     DETAILED DESCRIPTION OF THE INVENTION 
     The invention pertains to improved methods and systems that facilitate data delivery to electronic devices. One aspect pertains to data delivery to electronic devices that are portable, such as, mobile devices. In one embodiment, one mobile device discovers another mobile device within its vicinity. The mobile devices can then wirelessly transmit data from one mobile device to the other. Typically, the mobile devices are associated with persons (users). The mobile devices, or their users, can control, request or influence the particular data content being delivered. 
     The data delivery described is particularly suited for delivery of media data. “Media data,” as used herein, is digital data that pertains to at least one of audio, video, and images. Some examples of specific forms of media data (which can be referred to as “media items”) include, but are not limited to, songs, albums, audiobooks, playlists, movies, music videos, photos, computer games, podcasts, audio and/or video presentations, news reports, and sports updates. Media data is also referred to as media content herein. 
     Embodiments of the invention are discussed below with reference to  FIGS. 1-15C . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. 
     Various aspects, embodiments and implementations of data exchange are described below. These aspects, embodiments and implementations can be utilized separately or in any combination. 
     Data Exchange Environment 
     One aspect of the invention pertains to a data exchange environment. The data exchange environment facilitates exchange of data between electronic devices using wired and/or wireless means. The data exchange environment can pertain to exchange of media data, in which case the data exchange environment can be considered a media exchange environment. 
       FIG. 1  is a block diagram of a data exchange system  100  according to one embodiment of the invention. The data exchange system  100  permits data exchange between a plurality of different electronic devices. At a minimum, these electronic devices are capable of receiving and storing digital data, and may also be capable of transferring digital data. Still further, these electronic devices may also process, display, present (e.g., play) or otherwise utilize digital data. 
     The data exchange system  100  includes a central data device  102 . The central data device  102  is a central data store that stores data (i.e., digital data) that can be acquired by any of the various electronic devices within the data exchange system  100 . In particular, a personal data device A  104 , a personal data device B  106  and a personal data device C  108  are each able to couple to the central data device  102 . In one embodiment, these personal data devices  104 - 108  couple to the central data device  102  over a data network, such as a global data network (e.g., the Internet). Similarly, a local data device  110  can couple to the central data device  102 . In one embodiment, the local data device  110  can store a complete or partial copy of the data stored in the central data device  102 . 
     The data exchange system  100  can also support a plurality of mobile devices (MD)  112 - 118  that can interact with a corresponding one of the personal data devices  104 - 108  or the local data device  110 . For example, the mobile device (MD-A)  112  can couple to the personal data device A  104  over a wired or wireless link  120 . The mobile device (MD-A)  112  can also wirelessly couple to any of a number of other electronic devices to share data therewith. For example, the mobile device (MD-A)  112  can couple to one or more of the mobile devices (MD)  114 - 118  and/or the local data device  110  over a wireless link  122 . 
     The data being shared by the data exchange system  100  can be media data, user data, news data, etc. The data can also be referred to as personal data, namely, data that is stored on a user&#39;s device. The central data device  102  can be a central server, the local data device  110  can be a local server, the personal data devices  104 - 108  can be personal computers, and the mobile devices  112 - 118  can be highly portable electronic devices. For example, the highly portable electronic devices can be handheld or smaller. In one implementation, the highly portable electronic devices can be palm-sized, such that they easily fit within the hand or palm of its user. In another implementation, the highly portable electronic devices can be wearable. 
       FIG. 2  is a schematic diagram of a data exchange environment  200  according to one embodiment of the invention. The data exchange environment  200  is, for example, suitable for implementation by the data exchange system  100  illustrated in  FIG. 1 . The data exchange environment  200  provides the ability for electronic devices to share data from one device to another. The sharing of data enables the data to be more readily available. 
     The data exchange environment  200  includes central data  202 . The central data  202  represents centralized data that can be used by a variety of different electronic devices. As an example, the central data can be provided by the central data device  102  illustrated in  FIG. 1 . The data exchange environment  200  also includes stationary personal data  204 . The stationary personal data  204  is personal data that is stored within an electronic device that is generally stationary. As an example, the stationary personal data  204  can be stored within the personal data device A  104  illustrated in  FIG. 1 . The stationary personal data  204  can be acquired from the central data  202  over a link  206 . Some or all of the stationary personal data  204  can be provided as mobile personal data  208 . The mobile personal data can be acquired from the stationary personal data  204  over a wired or wireless link  210  and stored within an electronic device that is generally mobile. As an example, the mobile personal data  208  can be stored within the mobile device A  112  illustrated in  FIG. 1 . Similarly, the data exchange environment  200  can include stationary personal data that is coupled to the central data  202  over a link  214  and mobile personal data  216  that is coupled to the stationary personal data  212  over a wired or wireless link  218 . Hence, the central data  202 , the stationary personal data  204  and the mobile personal data  208  can represent a hierarchy of digital data, where data can be shared throughout the hierarchy. Since the data being shared is often associated with a given user, the data can be conveniently available at multiple points in the hierarchy. 
     The data exchange environment  200  can also permit data sharing between the mobile personal data  208  and the mobile personal data  216  over a link  220 . Typically, the link  220  is a wireless link. The wireless link can be implemented by radio frequency transmissions, optical transmissions, etc. Since the mobile personal data  208  and the mobile personal data  216  are typically associated with different users, the sharing of such data can provide access to data beyond that available from the hierarchy associated with the user. 
     The data exchange environment  200  can also include local data  222 . The local data  222  represents data that is to be provided in a specific geographical location. The mobile personal data  208  can be linked to the local data  222  by a link  224 , and the mobile personal data  216  can be linked to the local data  222  over a link  226 . The links  224  and  226  are typically wireless links. 
     Additionally, the mobile personal data  208  can couple to the central data  202  directly over a link  228 , and the mobile personal data  216  can couple to the central data  202  directly over a link  230 . Typically, the links  228  and  230  are wireless links. 
     Hence, the mobile personal data  208  can be acquired from any one or more of the central data  202 , the stationary personal data  204 , the mobile personal data  216 , or the local data  222 . Likewise, the mobile personal data  216  can be acquired from any one or more of the central data  202 , the stationary personal data  212 , the mobile personal data  208 , or the local data  222 . 
     The data being shared can vary depending upon implementation. For example, the data being shared may pertain to video, music, games, photos, playlists, slideshows, etc. As another example, the data can be resource data, such as a map, which possible could be displayed by the data device. The data being shared can also be subscription content. The data can also pertain to a profile, such as a profile associated with a user. One class of data that can be shared is media data. The nature in which media items are shared can be unrestricted or restricted. Examples of restricted sharing of media items include a media item that has limited-use rights or which contains only a sample of the full content. 
     The data being shared can be transferred to a recipient device by file transfer or streaming. The data being transferred can be received by one or more data devices. Examples of data devices include a media player, PDA, a speaker unit, a wireless transmitter/receiver unit, etc. Users of data devices can also create and distribute content through data sharing. The streaming can be limited so as to restrict the number of data devices simultaneously receiving the data. On the other hand, if the users of the data devices are subscribers to the streaming content (i.e., have a subscription), then the streaming can be unlimited as to subscribers. 
     Data can be shared after being purchased. For example, a recipient could purchase data from a remote server. The remote server would then cause the purchased data to be delivered to the recipient&#39;s data device. The purchase can be performed in real-time or can be deferred until a later point in time. Thereafter, the purchased data can be shared from the recipient&#39;s data device to another data device. 
     The sharing or exchange of data can be automatic, manual or a combination of manual and automatic. For example, automatic sharing of data can occur when a data device comes within range of a wireless transmission of data. As another example, data can be automatically transferred in the context of a synchronize operation. The synchronize operation can be automatic or operated in accordance with a schedule. The synchronize operation can also be manually initiated. 
