RELATED APPLICATIONS 
       [0001]    This application claims priority from U.S. provisional application Ser. No. 60/407,174, filed Aug. 30, 2002, incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to media player systems. 
       BACKGROUND 
       [0003]    Media players such as digital music players and multimedia players have been introduced. Some of these players permit a user to transfer media, under control of a host computer operated by a user, between the player and the host computer, which might be networked. In this way, media titles that are available on the network can be conveniently transferred to the media player. 
         [0004]    To manage the above-mentioned operations, control software is executed on the host computer. The control software is operated by a user at the host computer to present a graphical user interface (GUI) on the host computer, to facilitate, e.g., browsing for media titles and controlling the transfer of titles to the player. 
         [0005]    As recognized by the present invention, the process discussed above requires a user to access the host computer, and to know how to operate the host computer. As further recognized by the present invention, it would be advantageous to permit the user to manage media transfer using the player itself, without requiring the player to have a relatively expensive processor capable of executing the operating software. 
       SUMMARY OF THE INVENTION 
       [0006]    A system for managing media distribution includes a host computer and a media player that includes a display and at least one input device. The media player communicates with the host computer. A software-implemented control module in the host computer renders a user interface (UI) on the player, such that a user can manipulate the input device in cooperation with the UI to manage distribution of media between the host computer and player. 
         [0007]    In a preferred embodiment, the user can manipulate the input device to cause the host computer to transfer a media stream to the player. The preferred input device may include one or more buttons on the player and, if desired, a jog dial, and a media stream can be downloaded to the player in response to the user depressing the button once and only once, without requiring the user to depress any other buttons. Also, the preferred player may include at least one light emitting diode (LED) and the host computer can energize the LED to indicate to the user the availability of a music title. 
         [0008]    In other preferred, non-limiting embodiments, the host computer can periodically poll the player to determine player status. Preferably, the host computer polls the player more frequently when the player is in an active mode than when the player is in an energy-saving mode. The player may not be able to initiate communication with the host computer. 
         [0009]    In another aspect, a method for providing at least one media stream to a media player includes engaging a data storage disk with a medium device to establish an engagement, and detecting the engagement. Using the host computer, an indication of the engagement is caused to be displayed on the media player. The method also includes manipulating a single button a single time on the media player to cause a media stream on the disk to be sent to the media player under control of the host computer. 
         [0010]    In still another aspect, a media player includes electronic media storing at least one media stream, and means for playing the stream. A display for presenting a user interface (UI) generated by a host computer and transmitted from the host computer to the media player is also provided. 
         [0011]    The details of the present invention, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0016]    Referring initially to  FIG. 1 , a system is shown, generally designated  10 , that includes a portable media player  12 , such as a music player, e.g., a Sony Walkman® or other multimedia player with data storage capabilities, such as a Sony Memory Stick®, for storing digitally recorded songs and the like. The media player  12  also includes a play device that reads electronically stored streams on the data storage and transforms the streams into audible sounds in accordance with media stream playing principles known in the art, such as those embodied in a Sony Walkman®. The media player  12  can be a CD player. 
         [0017]    The media player  12  can include a processor  14  and a display  16 , such as an LCD display, but unlike a personal computer, the processor  14  does not generate a graphics user interface (GUI) on the display  16  when undertaking the media management operations discussed below. By “GUI” or “UI” is meant the actual graphical elements necessary for control using a display, as opposed to data elements, such as media titles, that are displayed using an underlying GUI. In a less preferred embodiment, no display need be provided, only the below-described LEDs to indicate status. 
         [0018]    The media player  12  can also include a user input device  18 , such as but not limited to buttons and/or jog dials. In one preferred non-limiting embodiment, the media player  12  includes a housing that can be worn on the belt of a person and headphones connected by a wire to the housing, with the display  16  and input device  18  (in the form of buttons and jog dial) being attached to the headphone wire, although all the components of the player  12  can be mounted on a single housing if desired. If desired, non-graphic indicators such as LEDs  20  (three shown) can be provided on the belt-worn portion of the player  12  for purposes to be shortly disclosed. 
         [0019]    As shown in  FIG. 1 , the system  10  includes a host computer  22  that communicates with the media player  12  via a communication path  24 . The path  24  can be a wire that uses a universal serial bus (USB) protocol, or a IEEE 1394 protocol, or a RS-232 protocol, or a 802.11 protocol. Or, the path  24  can be a short range wireless path such as Bluetooth, infrared, or other wireless path. The host computer  22  can be a personal computer or other computer associated with the user that executes a media management control module  26  in accordance with the logic below. 
         [0020]      FIG. 1  also shows that one or more networked devices  28  can be connected to the host computer  22  either directly or through the Internet  20 . If desired, a networked device  28  can be connected directly to the player  12 . The networked devices  28  can be, without limitation, CD and DVD players that can receive, e.g., CD-ROMs on which music or other sound is recorded, and other computers. One of the networked devices  28  may be an Internet-accessible or otherwise accessible electronic music distribution server. 
         [0021]    Now referring to  FIG. 2 , the overall logic of the present invention can be seen. Commencing at block  32 , communication is established between the host computer  22  and the player  12 . In some embodiments the player  12  cannot initiate communication, so that the host computer  22  initiates the link at block  32 . 
