Methods of maintaining a journal of media encounters between co-existing portable devices

[0001] This application claims the benefit of U.S. Provisional Application No. 60/844,142, filed Sep. 13, 2006, the entirety of which is hereby incorporated by reference herein for all purposes.

[0002] Digital media content such as audio, video, and images may be consumed by a user on a variety of devices such as personal computers, personal digital assistants, portable digital media players, gaming consoles, mobile telephones, and the like. The digital media content may be shared by users via a peer-to-peer network or a centralized file-sharing network.

[0003] Existing systems fail to provide a record of the users' experiences with the digital media content and with other users. For example, existing media players may list the digital media content that has been rendered recently to the user. These existing media players, however, fail to list the users' experiences and encounters with other users. In addition, the existing media players do not allow users to take meaningful action on the listed media content, other than to render the content again.

[0004] Embodiments of the invention create a journal of media encounters. In particular, metadata describing the media encounters by a user is stored on a computing device. Journal entries such as records are created, based on the metadata, for each of the media content items experienced during the media encounters. The journal entries are presented to a user for interaction. The journal entries include actionable elements that provide, in part, an opportunity to the user to purchase the media content items.

[0005] This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[0006] Other features will be in part apparent and in part pointed out hereinafter.

[0017] Corresponding reference characters indicate corresponding parts throughout the drawings.

[0018] Embodiments of the invention enable a user to review, purchase, flag, or otherwise manipulate digital media content received from a media system such as illustrated in FIG. 1. In an embodiment, the invention provides a journal for displaying metadata describing media encounters experienced by the user. Actions may be performed upon the journal entries such as purchasing the media content and reviewing, flagging, and deleting entries. In addition, the journal itself or a portion thereof may be sent to another user.

[0019] Referring first to FIG. 1, an exemplary block diagram illustrates a media service 102 interacting with a local communication region 104 via a network 103. In an embodiment, the local communication region 104 is a wireless network located, for example, at a retail establishment such as a coffee shop or airport. Users connect to the local communication region 104 via computing devices 106 to initiate or renew subscription licenses to the media service 102, access promotional content, update playlists, purchase media content, play games, and the like. Users may also use the local communication region 104 to access third party resources supported by an operator of the local communication region 104. The resources may include, for example, printing photographs or other data directly from the user's computing device 106 on a local network printer 108, accessing the Internet, and projecting photographs and/or video to a wireless projector or display at the retail establishment.

[0020] The media service 102 in FIG. 1 provides media content and related services to local communication regions such as local communication region 104. Users subscribe to the media service 102 to have access to the services offered by the media service 102. Subscribers to the media service 102 may pay a monthly or yearly fee for access to the media service 102. Alternatively, a pay-as-you-go model may be employed in which users pay on a per-transmission basis for access and connection to the media service 102. In yet another embodiment, the media service 102 is supported entirely or in part by advertisements inserted into transmissions from the media service 102.

[0021] The media service 102 includes a memory area 110 storing user profiles 112, media content items 114, and associated metadata 116. The user profiles 112 include subscription information 118 describing the user's subscription to the media service 102 (e.g., renewal dates and type of subscription). The media content items 114 include, but are not limited to, audio, video, and still images (e.g., full- or partial-length songs and movies, video clips or shorts, recorded television, and product commercials). In an embodiment, each of the media content items 114 each has a digital rights management policy associated therewith. In such an embodiment, transmitting the media content items 114 to the computing device 106 includes transmitting the media content items 114 with the associated digital rights management policy associated therewith to the computing device 106. A component of the digital rights management policy may direct, for example, that the transmitted media content items 114 are to be deleted or otherwise not renderable after a particular date (e.g., an expiration date). While the media content items 114 may be deleted, however, the metadata 116 associated with the media content items 114 is not deleted and remains to enable the user to purchase the media content items 114. The metadata 116 may be used as a subsequent purchase opportunity for the user to purchase the shared media content items 114.

[0022] The metadata 116 describes the media content items 114 and includes, for example, information related to album, artist, title, track, and album art. While metadata 116 is described and shown as separate from the media content items 114 in FIG. 1, some of the metadata 116 may be part of the media content items 114 (e.g., stored in a header). Further, while FIG. 1 illustrates the media content items 114 and metadata 116 as being stored in the memory area 110 local to the media service 102, the media content items 114 and metadata 116 may be stored remotely from the media service 102 and be part of a third-party system. In such an embodiment, the media service 102 has a relationship with, and access to, the third-party system to provide the media content items 114 to the local communication region 104. In addition, the metadata 116 may be augmented or supplemented when the media content items 114 are provided to the computing device 106 (e.g., with transaction details such as date and time of rendering).