     The manner by which the data arrives at the data device can depend upon implementation. For example, the data can be directly transferred to the data device, or the data can be indirectly transferred to the data device. For example, the data transfer can be between one data device to another data device. Alternatively, one data device can cause another data device to transfer desired data to a recipient data device. 
     A data device can be used to control the data that is on the device or on an associated host device. For example, a user of a data device could either purchase, or mark for later purchase, media that they hear. In such case, the purchased data can be eventually received at the data device associated with the user (purchaser). Alternately, the user of the data device may request a shuffling of the data stored on the data device. The shuffling is, in effect, a remote shuffle of the data in that the data device can receive a new set of data (e.g., media items) following the shuffle operation. 
       FIG. 3  is a block diagram of a media exchange system  300  according to one embodiment of the invention. The media exchange system  300  permits the exchange of media data between various different electronic devices. Media data pertains to media such as music, video, photos, games, and the like.

The wireless data network  306  can include one or more wireless data networks, such as cellular networks, WiFi networks, WiMAX networks, Bluetooth networks, etc. The media exchange system  300  can also include a local media server  308  that can couple to one or both of the wired data network  302  and the wireless data network  306 . 
     The central media server  301  stores or has access to numerous media items. The local media server  308  also stores or has access to various media items. In addition, the media exchange system  300  supports a plurality of portable media devices  310 ,  316  and  320 . The portable media device  310  can communicate with the personal computer  304  over a wired link  312  or a wireless link  314 . As an example, the wired link  312  can correspond to a cable that, if available, can interconnect the portable media device  310  to the personal computer  304 . The wireless link  314  can be provided by a short range wireless capability, such as Bluetooth, infrared, etc. Typically, the portable media device  310  would be capable of communicating with the personal computer  304  using either the wired link  312  or the wireless link  314 . 
     The portable media device  316  can couple to the wireless data network  306  over a wireless link  318 . Similarly, the portable media device  320  can couple to the wireless data network  306  over a wireless link  322 . In this regard, the portable media devices  316  and  320  can access the central media server  301  and/or the local media server  308  via the wireless data network  306 . In addition, the portable media devices  310 ,  316 , and  320  may be able to wirelessly access each other, thereby exchange media data between portable media devices. 
     Optionally, the media exchange system  300  illustrated in  FIG. 3  can also support a wireless hub  324 . The wireless hub  324  can couple to the personal computer  304  over a wireless hub  326 . An electronic device  328  can then couple to the wireless hub over a link  330 . In one embodiment, the link  330  is a cable. The electronic device  328  can be any of a wide variety of devices. For example, the electronic device  328  can be a stereo system, a printer, a television, a memory device, an appliance, a computer, etc. Alternatively, the wireless hub  324  could wirelessly couple to other devices within the media exchange system  300  besides the personal computer  304 . For example, the wireless hub  324  could wirelessly link to the central media server  301 , the local media server  308  or any of the media devices  310 ,  316  and  320 . 
     In one embodiment, one or more of the mobile devices, such as the mobile devices  310 ,  316  or  320  illustrated in  FIG. 3 , can pertain to media devices. More particularly, the media devices can pertain to media players, such as the iPod® media player from Apple Inc. These mobile devices can include a media management application that operates on the mobile device. One example of a media management application is iTunes®, available from Apple Inc. Given the portability of mobile devices, mobile devices are smaller and have less resources. Consequently, a media management application designed for use on a mobile device may offer less features and capabilities than would a counterpart media management application operating on a larger, more powerful computing device, e.g., a personal computer. Given that the mobile devices have wireless access to the local media server  308  or the central media server  301 , the mobile devices can interact with the media servers  301  and  308  to request and/or receive media data (or other data). In this regard, a media management application operating on the mobile devices can communicate with the media servers  301  and  308  to perform various tasks, including: navigating available media content at the servers (such as navigation of a media store), receiving a periodic delivery of media content to media devices (such as daily pushing media data from a server to a media device), etc. 
     Peer-to-Peer Data Sharing 
     According to another aspect of the invention, mobile devices (e.g., portable media devices) can communicate with one another. This type of communication can be referred to as peer-to-peer interaction. In this regard, one mobile device can communicate (e.g., unicast) directly with another mobile device. In another example, one mobile device can communicate (e.g., broadcast, anycast or multicast) to a plurality of other mobile devices. Still further, a mobile device can interact with other electronic devices besides a mobile device, such as portable media devices. For example, other electronic devices include speakers, computers, accessories, home entertainment products, etc. 
     A mobile device, such as a portable media player, can also operate as a remote controller for other electronic devices. For additional details on a portable media player operating as a remote controller, see, e.g., U.S. patent application Ser. No. 11/314,291, filed Dec. 20, 2005, entitled “PORTABLE MEDIA PLAYER AS A LOW POWER REMOTE CONTROL AND METHOD THEREOF”, now U.S. Pat. No. 7,702,279, which is hereby incorporated herein by reference. 
     In the peer-to-peer environment, one mobile device can communicate with one or more other electronic devices (whether mobile or stationary) in the immediate vicinity. Data sharing can be performed when such communication is available. 
     In a public environment, such as a train, mobile devices can serve to enable riders on the train to share data in a peer-to-peer manner. In this regard, the mobile devices would discover other nearby (e.g., in the vicinity) mobile devices and then proceed to transfer data. The nature and extent of the data transfer can be controlled. For example, the data to be shared can be restricted (partially or fully) and/or require authorization. The type of data being exchanged can be media data or other data (e.g., contact information, user profile, etc.). 
     In the home environment, the peer-to-peer data transfer could be between a mobile device and a computing device, such as a home computer or another mobile device. Typically, the mobile device and the computing device would be associated with a particular user. For example, when the mobile device is within range of a home computer (or a home network), data transfer can be performed between the mobile device and the home computer. The data transfer can be automatic without any user action or can alternatively require manual approval by a user. In one embodiment, the data transfer can be part of a synchronization operation. For additional details on synchronization, particularly in a wireless manner, see, e.g., U.S. application Ser. No. 10/987,649, filed Nov. 12, 2004, and entitled “WIRELESS SYNCHRONIZATION BETWEEN MEDIA PLAYER AND HOST DEVICE”, now U.S. Patent Publication No. 2006/0168351, which is hereby incorporated herein by reference. 
     In the work environment, as a user comes into an employer&#39;s office to work, the user&#39;s mobile device can transfer data to the user&#39;s work computer or to a network server for the office. The data transfer can be automatic without any user action or can alternatively require manual approval by a user. The user of the mobile device can also communicate with mobile devices of coworkers to exchange data. For example, in a meeting in a conference room, a mobile device having a slide presentation can be shared (e.g., streamed or transferred) to each of the mobile devices within the conference room. 
     Regardless of the particular environment, the data transfer can be wireless. The wireless data transfer can be facilitated by a wireless network. One mobile device could wirelessly transmit data in a unicast fashion from one mobile device to another mobile device or stationary computing device. Still further, one mobile device could wirelessly transmit data in a multicast or broadcast fashion to a plurality of other mobile devices. 
     The data being transferred can be associated with various types of data. For example, the data can pertain to personal information (such as a user profile), work documents, media data, etc. In one embodiment, the sharing of such data can be managed on mobile devices to control the type and extent of data transfer that is performed. Such control can be associated with the mobile device that is sending the data as well as a mobile device that is receiving the data. 
