The present invention relates to portable media devices and, more particularly, to updating content resident on portable media devices.
Synchronization operations have been conventionally performed between portable devices, such as Personal Digital Assistants (PDAs) and host computers, to synchronize electronic files or other resources. For example, these files or other resources can pertain to text files, data files, calendar appointments, emails, to-do lists, electronic rolodexes, etc. However, such synchronization schemes have traditionally used filenames and modification dates to determine whether files need to be copied between the devices. These synchronization schemes can be largely automated but nevertheless have to be initiated manually while the devices are connected.
In the case of media players, such as MP3 players, files are typically moved between a host computer and a media player through use of a drag and drop operation, like is conventionally done with respect to copying of a data file from a Windows desktop to a floppy disk. Hence, the user of the media player manually performs the synchronization for individual media items. As a consequence, synchronization tends to be tedious and time consuming for users.
More recently, media players have been able to be synchronized with a host computer when a bus connection over a cable is made. Here, the synchronization can be automatically initiated by the host computer when the cable is connected between the host computer and the media player. A user of the host computer can also manually initiate synchronization so long as the cable is connected between the host computer and the media player. In either case, initiation of synchronization is performed by the host computer, which corresponds to a “push” model. Typically, the host computer will operate a media management application that facilitates the management of media and well as synchronization of some or all of such media to a media player. One example of a media management application is the iTunes® media management software offered by Apple Computer, Inc. of Cupertino, Calif. One example of a media player is the iPod® media device also offered by Apple Computer, Inc. of Cupertino, Calif., which has the capability to be synchronized with a host computer over a cable. One disadvantage with synchronization over a cable is that the cable connection must be made. A user can often forget to connect the cable. Without the cable connection, the synchronization will not occur. A user can use a docking station to simplify the connection process. However, the user can still forget to couple the media player into the docking station. Further, the cable is normally relatively short in length, such as a few feet (e.g., 2-6 feet), so the media player must be brought within a few feet of the host computer for synchronization to occur.
Thus, there is a continuing need for improved techniques to update (e.g., synchronize) content on media players when remotely located from a host computer.
The invention relates to interaction between a host device (e.g., host computer) and a portable media device (e.g., media player). According to one embodiment of the invention, interaction between the host device and the portable media device can be performed over a network. The network can include wired and/or wireless components. The network can also be local, regional or global in geographic coverage. The interaction over the network can be initiated by the portable media device, manually or automatically, so as to request a content update from the host device. For example, a user of the portable media device can interact with a user interface thereof to manually request a content update from the host device. As another example, the portable media device can automatically (i.e., without user input) request a content update from the host device. Regardless, in response to the requested content update, updated content is received at the portable media device from the host device, provided a network connection between the portable media device and the host device is available through the network. Typically, but not exclusively or necessarily, the updated content is media data.
As a method for updating content resident on a portable media device from a media host device over a network, one embodiment of the invention includes at least the acts of: receiving a user request to update the content resident on the portable media device from content available on the media host device; determining whether the portable media device presently has network access to the media host device; sending a content update request to the media host device when it is determined that the portable media device presently has network access to the media host device; receiving content from the media host device in response to the content update request; and storing the content received from the media host device onto the portable media device.
As a method for updating content resident on a portable media device from a media host device over a network, another embodiment of the invention includes at least the acts of: determining whether the portable media device presently has network access to the media host device; determining whether the content resident on the portable media device is to be updated from content available on the media host device when it is determined that the portable media device presently has network access to the media host device; sending a content update request to the media host device when it is determined that the content resident on the portable media device is to be updated from content available on the media host device; receiving content from the media host device in response to the content update request; and storing the content received from the media host device onto the portable media device.
As a computer readable medium including computer program code for updating content resident on a portable device from a host device over a network, one embodiment of the invention includes at least: computer program code for determining whether content resident on the portable device is to be updated from content available on the host device; computer program code for determining whether the portable device presently has network access to the host device; computer program code for sending a content update request to the host device when it is determined that not only does the portable device presently have network access to the host device but also it is determined that the content resident on the portable device is to be updated; computer program code for receiving content from the host device in response to the content update request; and computer program code for storing the content received from the host device onto the portable device.
