Synchronizing Content from Removable Digital Media

To analyze and present metadata, such as song title or artist, a multimedia system uses metadata synchronization. This paper explores several synchronization techniques,and examines techniques for synchronizing metadata from iPods, using either the traditional iPod Access Protocol over serial/USB links, or the newer authentication IC approach. Finally, this paper discusses techniques of data persistence, with a focus on managing the reinsertion of previously inserted media.