     In another embodiment, one mobile device can transmit their preferences within the general vicinity. The preferences that have been essentially published can then be used by other mobile or stationary devices within the proximity to determine whether they have any data for sharing with the mobile device, where such data for sharing is determined in accordance with the preferences that were transmitted. Also, in the context of personal information sharing, a user of a mobile device can provide a personal user profile that can be exchanged with other nearby mobile devices or stationary devices so that users of such other devices can understand the user of the mobile device and what his/her interests might be. 
     As noted previously, media devices are able to wirelessly share data with one another. For example, a user of a media device may configure or arrange for a subset of its media data to be shareable with other media devices. The scope or extent of sharing being permitted can be controlled by the media device, such as through use of a graphical user interface available on the media device. Alternatively, the scope or extent of sharing being permitted can be controlled by another media device. Additionally, in one embodiment, to facilitate sharing of media data, if a first user of a media device shares with a second user of another media device, the first person can receive an incentive reward for such sharing. In one example, the incentive award can be on-line media store credits. The nature or degree of the credits can be increased or restricted to those situations in which the second user buys the media content being shared from an authorized source, such as an on-line media store. In one embodiment, the media content being shared from the first media device to the second media device is a playlist. 
       FIG. 4  is a block diagram of a peer-to-peer media sharing arrangement  400  according to one embodiment of the invention. The media sharing arrangement  400  inclues a mobile media device  402  that wirelessly couples to one or more other mobile media devices  404 - 408 . The mobile media device  402  can transmit media content to one of the mobile media devices  404 - 408 , a plurality of the mobile media devices  404 - 408 , or all of the mobile media devices  404 - 408 . The transmission of the media content can, for example, be by broadcast, anycast, unicast, or multicast. 
       FIGS. 5A-5C  illustrate wireless media sharing in a peer-to-peer environment according to one embodiment of the invention. In  FIG. 5A , a wireless media sharing system  500  is depicted having a mobile media device  502  providing a wireless network  504 . Although the wireless network  504  is omni-directional, it should be understood that the wireless network  504  could also be substantially directional. As shown in  FIG. 5A , a mobile media device  506  is outside of the wireless local network  504  provided by the mobile media device  502 . Accordingly, in the configuration shown in  FIG. 5A , the mobile media device  502  and the mobile media device  506  are not able to communicate over the wireless network  504 . In other words, the mobile media device  506  is out of range of the wireless network  504  provided by the mobile media device  502 . Hence, even if the mobile media device  502  were transmitting data, the mobile media device  506  would be out of range and thus unable to receive the transmitted data. 
     In  FIG. 5B , the mobile media device  506  has been repositioned, such as through movement of the user of the mobile media device  506 . As a result, the mobile media device  506  is now within the wireless network  504 . In other words, as shown in  FIG. 5B , the mobile media device  506  is within range of the wireless network  504  provided by the mobile media device  502 . Consequently, data can be transferred from the mobile media device  502  to the mobile media device  506 . The mobile media device  506  would also typically be able to transfer data from the mobile media device  506  to the mobile media device  502 . 
     In  FIG. 5C , the wireless media sharing system  500  is generally similar to that illustrated in  FIG. 5B , except that another mobile media device  508  is also provided within the wireless network  504 . In this case, the mobile media device  502  can communicate with both the mobile media device  506  and the mobile media device  508 . In one example, the mobile media device  502  can multicast or broadcast to both of the mobile media devices  506  and  508 . 
     The media sharing that can be performed by the wireless media sharing system  500  illustrated in  FIGS. 5A-5C  can be used in a variety of different environments. For example, if the wireless network  504  is at home, the providing of a mobile media device in the home allows media transfer to occur with respect to the mobile media device. Similarly, when the wireless network  504  is at one&#39;s place of work, then the providing of the mobile media device at the place of work facilitates data transfer with the mobile media device. As another example, in public locations, mobile media devices may be within wireless range of one another, such that media transfers can occur, even if the users of the mobile media devices are unknown to one another. 
     Besides sharing media data between mobile media devices, other types of data can be shared. For example, personal information can be transferred between mobile media devices. The personal information to be shared can be transmitted (e.g., broadcast) by one mobile media device to other mobile media devices, provided the devices are within wireless range. In another example, a mobile media device can transfer personal information to other mobile media devices within wireless range that satisfy predetermined criteria (e.g., rules). For example, mobile media devices can make available personal information, such as characteristics of their users, interests, contact information, etc., and the mobile media devices can examine the predetermined criteria to determine whether information should be transmitted or exchanged with such mobile media devices. 
     As noted above, a primary mobile device can operate to discover other mobile devices that are nearby through use of a wireless network. Typically, the wireless network is a local wireless network that supports only short-range communications. One example of the short-range can be less than 100 meters. Another example of short-range can be less than 25 meters. Still another example of the short-range can be less than 10 meters. Hence, the availability of another mobile device on the local wireless network signals that such mobile device is within the vicinity of the primary mobile device. In another embodiment, a remote network and a remote server computer can be used to determine when mobile devices are nearby. The locations of the mobile devices can be examined to determine if the devices are nearby. The mobile devices can use global positioning systems (GPS) or network triangulation to determine their positions. The remote network and the remote server can also be used to transfer data between the mobile devices that are nearby. As ex example, the remote network can include a mobile (e.g., cellular) telephone network. 
     Local Data Sharing 
     Another aspect of the invention pertains to a local content server. The local content server operates within a local wireless environment. The local content server can be provided at a particular location, such as a business (i.e., establishment), city or other entity for the purpose of wirelessly transmitting data to a nearby mobile device. In other words, when a mobile device is within the vicinity of the local content server that is provided at the particular location, the mobile device is able to transmit/receive data with the local content server. As used herein, “in the vicinity” means a region at or near a location. 
     In the case of a business, such as a coffee shop, theater or retail store, the business may provide an in-store content server that provides a data access point in a wireless manner. In one example, the business could be normally broadcasting media data (e.g., music or other audio information) to patrons within their business. The media data can be provided locally by a media system (e.g., sound system), which may be part of the local content server. In addition, the local content server can enable additional data to be wirelessly transmitted to the mobile devices of patrons within the business. 
     As an example, if a sound system were playing music within the business&#39; premises, a patron&#39;s mobile device provided within the business&#39; premises could receive information about the song being played by way of a wireless transmission from the local content server to the patron&#39;s mobile device. Such information regarding the song being played could then be presented on a display screen of the patron&#39;s mobile device for the patron to view. In addition, the display screen on the patron&#39;s mobile device can enable the patron to access further information regarding the business or the media being played. This additional information can facilitate the purchase of media or other products or services available from the business. For ease of purchase, a one-click or few clicks option to purchase the media or other products can be made available. Still further, a user could indicate or mark/tag a media item or other product for future consideration for purchase. 
     As another example, a user of a mobile device may be at a movie theater and may hear or otherwise desire to access a movie soundtrack or video trailer. Given the user&#39;s location at the movie theater, the mobile device of the user can receive a wireless transmission (via a local content server) of a soundtrack or video trailer if so desired by the user. Further, a more specific user location at the movie theater (e.g., at a region associated with a first movie) can be used to determine the data to be transmitted to the mobile device of the user. The user may also receive advertisements that are targeted to persons who are generally interested in movies or specifically interested in the movie associated with the soundtrack or video trailer. The advertisements can be presented on the display screen on the mobile device. The user can also purchase tickets for the user at the movie theater using the mobile device. 
     As yet another example, a city may want to make certain city data readily available to persons within the city. For example, the city may provide a city map with locations of interest to persons within the city by way of a wireless local server. In such a case, a mobile device within city limits would be able to wirelessly receive an electronic version of the city map. A smaller scale implementation can also be provided for a town, community or village. 
     Regardless of the particular type of entity that the user of a mobile device visits, the location of the user can infer user interest or preferences. For example, when the user is at a movie theater, the user is likely interested in movies. As another example, when the user is at an airport, the user is likely interested in flight arrival and departure times. 
