Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is a Continuation-In-Part and U.S. National Phase entry of PCT/GB2009/001061 filed Apr. 24, 2009, and claims priority to Great Britain Patent Application No. 0807590.5 filed Apr. 25, 2008, and Great Britain Patent Application No. 0821411.6 filed Nov. 24, 2008, each of which is incorporated herein by references hereto. 
     FIELD OF THE INVENTION 
     The present invention relates to a system, apparatus and method for synchronising data between a portable data storage device and a data store, which is generally provided by a content server. 
     BACKGROUND OF THE INVENTION 
     Portable data storage devices capable of holding, recording and/or playing digital content are becoming more prevalent. For example, it is now not uncommon for a mobile telephone to be able to record and/or play back video, take and/or display pictures, record and/or play back sound files including MP3 files and the like; download and/or upload files from the Internet or other networks. This is equally true of other mobile devices such as cameras, MP3/MP4 players (a generic term used to refer to portable music/video playing devices such as the iPod™, or the like). 
     There is often a desire for a user to move data onto and/or from the portable data storage device. This data movement can be to take newly generated data (such as a photograph, video, etc.) off the device in order to store it for archival purposes or share it with a set of users through a common data storage, and/or to add new data to the device or subsequent playback (for example the addition of a new music file which may be a song, a podcast, etc.), a video, etc. 
     Such movement of data can typically occur via a number of mechanisms. For example, some devices may be connected to a personal computer such as a PC, Apple™, etc. which subsequently performs the data movement. Other devices, can move data via telecommunication networks such as a GSM (Global System for Mobile communications), UMTS (Universal Mobile Telecommunications System) network or the like. Yet further devices can communicate with wireless networks such as a WIFI (IEEE 802.11x where x is any number of letters) network, or the like. 
     However, telecommunications networks such as GSM, UMTS networks and the like are not intended to transmit high bandwidth data such as video, music, etc. As such the quality of data received on the data storage device may not be suitable to view in what is generally termed real time. Further, such networks are expensive to use and as users can be faced with high usage costs to transfer data across them. 
     Also, movement of data to and/or from a portable device typically requires significant user intervention which often deters users from moving the data. As such, newly generated data is at risk of being lost because users may tend to leave the data only on the mobile device and as such if the device is lost or broken then the data is gone. Alternatively, the memory of a device may become full or the number of files may become excessive making data hard to access as users may not remove files because it is hard to manage data on the restricted user interfaces of typical portable data storage devices 
     Further, these devices do not offer a way to share the data with a set of users because of limited or no networking capability (e.g. digital photo camera, mp3 player, thumbdrive) unless the user transfers the data to a personal computer and then to it&#39;s final destination where the content will be shared. (e.g. a web based photo album, a video sharing network such as YouTube™). 
     SUMMARY OF THE INVENTION 
     According to a first aspect of the invention there is provided a data synchronisation system comprising:
         a data storage device;   a synchronisation device arranged to synchronise at least content data stored on the data storage device;   a control server arranged to control operation of the synchronisation device; and   one or more content servers;   wherein the synchronisation device is arranged to have connected thereto the data storage device and is also arranged to establish a connection to the control server and/or the content server via a network;   the control server is arranged to send connection data to the synchronisation device which determines to which content server the synchronisation device establishes a connection; and   the synchronisation device being further arranged to process the connection data and establish a connection with the or each content server based upon the connection data and, further, dependent upon the connection data to perform at least one of:
           i: download content data from the content server;   ii. upload content data received from the content server to the data storage device;   iii. download content data from the data storage device; and   iv. upload content data received from the data storage device to the content server.   
               

     Embodiments of such a system are believed advantageous as they store the connection data remotely from the data storage device and the synchronisation device. As such, data security may be enhanced. Such a system may allow a user to conveniently share his/her data and/or update content on the data storage device. This may occur irrespective of his/her location and/or data storage device that is connected to the synchronisation device. 
     Further, moving functionality from the synchronization device to the control server may reduce complexity of the programming required within that device. 
     A further advantage of such a system might be that it can also reduce the amount of waste during a user upgrade of his/her data storage device (eg a user obtains a new mobile telephone or the like) since processing circuitry within the synchronisation device is shared by multiple data storage devices can be reused with the new data storage device. As such, the processing circuitry within the data storage device may be simplified. 
     Conveniently, the synchronisation device is arranged to obtain a device identifier from the data storage device. 
     Conceivably, the data storage device may not comprise a unique device identifier. The synchronization device may be arranged to place a device identifier on such a data storage device. For example, the synchronization device may be arranged to write a file, or the like, to the data storage device containing the device identifier. 
     In some embodiments, if it is to write the device identifier to the data storage device, the synchronization device may be arranged to obtain the device identifier from the control server. Alternatively, the synchronization device may be arranged to generate the device identifier. 
     The synchronisation device may be arranged to transmit one of the device identifier and a synchronisation device identifier to the control server which is arranged to send connection data tailored to at least one of the identifiers. As such, that the connection data may be thought of as a profile for the data storage device and/or the synchronisation device which can be retrieved using a relevant identifier. 
     The control server may also be arranged to generate capability data which provides the capabilities of the data storage device associated with the device identifier. In some embodiments, the capability data may be provided as part of the connection data. 
     Generally, the capability data provides the capabilities of the data storage device that generated the device identifier. In such an embodiment, the synchronisation device may be arranged to: download content data from a content server in a first data format, adapt the content data according to the device capabilities held in the capability data and upload the adapted content to the data storage device. Such an arrangement is advantageous because it allows the data storage device to download content data that is held in a format that it cannot use and subsequently have the content adapted in order that it can use the content data. As such, the system may be arranged to process and transfer content data based on what is known about the data storage device and/or the user of the data storage device, in effect translating data between source and destination. 
