ABSTRACT:
A portable media device intelligently caches media based on device state. The portable media device has a hard disk memory to store the media (e.g., music, videos, movies, games, etc.) and a cache memory. When the device is in a state of user interaction (e.g., the user is navigating a menu or playlist, the user interface is unlocked, and so forth), the portable media device caches many snippets of different media items in a playlist. This enables the device to respond quickly to user input and provide instant playback as the user navigates items in the playlist. Conversely, when the device is in a playback state (e.g., the user has ceased interacting with the device for a period of time, or has locked the user interface), the portable media device caches as much contiguous data from the selected media item in the playlist as possible.