     The fact that certain patrons in a business&#39; store have mobile devices can also facilitate the business in gathering information on patrons. For example, by interaction with mobile devices of patrons that are in the vicinity of the business&#39; site, the business can receive a profile associated with the patron. In one embodiment, the profile can indicate characteristics of the person, age, salary range, and interest. Other information businesses might receive from the mobile device could be the time the patron was in the store, how frequently the patron visits stores of the business, etc. 
     In general, content received at a predetermined location can be customized or personalized for the user of the mobile device. For example, the customization or personalization can be based on user preferences, user characteristics, listening habits and/or the environment. For example, if your user preferences or listening habits indicate that you like country music, then, when visiting a business, the business can provide information to your mobile device that is customized or personalized for users that like country music. For example, if the user enters a music store to browse music, the user&#39;s mobile device can be presented with information concerning country songs or associated products that may be of interest to the user. 
       FIG. 6A  is a block diagram of a wireless media sharing system  600  according to one embodiment of the invention. The wireless media sharing system  600  includes a local media server  602 . The local media server  602  is, for example, suitable for use as the local media server  308  illustrated in  FIG. 3 . The local media server  602  stores or has access to various media items. A wireless transceiver  604  couples to the local media server  602  and produces a wireless network  606 . Wireless communications between the wireless transceiver  604  and mobile devices (wireless devices)  608  and  610  allow the mobile devices  608  and  610  to interact with the local media server  602 . More particularly, the wireless transceiver  604  can provide the wireless network  606 , and the mobile devices  608  and  610  can interact with the local media server  602  so long as the mobile devices  608  and  610  are within the wireless network  606 . Additionally, the local media server  602  can be coupled to a central media server, such as the central media server  301  illustrated in  FIG. 3 , via a network link  612 . 
     The wireless media sharing system  600  can be provided at a particular venue and offer wireless interaction for users of mobile devices while at the venue. The venue can also participate in co-branding of the media being provided to the mobile devices  608  and  610  at the venue. For example, the venue could be a coffee shop, theater or a retail store. The local media server  602  can provide access to a central media server. The local media server  602  can transfer (e.g., broadcast, anycast or multicast) media to the mobile devices  608  and  610 . The local media server  602  can also dynamically determine which media items are to be transmitted (e.g., broadcast) or played at the venue based on the characteristics of the users of the mobile devices  608  and  610  at the venue. Still further, the local media server  602  could also acquire information from users of the mobile devices  608  and  610 . For example, the acquired information can pertain to user characteristics, user rating of media items, how long users have been in the store, what portions of the store they found most interesting, and what media items they were receiving (e.g., listening to). 
     The venue can also facilitate the users of the mobile devices  608  and  610  in buying media content, either from the local media server  602  or a central media server. The local media server  602  can also provide information on what songs or other media is currently playing at the venue, and the mobile devices  608  and  610  can store and/or display such information on a display screen. A user of the mobile devices  608  and  610  can also select, mark or tag a media item they hear or see while in the venue, so that the media item can be automatically purchased, added to an interest list, or available for deferred purchase. 
     As previously noted, the venue can also gather information concerning the users of the mobile devices  608  and  610 . Such information can include when and how often the users were in the venue. Further, different users, based on their preference or criteria settings, can receive different or personalized media content while at the venue. In another embodiment, users could make requests for particular media content, such as through making selection with reference to a user interface for the mobile devices  608  and  610 . 
     The location of the venue and/or the media devices can infer the interest or preferences of the users. For example, if the venue is an airport, a local media server could provide airport arrival and departure information, weather, etc. that a traveler might desire. As another example, if the user is visiting a city (e.g., one that they have not lived in for some time), the local city map may be of interest and available from a local server. As still another example, a venue, such as a movie theater, can provide a local media server that would facilitate the buying of movie tickets or soundtracks and could also make video trailers available. 
     The local media server  602  together with the wireless transceiver  604  can broadcast or multicast media content to mobile devices  608  and  610 . The mobile devices  608  and  610  can also restrict or limit what type of data they permit to be received. For example, the user of the mobile device  608  can enter user preferences that operate to automatically filter out unwanted transmissions from local servers. On the other hand, the local media server  602  can examine the user preferences, criteria or listening habits of a user and then transmit user data that is consistent with their interests. 
       FIG. 6B  is a block diagram of a distributed wireless data sharing system  620  according to one embodiment of the invention. The distributed wireless data sharing system  620  can include a plurality of local media systems (LMS) that are provided at different locations, such as at different venues or establishments. In particular, as illustrated in  FIG. 6B , the distributed wireless data sharing system  620  includes a first local media system (LMS-1)  621  that provides a wireless environment  622  at a first location; a second local media system (LMS-2)  624  that provides a wireless environment  626  at a second location; a third local media system (LMS-3)  628  that provides a wireless environment  630  at a third location; and a fourth local media system (LMS-4)  632  that provides a wireless environment  634  at a fourth location. Each of the plurality of local media systems  621 ,  624 ,  628  and  632  can couple to a data network  636 . As an example, the data network can be a local area network, a wide area network or global data network, such as the Internet. 
     A central media system (CMS)  638  can also be coupled to the data network  636 . The central media system  628  can provide centralized storage, sales, management and/or distribution of electronic data, such as media content. Media content can pertain to one or more different types of media, including music, video, audiobooks, podcast, and images. More particularly, any of the local media systems  621 ,  624 ,  628  and  632  can interact with the central media system  638  to acquire media content. Then, the local media system  621 ,  624 ,  628  and  632  can broadcast, multicast or otherwise deliver media content to mobile electronic devices that are within range of their wireless environments  622 ,  626 ,  630  and  634 , respectively. In addition, information, such as patron information (e.g., demographics, profile or feedback), acquired at the local media systems  621 ,  624 ,  628  and  632  can be provided to the central media system  638 . The central media system  638  can use the patron information to better provide data or other services for patrons at the various locations supported by the local media systems  621 ,  624 ,  628  and  632 . 
     According to another aspect of the invention, a customized media environment can be provided at an establishment. In one embodiment, the customization is automatic or dynamic so that user or patron interaction may not be needed. In another embodiment, patron interaction can be used to provide the customized media environment. 
     The customized media environment can be associated with a media store. The media store can be provided at a remote server that is operatively connected to the customized media environment by way of a network. Alternatively, the media store can be provided by the customized media environment itself by way of a local server. 
     The customized media content can depend upon the patrons within the store, currently or recently or over time (e.g., historically). In this regard, the customized media content for the customized media environment can be different at different establishments, even the same type of establishment in different locations may have different customized media environments. The customization can also be dependent upon the demographics of the customers, time of day, etc. The customization of the media environment can be determined based on what is popular in the associated geographic area. For example, the top 40 media items being purchased (e.g., from an online media store) by persons in the region (e.g., city) of the establishment can be selected as the customized media content for the establishment. 
     Besides customizing a media environment for a particular establishment, different users or classes of users can be presented with different user interfaces. For example, a child might be presented with a reduced feature interface, whereas a college student may receive a sophisticated user interface with full-featured support. 
     Although the wireless data sharing systems discussed above in  FIGS. 6A and 6B  provide a local server or system (e.g., local media server) at an establishment or location, it should be understood that in other embodiments, a server or part of the system could be provided remotely from the establishment or location, yet connected through wired and/or wireless networks. Such remotely provided server or part of the system could also even be used to support data sharing at multiple establishments or locations. 