     The synchronisation device may be arranged to upload content data from the data storage device, adapt the downloaded content data according to the capability data, to be compatible with the destination content server as specified in the connection data. 
     The system, and possibly the control server in particular, may be arranged to suggest content for the data storage device. This may be thought of as proactively adapting data by suggesting content. 
     In additional, or alternative embodiments, the system, and possibly the synchronisation device in particular, may be arranged to adapt content as it is sent and/or received and such an arrangement may be thought of as reactively adapting content. 
     Proactively adapting content may mean that the system allows the user to copy one or more content server subscriptions to a second or new data storage device during which process, the system may or may not adapt the or each setting to cater for the differences in capabilities between data storage devices with or without assistance from a user. In an example, the user may copy a YouTube™ channel subscription from a mobile phone to a PSP™ (Play Station Portable) without having to specify the differences in file format and screen size as the system may adapt this automatically. In a further example, should a user upgrade from an older digital picture frame to one that can play video and audio, the system may proactively suggest new content to add to the existing subscriptions. 
     Some of the embodiments may be arranged to perform each of steps i to iv. However, in some embodiments, whilst the synchronisation device may be arranged to perform each of these steps i to iv, they may not be performed at once. For example, data may only be moved from the data storage device toward the content server when content data is available on the data storage device. Likewise data may only be moved from the content server toward the data storage device when there is content data available on the content server. 
     Steps i and ii may be performed concurrently, or at least substantially concurrently. However, in some embodiments data downloaded from the content server may be buffered within the synchronisation device before being uploaded to the data storage device. 
     Alternatively, or additionally, steps iii. and iv may be performed concurrently, or at least substantially concurrently. However, in some embodiments, data downloaded from the data storage device may be buffered within the synchronisation device before being uploaded to the content server. 
     The data storage device may be connected to the synchronisation device by a first data connection which may be wired and/or wireless. 
     For example, the synchronisation device may comprise a first data connection which may be arranged to connect to USB (Universal Serial Bus), Firewire, Ethernet (including Power over Ethernet). Embodiments in which the first network connection between the data storage device and the synchronisation device are wired can be advantageous as they may allow the data storage device to be charged as it is being synchronised. 
     Alternatively, or additionally, the first data connection may be a wireless connection such as WIFI (IEEE 802.11x), Bluetooth, iRDA (Infra Red Data Association), WiMax, Zigbee, or the like. Embodiments in which the first network connection between the data storage device and the synchronisation device are wireless can be advantageous as they can provide a user with flexibility as to the location of the data storage device; there is no need to place the data storage device in physical proximity of the synchronisation device. 
     The first data connection may typically be a short range connection since it is likely that the synchronisation device and the data storage device will generally be physically close to one another. Thus, short range is intended to mean a connection between two proximal devices rather than a long range connection such as between devices in different rooms, or even different buildings. Some embodiments may provide long range data connections. 
     The data storage device may be any of the following: a digital camera (whether still, video or combination thereof), a mobile telephone, an MP3/MP4 player, a watch, a games console or any combination of these. The data storage device may also be part of the fixtures and fittings of a building, be inside a domestic appliance, a car or any other device capable of generating and/or storing data but generally, the data storage device will comprise a device which is capable of being held in a user&#39;s hand; ie it is a handheld device. As such, the data storage device is likely to be considered a portable device. 
     The synchronisation device may be connected to a second network which is connected to a Wide Area Network (WAN), such as the Internet. The system may comprise an access device arranged to connect the synchronisation device to a Wide Area Network (WAN). The access device may comprise any suitable device such as a MODEM, a router, or the like. The access device may or may not be provided as part of the synchronisation device. 
     In one embodiment the access device is an ADSL (Asymmetric Digital Subscriber Line) MODEM in conjunction with a wireless router. In such an embodiment, the synchronisation device is arranged to connect to the access device via the wireless router (which provides a second network) which subsequently connects to the Internet via the ADSL MODEM. 
     In an alternative, or perhaps additional embodiment, the access device is a Homeplug MODEM, which may be an ADSL MODEM. In such an embodiment, the synchronisation device is arranged to connect to the access device via the mains wiring of the building in which it is used (which provides a second network) which subsequently connects to the Internet via the MODEM. 
     The synchronisation device may comprise a second data connection arranged to connect the synchronisation device to the second network. The second data connection may be arranged to connect in a wired and/or wireless manner. Indeed, the connection to the second network may be any of the technologies mentioned in relation to the first data connection of the synchronisation device. 
     Additionally, the second data connection may comprise a means to send data over mains wiring. For example, the connection to the second network may be via a HomePlug™ protocol or the like. 
     In some embodiments, the synchronisation device may be provided within the housing of mains plug arranged to be plugged into a mains socket and/or provided with a cable which plugs into a mains socket. 
     The synchronisation device may be arranged to store data from the data storage device upon a file store upon the second network. The file store may be provided by a personal computer such as a PC, Apple™ or the like, a Network Attached Storage (NAS) device or the like. 
     Alternatively, or additionally, the device may be arranged to store data from the storage device upon a file store connected to a WAN connected to the second network, such as a content server. 
     In some embodiments, the synchronisation device may be arranged to store data from the data storage device upon a remote data display device connected to the second network and/or a WAN connected to the second network. The remote data display device may comprise a digital photo frame. As such, embodiments of the system may provide a convenient mechanism which can reduce the amount of user interaction needed to update information on a digital photo frame. In such an embodiment, the display device may be thought of as a content server. 
     The synchronisation device may comprise a local power source. The local power source may be arranged to power the synchronisation device and/or a storage device connected thereto. Provision of a local power source in this manner can advantageously make the synchronisation device portable. 
     The local power source might for example be a battery, a solar cell, a fuel cell, a wind up source, or any other suitable means. 