As a portable media device capable of updating content resident thereon from a media host device over a network, one embodiment of the invention includes at least: a data storage device that stores content; and a processor for storing, accessing and presenting the stored content from the data storage device. The processor being configured to: (i) determine whether content resident on the portable media device is to be updated from content available on the media host device; (ii) determine whether the portable media device presently has network access to the media host device; (iii) send a content update request to the media host device when it is determined that not only does the portable media device presently have network access to the media host device but also it is determined that the content resident on the portable media device is to be updated; (iv) receive content from the media host device in response to the content update request; and (v) store the content received from the media host device into the data storage device.

FIG. 1 is a block diagram of a network media system 100 according to one embodiment of the invention. The network media system 100 supports exchange of digital data between different media devices over a network. The network media system 100 includes a media host device 102 (MHD). The media host device 102 couples to a wired network 104. The wired network 104 is a data network, such as a local area, wide area or global network. In one embodiment, the global network can correspond to the World Wide Web or the Internet. The media host device 102 operates a media management application (MMA) 106. The media management application 106 operates to assist a user of the media host device 102 in managing digital data, namely, media items, that reside on or are available to the media host device 102. The digital data can also include non-media data such as text files, database data, data files, calendar appointments, emails, to-do lists, contacts, etc.
The network media system 100 also includes a media store server 108. The media store server 108 provides an online commerce center for access to digital data, namely, media items. By interacting with the media store server 108 via the wired network 104, the media host device 102 or other devices can browse, preview, play or purchase media items. Additional details on an online commerce center are provided in U.S. Patent Publication 2005/0021478 A1, which is hereby incorporated herein by reference.
The network media system 110 also supports a portable media device 110. The portable media device 110 can wirelessly couple to the wired network 104 through a wireless network 112. The wireless network 112 is typically limited to a geographic region and so long as the portable media device 110 is within that geographical region, the portable media device 110 can normally connect to the wireless network 112 and then connect via the wired network 104 to the media host device 102 or the media store server 108. To facilitate the network connection, the portable media device 110 stores the network address of the media host device 102 and/or the media store server 108.
By connecting the portable media device 110 to the media host device 102 or the media store server 108 through the wireless network 112 and the wired network 104, the portable media device 110 can request updated content from the media host device 102 or the media store server 108. Updated content is digital data that is to be provided to the portable media device 110. In one embodiment, the updated content can be newly available data at the media host device 102, or simply different data from the media host device 102. In order for the portable media device 110 be able to connect through the one or more networks 104, 112 to the associated media host device 102, the media host device 102 must be activated. In other words, the media host device 102, e.g., a personal computer, needs to be powered-on, though it could be sleeping or in a low-power mode.
The portable media device 110 can be remotely located, even in a different country, as compared to the media host device 102 or the media store server 108, yet the portable media device 110 can request and receive updated content. The updated content can be obtained from the media store server 108 or the associated media host device 102 and delivered to the portable media device 110 over the wired network 104 and the wireless network 112. In another embodiment, the portable media device 110 could also receive, transmit or exchange digital data with another portable media device supported by the network media system 100. In one implementation, the portable media device 110 sends commands over the network 104, 112 that are performed on the media host device 102 or the media store server 108. In another implementation, the portable media device 110 can include a media management application to access and retrieve media stored remotely, such as on the media host device 102.
Although not illustrated in FIG. 1, the network media system 100 typically supports a plurality of different portable media devices. Hence, a plurality of portable media devices can couple to the wireless network 112. Likewise, the network media system 100 can also include another wireless network 114, which can serve a different geographic region. The wireless network 114 can also support a plurality of different portable media devices. Still further, the network media system 100 can also support a plurality of different media host devices. Often, a particular one of the portable media devices will be associated with a particular one of the media host devices. For example, a first user may be the owner or user associated with the media host device 102 as well as the portable media device 110. As such, the media host device 102 and the portable media device 110 would normally be associated with one another. More generally, a particular media host device may host media for one or more portable media devices.
According to one aspect of the invention, a portable media device, when in the presence of a suitable wireless network, is able to interact with its associated media host device. As a result, the portable media device can initiate an update to its stored content. The update to the stored content on the portable media device can cause different content to be stored on the portable media device. The updated content can be obtained from a media host, such as a media store server that provides an online media store, a media host device, or another portable media device. For example, even though the portable media device is remotely located from a media host, the portable media device (or its user) might request and receive a different playlist, song, video, photo album or podcast.
