Description:
This application is a continuation of co-pending U.S. patent application Ser. No. 14/939,891 filed Nov. 12, 2015, which is a continuation of U.S. patent application Ser. No. 12/790,623, filed on May 28, 2010, now issued as U.S. Pat. No. 9,213,391. 
    
    
     BACKGROUND 
     Today, many popular electronic devices, such as hand-held media players or portable electronic devices (“PEDs”), are battery powered and include various user interface components. Conventionally, such electronic devices include buttons, dials, or touchpads to control the media devices and to allow users to navigate through media assets, including, for example, music, speech, or other audio, movies, photographs, interactive art, text, and media resident on (or accessible through) the media devices, to select media assets to be played or displayed, and/or to set user preferences for use by the media devices. The functionality supported by such electronic devices is increasing even as these media devices continue to get smaller and more portable. Consequently, as such devices get smaller while supporting robust functionality, there are increasing difficulties in providing adequate user interfaces for the portable electronic devices. 
     Further, as users continue to rely more heavily on these devices for running media applications, battery life and reliability become increasingly important. As devices become smaller and more portable, however, battery size and capacity often also decreases, sometimes leaving users unable to use their media devices as often as they would like to. 
     Additionally, different portable electronic devices may include different interfaces and functional capabilities, and smaller devices do not always include the full functionality that their larger counterparts may offer. For example, while a smaller device may be more portable and lightweight than its larger counterpart, it may not have circuitry available capable of adjusting media playlists or creating new media playlists “on-the go”, while a larger and more complex device might have these and other capabilities not associated with the smaller device. 
     Systems and methods in accordance with the disclosed subject matter integrate multiple electronic devices to increase the functionality of these devices individually and to address the previously mentioned issues. The disclosed subject matter includes systems and methods that take advantage of the capabilities of individual electronic devices and among other things, address the battery life, interface and interactivity issues discussed above. 
     SUMMARY 
     An electronic device can be coupled to another electronic device. The first electronic device can act a processor device, and the second electronic device can act as a media player device. After the devices are coupled, the user interface of the processor device can be used to control media playback on the media player device. Additionally, the power supply of the processor device can be used to charge the power supply of the media player device, even while the power supply of the media player device is being used to control media playback using circuitry on the media player device. The processor device can also be used to create and edit media playlists which can then be stored on the media player device. 
     To control media playback, the processor device can receive metadata associated with media stored on the media player device and identify information related to this media. The processor device can then open a user interface that a user can interact with, using it to control various aspects of media playback, such as playback volume and playback order. 
     In some embodiments, the processor device can be used to create or generate media playlists for the media player device. For example, after reading metadata received from the media player device, the processing device can display a list of media stored on the second device, and a user can use a media player user interface to select specific media to be played. The list can also be sent back to the media player and saved there for future use. A user is not limited to generating a single playlist, but can chose to generate multiple playlists of various lengths, if he so chooses, which can all be stored on the media player device. 
     In some embodiments, the power supply of the processor device can be used to charge the power supply of the media player device, even while the power supply of the media player device is being used to control media playback using circuitry on the media player device itself. If the user wishes, in certain embodiments, the media player device can be unplugged from the processor device and continue operating, effectively treating the processor device similar to a portable power supply charger.

Display data for the media player may be sent from the media player device to the processor device. The processor device may contain hardware and software configured to import the media player&#39;s native user interface and show the interface on its own device display. In other embodiments, the processor device may show an interface that is not native to either the processor device or the media player. As shown in status display banner  350 , in these embodiments, the display may include an indicator letting a user know that the processing device is being used to control the media player. In certain embodiments, after the processor device and the media player device are coupled, the processor device may display a menu presenting interface options for the user to choose from. The user may choose from displays native to the processor device or media player, a preloaded non-native interface or in some embodiments, may generate a new custom user interface. 