     The synchronisation device may be arranged to run one or more applications that adapt the upload and/or download of content data to/from a data storage device parameterised by the connection data in the same way. These applications may be arranged to adapt the content data by applying criteria to the transfer of data to and/or from the data storage device. They may also adapt the content data to deliver additional features by combining data from one or more sources. These sources include at least one of the following: one or more data storage devices; one or more synchronisation devices; one or more control servers; and one or more content servers. The applications may also drive or provide other data to other applications installed either on one or more data storage device and/or one of more content servers. 
     The synchronisation device may be arranged to combine content data that is obtained from a plurality of content servers. Such an arrangement may be useful to create newsreels or mashups of intelligently selected content data from multiple sources. The system may for example be arranged to use filters on one or more content servers to download and combine one or more files relating to a certain search phrase like a favourite sports team. This same method of combining files may also be used to place advertising within the content and may use information gathered about the user within the system, or from sources external to the system, to intelligently place such content data. 
     The synchronisation device may be arranged to download program data to the storage device. The program data may be determined by the device identifier and/or device capability such as specified in the capability data. Such program data may be executable by an Operating System (OS) running on the data storage device or may be the, or at least a component of, the OS. Such an arrangement may allow an application to be delivered to a data storage device taking into account the OS of the data storage device. Applications on the storage device may or may not be fully or partially controlled by the synchronisation device and may or may not be parameterised by the connection data (ie have parameters set within an application set by the synchronisation device as controlled by the capability and/or connection data). 
     The synchronisation device may be arranged to adapt the transfer of content data from a data storage device to a content server. Such an arrangement may be beneficial, for example to either limit bandwidth use or to enable service features. For example, the transfer may be started and stopped intelligently by the synchronisation device, generally by an application running thereon. This may be useful for example, if the data storage device is a web cam which is monitored by the synchronisation device. The synchronisation device may be configured to start streaming when movement is detected and/or depending on time of day, or the like. The content server may be configured to store the images, but may also relay them on to security personnel. 
     Some embodiments of the system may be arranged to provide a web conferencing service. In such an embodiment, the content server may be arranged to provide a remote display device with either an embedded and/or separately connected camera and the control server may be arranged to be a signalling platform that controls how the synchronisation device directs content data (ie video and/or audio signal in this embodiment). 
     A combination of one or more applications running on a data storage device and one or more applications running on a synchronisation device may be configured according to the connection data and/or the capability data. These applications working together may for example allow all or parts of a data storage device to be backed up and/or have its contents and settings transferred to a second data storage device and/or content server. Such an embodiment, may prove advantageous as it would allow a user to configure a new data storage device (ie second data storage device) with settings uploaded from an existing data storage device. In one specific example, a user may configure a new mobile telephone with settings from his/her existing mobile telephone, wherein the mobile telephone provides an example of a data storage device. 
     The synchronisation device may be arranged to upload settings from a first data storage device, to map the transfer of settings to a second data storage device and download the mapped settings to a second data storage device. 
     In additional or alternative embodiments, the system may be arranged such that customer service may be provided to users of data storage devices. The system may be deployed to deliver error checking software directly to the data storage device or may be arranged to run such software as an application on the synchronisation device. Such an application may allow a service agent to fix problems either by manual inspection or automatically through the application itself downloading new settings to the data storage device. The system may also use the backup and replacement capability in this scenario to ensure no loss of data. 
     The system may comprise a profile database containing data identifying any of the following, using the device identifier as an identifier to the database (which might be the primary key):
         the user owning the device;
           any other devices owned by the same user;   
           the type of device;
           for example whether it is a phone, camera, MP3 player, Video player, PSP, thumb drive, web camera, etc. where each type has a unique mixture of photo/video/audio/application high level data creation and consumption capabilities. Such information may be used to suggest appropriate content servers; for example photo stores for cameras and phones but not for MP3 players which do not handle image data and also to determine which applications to run on the synchronisation device;   
           a list of one or more data storage device formats the data storage device is capable of utilizing
           for example containing device specific information such as the screen size, supported file formats, operating system and program environment, etc.;   
           a list of one or more content servers to which the data storage device can upload content data,
           the user ID and password of any personalized account on the or each content server, the file format(s) supported by the or each content server,   the or any application or combination thereof to be run on the synchronisation device and/or storage device to communicate with the or each content server,   the number of files to be uploaded and their directory sources on the storage device for the or each content server,   any tags to attach to files or groups during the or each transfer process where such tags may or may not be generated by an application running on the synchronisation device,   data not on the storage device to be combined with data from the storage device by an application on the synchronisation device to create one or more combined files for sending on to the or each content server,   where the content server may be another storage device; and   
           a list of one or more content servers from which the data storage device may download content data.
           the user ID and password of any personalized content feed on the or each content server,   the file format(s) delivered by the or each content server,   the or any application or combination thereof to be run on the synchronisation device and/or storage device to communicate with the or each content server,   the number of files to be downloaded and their directory destinations on the storage device for the or each content server,   any filters to apply to content available on the or each content server,   any tags to attach to files or groups of files during the or each transfer process where such tags may or may not be generated by an application running on the synchronisation device,   data from one or more content servers may be combined by an application on the synchronisation device to create one or more combined files for the or each storage device,   where the content server may be another storage device   
               

     The profile data is generally held by device ID. Each data storage device may be associated with a user who can control the or each data storage device from a control panel which may be accessible remotely. Such a control panel may or may not be provided by a 3 rd  party and may write service updates to the Control Server through a secure application interface. 
     Generally, the profile database is held on the control server. However, in some embodiments, it is conceivable that the profile database is held on the synchronization device. Further in some embodiments, a plurality of databases may provide the profile database. 