FIG. 2 is a flow diagram of a content update process 200 according to one embodiment of the invention. The content update process 200 is, for example, performed by a portable media device, such as the portable media device 110 illustrated in FIG. 1.
The content update process 200 begins with a decision 202 that determines whether a content update should be performed. When the decision 202 determines that a content update should not be performed, the content update process 200 waits until a content update is to be performed. Once the decision 202 determines that a content update is to be performed, a decision 204 determines whether network access to a media host device is available. When the decision 204 determines that network access to the media host device is not available, the content update process 200 can return to the block 202 or can await the availability of network access.
On the other hand, when the decision 204 determines that network access to the media host device is available, a content update from the media host device is requested 206. A decision 208 then determines whether a content update has been received from the media host device. When the decision 208 determines that a content update has not yet been received, the content update process 200 awaits such an update. Once the decision 208 determines that a content update has been received, the received content is stored 210 on the portable media device, thereby updating the content on the portable media device. Following the block 210, the content update process 200 is complete and ends.
FIGS. 3A and 3B are flow diagrams of a manual content update process 300 according to one embodiment of the invention. The manual content update process 300 is, for example, performed by a portable media device, such as the portable media device 110 illustrated in FIG. 1.
The manual content update process 300 begins with a decision 302. The decision 302 determines whether a content update request has been received. Here, the content update request is caused by a user action with respect to the portable media device. Hence, when the decision 302 determines that a content update request has not been received, the manual content update process 300 awaits such a request. In other words, the manual content update process 300 is invoked when a content update request is received from a user.
Once the decision 302 determines that a content update request has been made, a decision 304 determines whether a wireless network is available to the portable media device. When the decision 304 determines that a wireless network is not available, then a network unavailable message is displayed 306 on the portable media device. Following the block 306, the manual content update process 300 returns to repeat the decision 302 so as to process a subsequent content update request.
Alternatively, when the decision 304 determines that a wireless network is available, network access information for a media host device (MHD) is obtained 308. Presumably, the media host device was previously associated with the portable media device. Then, connection (i.e., network connection) from the portable media device to the media host device is attempted 310. Here, the connection would be through one or more networks, whether wireless or wired. Next, a decision 312 determines whether the attempted connection has been established. When the decision 312 determines that a connection has been established, authentication information can be sent 314 to the media host device. In one embodiment, the authentication information is previously stored on the portable media device and is retrieved and sent 314 to the media host device. As an example, the authentication information can pertain to a device identifier for the portable media device. The device identifier can be unique (e.g., GUID) or pseudo-unique. The device identifier can also be encrypted to provide secure delivery over the network(s). Following the block 314, a decision 316 determines whether authentication has been successful. Here, the media host device, upon receiving the authentication information, attempts to authenticate the portable media device. In one implementation, the media host device stores an access control list that identifies those devices entitled to access the media host device over a network. For example, the access control list can include device identifiers corresponding to those devices (e.g., portable media devices) that are authorized. When the decision 316 determines that authentication has been unsuccessful, as well as when the decision 312 determines that a connection has not been established, an access unavailable message can be displayed 318 on the portable media device. Following the block 318, the manual update process 300 returns to repeat the decision 302 and subsequent blocks.
On the other hand, when the decision 316 determines that the portable media device has been successfully authenticated, the manual content update process 300 continues. Namely, a content update request is sent 320 from the portable media device to the media host device. A decision 322 then determines whether content has been received from the media host device in response to the content update request. When the decision 322 determines that content has been received, the content received is stored 324 to the portable media device (PMD).
In one embodiment, the portable media device can also receive content update instructions from the media host device. The content update instructions are instructions that can be understood and carried out by the portable media device. For example, the content update instructions can cause the portable media device to delete certain existing content from the portable media device, so as to free-up storage space for the newly received content. The content update instructions could also inform the portable media device on how or where to store the newly received content.
After the content received has been stored 324, a decision 326 determines whether the update is completed. When the decision 326 determines that the update is not completed, the manual content update process 300 returns to repeat the decision 322 so that additional content can be received and stored. When the decision 326 determines that the update is completed, then the manual content update process 300 returns to repeat the decision 302 so that subsequent content updates can be similarly processed.