       FIG. 7  is a flow diagram of a dynamic media selection process  700  according to one embodiment of the invention. The dynamic media selection process  700  is, for example, performed by a local media server (e.g., the local media server  602  illustrated in  FIG. 6A ) or local media system (e.g., any of the local media systems  621 ,  624 ,  628  and  632  illustrated in  FIG. 6B ). 
     The dynamic media selection process  700  initially provides a local media content broadcast at an establishment. In one embodiment, the local media content can be broadcast by streaming the local media content from a local media server over a localized wireless network provided at the establishment. In another embodiment, the local media content can be broadcast over radio waves, such as localized AM or FM broadcasts. Users or patrons of the establishment that have a wireless electronic device are able to receive the broadcasted local media content via a wireless network or localized AM or FM broadcast. In still another embodiment, the local media content can be broadcast by a media system (e.g., sound system) having media output devices (e.g., speakers) at the establishment. 
     Once the local media content broadcast is provided  702 , a decision  704  can determine whether local media content being broadcasted is to be updated. In other words, the decision  704  determines whether the local media content being broadcast at the establishment should be updated at this time. In one implementation, the media content can be periodically evaluated for an update, such as every ten (10) minutes or some other predetermined period of time. In any case, when the decision  704  determines that media content update should be performed, characteristics, preferences and/or requests of one or more patrons at the establishment are obtained  706 . The characteristics, preferences and/or requests are from those patrons at the establishment that have mobile devices (i.e., wireless electronic devices). 
     After the characteristics, preferences and/or requests of the patrons are obtained  706 , updated media content can be determined  708  based on the obtained characteristics, preferences and/or requests. The determination  708  of the updated media content can thus be influenced by the patrons at the establishment. The mobile devices associated with such patrons can interact with a local media server at the establishment to exchange the characteristics, preferences and/or requests. The local media server can then accumulate the characteristics, preferences and/or requests and determine whether an update to the existing media content should be performed. As an example, the media content can be updated to different media content that is more to the liking of the patrons at the establishment. In one embodiment, characteristics, preferences and/or prior requests of patrons can be used to dynamically influence media selection at the establishment without any patron participation. In another embodiment, requests of patrons can be used to influence media selection at the establishment through such patron participation. 
     After the updated media content has been determined  708 , the local media content broadcast at the establishment can be updated  710 . The update to the local media content broadcast could be implemented immediately or in a deferred manner. To defer the local media content broadcast update, a media output queue could be utilized to hold the sequence of media content to be broadcast. In any case, following the block  710 , the dynamic media selection process  700  returns to repeat the decision  704  and subsequent blocks so that the media content being broadcast can be repeatedly updated. 
       FIG. 8  is a flow diagram of a patron discovery process  800  according to one embodiment of the invention. The patron discovery process  800  can, for example, be utilized by the block  706  of the dynamic media selection process  700  illustrated in  FIG. 7  to determine those patrons having mobile devices that are at an establishment. 
     The patron discovery process  800  can begin with a decision  802 . The decision  802  determines whether an establishment should be queried for patrons. Typically, the establishment would be queried for its current patrons on a periodic basis. When the decision  802  determines that it is not time to query for patrons, the patron discovery process  800  waits for the appropriate time. On the other hand, when the decision  802  determines that it is an appropriate time to query the establishment for patrons, mobile devices of patrons at the establishment are discovered  804 . Typically, mobile devices that support wireless interaction can be discovered  804  if they are in range of a wireless access point provided at the establishment. In one embodiment, the range of the wireless access point includes at least a substantial part of the establishment. In another embodiment, the range of the wireless access point further includes the vicinity of the establishment. Here, well known network discovery techniques can be used to locate the mobile devices (with wireless capabilities) that are located at the establishment. The mobile devices can vary. As an example, the mobile devices can include portable media players, mobile phones, personal digital assistants (PDAs), portable game players, etc. 
     Once the mobile devices are discovered  804 , information can be acquired from the mobile devices that can be utilized by a local media server at the establishment. In particular, a first discovered mobile device can be initially selected  806 . A decision  806  can then determine whether information sharing has been authorized by the patron associated with the mobile device. In this embodiment, a patron (user) of a mobile device is given the option of participating or declining participation in information sharing. 
     When the decision  808  determines that information sharing has been authorized, then patron data can be retrieved  810  from the mobile device. The patron data can refer to characteristics, preferences and/or requests of a patron that are stored in the mobile device associated with the patron. On the other hand, when the decision  808  determines that information sharing has not been authorized, then the block  810  is bypassed because the patron has not authorized sharing of its patron data. 
     In any case, following the block  810  or following the decision  808  when the block  810  is being bypassed, a decision  812  determines whether more discovered mobile devices are to be processed. When the decision  812  determines that there are more mobile devices to be processed, the patron discovery process  800  returns to repeat the block  806  so that a next discovered mobile device can be selected and similarly processed. Alternatively, when the decision  812  determines that no more discovered mobile devices are to be processed, the patron discovery process  800  returns to repeat the block  802  so that the patron discovery process  800  can repeat its processing, typically on a periodic basis. 
     Another aspect of the invention is an establishment that provides a plurality of broadcasts. The broadcasts are local to the establishment. When a user of a mobile device enters an establishment, the user can receive a plurality of broadcasts that are made available by the establishment. Typically, the establishment would utilize a media delivery server at the establishment to provide the one or more broadcasts over a wireless data network. As an example, the mobile device of the user can present a graphical user interface that identifies the available broadcasts at the establishment and allows the user to select the desired broadcast. As another example, the mobile device of the user could alternatively automatically select from the available broadcast based on preferences, user history or the like. These broadcasts can also be implemented as multicasts. 
       FIG. 9  is a flow diagram of a broadcast selection process  900  according to one embodiment of the invention. The broadcast selection process  900  can operate to permit a patron at an establishment to select one of a plurality of available broadcasts made available at the establishment. The broadcast selection process  900  is, for example, performed by a local media server (e.g., the local media server  602  illustrated in  FIG. 6A ) or local media system (e.g., any of the local media systems  621 ,  624 ,  628  and  632  illustrated in  FIG. 6B ). 
     The broadcast selection process  900  begins with a decision  902  that determines whether a patron has been discovered. Here, when the patron has an electronic device (mobile device), a local server at the establishment can discover the presence of the electronic device at the establishment. Hence, once the decision  902  determines that a patron has been discovered, the mobile device associated with the patron can be informed  904  of the available broadcasts at the establishment. In another embodiment, an establishment may offer a plurality of concurrent broadcasts of different data. Here, in one embodiment, the local server can wirelessly transmit a list of the available broadcasts. In one example, the list can be provided as a markup language document (e.g., XML document) containing descriptive data (e.g., metadata) pertaining to the available broadcasts. The mobile device can interpret the markup language document to present local broadcast information on a display of the mobile device.  FIG. 10 , which is described below, provides an example of a presentation of local broadcast information on a display. 
     After the mobile device associated with the patron has been informed  904  of the available broadcast, a decision  906  can determine whether a broadcast selection has been made. Here, the patron may select one of the available broadcasts to receive while at the establishment. For example, the broadcast selection can be made with respect to local broadcast information being presented on the display of the mobile device. As a particular example, a user can interact with a user interface associated with the mobile device to select one of the available local broadcasts. Such selection can utilize a button, dial, touch surface, voice or other user input means of the mobile device. When the decision  906  determines that a broadcast selection has not been made, then it is assumed that the patron has declined to receive any of the available broadcasts. In this case, the broadcast selection process  900  returns to repeat the decision  902  and subsequent blocks so that the broadcast selection process  900  can be repeated for each discovered patron. 