[0023] The exemplary local communication region 104 illustrated in FIG. 1 includes a local media server 120 (e.g., a content distribution device) connected to the network 103 and to one or more wireless access points 122. The network 103 links the local communication region 104 to the media service 102 and, in an embodiment, to a wide area network such as the Internet. The local media server 120 includes software for connecting to the media service 102, software for connecting with computing devices 106, and, in an embodiment, a local copy of a content catalog downloaded from the media service 102. The content catalog reflects the media content items 114 that are available from the media service 102. Devices connect to the wireless access point 122 when within the local communication region 104. Exemplary devices include computing devices 106 such as computing device #1 through computing device #N, and the network printer 108. Exemplary computing devices include a mobile telephone, a personal data assistant, a portable digital media player, a laptop, and a personal computer. The computing devices 106 include any device, or any physical or logical element of such a device, separate from or included in other devices.

[0024] The local communication region 104 corresponds to any zone or network such as a media service access zone, local area network, wide area network, or personal area network, and may include any number of devices therein. For example, the local communication region 104 may include only two computing devices 106 (see FIG. 5). Wide area networks and local area networks are widely known. The personal area network represents any technology or system usable for direct communication between the computing devices 106 close to a particular person, device, or entity. An access point such as the wireless access point 122 may be part of such communication in an embodiment, but is not required to enable such communication in other embodiments. Personal area network technologies or systems may be used to connect to other local area networks or wide area networks. The reach of a personal area network may be a few meters. In an embodiment, the personal area network employs a wireless cable replacement technology. Wireless cable replacement technologies are generally identified by the air interface protocols used for communication between computing devices 106. Existing air interface protocols include BLUETOOTH, Wireless USB, and various proprietary protocols. Such air interface protocols may also be used to create wireless cable replacement topologies.

[0025] The local media server 120 in FIG. 1 includes a processor configured to execute computer-executable instructions for connecting the computing devices 106. In an embodiment, the processor operates to detect one of the computing devices 106 when the computing device 106 enters the local communication region 104 or otherwise comes within a predefined proximity of the local media server 120 or the wireless access point 122. The local media server 120 establishes a wireless connection to the detected computing device 106 and receives a user identifier from the connected computing device 106. The user identifier is used by the local media server 120 to authenticate, or enable the media service 102 to authenticate, the user of the computing device 106. Authentication includes, for example, checking the subscription information 118 or other user profile information stored in the memory area 110 of the media service 102 for the received user identifier. After authentication, the user has access to the media service 102 (e.g., media content items 114) and to one or more of the local services offered by the operator (e.g., printing). In an embodiment, the user has access to only the services offered by the media service 102 that have been paid for by the user (e.g., as specified in the user profile 112) and any additional services offered by the operator of the local communication region 104.

[0026] While connection of the computing device 106 and authentication of the user occurs automatically in an embodiment, such connection and authentication may occur only in response to a specific request from the user in other embodiments. In such embodiments, the operator broadcasts a list of services available within the local communication region 104. Responsive to a request from the user to connect, the local media server 120 connects to the computing device 106, authenticates the user, and provides access to the media service 102 and any available local services.

[0027] The local media server 120 further operates to provide access, based on the authentication status of the user (e.g., successfully authenticated or not), to the memory area 110 associated with the media service 102 for the particular user to update the subscription information 118 stored in the user profile 112 associated with the particular user, or access any other service offered by the media service 102. The local media server 120 also provides one or more of the media content items 114 and associated metadata 116 from the media service 102 to a computer-readable medium associated with the computing device 106. The one or more of the media content items 114 are selected by the operator of the local communication region 104 based on customer demand (e.g., interest, demographics, etc.). The selected media content items 114 are provided to the computing device 106 with a digital rights management policy associated therewith. For example, the policy allows three renderings of each of the media content items 114 over three days, before the media content items 114 are erased from the computing device 106 or otherwise rendered unplayable.

[0028] Aspects of the invention provide a subsequent purchase opportunity to the user to purchase the media content items 114 sent to the computed device. The purchase opportunity may occur, for example, when the user subsequently connects the computing device 106 to the Internet and views the metadata 116 associated with the provided media content items 114. The purchase opportunity occurs within in the local communication region 104, or outside the boundaries of the local communication region 104.