Additionally, when the decision 322 determines that content has not been received, a decision 328 can determine whether the connection to the media host device has been lost. When the decision 328 determines that the connection to the media host device has not been lost, the manual content update process 300 returns to repeat the block 322. Alternatively, when the decision 328 determines that the connection has been lost, the content update is cancelled 330 and then the manual content update process 300 returns to the decision 302 so that subsequent content updates can be similarly processed.
FIG. 4 is a flow diagram of an automatic content update process 400 according to one embodiment of the invention. The automatic content update process 400 is, for example, performed by a portable media device, such as the portable media device 110 illustrated in FIG. 1. The automatic content update process 400 begins with a decision 402 that determines whether a wireless network is available to the portable media device. When the decision 402 determines that a wireless network is not available, the automatic content update process 400 waits for network availability. Optionally, a network unavailable indication can be displayed on the portable media device to inform the user of the portable media device of network unavailability.
Alternatively, when the decision 402 determines that a wireless network is available, a decision 404 determines whether an automatic update should be performed at this time. The automatic update can be influenced by one or more criteria, including whether automatic update is enabled by a user preference, by time since last update, and/or by various other update policies. Update policies are discussed below and can vary widely with implementation. As examples, update policies can be dependent on one or more of: (i) available bandwidth through the network, (ii) available storage capacity of the portable media device, (iii) network connection bandwidth, (iv) battery level, (v) quantity of data (e.g., content size), etc. In any case, once the decision 404 determines that an automatic update is not to be performed at this time, the automatic content update process 400 returns to repeat the decision 402; however, a delay can be imposed prior to again performing the decision 402. On the other hand, when the decision 404 determines that an automatic update should be performed at this time, the operations 308-328 discussed above with respect to FIGS. 3A and 3B can be performed at block 406. Thereafter, the automatic content update process 400 returns to repeat the decision 402 so that subsequent automatic content updates can be similarly processed, though a delay can be imposed prior to again performing the decision 402.
One form of content update between different electronic devices is known as synchronization. In the course of updating (e.g., synchronizing) content at a portable media device with content from an associated media host over a network, one or more screens can be presented on a display of the portable media device. These screens can be provided for various purposes, for example: (1) to initiate synchronization, (2) to configure synchronization parameters; and/or (3) to select content for synchronization. FIGS. 5A-5C illustrate several representative screens that could be presented on a display of a mobile media device.
FIG. 5A is a representative menu screen 500 according to one embodiment of the invention. The menu screen 500 can be presented on a display of a portable media device. As shown in FIG. 5A, the menu screen 500 includes a list of selectable items. One of the selectable items is “Sync Now” item 502 and another of the selectable items is “Settings” 504. The user of the portable media device can interact with a user interface so as to select the “Sync Now” item 502. By selecting the “Sync Now” item 502, the user is requesting that the portable media device now be synchronized with an associated media host device. In other words, the selection of the “Sync Now” item 502 from the menu screen 500 operates as a manual request for synchronization of the portable media device with the associated media host device. As an example, in response to the selection of the “Sync Now” item 502, the manual content update process 300 illustrated in FIGS. 3A and 3B can be performed.
FIG. 5B is a representative synchronization (sync) settings screen 520 according to one embodiment of the invention. The sync settings screen 520 can be presented on a display of a portable media device. For example, upon selection of the “Settings” item 504 from the menu screen 500 illustrated in FIG. 5A, a settings screen (not shown) can be presented on the display of the portable media device. Presumably, one option from the settings screen would be for setting synchronization options. Selection of the option pertaining to synchronization options causes the sync settings screen 520 to be displayed. The sync settings screen 520 includes representative settings that a user of the portable media device can make to influence how synchronization is to be performed. In particular, the sync settings screen 520 includes an enable/disable selector 522. The enable/disable selector 522 allows the user to enable or disable automatic synchronization. In the event that automatic synchronization is enabled, the synchronization settings window 520 allows the user to further specify one or more media types 524 to be synchronized as well as one or more synchronization policies 526 to be applied. As shown in FIG. 5B, the media types 524 that can be selected or deselected include Music, Video, Contacts and Podcasts. The synchronization policies 526, as shown in FIG. 5B, can be individually determined for an associated media type. In other words, each media type 524 can utilize a separate synchronization policy 526. On the other hand, the synchronization policies 526 can be used to apply to all media types that are enabled and thus apply cumulatively to all such media types. In FIG. 5B, the exemplary synchronization policies 526 that are shown as being selected for the corresponding media types 524 are Always, High Bandwidth, Always, and Space Available, respectively, for the media types Music, Video, Contacts, and Podcasts. The synchronization policy denoted “Always” indicates a policy to always synchronize this media type. The synchronization policy denoted “High Bandwidth” indicates a policy to synchronize this media type only if high bandwidth network connectivity is available. The synchronization policy denoted “Space Available” indicates a policy to synchronize this media type if the recipient device has adequate available space. Although the sync settings window 520 is described as associated with automatic synchronization, it should be understood that the media types and synchronization policies could also be used to influence the nature of manual synchronization.