     On the other hand, when the patron does select one of the available local broadcasts, the selected broadcast can be transmitted  908  to the mobile device associated with the patron. Typically, a local media server provided at the establishment would configure its wireless transmission such that the selected broadcast is wirelessly transmitted via a wireless network to the mobile device associated with the patron while in the vicinity of the establishment. In this manner, the mobile device is able to receive the selected broadcast and present the media content or other data associated therewith to the patron, who is the user of the mobile device. Following the block  908 , the broadcast selection process  900  returns to repeat the decision  902  and subsequent blocks so that the broadcast selection process  900  can be repeated for each discovered patron. To the extent that multiple mobile devices are to receive the same broadcast, the transmission of the selected broadcast can be implemented by broadcasting or multicasting for efficient data transmission. 
       FIG. 10  illustrates an exemplary local broadcast screen  1000  according to one embodiment of the invention. The local broadcast screen can represent a screen being displayed on a display of a mobile device associated with a patron. The local broadcast screen  1000  can thus inform the patron of the local broadcasts that are available. In this example, the patron is informed that the establishment is presently offering four different local broadcasts, namely, “Week 3—NFL”, “Financial News”, “Classical Mix”, and “Pop Mix”. In addition, the local broadcast screen  1000  indicates a “Decline” selection as also being available in the event that the patron desires to decline to receive any of the local broadcasts. The patron can interact with the local broadcast screen  1000  to either select one of the available local broadcasts or to decline the broadcasts. 
       FIGS. 11A and 11B  are flow diagrams of a media channel selection process  1100  according to one embodiment of the invention. The media channel selection process  1100  is, for example, performed by a mobile device (i.e., wireless electronic device), such as the mobile device  608  or the mobile device  610  illustrated in  FIG. 6A . 
     The media channel selection process  1100  initially participates  1102  in detection of a mobile device (associated with a patron) at an establishment (or venue). Typically, the mobile device would be detected by a local server shortly after the patron enters the establishment. Next, available media content information is obtained  1104  from the local server. Typically, the available media content information would be obtained  1104  by wireless interaction of the mobile device with the local server. Then, a decision  1106  determines whether a preference setting associated with the patron or the mobile device influences the media channel selection. When the decision  1106  determines that a preference setting does influence the media channel selection, the media channel is selected  1108  based on the preference setting. 
     On the other hand, when the decision  1106  determines that there is no preference setting that affects the media channel selection, a graphical user interface is presented  1110  on a display of the mobile device. As an example, the graphical user interface being presented  1110  is a display screen that presents to the user indications (e.g., titles, abstracts, summaries, or images) of one or more media channels that are available at the establishment for selection. Next, a decision  1112  determines whether a user selection has been made. Here, the user selection can correspond to selection of one of the available media channels as indicated on the graphical user interface. Once the decision  1112  determines that a user selection has been made, a media channel can be selected  1114  based on the user selection. 
     Following the block  1108  or the block  1114 , the mobile device can request  1116  to receive the selected media channel. Here, the request  1116  to receive the selected media channel is provided to the local server. In response to the request  1116 , the mobile device can receive and present  1118  media content over the selected media channel. The media content being received over the selected media channel can be provided to the mobile device in a wireless manner, such as through streaming. As an example, the media content being received can be audio or video data being streamed to the mobile device over a wireless data network. Following the block  1118 , the media channel selection process  1100  ends. However, it should be recognized that the media channel selection process  1100  can be repeated each time a patron is discovered at the establishment. 
     Although the media channel selection process  1100  primarily concerns delivering media content associated with a selected media channel to a mobile device, other electronic data can be exchanged between the local server and the mobile device. As examples, the mobile device can optionally also interact with the local server to provide feedback to the local server, obtain information on other topics of interest from the local server, receive product or service information associated with products or services offered by the establishment, etc. For example, current sales or coupons at the establishment can be made available to the mobile device by the local server. Such other electronic data can thus facilitate ecommerce transactions for products or services offered at the establishment. 
     According to another aspect of the invention, an establishment provides local replay of specific data. The specific data can provide a replay of a previously recorded media item, such as an audio or video recording. For example, the replay can pertain to a recent sporting event or current news, which can be in audio or video formats. The patron to the establishment can receive the local replay via wireless means to their mobile device. In one embodiment, the specific data for the replay can be provided by a local transmission or a media channel as discussed above. In an alternative embodiment, the patron can physically connect their mobile device to a port provided at the establishments to receive the specific data by a wired means. 
     According to another aspect of the invention, an establishment (such as a store) can allow users with mobile devices to either influence digital content being locally transmitted at the vicinity of the establishment or permit users to request certain digital content be locally transmitted or otherwise made available. The digital content can be media content. In one embodiment, the digital content can be transmitted by streaming data from a local server over a localized wireless network provided at the establishment to one or more mobile devices of patrons. In another embodiment, the digital content can be broadcast over radio waves, such as localized AM or FM broadcasts, to mobile devices of patrons that are within the vicinity of the establishment. In still another embodiment, the digital content can be broadcast by a media system (e.g., sound system) having media output devices (e.g., speakers) at the establishment. 
     In one embodiment, the establishment can provide a data delivery server (e.g., local server) which can operate as a jukebox. A patron to the establishment can influence the data being presented (i.e., served) by the data delivery server. In one embodiment, the media content can be influenced by the mobile devices of patrons within the establishment. For example, if a substantial percentage of the media devices associated with patrons that are fond of country music, the media content being transmitted (e.g., broadcast) by the data delivery server can provide country related media (e.g., country music). In one implementation, a patron within the establishment can influence the media content through one or more preferences that have been previously saved on their mobile device. In another implementation, a patron within the establishment can influence the media content by interaction with the data delivery server. As an example, the patron can be presented with a menu on their mobile device. Through interaction with the menu, the patron can signal the data delivery server of the particular digital content that the patron would prefer to receive (e.g., hear) while in the establishment. 
     In the case in which there are multiple patrons attempting to influence the digital content being delivered at the establishment, the data delivery server can operate to determine the particular digital content to be delivered. For example, the data delivery server could determine that it will automatically determine the data to be delivered based upon the preferences or interests of the patrons with mobile devices within the establishment. Here, the system can automatically adjust the digital content being delivered based upon the preferences or interests of its patrons. As another example, when a user is providing explicit data delivery request, such as through menu interaction as noted above, the data delivery server can operate to place a particular data item (e.g., media item) in a delivery queue. The particular data item can be specifically selected by the patron or can be pseudo randomly selected by the data delivery server based on more general criteria provided by the patron. The data delivery server can output the data item in accordance with the delivery queue. The influence on the data delivery can be used in selecting the particular media items or classes of media items. The user influence or specific requests can be based on types of music, news, sports, etc. For example, if a substantial portion of the patrons want to listen to sports, as opposed to music, the data delivery server could transition to provide sports related content. 
     Another aspect of the invention is a subscription service for data, such as music or sports data. As an example, the subscription service can be associated with a user that has a mobile device. As the user and the mobile device enter an establishment, the establishment can recognize the user as a member of the subscription service and then permit (on-demand or automatically) delivery of data to the mobile device. Normally, the data delivery would be wireless. The data being delivered can be periodically made available, such as daily or weekly. For example, a user can visit a particular establishment on a weekly basis and when they visit the establishment they can receive the weekly data (data for the week). As a more specific example, if the establishment pertains to a chain of coffee shops, when the user (that is a subscriber) visits any of the coffee shops, they can receive the weekly data. For example, the weekly data can pertain to a song of the week, sports highlights for the week, financial news for the week, etc. The weekly data can be in the form of a media item. This type of system allows for the convenient distribution of data to mobile users, while at the same time encouraging such mobile users to visit certain establishments. 
     In another embodiment, a user (patron) may have acquired (e.g., purchased) a subscription service to receive certain digital data. The digital content associated with the subscription can be obtained when the user (patron) visits an establishment that supports the subscription service. 
