System and method for obtaining media content for a portable media player
First Claim
1. A portable media player comprising:
- a local wireless communication interface that communicatively couples the portable media player to a secondary system within a local wireless coverage area of the portable media player;
a digital storage device that stores a copy of one or more media files from a media collection of a user of the portable media player and proxy information representing each of a plurality of media files from the media collection, wherein the plurality of media files represented by the proxy information comprises media files from the media collection for which copies are not stored in the digital storage device, the media collection of the user stored on an associated user system; and
a control system associated with the local wireless communication interface and the digital storage device that;
provides the proxy information to the secondary system for one of a group consisting of;
at least one of the plurality of media files programmatically selected based on at least one criterion and all of the plurality of media files;
receives a notification from the secondary system of a matching media file stored by the secondary system, the matching media file identified by the secondary system based on the proxy information provided to the secondary system; and
performs an action in response to the notification from the secondary system wherein the plurality of media files represented by the proxy information comprises media files from the media collection selected by the associated user system based on at least one criterion.

Abstract
A system and method are provided for enabling a portable media player to obtain media content from secondary systems, such as other portable media players, via local wireless communication. In general, the portable media player stores proxy information identifying the media content of a number of media files in the user'"'"'s media collection rather than the media files themselves. When a secondary system is within a local wireless coverage area of the portable media player, the proxy information for the media files, or a subset thereof, is provided to the secondary system. In response, the secondary system identifies media files stored by the secondary system having media content matching the media content identified by the proxy information. The secondary system then provides a notification of the identified media files to the portable media player, which may then obtain the identified media files from the secondary system.