     In a likely use of the system components, the content server and the control server are separate components to reduce the duplication of common elements across different content servers and to simplify content server subscription through reduced data entry. The control server may be arranged to hold the element that do not change from one content server to another, for example the device capabilities, and may also be arranged to allow a user to see a device centric view in a control panel to manage multiple content providers easily. 
     Furthermore, it is likely that the synchronisation device will be separate from the control server to enable any storage device to use any synchronisation device to access any content server in any format. 
     According to a second aspect of the invention there is provided a synchronisation device comprising:
         processing circuitry;   a first data connection arranged to have a data storage device connected thereto and in communication with the processing circuitry;   a second data connection arranged to connect the synchronisation device to a network and pass data to and from the network from the processing circuitry;   wherein   the processing circuitry being arranged to:
           1. establish a connection with a data storage device connected to the first data connection;   2. receive connection data from the second data connection and subsequently process said connection data;   
           the processing circuitry being further arranged to process the connection data and perform at least some of the following steps:
           3. download data from a content server at a location specified by the connection data;   4. upload content data received from the content server to a data storage device connected thereto;   5. download content data from the data storage device; and   6. upload content data from received from the data storage device to a location specified by the connection data.   
               

     An advantage of such an arrangement is that the task of synchronising a data storage device is automated not only removing user inconvenience but also removing a user&#39;s computer from the task of synchronisation. As such, the complexity of configuring a computer is removed. The synchronisation device may allow a user to synchronise his/her data storage device regardless of location since the content data (which might be viewed as a user profile) is stored remotely. 
     The device may be arranged to obtain a device identifier from a data storage device connected thereto. Such an arrangement may bring the convenience of allowing a user to connect his/her device to any synchronisation device and still have his/her data process as desired. The device identifier may subsequently be used to obtain connection data for that device which may be used to route data as described therein. 
     The second data connection may provide what would commonly be termed a network connection. 
     Moreover, the data that is present on the data storage device is made more secure and less likely to be lost. As such a user is more likely to synchronise his/her data storage device. Data arranged to be uploaded and/or downloaded may include any of the following: pictures, such as photographs; video, such as MP4, DivX, etc.; MP3 or other sound files; contact details; files containing text, any other data format. 
     The processing circuitry may be arranged to perform each of steps 3 to 6. Alternatively, the processing circuitry may perform only some of the steps. For example, the processing circuitry may only establish one of the first and second data connections; it may be arranged to perform only one of uploading and downloading data to the data storage device. 
     The synchronisation device may be arranged to perform conversion of data uploaded from the data storage device and/or of data downloaded to the data storage device. The skilled person will appreciate that whilst many data storage devices have a wide range of data processing capabilities they may only be able to perform those capabilities upon data held in predetermined file formats. Thus, the synchronisation device may be arranged to convert data from one predetermined format to another predetermined format. For example, the synchronisation device may be arranged to convert a DivX movie to an MP4 movie. Conversion may be thought of as a form of adaptation. 
     The synchronisation device may be arranged to resize or re-sample data. For example, if the data is a picture, a movie, or the like then the synchronisation device may be arranged to alter the frame size such that it is suitable for the data storage device. In alternative or additional embodiments, the synchronisation device may be arranged to re-sample audio files in order to change the bit rate, etc. Resizing and re-sampling may be thought of as a form of adaptation. 
     Such data conversion may be specified in capability data downloaded data and may be specified in terms of the capabilities of the data storage device. Thus, embodiments of the invention may be advantageous in that they solve the problem of data compatibility between different devices. Further, arranging the synchronization device such that it is capable of adapting the content data from a first format to a second format should allow the content data to be obtained from a plurality of different content servers and should negate the need to maintain files (ie content data) in a plurality of different formats. However, the skilled person will appreciate that such adaption of content data is likely to be intensive in the processing that it requires. As such, it may be that processing circuitry that is provided within the synchronisation device is more powerful than the skilled person may otherwise expect. 
     Additional or alternative embodiments of the synchronisation device may be arranged to adapt content data downloaded from the data storage device to be compatible with the content server to which the connection data specifies the connection data should be sent. An example of where such an embodiment may prove useful would be in an arrangement that uploaded, perhaps automatically, data from the data storage device to a Web site such as Facebook, Flickr or the like. Such Web sites have a specific format in which data should be formatted and adaption of the data can facilitate uploading to such web sites. 
     The synchronisation device may be arranged to adapt content uploaded from the data storage device according to capability data. 
     The first data connection may be a wired connection and/or a wireless network connection. Should a wired network connection may be used then it may be arranged to charge the data storage device as it is connected to the synchronisation device. 
     The first data connection may be through a USB (Universal Serial Bus) link. Alternatively, or additionally, the first data connection may be provided by a Firewire connection, a WIFI connection, or the like. The first data connection may be any of the embodiments described in relation to the first aspect of the invention. 
     The second data connection may be achieved through Powerline Communications such as a network which conforms to HomePlug specifications (1.0, AV etc.). Alternatively, or additionally, the second data connection may be a WIFI, Ethernet or any other suitable form of connection. 
     In some further embodiments, the second data connection may be provided via a GSM, UMTS (or other 3G protocol), WIMAX (Worldwide Interoperability for Microwave Access—IEEE 802.16) connection. These protocols provide what may be termed long range connections which may be advantageous in an embodiment in which the synchronisation device is portable. 
     The second data connection may be any of the embodiments described in relation to the first aspect of the invention. 
     The device may comprise a local storage device, such as a hard drive or the like. The skilled person will appreciate that a hard drive may comprise either or both of a revolving platter and a solid state memory such as flash memory. In such a device data uploaded from the storage device may be stored upon the local storage device. 
     Additionally, or alternatively, the device may be arranged to transmit data uploaded from the data storage device across the second data connection to a file storage device. The device may be further arranged to transmit uploaded data across the Internet to a content server. The content server is generally a different server to the control server but this need not be the case. 