       FIG. 12  is a flow diagram of a subscription data delivery process  1200  according to one embodiment of the invention. The subscription data delivery process  1200  allows a user of a mobile device to subscribe to an electronic subscription service to receive data in a periodic manner. As an example, the subscription service can pertain to a weekly or daily media service that respectively provides daily or weekly media content of interest to the user. As discussed below, the establishment can provide a local server to facilitate the delivery of the subscription data to mobile devices associated with users (patrons). The user of the mobile device becomes a patron at an establishment when the user enters the vicinity of the establishment. According to the subscription, the media content is made available in accordance with the periodic nature of the subscription. Consequently, the user is motivated to visit a participating establishment periodically so as to receive the subscription data. 
     The subscription data delivery process  1200  begins with a decision  1202  that determines whether a patron has been discovered at the establishment. Typically, a patron can be discovered at the establishment by discovering a mobile device associated with the patron in the vicinity of the establishment using a wireless network provided by the establishment. When the decision  1202  determines that a patron has not been discovered, the subscription data delivery process  1200  awaits the discovery of a patron. Once the decision  1202  determines that a patron has been discovered, an identifier from the mobile device associated with the patron can be retrieved  1204 . Then, a decision  1206  can determine whether the patron has an electronic subscription service. Here, the decision  1206  can be performed by a server, such as the local server or a remote server, to determine whether the patron, as identified by the identifier, has an electronic subscription service that is supported by the local server at the establishment. When the decision  1206  determines that the patron does have an electronic subscription service that is supported by the local server at the establishment, a decision  1208  determines whether there is any subscriber data to be delivered to the patron at this time. When the decision  1208  determines that there is subscriber data to be delivered, the patron can be prompted  1210  to approve delivery of the subscriber data. For example, the patron may choose not to receive the subscriber data during this visit to the establishment. Alternatively, the patron could configure their mobile device to automatically approve the delivery of such data. In any case, when the decision  1212  determines that delivery is approved, the subscriber data, namely, current subscriber data, is delivered  1214  to the mobile device of the patron. Typically, the local server would download or stream the subscriber data to the mobile device. On the other hand, no subscriber data is delivered to the mobile device of the patron if the decision  1212  determines that delivery is not approved as well as when there is no subscriber data to be delivered. Hence, following the block  1214 , as well as following the decisions  1206 ,  1208  and  1212  when the tested condition is not present, the subscription data delivery process  1200  ends for the particular patron that has been discovered. Although the subscription data delivery process  1200  ends, the subscription data delivery process  1200  can repeat its processing each time a patron is discovered. 
       FIG. 13A  is an exemplary subscription data availability screen  1300  according to one embodiment of the invention. The subscription data availability screen  1300  can represent a screen being displayed on a display of a mobile device associated with a patron. The subscription data availability screen  1300  can be presented to a patron to approve or decline delivery of subscription data (e.g., new Sports Highlights Media File). The subscription data availability screen  1300  can be used to prompt the patron for approval at block  1210  of the subscription data delivery process  1200 . 
       FIG. 13B  is an exemplary subscription data availability screen  1350  according to another embodiment of the invention. The subscription data availability screen  1350  can represent a screen being displayed on a display of a mobile device associated with a patron. The subscription data availability screen  1300  can be presented to a patron to inform the patron that subscription data (e.g., new Sports Highlights Media File) is being sent to the mobile device. The subscription data availability screen  1350  can be used when the mobile device or a subscription account has been configured to automatically deliver the subscription data. Automatic delivery of subscription data can be performed by the subscription data delivery process  1200  by bypassing blocks  1210  and  1212 . 
       FIG. 14  is a flow diagram of a localized data delivery process  1400  according to one embodiment of the invention. The localized data delivery process  1400  can operate to permit a patron at a location (e.g., an establishment, venue, etc.) to obtain (automatically or manually) localized data (i.e., data pertaining to the location). The localized data delivery process  1400  is, for example, performed by a local server (e.g., the local media server  602  illustrated in  FIG. 6A ) or local media system (i.e., any of the local media systems  621 ,  624 ,  628  and  632  illustrated in  FIG. 6B ). 
     The localized data delivery process  1400  begins with a decision  1402 . The decision  1402  determines whether a portable electronic device is present at the location. The location is the location of the local server or the local media server that is performing the localized data delivery process  1400 . For example, the location can be associated with a restaurant, an airport, an office complex, an amusement park, a theater, a shopping mall, and the like. Typically, the location can be considered an establishment or a venue. Once the decision  1402  determines that the portable electronic device is present at the location, data content to be delivered to the portable electronic device is determined  1404 . Next, the determined data content is delivered  1406  to the portable electronic device over a local wireless network. Note that the delivery  1406  of the determined data content is performed over a local wireless network. Hence, the delivery of the determined data content is typically only available so long as the portable electronic device remains within the range of the local wireless network. Typically, the range of a local wireless network is substantially commensurate with the establishment or venue at the location. Following the block  1406 , the localized data delivery process  1400  ends. 
     Still another aspect of the invention pertains to a user interface, namely, a graphical user interface, for a mobile device. The graphical user interface can be dependent upon the location of the mobile device. For example, if the user of the mobile device is presently at an airport, the graphical user interface being presented to the user can present information that would be of interest to the air traveler. In one embodiment, the airport includes one or more local servers that provide the information to the mobile device. Alternatively, a remotely located centralized server can provide the information to the mobile device by way of a wireless access point at the airport. Moreover, as the user moves to different geographic locations, the graphical user interface being presented can change. For example, if the user is later at a stadium watching a football game, the graphical user interface can provide information pertaining to the sport being played at the stadium. 
     Graphical User Interface 
     Still another aspect of the invention pertains to graphical user interfaces that can be provided to facilitate delivery, exchange or sharing of data. A media management application operating on the mobile device would typically provide the graphical user interface on a small display screen available on the mobile device. Several graphical user interfaces have been discussed above. 
     The graphical user interface would assist a user of the mobile device in interacting with the mobile device. For example, the user interface would facilitate navigation of locally stored media as well as remotely stored media. The user interface could provide sharing controls. These sharing controls would facilitate a user in sharing items with one or more other devices. For example, these sharing controls can enable a user to set preference settings and/or present or respond to dialogs for user interaction. For example, a preference setting could allow a user to automatically permit certain types of sharing. Such sharing can be restricted to certain users or be dependent on various conditions. As another example, a user dialog could request permission to share media content with another user or mobile device. 
     In one embodiment, the graphical user interface can also facilitate a history list. A history list can maintain a list of media items that a user of a mobile device has heard during a period of time. The history list can also record where you heard the media items. For example, if the media item was being transmitted (e.g., broadcasted) at a retail establishment by a local media server, the history list could record that the media item was heard while you were at the retail establishment. The history list can also record information such as where the user has been and when. The history list can also indicate who, what, where and when the mobile device has been interacting. The history list can also be searchable and uploadable to a computing device. 
     The user interface can also facilitate providing a shopping list. For example, a shopping list can be a virtual list that is maintained by a media device or a personal computer or a server for the benefit of a particular user. Typically, the user has a user account and the shopping list can be associated with that user account. A user of a device can interact with a user interface to add or remove items from the shopping list. The shopping list can be synchronized with various different devices associated with the user. Hence, the shopping list can be available from any of such devices. The shopping list can also facilitate ecommerce in that a purchase of items from the shopping list can be done in a simple and user-friendly manner. 