[0029] The operator or provider of the local communication region 104 (e.g., a retail establishment) provides access to the media service 102 for customers of the operator by acquiring a business subscription to the media service 102. Such a subscription enables the operator to uniquely brand the local communication region 104 (e.g., Joe's Coffee Shop Media Access Zone) for marketing purposes. For example, when a user enters the local communication region 104, the operator name and branding appear on the user's computing device 106. In an embodiment, the operator shares media content from the media service 102 to connected computing devices 106. The sharing may occur by streaming the media content where, upon receipt (e.g., within the predefined proximity), the computing device 106 renders the streamed media content to the user. Alternatively or in addition, the sharing may occur by downloading the media content to the computing device 106. By subscribing to the media service 102, the operator no longer needs to store local copies of the media content (e.g., compact discs, digital versatile discs) in an embodiment. Further, with access to the large repository of media content items 114 from the media service 102, the operator may offer a large variety of content to entice customers to visit or enter the local communication region 104. For example, the operator may target customers with selected media content (e.g., jazz music at a coffee shop, easy listening music at a winery, new age music at a candle shop, alternative rock at a snowboard store).

[0030] In addition, the operator is credited with a portion of the sale proceeds or otherwise rewarded by the media service 102 if the user subsequently purchases any of the downloaded media content items 114. This may be accomplished by associating an identifier with the operator, and including this identifier with the media content items 114 downloaded to the user's computing device 106. During a purchase opportunity (e.g., when the computing device 106 is connected to another computing device 106 such as a personal computer), the user views the metadata 116 associated with the downloaded media content items 114 and has the ability to purchase any of the media content items 114. In purchasing the media content items 114, the metadata 116 associated with the desired media content items 114 is sent to the media service 102 along with the identifier of the operator of the local communication region 104 in which the promotional media content items 114 were downloaded to the user's computing device 106. In this manner, the operator is identified and rewarded by the media service 102 for introducing the user to the purchased media content items 114.

[0031] Alternatively or in addition, the operator may transmit advertisements to the connected computing devices 106 within the local communication region 104. The advertisements may be designed for rendering, for example, before the content is consumed (e.g., at the beginning of music playback), after rendering completes, or at connection time. For example, when the user connects to the local communication region 104, the operator inserts a media advertisement that is presented to the user before the list of available services is displayed to the user. In another example, when the user selects an available service, the operator inserts a media advertisement that is presented to the user before the selected service is provided. In yet another example, the operator may insert advertisements at any point in the streaming or downloading of the media content to the computing device 106. Alternatively or in addition, the operator of the local communication region 104 may upload or otherwise identify selected media content items 114 to the media service 102. The media service 102 then makes the selected media content available at all or selected local communication regions related to the operator (e.g., all company-owned stores, or franchised locations).

[0032] Referring next to FIG. 2, an exemplary block diagram illustrates communication between a portable computing device 202 and a media service 204 via a journal computing device 206 and a network 208 in a media purchasing system. For example, the portable computing device 202 represents a portable digital media player and the journal computing device 206 represents a personal computer. Such a configuration occurs when the user of the portable computing device 202 leaves a local communication region such as in FIG. 1 and connects the portable computing device 202 to the journal computing device 206. While in the local communication region receiving media content items, a process executing on the portable computing device 202 records metadata representing a log of all rendered media content items including streamed content, downloaded content, broadcast radio content, and satellite content. Transaction details such as date and time of play are also recorded.

[0033] The metadata received by the portable computing device 202 from the media service 204 (or a peer device) while in the local communication region (e.g., FIG. 1) is synchronized with the journal computing device 206. The metadata is stored on the portable computing device 202 until synchronization.

[0034] The journal computing device 206 presents the synchronized metadata to the user for selection, for example, in a rich user interface. The journal computing device 206 connects to the media service 204 via a network 208 such as the Internet. In this manner, the user may purchase, via the journal computing device 206, any of the promotional media content items previously downloaded or streamed from the media service 204. Alternatively or in addition, the portable computing device 202 may establish a connection with the media service 204 exclusive of the journal computing device 206, and purchase selected media content items directly.

[0035] The journal computing device 206 includes a memory area 210. The memory area 210 stores the synchronized metadata as a plurality of records 214 such as record #1 through record #N. The records 214 comprise a journal, a history, or the like. Each of the plurality of records 214 corresponds to a media content item previously provided to the user during communication between the portable computing device 202 of the user and a content distribution device. The memory area 210 further stores actionable elements 212 such as actionable element #1 through actionable element #N. Each of the actionable elements 212 corresponds to one of the plurality of records 214. The actionable elements 212 link each of the records 214 to the media service 204 offering the corresponding media content items for purchase. In an embodiment, the actionable elements 212 include a portion of each journal entry (e.g., the title, artist name, icon, or the like) or the entire journal entry (e.g., the entire row of metadata identifying the media content item). For example, the actionable element 212 includes a hyperlinked title of a particular song.