FIG. 5C is a representative content selection screen 540 according to one embodiment of the invention. The content selection screen 540 presents to a user selectable list of available content that can be retrieved and supplied to the portable media device. In other words, the user can select some or all of the available content being presented in the content selection screen 540. More particularly, the content identified in the content selection screen 540 can be categorized under various categories of media, including Available Playlists 542, New Podcasts 544, New Videos 546 and New Songs 548. In this representative content selection screen 540, the Available Playlists 542 include one or more different playlists that can be individually selected for delivery to the portable media device. The New Podcasts 544 include one or more new podcasts that can be individually selected for delivery to the portable media device. The New Videos 546 include one or more new videos that can be individually selected for delivery to the portable media device. The New Songs 548 include one or more new songs (or albums) that can be individually selected for delivery to the portable media device. In addition, the content selection screen 540 can include additional user interface controls (not shown) that allow a user to select all content, to select all content of a particular grouping or media type, to select content based on preferences or policies, etc. Once the desired content has been selected, the user can select a “Get Content” control 550. Upon selection of the “Get Content” control 550, the selected content is requested from the associated media host device.
In one embodiment of the invention, the portable media device does not need to include a media management application. In such case, the portable media device, to the extent it needs assistance of a media management application, makes use of the media management application residing on the associated media host device. In another embodiment, the portable media device includes a media management application. By operating the media management application on the portable media device, the ability of the user of the portable media device to manage their media items is substantially improved.
In one implementation, the content update processing (e.g., synchronization processing) at a media host device (e.g., personal computer) can utilize an application (e.g., media management application) resident on the host computer to perform the comparison and updating of the media items and their attributes between the media host device and the portable media device. One such application is iTunes® media management software, produced by Apple Computer, Inc. of Cupertino, Calif.
FIG. 6 is a block diagram of a media management system 600 according to one embodiment of the invention. The media management system 600 includes a host computer 602 (or media host device) and a media player 604 (or portable media device). The host computer 602 is typically a personal computer. The host computer, among other conventional components, includes a management module 606 which is a software module. The management module 606 provides for centralized management of media items (and/or playlists) not only on the host computer 602 but also optionally on the media player 604. More particularly, the management module 606 manages those media items stored in a media store 608 associated with the host computer 602. The management module 606 also interacts with a media database 610 to store media information associated with the media items stored in the media store 608.
The media information pertains to characteristics or attributes of the media items. For example, in the case of audio or audiovisual media, the media information can include one or more of: title, album, track, artist, composer and genre. These types of media information are specific to particular media items. The media information can also indicate one or more of: time purchased, time downloaded, how often played, rating, etc. In addition, the media information can pertain to quality characteristics of the media items. Examples of quality characteristics of media items can include one or more of: bit rate, sample rate, equalizer setting, volume adjustment, start/stop and total time.
Still further, the host computer 602 includes a play module 612. The play module 612 is a software module that can be utilized to play certain media items stored in the media store 608. The play module 612 can also display (on a display screen) or otherwise utilize media information from the media database 610. Typically, the media information of interest corresponds to the media items to be played by the play module 612.
The host computer 602 also includes a communication module 614 that couples to a corresponding communication module 616 within the media player 604. A network connection 618 through one or more networks couples the communication modules 614 and 616. Hence, even when the media player 604 is remotely located from the host computer 602, communication between the devices is possible over the network connection 618.