     As previously noted, a mobile device can receive data in a wireless manner from another mobile device or a wireless content server. The data being received can be stored at the mobile device and/or presented on a display screen of the mobile device. The data received can specify how information is to be displayed on the mobile device. Regardless, the information can be presented on the display as a graphical user interface. In addition, to facilitate purchase of any of the items on the interest list or on the shopping list, the user interface presented on the mobile device (or other device) can accommodate electronic commerce. 
     In one embodiment, the mobile device can support an interest list associated with the user of the mobile device. The interest list can enable the user of the mobile device to manually select items from the display screen that are of interest to the user. The user interface can also facilitate bookmarking, tagging or other user actions to indicate interest in a particular item. For example, if upon entering a business the user hears a song being played that is of interest, the user can interact with the mobile device (e.g., display screen) to indicate that a description of the song should be added to his/her interest list. The extent of the user&#39;s interest can also be noted. For example, the interest could be high such that the user wants the song to be automatically purchased for their use. On the other hand, the interest could be moderate such that the user wants to remember the song and possibly buy it at a later point in time. 
     In one embodiment, the interest list is a shopping list or a part thereof. The interest list can be shared amongst a plurality of different computing devices associated with the user. For example, if the user has a stationary computer, the interest list can be synchronized with an interest list at the mobile device. The interest list, like the history list, can be searchable and uploadable. 
     Further, the graphical user interface for the mobile device can also facilitate various user controls for data sharing. In other words, the user of a mobile device may want to control the nature and extent of data sharing that can be performed with his/her mobile device. The sharing controls, for example, can enable a user to designate items as shareable or not shareable, designate groups of persons to receive certain shareable information, set various preference settings, and/or provide permission (e.g., via dialog screens) to perform data sharing with another. 
     Although the graphical user interfaces are primarily associated with mobile devices that provide display screens, the graphical user interfaces could be used with other electronic devices (e.g., computers). 
     Remote Media Update 
     Another aspect of the invention pertains to techniques for updating media on a mobile device. In one embodiment, a remote shuffle operation can be performed with respect to media items stored on a mobile device, such as a portable media player. 
       FIG. 15A  is a flow diagram of a mobile media update process  1500  according to one embodiment of the invention. The mobile media update process  1500  is, for example, performed by a mobile media device (e.g., portable media player) when in the presence of a wireless network that facilitates Internet connectivity. 
     The mobile media update process  1500  begins with a decision  1502  that determines whether a wireless network is available. Here, the decision  1502  determines whether the mobile media device is in the presence of a wireless network such that the mobile media device can utilize the wireless network. When the decision  1502  determines that a wireless network is available, a decision  1504  determines whether automatic remote shuffle has been enabled. In one embodiment, a preference setting for the mobile media device can enable/disable automatic remote shuffle. When the decision  1504  determines that automatic remote shuffle has been enabled, a decision  1506  determines whether media depository access is available. Here, a media depository stores a plurality of media items. Typically, the media depository supports access from a plurality of users that have registered accounts with the media depository. In one embodiment, the media depository is a media server that includes data storage and/or access to a data storage device. For example, with reference to  FIG. 3 , the media depository could pertain to the central media server  301 , the personal computer  304  or the local media server  308 . 
     When the decision  1506  determines that the mobile media device has access to the media depository, a remote shuffle request is sent  1508  from the mobile media device to the media depository. Here, the mobile media device transmits the remote shuffle request to the media depository via the wireless network as well as potentially other networks, e.g., a wired network. After the remote shuffle request has been sent  1508 , a decision  1510  determines whether a media update response has been received. 
     In response to the remote shuffle request, the media depository produces a media update response after receiving and processing the remote shuffle request. The media update response contains one or more media items. The one or more media items provided with the media update response are typically dependent upon the account associated with the mobile media device or its user. For example, the account may indicate that only a subset of the generally available media items are permitted to be utilized by the account holder. In such case, the one or more media items provided in or with the media update response are limited to those media items for which the account holder is authorized. Additionally, the selection of the one or more media items to be provided in the media update response can be dependent upon a wide range of factors or criteria. For example, user ratings, play counts, genre, play history, time and location can all be used to influence those media items that are provided in the media update response. The media update response can also contain one or more instructions for the mobile media device. For example, the instructions can direct the deletion of certain or all the media items previously stored on the mobile media device. More particularly, prior to storing new media items, previously stored media items would normally be deleted to free-up data storage space for the new media items. 
     Once the decision  1510  determines that a media update response has been received, the media items stored in the mobile media device are updated  1512  in accordance with the media update response. Here, the media update response can include the media items or can include references to the media items. In any case, the media items themselves are stored in the mobile media device during the update  1512 . Following the block  1512 , the mobile media update process  1500  ends. 
     Alternatively, the mobile media device is not updated when the wireless network is unavailable, when the automatic remote shuffle is disabled or when the media depository access is not available. In such cases, the mobile update process  1500  ends without any media update. 
       FIG. 15B  illustrates an exemplary representation of an existing set  1520  of media items stored in a mobile media device according to one embodiment of the invention, and  FIG. 15C  illustrates an exemplary representation of an updated set  1520  of media items stored in the mobile media device according to one embodiment of the invention. The existing set  1520  of media items includes songs 1-7. At a subsequent point in time, when the mobile media device comes within a wireless network, then the existing set  1520  of media items can be updated to a new set  1520 ′ of media items as illustrated in  FIG. 15C , provided automatic remote shuffle is enabled and provided access to a remote media depository access is available. Here, it should be noted that in the new set  1520 ′ of media items includes songs 4 and 6 that were part of the existing  1520  of media items as well as new songs 8-12. It should be noted that songs 1-3 and 5 are not included in the new set  1520 ′. The new songs 8-12 are provided from the media repository via the media update response. In this example, the new set  1520 ′ retains a portion of the existing set  1520 . Various criterion can be used to determine which of the media items in the existing set  1520  are to be replaced when forming the new set  1520 ′. Examples of such criterion include user ratings, play counts, genre, play history, time and location. One or more of the criterion can be used in this regard. As an example, the portion of the existing set  1520  that is to be retained in the new set  1520 ′ can be selected because such songs have not been played recently, have high user ratings, or due to other reasons. 
     Multiple Access Point Discrimination 
     Still another aspect of the invention concerns discrimination of different access points associated with different establishments. In the event that a mobile device associated with a user is capable of communicating over two different wireless access points, each associated with them different establishments, the mobile device can assist the user in coupling to the appropriate wireless access point. In this regard, authentication can be utilized to distinguish the different access points. Authentication can also be utilized to filter out those access points that are not of interest to the user. For example, the user can maintain on the mobile device, a list of acceptable establishments, a list of previously utilized establishments, or a list of preferences for connection.

     The various aspects, embodiments, implementations or features of the invention can be used separately or in any combination. 
     The invention can be implemented by software, hardware or a combination of hardware and software. The invention 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, optical data storage devices, and carrier waves. 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. 
     The advantages of the invention are numerous. Different aspects, embodiments or implementations may yield one or more of the following advantages. One advantage of the invention is that data, such as media data, can be provided to a portable media device by way of a wireless network, namely, a local wireless network, or by another portable media device. The wireless data exchange can be one-way or two-way. The wireless data exchange can also be automatic or on-demand. Another advantage of the invention is that user preferences, characteristics, interests or locations can be used to customize the data being provided to a portable electronic device. Still another advantage of the invention is that delivery of data, such as media data, can be provided by a distributed network of local servers provided at various different locations. The various different locations can pertain to establishments, venues, etc. that provide a local server that supports delivery of data to portable media devices at the respective locations. 
     The many features and advantages of the present invention are apparent from the written description. Further, since numerous modifications and changes will readily occur to those skilled in the art, the invention should not be limited to the exact construction and operation as illustrated and described. Hence, all suitable modifications and equivalents may be resorted to as falling within the scope of the invention.
