability to tune "into a wireless signal (e.g., AM FM radio, digital radio, or WiFi)" using an iPod-style player with "the capability to accept accessories to add the necessary functionality." While this may refer to Apple's Radio Remote released late in 2005, the patent's explicit mention of support well beyond AM/FM radio is significant and may signal a future add-on that would supply satellite radio directly to the iPod," Electronista reports.

"More important still is the description of how such accessories would share information between the iPod and external receivers. In another section of the patent application, Apple refers to an "in-vehicle receiver-player" that would connect to both a music player and an in-car network and synchronize track data between the two connected devices," Electronista reports.