[0036] The metadata transmitted with the media content items describes the media content items and describes the transaction. Such metadata includes, but is not limited to, album, artist, title, track, and album art. Further, the metadata includes information about the distribution of the media content items such as a date and time associated with transmission of the media content item to the portable computing device 202, the parties (e.g., portable computing device 202 and the content distribution device) involved in the transmission, identification of the media content items transferred with a particular media content item, identification of a local communication region where the transmission took place, and the like. The metadata is used to select media content items for purchase as well as to identify the party responsible for the promotional transmission of the media content item (e.g., to reward or give feedback to the responsible party). The metadata may be stored with the media content items or stored separately (e.g., in a different folder).

[0037] In operation, a processor 216 associated with the portable computing device 202 is configured to execute computer-executable instructions for communicating with the content distribution device (e.g., a peer device) upon entering a local communication region having the content distribution device therein. The media content items and associated metadata are provided to the portable computing device 202 by the content distribution device during the communication. The processor 216 further executes computer-executable instructions for connecting to the journal computing device 206 outside of the local communication region and synchronizing the associated metadata with the journal computing device 206. The processor 216 further executes computer-executable instructions for receiving a license to render one or more of the media content items associated with the metadata and for rendering at least one of the media content items to the user.

[0038] Referring next to FIG. 3, an exemplary screen shot of a user interface 302 illustrates metadata describing a plurality of media encounters. In an embodiment, the user interface 302 corresponds to a journal within a media player. The user interface 302 may be presented within the context of any application program including, for example, an Internet browser, and may also be presented as a standalone application program.

[0039] The user interface 302 in FIG. 3 lists the media content items as journal entries such as journal entry 304 shared by users during media encounters. In this example, the user had encounters with Mediadude, Jeeters, and Marky Mark. Mediadude shared songs by Annie Lennox, U2, and Green Day. Jeeters shared songs by Coldplay. Marky Mark shared songs by Green Day and Snow Patrol. Some of the songs have been flagged by the user (e.g., as songs of particular interest) such as “Talk” and “Speed of Sound” by Coldplay. The flag defines the particular media content items as being of highest value for follow up. For example, media sent from a friend that has been reviewed and enjoyed by the user is flagged by the user.

[0040] The contents of each column in the user interface 302 describe each journal entry, permit sorting and grouping, and act as actionable elements. The user interface 302 of the journal may be altered or pivoted to show various views based upon a selection of the columns (e.g., sorting). Exemplary columns are described in Table 1 below.

[0041]

TABLE 1
Exemplary Columns in the Journal User Interface.
Flag icon	Flag icon (shown if flag is set)
Track #	Track number of media content item if available
Date	Date and time of the encounter
Title	Title of media content item
Artist (Display	Artist associated with media content item
artist)
Album	Album associated with media content item
Action	Action column (e.g., Buy, Download, View Image,
	Search)
From	Person who sent you the encounter or personal tag
To	Name of the device and/or user receiving the media
	content item
Group Title	Playlist name

[0042] Actionable elements in the user interface 302 include the items in the Action column such as Download 306. Alternatively or in addition, the actionable elements include all or part of each journal entry. In an embodiment, the contents of the artist and album columns include hyperlinks. For example, if the user clicks on an artist name, the media player displays the corresponding web page for the artist. If the user clicks on an album name, the media player displays the corresponding web page for the album name.

[0043] A purchase opportunity is provided for several of the songs as shown in the Action column. The “download” action indicates that the particular media content item was streamed to the user's device, and a copy is available for purchase and downloading. The “buy” action indicates that a local copy (e.g., promotional copy) of the particular media content item is stored on the user's computing device, but the digital rights management information associated with the particular media content item indicates that a non-promotional copy of the particular media content item has not been purchased by the user. The “search” action indicates that the particular media content item has not been identified to a point where a copy may be located. Alternatively, the “search” action indicates that a copy of the particular media content item is not available for purchase from the media service.

[0044] In the exemplary user interface 302 of FIG. 3, the title, artist, and album for each media content item is shown, along with the available action and identification of the user from which the media content item was experienced. In an embodiment (not shown), the user interface 302 also displays the devices from which the media content items were received during each media encounter. The information in the user interface 302 comprises the metadata received from the portable computing device, as well as metadata from a subscription service or publisher to supplement the received metadata.

[0045] In general, the user performs various operations on the media content items from within the journal. For example, the user reviews received promotional media data (e.g., grouped by sender, date, or time), reviews streaming sessions (e.g., grouped by broadcaster, date, or time), and reviews “flagged” items (e.g., items that the user marked for future action). For each media content item, the operations include previewing a short clip of the item if a copy of the item is available to the user, purchasing and/or downloading a copy of the item, viewing received visual media (e.g., pictures or video) associated with the item, adding or removing a flag from the item, deleting a journal entry, rating each media content item, and searching for items not available from the media service to enable the user to easily purchase a copy.

