Abstract

An improved portable media device and methods for operating a media device are disclosed. According to one aspect, the portable media device can also function as a solid-state drive for data storage. The form factor of the portable media device can be hand-held or smaller, such that it is highly portable. The portable media device can use one or more status indicators. The portable media device can also include a peripheral bus connector, a rechargeable battery, and one or more input devices. According to another aspect, the portable media device has the capability to store media device status information in persistent memory before powering down. Thereafter, when the portable media device is again powered up, the stored media player status information can be retrieved and utilized. According to still another aspect, the portable media device can form and/or traverse a media asset playlist in an efficient manner.

Claims

1. A method for playing a plurality of media assets by a media asset player, comprising:

playing a media asset by the media asset player of a first playlist corresponding to a first playback mode;

receiving a first command to change a playback mode of the media asset player from the first playback mode to a second playback mode different from the first playback mode;

determining whether a second playlist corresponding to the second playback mode has been previously played; and

playing a media asset of a third playlist corresponding to the second playback mode after playback of the media asset of the first playlist is complete when it is determined that the second playlist has been previously played, otherwise playing a media asset of the second playlist after playback of the media asset of the first playlist is complete.

2. The method as recited in claim 1, wherein the first playback mode is a continuous playback mode and the second playback mode is a shuffle playback mode.

3. The method as recited in claim 2, wherein the second playlist comprises a randomly ordered listing of the media assets contained in the first playlist, and wherein the third playlist has a different order than the second playlist.

4. The method as recited in claim 2, further comprising:

receiving a second command to change the operation of the media asset player from the shuffle playback mode to the continuous playback mode;

returning to the first playlist associated with the continuous playback mode from a playlist corresponding to the shuffle playback mode;

continuing to play a currently selected media asset by the media asset player;

setting a state variable associated with the playlist corresponding to the shuffle playback mode to a value that indicates the currently selected playlist has already been played, thereby preventing reuse of the currently selected playlist;

retrieving another media asset, the other media asset being a media asset following the currently selected media asset in the first playlist; and

playing the retrieved other media asset.

5. The method as recited in claim 2, further comprising:

receiving a command to power down the media asset player during playback of the second media asset;

saving values for state variables to a location in persistent memory of the media player, the state variables comprising;

a playlist pointer, a media asset pointer, and a media asset position;

powering down the media player;

receiving a command to power up the media player;

loading the saved state variable values; and

resuming playback of the second asset at a point in the second media asset that was being played when the command to power down was received by referencing the loaded, saved state variable values.

6. The method as recited in claim 5, wherein the state variables further comprise:

volume level;

pause status; and

playlist validity indicator.

7. A method for playing a plurality of media assets, comprising:

playing a first media asset by a media asset player, the first media asset being a member of a first playlist, the first playlist being in accordance with a continuous playback mode;

receiving a first command to change a playback mode of the media asset player from the continuous playback mode to a shuffle playback mode;

continuing to play the first media asset by the media asset player;

playing a second media asset only once the first media asset has finished playing, wherein the second media asset is a member of a second playlist in accordance with the shuffle playback mode, the second media asset following the first media asset on the second playlist;

receiving a second command to change the playback mode of the media asset player from the shuffle playback mode to the continuous playback mode; and

playing a third media asset only after the second media asset has finished playing, wherein the third media asset is a member of the first playlist, the third media asset following the second media asset on the first playlist.

8. The method as recited in claim 7, further comprising:

receiving a third command to power down the media asset player;

saving a plurality of state variables associated with the playback state of the media asset player, the plurality of variables comprising;

a playlist pointer,

a media asset pointer,

a media asset position,

volume level,

pause status, and

playlist validity indicator; and

loading the plurality of saved state variables after receiving a command to power up the media asset player,

wherein the loading of the plurality of saved state variables allows playback of the media assets loaded on the media asset player to resume as with exactly the same characteristics present when the second command was received.

9. The method as recited in claim 8, wherein the playlist pointer indicates which playlist is active, the media asset pointer indicates which media asset in the active playlist is being played back, and the media asset position indicates which portion of the active media asset is being played back.

10. The method as recited in claim 9, wherein the playlist validity indicator indicates whether a new shuffle playlist needs to be generated the next time the shuffle playback mode is selected, and the pause status indicates whether or not a media asset was being played back when the media asset player was powered down.

11. The method as recited in claim 7, wherein the first playlist can only be modified by coupling the media asset player to a computer.

12. The method as recited in claim 7, further comprising:

subsequent to receiving the first command to change the playback mode from the continuous mode to the shuffle mode, determining whether the second playlist has already been played.

13. The method as recited in claim 12, further comprising:

when the second playlist is determined to have already been played, generating a third playlist that is a randomized version of the first playlist, the media items of the third playlist arranged in a different order than the second playlist and the first playlist; and

playing back a second media asset that follows the first media asset in the third playlist.

14. The method as recited in claim 7, further comprising:

receiving an input directing generation of a new shuffle playlist when the media asset player is in the shuffle mode;

generating a new shuffle playlist;

halting playback of any currently playing media asset; and

beginning playback of a first media asset on the newly generated shuffle playlist.

15. A method for playing a plurality of media assets by a media asset player, comprising:

playing a media asset by the media asset player when the media asset player is configured to operate in accordance with a first playback mode;

receiving a first command to change the operation of the media asset player from the first playback mode to a second playback mode different from the first playback mode;

determining whether a first playlist associated with the second playback mode has been played;

when it is determined that the existing playlist has been played, operating the media asset player in accordance with a second playlist in accordance with the second playback mode only after playback of the media asset associated with the first playback mode is complete, wherein the second playlist is different than the first playlist; and

when it is determined that the first playlist has not been played, operating the media asset player in accordance with the first playlist only after playback of the media asset is complete.

16. The method as recited in claim 15, wherein the first playback mode is a continuous playback mode and the second playback mode is a shuffle playback mode.

17. The method as recited in claim 15, wherein the second playlist is generated only when the first playlist is determined to already have been played.