     The device may be arranged to send data over the second data connection in addition, or alternatively, to storing the data on the local storage device. 
     In some embodiments, the device may be arranged to transmit data from a data storage device connected thereto to a remote data display device connected via the second data connection and/or a WAN connected via the second data connection. The remote data display device may comprise a digital photo frame. As such, embodiments of the device may provide a convenient mechanism which can reduce the amount of user interaction needed to update information on a digital photo frame. 
     The device may be arranged to transmit account details and/or passwords, etc. in association with data uploaded from a data storage device connected thereto. Such an arrangement is convenient as it allows for a higher degree of security of the data. 
     The device may be provided by a device such as a set top box or the like. Alternatively, or additionally, the device may be provided as a free standing device. 
     The synchronisation device may be arranged to compare files stored on the data storage device with files held at the or each location specified by the connection data and to subsequently move data to and/or from the data storage device in order that the files are substantially the same. The data synchronisation device may however convert some files as discussed hereinbefore such that they are compatible with the data storage device. 
     The data synchronisation device may be arranged to compare dates of files in order to determine which file(s) need to be moved between the data storage device and location specified in the connection data and/or visa versa. 
     According to a third aspect of the invention there is provided a method of synchronising data held on a data storage device comprising the following steps:

     The method may be arranged to upload data from the data storage device. The upload of data from the data storage device may controlled by the connection data received from the control server. 
     The method may comprise receiving, on the control server, an identifier identifying the data storage device and/or data synchronisation device to which the connection data will be sent. Such a method may be advantageous since it allows the connection data to be tailored to the data storage device and/or data synchronisation device. 
     The method may comprise sending the identifier from the data synchronisation device to the control server. 
     Alternatively, or additionally, the synchronisation device may obtain a device identifier from the data storage device. The device identifier may subsequently be sent to the control server. Such a method is convenient as it may allow a user to synchronise his/her data storage device regardless of the synchronisation device to which it is attached. 
     According to a fourth aspect of the invention there is provided a control server comprising:
         a processing circuitry;   a network connection which receives and transmits data between the processing circuitry and a network connected to the network connection;   a data store accessible by the processing circuitry and being arranged to store connection data;   the processing circuitry being arranged to:
           receive data from the network indicative that a synchronisation device is requesting data from the network;   access the data store and retrieve connection data associated with the synchronisation device requesting that data; and   transmit the connection data to the synchronisation device via the network connection.   
               

     The processing circuitry may be arranged to receive one or both of a device identifier and a data synchronisation device identifier. Such a method may allow the server to tailor connection data to the or each device identified by the identifier.

         1. establishing a first data connection between a data storage device and a data synchronisation device;   2. uploading data via the first data connection;   3. transmitting the uploaded data from the synchronisation device via a second data connection to the data synchronisation device to a remote display device; and   4. displaying the uploaded data on the display device.       

     Conveniently, the display device comprises a digital photo frame or the like. 
     Such a method is convenient as it may allow a user to send data (such as picture images) from a camera to a friend and/or member of his/her family that is distant. 
     The method may be arranged to acquire a device identifier associated with the data storage device across the first data connection. 
     The method may send the device identifier to the control server. Subsequently, the control server may be arranged to transmit connection data to the data synchronisation device dependent upon the device identifier. Such a method may allow the data synchronisation device to receive connection data specifying how data held on the data storage device should be handled. 
     Alternatively or additionally embodiments, may transmit a synchronisation device identifier to the control server. 
     Some embodiments may not transmit an identifier to the control server. Such embodiments may have connection data programmed into the synchronisation device. For example, a user may be able to log into the synchronisation device and program the device with the connection data. 
     The method may upload data from the data storage device to a content server. Such storage on the data storage device may enhance data security within such embodiments since a copy of the data is held on the content server. 
     The method may comprise connecting the data synchronisation device to a display device. This may occur after the data synchronisation device has been disconnected from the data storage device. In some embodiments, the display device may be in a location remote from the data storage device.

     The control server may be arranged to download connection data to the data synchronisation device including a pointer to the location of data uploaded from the data storage device to the content server. 
     Subsequently, the method may cause the display device to upload the data from the location. 
     The method may associate the identity of the data storage device with that of the display device. Such a method may allow subsequent invocations thereof to upload data from the data storage device to the display device without the need to connect the data synchronisation device to the display device.

     The association may be held on one or more of the data synchronisation device, the data storage device, the content server or the control server. 
     Alternatively, or additionally, it may not be necessary to connect the data synchronisation device to the display device. For example, in such embodiments, it might be possible to program an association between the data storage device and the display device. For example, a user may be able to specify a network address for the display device. A user may also be able to specify login information such a user ID and/or password. The user id may be the device identifier from the data storage device.

     DETAILED DESCRIPTION OF THE INVENTION 
     The system  100  shown in  FIG. 1  comprises a synchronisation device  102  which has connected thereto a portable storage device  104 . The synchronisation device  102  is also connected to the Internet  106  as are a control server  108  and a content server  109 . 
     In the embodiment being described, the portable storage device  104  is a mobile telephone but other devices are equally possible. For convenience, reference will simply be made to telephone  104  hereinafter. The telephone  104  is connected to the synchronisation device  102  via a USB (Universal Serial Bus) connection which provides both a data connection and a power connection which is utilised to charge the telephone  104 . This USB connection may be thought of as a first data  105  connection to the synchronisation device. Other embodiments may use other connections between the telephone  104  and the synchronisation device  102 . Some embodiments may use both a wired and a wireless connection. 