[0046] In an embodiment (not shown in FIG. 3), the user interface 302 displays a current quantity of journal entries, flagged items, downloaded media content items, purchased media content items, and searches performed for media content items.

[0047] Referring next to FIG. 4, an exemplary flow chart illustrates creation of a journal of media encounters. Creating the journal documents the media encounters of a user and promotes the purchase of the media content shared during the media encounters. At 402, metadata is received from a computing device associated with a user. The metadata describes at least one media encounter experienced by the user. The media encounter represents a communication between the computing device and another computing device during which one or more media content items were exchanged between the computing devices.

[0048] A plurality of actionable elements (e.g., records, journal entries, or the like) are created at 404 for association with each of the media content items previously exchanged. The created actionable elements collectively form a journal of media encounters, and provide the user with an opportunity to purchase the media content items. The actionable elements are presented to the user at 406. Upon receipt of a selection of the actionable elements at 408, the journal and/or media content items corresponding to the selected actionable elements are manipulated accordingly at 410.

[0049] As an alternative to selecting actionable elements at 408, the user may select a particular media encounter. Journal entries corresponding to the selected media encounter are identified and the associated media content items are provided to the user for rendering. In this manner, the user is able to re-live the selected media encounter. For example, the user may want to re-live an event or just the passage of a particular day.

[0050] In an embodiment, the actionable elements and related information created at 404 are persisted as records in a database table. For example, if an entire album was received during a media encounter, the table includes individual records for each of the album tracks, with each record having the same group identifier value (e.g., JournalGroupID) to indicate a relation between the records. In addition, the album title is stored in each record (e.g., in a JournalGroupName field). If a playlist was also received, the playlist name is stored in another field. Software in aspects of the invention use the identifiers associated with each of the records in the table to match content to a media library of the computing device and the service. An exemplary schema for storing the records is shown in Table 2 below.

[0052] Embodiments of the invention may be implemented with computer-executable instructions performing operations such as illustrated in FIG. 4. The computer-executable instructions may be organized into one or more computer-executable components or modules. Aspects of the invention may be implemented with any number and organization of such components or modules. Generally, program modules include, but are not limited to, routines, programs, objects, components, and data structures that perform particular tasks or implement particular abstract data types. For example, aspects of the invention are not limited to the specific computer-executable instructions or the specific components or modules illustrated in the figures and described herein. Other embodiments of the invention may include different computer-executable instructions or components having more or less functionality than illustrated and described herein. Computer-executable instructions implementing aspects of the invention may be separate from, or included with, other computer-executable instructions executed by the computing device. For example, aspects of the invention may be implemented within a media player executing on the computing device, or as a separate program executing on the computing device.

[0053] Referring next to FIG. 5, an exemplary block diagram illustrates a peer-to-peer connection between two computing devices 502, 504 within a local communication region 505. In particular, a first computing device 502 (e.g., a content distribution device) associated with a first user establishes a peer-to-peer connection with a second computing device 504 (e.g., a portable computing device) associated with a second user. The peer-to-peer communication session represents any local, peer-to-peer physical or virtual connection between the computing devices 502, 504. The connection may be wired, wireless, or any combination thereof, and may be implemented by one or more communication protocols and/or bridging techniques for enabling communication between various protocols. Aspects of the invention as described herein are not limited to any specific protocols or network layers, but are compatible via an abstraction layer (such technique is known in the art) to support any protocol or network layer.

[0054] The first computing device 502 has a media library 506, a list of favorites and preferences 508, a proximity search and connectivity agent 510, and interfaces for connecting to other devices via, for example, wireless fidelity (WiFi) 512, BLUETOOTH 514, and other protocols or network layers 516. The media library 506 identifies the media content items stored on the first computing device 502. In an embodiment, the media library 506 is capable of resolving digital license issues such as transparently obtaining suitable license rights to playback content received during a proximity distribution transaction. The second computing device 504 has a similar set of components. Both the first and second computing devices 502, 504 broadcast their availability for media sharing connections and scan for available devices (e.g., via the proximity search and connectivity agents such as proximity search and connectivity agent 510).

[0055] The first user and second user each identify digital content distribution criteria or otherwise determine what media content to share with which other users. This information is stored, for example, in the favorites and preferences components (e.g., favorites and preferences 508). Examples of digital content distribution criteria include, but are not limited to, information regarding one or more of the following: listening habits; purchasing habits; ratings; user-defined favorites; recently purchased content; user profiles (e.g., personal information such as name, address, gender, and age); service profiles (e.g., whether a user has opted-in to participation local, peer-to-peer distribution transactions and opt-in conditions, if any); user affiliations (e.g., buddy lists); device-gathered location information; digital rights management information associated with the media content items (e.g., whether a user has the right to distribute a particular media content item, or any restrictions on such rights); and other data. The digital content distribution criteria may be combined (e.g., via Boolean operands) to create expressions for evaluation when determining whether to share media content items with a particular user. The digital content distribution criteria may also include or be affected by other criteria such as remaining memory storage and battery life of the device (e.g., do not accept large songs, and do not exhaust the battery by accepting content if the battery level is low). The set of media content items to be shared may be user-defined, auto-generated based on other factors (e.g., listening habits), or a combination of both.

