Abstract

A portable device has a storage medium for storing media content such as audio and video files. The portable device can communicate with an external media player or network when it is connected to the player or situated near the player. The external media player allows a user to select items of media content for presentation. Each time a user selects a new item of media content for presentation on the external media player, a copy of the selected media content is automatically transferred to the storage medium on the portable device. Thus, when the user removes the portable device from the external media player, the user has a history of his/her recent selections as well as copies of his/her recent selections stored on the portable device.