The media player 604 also includes a media store 620 that stores media items within the media player 604. The media items being stored to the media store 620 can be received over the network connection 618 from the host computer 602. More particularly, the management module 606 sends all or certain of those media items residing on the media store 608 over the network connection 618 to the media store 620 within the media player 604. Additionally, the corresponding media information for the media items that is also delivered to the media player 604 from the host computer 602 can be stored in a media database 622. In this regard, certain media information from the media database 610 within the host computer 602 can be sent to the media database 622 within the media player 604 over the connection or link 618. Still further, playlists identifying certain of the media items can also be sent by the management module 606 over the network connection 618 to the media store 620 or the media database 622 within the media player 604.
Furthermore, the media player 604 includes a play module 624 that couples to the media store 620 and the media database 622. The play module 624 is a software module that can be utilized to play certain media items stored in the media store 620. The play module 624 can also display (on a display screen) or otherwise utilize media information from the media database 622. Typically, the media information of interest corresponds to the media items to be played by the play module 624.
As previously noted, synchronization is a form of media management. The synchronization between devices can be restricted so as to prevent automatic synchronization when the host computer and media player do not recognize one another.
FIG. 7 is a block diagram of a media player 700 according to one embodiment of the invention. The media player 700 includes a processor 702 that pertains to a microprocessor or controller for controlling the overall operation of the media player 700. The media player 700 stores media data pertaining to media items in a file system 704 and a cache 706. The file system 704 is, typically, a storage disk or a plurality of disks. The file system 704 typically provides high capacity storage capability for the media player 700. However, since the access time to the file system 704 is relatively slow, the media player 700 can also include a cache 706. The cache 706 is, for example, Random-Access Memory (RAM) provided by semiconductor memory. The relative access time to the cache 706 is substantially shorter than for the file system 704. However, the cache 706 does not have the large storage capacity of the file system 704. Further, the file system 704, when active, consumes more power than does the cache 706. The power consumption is often a concern when the media player 700 is a portable media player that is powered by a battery (not shown). The media player 700 also includes a RAM 720 and a Read-Only Memory (ROM) 722. The ROM 722 can store programs, utilities or processes to be executed in a non-volatile manner. The RAM 720 provides volatile data storage, such as for the cache 706.
The media player 700 also includes a user input device 708 that allows a user of the media player 700 to interact with the media player 700. For example, the user input device 708 can take a variety of forms, such as a button, keypad, dial, etc. Still further, the media player 700 includes a display 710 (screen display) that can be controlled by the processor 702 to display information to the user. A data bus 711 can facilitate data transfer between at least the file system 704, the cache 706, the processor 702, and the CODEC 712.
In one embodiment, the media player 700 serves to store a plurality of media items (e.g., songs) in the file system 704. When a user desires to have the media player play a particular media item, a list of available media items is displayed on the display 710. Then, using the user input device 708, a user can select one of the available media items. The processor 702, upon receiving a selection of a particular media item, supplies the media data (e.g., audio file) for the particular media item to a coder/decoder (CODEC) 712. The CODEC 712 then produces analog output signals for a speaker 714. The speaker 714 can be a speaker internal to the media player 700 or external to the media player 700. For example, headphones or earphones that connect to the media player 700 would be considered an external speaker.
The media player 700 also includes a network/bus interface 716 that couples to a data link 718. The data link 718 allows the media player 700 to couple to a network. The data link 718 can be provided over a wired connection or a wireless connection. In the case of a wireless connection, the network/bus interface 716 can include a wireless transceiver.
In yet another embodiment, a larger portable device, such as a vehicle, bag or case, can house or contain the portable media device and also optionally provide the network access.
The media items of emphasis in several of the above embodiments can be audio items (e.g., audio files or songs, audiobooks, and/or podcasts), videos (e.g., movies) or images (e.g., photos). The media items can also be multimedia items. The media items can also be playlists of media items.
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 a user is able to manage digital data (e.g., media data) residing on a media player from anywhere a network connection is available. Typically, the media player would access a global data network (e.g., the Internet) via a wireless network and then access a host device (e.g., host computer) also connected to the global computer network to obtain updated digital data therefrom. Another advantage of the invention is that the media player, or its user, can initiate update of digital data for the media player. The user of the media player thus does not have to return to the host device to initiate an update; instead, the media player, or its user, can remotely initiate an update. Still another advantage of the invention is that the media player, or its user, can set policies that are used in determining how or when digital data is to be updated.