[0056] The first and second computing devices 502, 504 each continually or continuously scan to detect devices within a predefined proximity. In an implementation, detecting another computing device includes implementing one or more features of a local networking service defined by the Universal Plug and Play peer-to-peer connectivity architecture (“UPNP Architecture”). Alternatively or in addition, detecting the computing device includes implementing one or more features of a service defined by the Web Services Dynamic Discovery (“WS-Discovery”) protocol. This protocol defines how services are discovered (e.g., by a simple network access protocol) on a local network. Other implementations are also possible, such as customized BLUETOOTH profiles, and Zero Configuration Networking (“ZeroConf”) techniques.

[0057] In an embodiment, detecting another computing device includes discovering, and determining the proximity of, potential participants a communication session. Proximity determination includes one or more acts, criteria, or the like for determining whether two computing devices such as computing devices 502, 504 are available for communication (e.g., within a predefined proximity or distance). Proximity may be defined as broadly or narrowly as desired, encompassing everyone/every device or only select entities or devices. Proximity may be determined on a periodic basis, and may result in identification of a set of proximate devices and/or entities. In an embodiment, the boundaries of the local communication region 505 define the limits of the predefined proximity. For example, whenever the two computing devices 502, 504 are within the local communication region 505, proximity is deemed to exist.

[0058] In another example, proximity is deemed to exist when two or more computing devices such as computing devices 502, 504 are within static or dynamic physically definable sub-regions of the local communication region 505. Examples of static, physically definable sub-regions of the local communication region 505 include particular geographical regions such as departments of retail locations (e.g., music sales departments), streets, or buildings. An example of a dynamic, physically definable sub-region of the local communication region 505 includes a predetermined maximal distance between two computing device 502, 504. Various commercially available systems and/or products may be used for location determination. Such systems and/or products are generally based on technologies such as global positioning system (GPS) technology, triangulation technology, signal strength analysis technology, time-distance-of-arrival technology, or the like.

[0059] Other circumstances under which two or more computing devices may be deemed to be in proximity are defined by one or more logical relationships between the computing devices. For example, two computing devices 502, 504 within the local communication region 505 or sub-regions thereof that have predetermined zip codes, genders, ages, preferences (e.g., music preferences), friends, or other logically relatable characteristics may be deemed to be in proximity.

[0060] After detecting each other, the first and second computing devices 502, 504 each play a particular role in an exemplary transaction. For example, the first computing device 502 may take the role of a publisher agent and expose a set of media content items from the media library 506 of the first user. The second computing device 504 may take the role of a recipient agent. The first computing device 502 (e.g., publisher agent) selects one or more media content items from the media library 506 based on the substance of the favorites and preferences component in the second computing device 504 (e.g., an evaluation of the digital content distribution criteria in the second computing device 504). For example, the first computing device 502 receives the digital content distribution criteria from the second computing device 504 upon establishing the peer-to-peer connection. Media content items from the media library 506 in the first computing device 502 that satisfy the criteria from the second computing device 504 are identified and transferred to the second computing device 504 over the established peer-to-peer connection. In addition, metadata describing the transferred media content items and describing the transaction are sent to the second computing device 504. For example, the metadata may specify that a particular song came from John's media library, and was purchased by John from ACME Music Service.

[0061] The interaction described with reference to FIG. 5 is repeated as the first and second computing devices 502, 504 individually move from one local communication region 505 to another. The criteria defined in the favorites and preferences components (e.g., favorites and preferences 508) of the two computing devices 502, 504 may be met by other devices in some local communication regions, and not met in others.

[0062] FIG. 5 shows one example of a general purpose computing device (e.g., first computing device 502 or second computing device 504) having one or more processors and a system memory. The computing device typically has at least some form of computer readable media. Computer readable media, which include both volatile and nonvolatile media, removable and non-removable media, may be any available medium that may be accessed by the computing device. By way of example and not limitation, computer readable media comprise computer storage media and communication media. Computer storage media include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically embody computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism and include any information delivery media. The modulated data signal has one or more of its characteristics set or changed in such a manner as to encode information in the signal. Wired media, such as a wired network or direct-wired connection, and wireless media, such as acoustic, RF, infrared, and other wireless media, are examples of communication media. Combinations of any of the above are also included within the scope of computer readable media.