     The telephone  104  comprises a device identifier, which allows that device to be identified and may be read by the synchronisation device  102  via the USB cable or other connection between them. For example, the identifier may be a Media Access Control (MAC) address, a cookie, a hardware and/or firmware and/or software definable value. In some embodiments, the device identifier may comprise a file that is written to the telephone by the synchronisation device  102 . 
     The synchronisation device  102  is connected to and powered from a mains electricity supply outlet  110 . The device  102  comprises a power line adapter which creates a network using the mains wiring of building. In some embodiments the synchronisation device  102  and may be provided within a plug which is plugged into the electricity supply outlet  110 . 
     Another electricity supply outlet  112  of the mains wiring is connected via power line adapter to a MODEM  114  (in this case a Broadband ADSL MODEM incorporating a router, a DHCP server, etc.) which connects to the Internet  106 . Thus, the synchronisation device  102  can connect to the Internet  106  via the MODEM  114 , the two power line adapters and the network provided along the mains wiring of the building. This connection to the Internet  106  (via the mains wiring and the MODEM  114  may be thought of as a second data connection  116  to the synchronisation device  102 ). 
     The components of the synchronisation device  102  are shown in more detail in  FIG. 2 . 
     Within the synchronisation device  102  there is provided processing circuitry including a processor  200 , a bus  204 , volatile memory  206  and a non-volatile memory  208  in which various drivers are stored as described below. The device  102  also comprises driver electronics  210  to provide the first data connection (eg the USB connection) which is connected to the bus  204  and also to a connector  212  allowing a USB cable to be connected thereto. The device  102  also comprises driver electronics  214  to provide the second data connection (eg the Powerline Adapter) which is connected to the bus  204  and also to a connector  216  allowing a mains cable to be connected to the device. 
     The non-volatile memory  206  contains various driver and service application modules which are accessed and executed by the processor  200  according to an application program  218  to provide the functionality of the device  102 . 
     A Powerline network adapter module  220  provides the protocol to drive the driver electronics  214 . 
     A USB hub  222  module and a USB Host controller module  224  provides the protocol to drive the drive electronics  210  to allow a USB device to communicate with the processor  200 . Data storage devices, such as the telephone  104  are implemented in various ways to enable communication and data transfer from/to a host system. Thus, the USB host controller module  224  enables mobile data storage devices that are implemented according to USB mass storage class specification to be used with the synchronisation device  102 . A disk driver  226  implements ATA (Advanced Technology Attachment) and/or SCSI (Small Computer System Interface) commands allows the processor  200  to access the telephone  204  as a removable disk drive. A file system driver module  228  implements FAT12/16/32 file formats and lets the application  218  instruct the processor  200  to access data held on the telephone  104  which is organised in files and folders. 
     A MTP (Media Transfer Protocol) module  230  provides compatibility with telephones  104  which implement the MTP protocol over USB. 
     An RNDIS (Remote Network Driver Interface Specification)  232  module is provided to allow telephones  104  which implement Microsoft™ ActiveSync™ or OMA (Outlook Mobile Access) to be accessed by the processor  200 . 
     An NDIS (Network Driver Interface Specification) module  234  allows data to be transmitted over the Powerline Network Adapter  220 . 
     A TCP/IP (Transmission Control Protocol/Internet Protocol) module  236  provides access to both the RNDIS  232  and NDIS  234  modules. 
     A DHCP (Dynamic Host Configuration Protocol) client module  238  allows the synchronisation device to obtain a network address from a network connected via the second data connection  116  when in it is connected thereto. 
     An HTTP (Hypertext Transfer Protocol) server  240  allows remote access of the synchronisation device  102  via the second data connection  116  which can for example allow for remote configuration of the device  102  through the CGI (Common Gateway Interface) module  242 . Thus for example, if it were desired to use a fixed network address for the device rather than an address obtained by the DHCP module  238  it is possible to remotely log onto the HTTP server  240  and make this configuration. Other configurations may be equally possible. 
     In use and as described in relation to  FIG. 6 , a user plugs the synchronisation device  102  into the mains wiring of a building (step  600 ). The DHCP module  238  communicates with a DHCP server within the network to which the Powerline Network Adapter  220  connects, such as within the MODEM  114  and obtains a network address for that network (step  602 ). As such, the synchronisation device  102  is acting as an IP addressable Internet endpoint and can be seen over the Internet by devices having its network address. 
     A user can then connect a telephone  104  to the synchronisation device  120  using a USB cable (step  604 ). Not only does the USB cable commence charging the telephone  104  but the USB hub and controller  222 ,  224  allow the processor  200  to communicate with the telephone  104  once a connection thereto has been established. 
     The synchronisation device  120  reads the device identifier from the telephone connected thereto  104 . 
     Once a network address has been obtained by the DHCP module  238  the processor can communicate via the second data connection  116 , via the Internet  106  to the control server  108  (step  606 ). Once this communication is established, the synchronisation device  102  is arranged to transmit a synchronisation device identifier (which is generally a unique identifier) to the control server  108  which identifies that synchronisation device  102  to the control server  108  (step  608 ). 
     In some embodiments, the synchronisation device  102  also transmits the device identifier across the second data connection  116  to the control server  608 . In some embodiments, the synchronisation device may not transmit the synchronisation device identifier. 
     The control server is arranged to access a data store (such as a disk array) to which it has access and retrieves connection data and capability associated with either or both of the synchronisation device and/or device identifier. The capability data includes the capabilities of the telephone (ie the data storage device) to which the synchronisation device is connected and the connection data provides a list of content servers to and from which data should be respectively uploaded and downloaded. 
     In order to generate the connection and capability data, the control server comprises one or more databases which hold data for each device identifier. This may be thought of as a user profile since the device identifier will generally be specific to a single person unless that person shares the telephone. In the embodiment being described, the data held for each identifier includes: a list of web sites from which data should be downloaded to the telephone; a list of web sites to which data should be uploaded from the telephone; and the capabilities of the telephone. 