         [0022]    Moving to block  34 , the control software  26  in the host computer  22  downloads a GUI to the player  12  for display thereof on the display  16 . The GUI can, without limitation, indicate and support operations that may be executed by the host computer  22  in response to user input at the player  12 , as well as provide the necessary control means that enable the user to issue commands to cause the host computer  22  to execute the operations. 
         [0023]    In any case, the processor  14  of the player  12  need not generate the GUI or even know how it functions. This makes the player  12  very robust, in that additional functionality can be provided simply by appropriately programming the host computer  22  without having to modify the relatively simple and inexpensive player  12 . 
         [0024]    At block  36 , user commands generated by appropriately manipulating the input device  18  on the player  12  in conjunction with the GUI are received by the host computer  22 . These commands represent user management desires, e.g., a command to copy a stream from one of the devices on the network, such as all or part of the content of a CD player network device  28 , to another, such as the player  12 . The commands can also indicate updating the player display to allow the user to navigate through the menus. The commands from the player  12  are executed by the host computer  22  at block  38 . 
         [0025]      FIG. 3  shows an exemplary one-click copy operation in accordance with the present invention. Commencing at block  40 , a user can engage a disk such as a CD or DVD with an appropriately configured network device  28 . The host computer  22  detects the engagement by, e.g., receiving a message indicative of the engagement from the network device  28 . 
         [0026]    At block  42 , the host computer renders an indication on the player  12  that the disk has been engaged with the network device  28  and that digitally recorded streams, such as music or multimedia streams, are available for recording into the player  12 . A menu showing the available artists, and/or albums, and/or tracks, can be displayed. Without limitation, the indication can include one or more of the following: energizing the LED  20 , displaying the titles of available streams on the display  16 , and displaying a message on the display such as “copy disk?” 
         [0027]    Moving to block  44 , the user manipulates the input device  18  as appropriate to input the desired command(s). In one preferred embodiment, the input device  18  includes a button, and the user simply depresses the button once and only once to cause the host processor to provide the player  12  with a copy of the available stream or streams—i.e., one-click copying. No other user action is required, either at the player  12 , host computer  22 , or network device  28 . Instead, at block  46  the control software of the host computer  22 , responsive to the command input at the player  12 , executes the command, in this case, by causing a copy of the available stream on the disk that was engaged at block  40  to be sent to the player  12 . 
         [0028]    In another embodiment, the user of the player  12  may scroll through a list of titles presented on the GUI using the jog dial of the input device  18 . When the desired title is displayed, the user may depress a button of the input device  18  to receive a copy of the stream represented by the title. Still further, the GUI generated by the host processor  22  may display a list of available artists, with the user selecting one of the artists to cause a second menu or list of songs by that artist to appear on the display  16  of the player  12 , for subsequent selection of a particular song or songs by that artist. 
         [0029]      FIG. 4  shows logic that can be executed to copy content to the player  12 . While the logic is shown in flow chart form with decision diamonds for convenience of disclosure, it is to be understood that the logic equivalently could be represented by a state diagram or other logic indicating convention. 
         [0030]    Commencing at block  48 , a command from the host computer  22  is monitored for. Decision diamond  50  indicates that the command, when received, might be a command to render the GUI on the display  16  or energize an LED, in which case the logic moves to block  52  to render the GUI and/or energize the LED. Decision diamond  54 , on the other hand, indicates that the command may be a status request, in which case the logic moves to block  56  to communicate the status of the player  12  back to the host computer  22 . In one preferred non-limiting embodiment, to conserve energy the player  12  has an energy saving mode and an active mode. In the energy saving mode, the player  12  is quiescent, to conserve energy. When this status is reported to the host computer  22 , it issues status checks to the player  12  less frequently than it does when the player  12  is in the active mode, i.e., is being used to play a media stream. The user may exit the energy saving mode at any time by, e.g., depressing a button on the input device  18 . 
         [0031]    Block  58  indicates that if the processor  14  determines that a command has been received but that it is not from the host computer  22 , it must be a device-specific command (such as “play track”) that is executed locally. 
         [0032]    While the particular REMOTE USER INTERFACE FOR MEDIA PLAYER as herein shown and described in detail is fully capable of attaining the above-described objects of the invention, it is to be understood that it is the presently preferred embodiment of the present invention and is thus representative of the subject matter which is broadly contemplated by the present invention, that the scope of the present invention fully encompasses other embodiments which may become obvious to those skilled in the art, and that the scope of the present invention is accordingly to be limited by nothing other than the appended claims, in which reference to an element in the singular is not intended to mean “one and only one” unless explicitly so stated, but rather “one or more”. All structural and functional equivalents to the elements of the above-described preferred embodiment that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the present claims. Moreover, it is not necessary for a device or method to address each and every problem sought to be solved by the present invention, for it to be encompassed by the present claims. Furthermore, no element, component, or method step in the present disclosure is intended to be dedicated to the public regardless of whether the element, component, or method step is explicitly recited in the claims. No claim element herein is to be construed under the provisions of 35 U.S.C. §112, sixth paragraph, unless the element is expressly recited using the phrase “means for” or, in the case of a method claim, the element is recited as a “step” instead of an “act”.