[0063] Aspects of the invention include the computing device itself (e.g., computing device 502 or computing device 504) when programmed according to the methods and techniques described herein.

[0064] Although described in connection with an exemplary computing system environment, embodiments of the invention are operational with numerous other general purpose or special purpose computing system environments or configurations. The computing system environment is not intended to suggest any limitation as to the scope of use or functionality of any aspect of the invention. Moreover, the computing system environment should not be interpreted as having any dependency or requirement relating to any one or combination of components illustrated in the exemplary operating environments. Examples of well known computing systems, environments, and/or configurations that may be suitable for use with aspects of the invention include, but are not limited to, personal computers, server computers, hand-held or laptop devices, personal digital assistants, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, digital broadcast television recording devices, portable digital media players, gaming consoles, mobile telephones, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.

[0065] Referring next to FIG. 6, an exemplary embodiment of a computing device 602 user interface 604 identifies the media content items that are available to the computing device 602 while in a local communication region. While the computing device 602 illustrated in FIG. 6 corresponds to a portable digital media player, the user interface 604 displayed therein is applicable to any computing device (e.g., mobile telephone, personal digital assistant, etc.).

[0066] After selection of a ‘Listen to Music’ service available in the local communication region (e.g., from a local media server such as in FIG. 1 or from a peer computing device such as in FIG. 5), the user interface 604 displays a list of the media content items that are available to the computing device 602. In the example of FIG. 6, the play icon or button (e.g., triangle within a circle) next to a particular media content item indicates that media content item is available for streaming and immediate rendering on the computing device 602. The download icon or button (e.g., arrow pointing down within a circle) next to a particular media content item indicates that a promotional copy of the media content item is available for downloading and storage on the computing device 602. When the user selects a media content item that has both icons, the user is given the choice of either streaming the media content item or copying the media content item to the device 602. If only one of the icons appears next to the media content item, the operation corresponding to the appearing icon is automatically selected (e.g., “X&Y” by Coldplay will automatically be streamed upon selection of this song by the user).

[0067] Referring next to FIG. 7, an exemplary screen shot of a user interface 702 illustrates media content items sorted according to flagged or non-flagged status. In particular, a flagged items filtered view is shown. The contents of the Action column include one or more of the following options shown in Table 3 below.

[0068]

[0069] Referring next to FIG. 8, an exemplary screen shot of a user interface 802 includes a pop-up window 804 illustrating the operations available to perform on a non-flagged media content item. In an embodiment, the pop-up window 804 appears responsive to a right-click of a user interface selection device such as a mouse or touch pad while hovering over a particular journal entry in the user interface 802. The pop-up window 804 in FIG. 8 results from a user right-clicking a journal entry corresponding to a media content item that is not in the local media library but is available from the media service.

[0070] In one embodiment, the user has the capability of flagging any journal entry corresponding to a media content item that had been received or currently exists on the computing device. The flag acts as a reminder to take future action with respect to the media content item. Responsive to a request from the user to flag a particular journal entry, the user interface displays a flag near the particular journal entry or otherwise visually distinguishes the journal entry in the user interface 802.

[0071] Table 4 below describes the exemplary operations available within the journal for journal entries. The exemplary operations are shown, for example, when the right-clicking on a journal entry using a interface selection device such a mouse or touch pad.

[0072]

[0073] The search operation is available for journal entries corresponding to media content items that cannot be identified. In an embodiment, the search operation is performed by searching a media catalog associated with the media service. If a single result is returned, the content of the Action column in the user interface 802 for the journal entry is changed to Download or Buy. If two or more results are returned, the user is prompted to select the proper result. If no results are returned, the user is directed to search other catalogs (e.g., via the Internet) for the media content item.

[0074] The operations available for each journal entry are based upon the media content item associated with the selected journal entry or entries. Table 5 below shows the availability of exemplary right-click states for a journal entry.

[0076] Referring next to FIG. 9, an exemplary screen shot of a user interface 902 includes a pop-up window 904 illustrating the operations available to perform on a flagged media content item. In this instance, the media content item corresponding to the selected journal entry is not in the local media library, but is available from the media service. The journal entry has been flagged. As such, the pop-up window 904 includes a “remove flag” operation.

[0077] Referring next to FIG. 10, an exemplary screen shot of a user interface 1002 includes a pop-up window 1004 illustrating a search operation available for a media content item for which a copy is not otherwise available. In this instance, the pop-up window 1004 results from the user right-clicking a journal entry that has not been flagged, and for which the corresponding media content item is not in the library and not available from the media service. The operations of Search, Flag, and Delete are available via the pop-up window 1004 along with an option to display the known properties for the journal entry.