     This connection and capability data are then transmitted via the Internet  106  and the second data connection  116  to the synchronisation device and stored within the memory  206  (step  610 ). In some embodiments, the synchronisation device is arranged such that the connection and capability data are lost when power is removed from the device; ie the connection data is stored in a volatile memory thereof. 
     The connection data provides a reference (such as an IP address) to one or more content servers  109  from which a user of the telephone  104  which to obtain content. The synchronisation device  102  is arranged to access the connection data and subsequently connect to each of the content servers  109  specified therein and synchronise data held on the telephone  104  with the or each content server  109  (step  612 ). Thus, the control server  108  is storing a profile used to control what data is synchronised with the telephone  104  and it should be noted that content data is downloaded from a location which is generally different from the control server  108 . 
     For example, the content server  109  may have thereon a daily podcast to which the user of the telephone  104  wishes to listen. In such an example the synchronisation of the telephone  104  includes a determination as to whether the telephone has stored thereon the latest version of the podcast. If the latest version is not present then the synchronisation device  102  downloads the latest version of the podcast from the content server  109  and uploads the podcast to the telephone  104 . 
     Because the capability data holds information as to the capabilities of the device, the synchronisation device monitors the format of content data from the or each content server. If the synchronisation device determines that the format of the content data is not suitable for the telephone then the synchronisation device adapts the content data, from this first format, to a further format that the telephone is capable of processing and the adaption is performed as specified within the capability data. This further format may be thought of as a data storage device format. In the case of an audio file for example, the adaptation may be between MP3 and AAC format. As a further example, in the case of video the adaptation may include altering the screen resolution. As yet a further example, in the case of a document file, the adaptation may include converting a WORD™ file to a Rich Text file. 
     The synchronisation may also ensure that any media created by the storage device is synchronised with a remote source, which may be a content server  109  or a storage device on a network to which the second data connection  116  connects. This will help to ensure that no data such as photographs, videos, notes including audio and written or typed, contact information, etc. are lost if the telephone  104  is lost or damaged (step  614 ). 
     In some embodiments, the synchronisation device  102  may be arranged to store data received from the second data connection within a predetermined location (such as a folder) within the telephone  104 . Such embodiments, may allow the synchronisation device  102  to store data received from the second data connection on the telephone  104  regardless of the identity of the telephone; ie a user may plug any telephone  104  into the synchronisation device and have data saved onto it from the synchronisation device  102 . 
     Further, some embodiments of the synchronisation device  102  may be arranged to upload data from a predetermined location (such as a folder) when a telephone  104  is connected to the synchronisation device  102 . For example, in embodiments, in which a camera is connected to the synchronisation device  102  the device  102  may be arranged to upload files in the folder DCIM, which may therefore be thought of as a predetermined location. 
     Some embodiments may be arranged to upload only files that have been added to the predetermined location since the last time that the telephone  104  was connected to the synchronisation device  102  since this should reduce the amount of data that needs to be transmitted. 
     In one convenient method, a user connects his/her telephone  104  to the synchronisation device  102  during an evening. The telephone  104  is then left, for example overnight, and during this time the telephone is charged and also synchronised. Synchronisation may be thought of as uploading data from the telephone and downloading data to the telephone. 
     Some embodiments of the synchronisation device  102  may be arranged to download data from the or each content server  109  from time to time, which may be periodic. For example, in one embodiment, the synchronisation device  102  is arranged to download data from the or each content server  109  at a predetermined time each day and store the downloaded data within the memory  206 ; ie the synchronisation device is buffering that data. When a telephone  104  is subsequently connected to the synchronisation device  102  the buffered data may be downloaded to the telephone. An advantage of such a method is that it may be more convenient for a user since data may be transferred to the telephone more quickly than having to wait for it to be transmitted across the second data connection. 
     Alternatively, or additionally, some embodiments may be arranged to upload data from a telephone  104  connected to the synchronisation device  102  and to buffer that data until a second data connection becomes available. Such an embodiment may be particularly convenient for embodiments of the synchronisation device that are arranged to be portable and which do not always have a second data connection thereto. 
       FIG. 3  shows a further embodiment of a system implementing the invention and like parts are referred to with the same reference number. In addition to the system described in  FIG. 1  the system comprises a personal computer  300 , such as a PC, an Apple™ or the like which is in communication with a network to which the second data connection  116  establishes a connection. In particular the computer  300  is connected to the MODEM  114 . 
     In some embodiments it is possible for a user of the personal computer  300  to log onto the HTTP server  240  on the synchronisation device  102  in order to the configure the device  102 . In such embodiments, the user may or may not be able to amend the connection data. 
     A user of the computer  300  is able to log onto the control server  108  and amend the connection data which is held (or is at least accessible by) the control server  108 . Thus, a user is able to configure the data that will be downloaded to his/her data storage device upon connection to the synchronisation device  102 . For example, a user would be able to edit the data held in the or each database that provides his/her user profile. 
     It will be appreciated the computer need not be directly connected to a network to which the second data connection  116  is connected in order to access either the control server  108  or the synchronisation device  102 . However it will be generally convenient if access to the synchronisation device is by computers  300  (or other devices) which are on a network to which the second data connection  116  connects. 
       FIG. 4  shows a further embodiment in which the same parts are referenced with the same reference numbers. In this Figure details of the second data connection between the synchronisation device  102  and the Internet  106  are omitted for clarity. 
     In this embodiment three synchronisation devices  102   a  to  102   c  are shown. This could be in the same building or they could be physically remote from one another. However, each allows a data storage device to connect to the Internet  106  and access both the content server  109  or the control server  108 . 