       FIG. 4  is a flowchart of an illustrative process for coupling a first electronic device to a second electronic device and using the first electronic device to control playback circuitry on the second electronic device in accordance with one embodiment of the disclosed subject matter. In block  410 , a first electronic device and a second electronic device are coupled. The first electronic device may be similar to electronic processor device  210  of  FIG. 2 . The second electronic device may be similar to media player device  230  of  FIG. 2 . The devices may be coupled using a connector similar to coupling device  250  in  FIG. 2 . Various types of coupling devices can be used to couple the two devices. For example, coupling can be performed using a USB cable, a firewire cable, or via audio input/output jacks. In certain embodiments, the devices may be coupled wirelessly. In block  420  after the two devices are coupled, the interface of the first electronic device can be used to control the playback circuitry of the second electronic device. In block  430 , the interface is powered using the power supply of the first electronic device. In block  440 , the playback circuitry is powered using power supply of the second electronic device. 
       FIG. 5  is a flowchart of an illustrative process for coupling a first electronic device to a second electronic device and using the first electronic device to control media playback on the second electronic device in accordance with one embodiment of the disclosed subject matter. In block  510 , a first electronic device and a second electronic device are coupled. The first electronic device may be similar to electronic processor device  210  of  FIG. 2 . The second electronic device may be similar to media player device  230  of  FIG. 2 . The devices may be coupled using a connector similar to coupling device  250  in  FIG. 2 . Various types of coupling devices can be used to couple the two devices. For example, coupling can be performed using a USB cable, a firewire cable, or via audio input/output jacks. In certain embodiments, the devices may be coupled wirelessly. In block  520 , after the two devices are coupled, the electronic processor device power supply begins charging the media player power supply via the coupling. Charging can continue even while the media player power supply is being used to supply power to media play circuitry for media playback or other applications using the media player device. In block  530 , the two devices exchange data via their physical or wireless coupling. In an exemplary embodiment, the media player device sends metadata related to media files stored on the media player to the electronic processor device. The metadata sent from the media player device to the electronic processor device can be associated with media content using any suitable approach. For example, metadata can be stored as part of data that includes the content (e.g., metadata forms a header in a file). As another example, metadata can be stored in a separate location from the content. In particular, metadata can be stored in a metadata file (e.g., one file for each instance of content), a database (e.g., metadata database within an electronic device or within a particular application), remote location (e.g., a remote server), or any other suitable location. If the metadata is stored separately from the content, the metadata can be associated with the content using any suitable approach, including for example one or more references in the metadata and/or content, pointers, links, or other combinations of these. 
     In block  540  after receiving metadata, the electronic processor device can display a list of media stored on the media player device on its own user interface display. Depending on the embodiment and the received metadata, the electronic processor device can display a list of all the media stored on the media player device or can display only a certain subset of the stored media. In block  550 , a subset of the displayed media is selected for playback on the media player device. Among other things, the user interface can also be used to forward through media, rewind media, pause media playback and adjust playback volume, create new media playlists or edit already existing media playlists. 
     The interface may also be used to shuffle media in a “random” order, set a single media item to repeat, or set a larger set of media to repeat after cycling through at least once. After a user makes the appropriate selection, the electronic processor device sends command data to the media player device, which then translates the command data and responds accordingly with its playback circuitry. Depending on user preferences, either the entire set or a smaller subset of the displayed media may be selected for playback on the media device. In certain embodiments in accordance with the disclosed subject matter, the media player device can continue playback even after the electronic processor device is decoupled. 
     Embodiments of the disclosed subject matter can also be embodied as computer readable code on a computer readable medium. The computer readable medium is any data storage device that can store data which can thereafter be read by a computer system. Examples of the computer readable medium include read-only memory, random-access memory, CD-ROMs, DVDs, magnetic tape, and optical data storage devices. The computer readable medium can also be distributed over network-coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. 
     Although many of the embodiments of the presently disclosed subject matter are described herein with respect to personal computing devices, it should be understood that the presently disclosed subject matter is not limited to personal computing applications, but is generally applicable to other applications.