[0078] The following examples further illustrate aspects of the invention. In a first example, the user receives streamed media content and subsequently purchases the streamed media content. In this example, the user connects the computing device to a local communication region at a coffee shop. The user views the selected services available at the coffee shop (e.g., “The Roasted Bean”). The user previews promotional content being streamed by coffee shop over the local communication region. Metadata describing the streamed, promotional media content is copied to the user's computing device along with an identifier associated with the coffee shop (e.g., “The Roasted Bean”). The user leaves the coffee shop, thereby disconnecting from the local communication region.

[0079] At home, the user connects the computing device to a personal computer that initiates a synchronization of the metadata from the computing device to the personal computer. After synchronization completes, the user opens a journal on the personal computer and navigates to the entry for the coffee shop. All the media content that was streamed to the computing device while at the coffee shop is listed with the option to purchase the streamed media content. The user selects a few of the media content items and purchases them. The purchase request, along with the identifier of the coffee shop, is sent to the media service. The media service identifies that “The Roasted Bean” coffee shop recommended the media content items to the user, and credits a portion of the sale to the account of the coffee shop. This account of the coffee shop may be related to the business subscription that the coffee shop has with the media service, or may be a separate rewards-style account associated with the coffee shop.

[0080] In another example, the user connects the computing device to a local communication region at a coffee shop. The user views the selected services available at the coffee shop (e.g., “The Roasted Bean”). The user selects to download promotional content available on the local communication region at the coffee shop. The content and associated metadata are copied to the user's computing device (e.g., to an inbox) along with an identifier associated with the coffee shop (e.g., “The Roasted Bean”). The user may only consume the downloaded promotional media content for a time period defined by the digital rights management policy associated with the downloaded promotional media content. After the time period expires, the copies of the downloaded promotional media content stored on the computing device are deleted from the computing device or otherwise rendered not playable. The metadata, however, remains on the computing device to enable the user to subsequently purchase the media content.

[0081] The user leaves the coffee shop, thereby disconnecting from the local communication region. Outside the local communication region (e.g., on a bus), the user browses the inbox on the computing device and opens the entry associated with “The Roasted Bean”. The downloaded promotional media content is listed therein. The user selects a particular media content item and begins playback of the item.

[0082] At home, the user connects the computing device to a personal computer that initiates a synchronization of the metadata (but not the media content items) from the computing device to the personal computer. After synchronization completes, the user opens a journal on the personal computer and navigates to the entry for the coffee shop. All the media content that was copied to the computing device while at the coffee shop is listed with the option to purchase the downloaded media content. The user selects a few of the media content items and purchases them. The purchase request, along with the identifier of the coffee shop, is sent to the media service. The media service identifies that “The Roasted Bean” coffee shop recommended the media content items to the user, and credits a portion of the sale to the account of the coffee shop. As with the previous example, this account of the coffee shop may be related to the business subscription that the coffee shop has with the media service, or may be a separate rewards-style account associated with the coffee shop.

[0083] The following scenarios further illustrate operation of aspects of the invention. In a send and receive functionality scenario, TJ just bought the new Kean Album and ripped it into his media library. He then synchronizes his device with the PC media player that copies the album on to the device. Later that day TJ is at college and he bumps into his friend Dave who also happens to have a compatible device. TJ tells Dave that the new Kean Album is awesome and that he should listen to it so he sends Dave the tracks using the wireless send feature. After a few minutes, the send completes and Dave is able to listen to the Album.

[0084] Later on the same day, Dave comes home and docks his device with his PC media player client. After the synchronization completes he notices that the journal node shows that he has some new items. Dave clicks on journal and is pleased to see that the encounter he had with TJ is shown as well as all of media he received. As Dave liked the album so much he decides to click download. After a few minutes, Dave is pleased to see that he has the new Keane album in his library and starts to listen. While the tracks are playing Dave returns to the journal and deletes the entries from TJ as he no longer needs the entry.

[0085] In a flagging functionality scenario, TJ is listening to a new album on his device. During playback he hears a song he thinks his friend will like and decides to flag it to remind him to tell his friend about it the next time he sees him. Later on that day, TJ is at home and synchronizes his device with his PC media player client. As soon as the synchronization completes TJ notices that there are new journal entries showing and clicks on the Journal node. He then notices the “Personal Flag” he made earlier that morning which reminds him to send his friend an e-mail telling them about the track. After sending the e-mail, TJ deletes the entry from the journal.

[0086] The figures, description, and examples herein as well as elements not specifically described herein but within the scope of aspects of the invention constitute means for receiving the media content items and associated metadata from the content distribution device within the local communication region, and means for creating the journal on the journal computing device.