     It will be seen that the synchronisation device  102   b  has connected thereto two storage devices—a telephone  104  and a camera  404 . The synchronisation device may be connected to any number of storage devices such as 1, 2, 3, 4, 5, 6, 10 or more. It will be appreciated that the USB specification allows up to 128 devices to be connected to one another. 
     In such an embodiment in which the synchronisation device connects to more than one device the reading of a device identifier from the device may allow the synchronisation device to tailor synchronisation that is performed with each device to that device; ie the synchronisation device may have a profile specific to each device connected thereto. The skilled person will appreciate that synchronisation performed for one data storage device  404  may be different compared to synchronisation that would be performed for a second data storage  104 . 
     The synchronisation device  102   a  has an MP3 player  400  connected thereto. 
       FIG. 5  shows a further embodiment in which the same parts are referenced with the same reference numbers. In this Figure details of the second data connection between the synchronisation device  102  and the Internet  106  are omitted for clarity. 
     In this embodiment, the synchronisation device  102   b  is arranged to upload image data from a data storage device (in this embodiment a camera)  404  to a remote display device  500  which in this embodiment is a digital photo frame. The photo frame  500  is connected to the Internet  106  and has an IP address allowing data to be sent thereto. 
     The skilled person will appreciate that the photo frame may be connected to a network and which that network connects to the Internet in the same way as described herein in relation to how the synchronisation device connects to the Internet  106 . 
     In the embodiment being described, the synchronisation device  102   b  can be used to establish communication between the data storage device  104  and the display device  500  by using the method as described below. 
     Initially, a user connects the synchronisation device  102   b  to the data storage device  104  which uploads a device identifier from the telephone  104 . This identifier is then sent to the control server  108  which is arranged to send connection data relating to the telephone  102  back to the synchronisation device  102   b.    
     The connection data received from the control server  108  includes a location on a content server  109  to which data uploaded from the telephone  104  should be sent. Thus, the synchronisation device  102   b  subsequently uploads data from the telephone  104  to the content server  109 . 
     The user may then disconnect his/her telephone  104  from the synchronisation device  102   b  and at a later time connect this to a display device  500  such as a photo frame. Again, the synchronisation device is arranged to upload a device identifier from the display device  500  and send this to the control server  108 . 
     The control server sends connection data to the synchronisation device  102   b  including a pointer to the location at which data is stored from the telephone  104 . The synchronisation device may then cause the data stored on the content server  109  to be uploaded to the display device  500 . 
     In subsequent invocations of the method it may not be necessary to connect the synchronisation device  102   b  to the display device  500  since a link may have been established within the memory of the synchronisation device in order that data uploaded from the telephone  104  may be considered for upload to the display device  500 . For example, a user may be able to specify which data is uploaded to the display device  500 . 
     The synchronisation device is arranged to send a USERID and password which have been programmed thereinto to the photo frame in order to gain access. The skilled person will appreciate that a user could also enter the USERID and password rather than having them stored on the synchronisation device. 
     Once communication has been established between the synchronisation device and the photo frame the synchronisation device uploads images from the camera  404  to the photo frame. The images may be buffered on a storage medium (such as a hard drive) within the synchronisation device or they may be uploaded directly from the camera. 
     In some embodiments, the synchronisation device comprises a screen, such as an LCD screen, on which a user may view images from the camera and determine which images are to be uploaded to the photo frame. Such embodiments, may also comprise a user input, such as a joystick, a number of buttons, or the like which allow a user to input to the synchronisation device which images should be uploaded. 
       FIG. 7  shows a further embodiment of a system implementing the invention and like parts are referred to with the same reference number. In this embodiment, the synchronisation device  102  is arranged to be portable and as such comprises a local power source  700  which in this embodiment is a battery. In this embodiment, the capacity of the power source  700  is high enough such that the first data connection  105  can be used to re-charge the telephone  104 . 
     The synchronisation device  102  also comprises a 3G MODEM which allows the device to establish a data connection to the Internet  106 . Thus, in such an embodiment the second data connection may be provided by the data connection established using the 3G MODEM. 
     Other embodiments of the invention may use a MODEM within the data storage device  104  to establish the second data connection  116 . Such an arrangement would simplify the circuitry required within the synchronisation device  102 . 
     Yet further embodiments, may allow the synchronisation device  102  to connect to a further device (such a laptop, further telephone, etc) and utilise a data connection between that further device and the Internet  106  as the second data connection  116 . 
       FIG. 8  shows a further embodiment of a system according to the invention and like parts are referred to by like reference numbers. However, in this embodiment the synchronisation device has been replace by a synchronisation module  800  provided on the storage device  104 . 
     It will also be seen that it this embodiment, the storage device  104  connects to the MODEM  114  using a WIFI connection  802 , which provides the second data connection  116 . Yet further embodiments, could utilise a second data connection as described in relation to other Figures. Still yet further embodiments, may replace the power line adapter technology described in relation to earlier Figures with a WIFI link as shown in  FIG. 8 . 
     The skilled person will appreciate that in the embodiment of  FIG. 8 , the first data connection  105 , described in relation to other Figures, is provided within the storage device  104  between the synchronisation module  800  and the other processing circuitry of the storage device  104 . 
     An embodiment such as shown in  FIG. 8  may be advantageous so as to provide the synchronisation device on the same physical hardware as the storage device. As such, the synchronisation device may then be thought of as a synchronisation module. Such a synchronisation module may be provided as an application running on the storage device which contacts a control server to retrieve connection and capability data that is used by the synchronisation device application to upload, download and adapt the user&#39;s data to and from the storage device. However, the skilled person will appreciate that the synchronisation module could equally be provided by firmware, hardware or a combination of software, firmware and/or hardware. As such, in such an embodiment, the synchronisation module may provide the same or at least substantially the same functionality as the synchronisation device described elsewhere. 
     In such an embodiment, the synchronisation module may be automatically triggered by the storage device being connected to a power supply.
