Abstract

Disclosed are a device and method for securely storing and organizing SDARS content on a portable player. SDARS audio content is stored on a private partition of the device not available to a client PC. Shadow files are stored on a public partition of the device. The shadow files contain metadata related to the corresponding SDARS audio and a reference to the SDARS audio on the private partition. Playlists can be organized on the device intermixing stored SDARS content with DRM and non-DRM protected media content. Downloading of purchased or subscription-based media files based on observed or received SDARS content is facilitated. Digital Rights Management features are included to control authorized actions with respect to SDARS content. Firmware updates are performed using encrypted firmware unique to the particular device to thwart firmware hacking.
