BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to portable media devices and,
more particularly, to updating content resident on portable media
devices.
[0004] 2. Description of the Related Art
[0005] 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.
[0006] 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.
[0007] 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.RTM. media management software
offered by Apple Computer, Inc. of Cupertino, Calif. One example of
a media player is the iPod.RTM. 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.
[0008] 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.
SUMMARY OF THE INVENTION
[0009] 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.
[0010] The invention can be implemented in numerous ways, including
as a method, system, device, apparatus, or computer readable
medium. Several embodiments of the invention are discussed
below.
[0011] 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.
[0012] 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.
[0013] 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.
[0014] 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.
[0015] Other aspects and advantages of the invention will become
apparent from the following detailed description taken in

DETAILED DESCRIPTION OF THE INVENTION
[0026] 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.
[0027] Embodiments of the invention are discussed below with
reference to FIGS. 1-7. However, those skilled in the art will
readily appreciate that the detailed description given herein with
respect to these figures is for explanatory purposes as the
invention extends beyond these limited embodiments.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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).
[0043] 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.
[0044] 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.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] 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.RTM. media management software, produced
by Apple Computer, Inc. of Cupertino, Calif.
[0054] 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.
[0055] 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.
[0056] 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.
[0057] 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.
[0058] 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.
[0059] 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.
[0060] 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.
[0061] According to one embodiment, when a media player is first
connected to a host computer (or even more generally when matching
identifiers are not present), the user of the media player is
queried as to whether the user desires to affiliate, assign or lock
the media player to the host computer. When the user of the media
player elects to affiliate, assign or lock the media player with
the host computer, then a pseudo-random identifier is obtained and
stored in either the media database or a file within both the host
computer and the media player. In one implementation, the
identifier is an identifier associated with (e.g., known or
generated by) the host computer or its management module and such
identifier is sent to and stored in the media player. In another
implementation, the identifier is associated with (e.g., known or
generated by) the media player and is sent to and stored in a file
or media database of the host computer.
[0062] 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.
[0063] 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.
[0064] 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.
[0065] 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.
[0066] In another embodiment, a media player can be used with a
docking station. The docking station can provide wireless
communication capability (e.g., wireless transceiver) for the media
player, such that the media player can communicate with a host
device using the wireless communication capability when docked at
the docking station. The docking station may or may not be itself
portable.
[0067] 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.
[0068] 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.
[0069] The various aspects, embodiments, implementations or
features of the invention can be used separately or in any
combination.
[0070] The invention is preferably implemented by software, but can
also be implemented in hardware or a combination of hardware and
software. The invention can also be embodied as computer readable
code on a computer readable medium. The computer readable medium is
any data storage device that can store data which can thereafter be
read by a computer system. Examples of the computer readable medium
include read-only memory, random-access memory, CD-ROMs, DVDs,
magnetic tape, optical data storage devices, and carrier waves. The
computer readable medium can also be distributed over
network-coupled computer systems so that the computer readable code
is stored and executed in a distributed fashion.
[0071] 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.
[0072] The many features and advantages of the present invention
are apparent from the written description and, thus, it is intended
by the appended claims to cover all such features and advantages of
the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, the invention
should not be limited to the exact construction and operation as
illustrated and described. Hence, all suitable modifications and
equivalents may be resorted to as falling within the scope of the
invention.
