DIGITAL RADIO TAGGING USING AN RF TUNER ACCESSORY

摘要

An accessory having an RF tuner for digital radio, such as HD radio, can be in communication with a media player such as a portable media device (“PMD”). The user can be given the ability to command the accessory to provide raw digital data, the ability to scan only for stations having digital audio content (or for all available stations), the ability to provide station lists of stations having digital audio content (or all available stations), and the ability to request and store metadata beyond that for stations actually being listened to provide enhanced search capabilities. Enhanced metadata and searching can provide the listener the ability to refine station choices without having to listen at length to any particular station, and further can facilitate tagging broadcast tracks for subsequent access and/or purchase.
