The present invention relates to routing of data including multimedia between electronic devices, and more particularly but not exclusively to rerouting of incoming communications that may or may not include multimedia to devices other than the initial receiving device. Data may arrive from external sources via communication or generated by, or at, a device. Data may be a package or a stream. Such a stream may be unidirectional, bi-directional or multidirectional.
With the introduction of mobile communication devices, telecommunications technology has transformed society over the past decade. The ability to communicate almost anywhere, anytime, with few geographical limitations has resulted in a society, in both social and business contexts, which is almost always on-line. Mobile communication devices today typically have data processing ability which allows them to handle multi-media, and different types of devices are today able to communicate with each other, either directly via a permanent or temporary link or indirectly via a network. Thus data, including multimedia, can be directed or routed from one device to another device. The idea of multi-media routing stems from the myriad of opportunities which present themselves in routing signals from one device or kind of device to another. However, in general, the playing of multimedia data is limited, at least in the short term, to the device on which it is received, or to those in which the data originates. This limitation can be a considerable limitation on the user's ability to enjoy the multimedia since different devices have very different capabilities regarding the playing of multimedia.
The media playing devices considered specifically in the present disclosure include both mobile devices (cell phones, PDA's, handheld devices, etc.) and non-mobile devices (land/fixed line phones, computer monitors, Hi-Fi sets, speakers, etc.). Some of the devices may be used for just one or two media types and others are more general in their applicability, which is to say it is possible to use the devices in different modes for playing several media types: voice, text, images, and video. Likewise, the devices are used in various locations: at the office, home, car, hotel room, plane, outdoors, etc.
Most current mobile devices in particular provide relatively poor multi-media capabilities including digital audio, image, and/or video capabilities (as well as other media capabilities) in comparison with other existing devices such as land/fixed line phones, computer monitors, TV screens and Hi-Fi sets. Compared to high quality media playing equipment, even 3rd generation mobile devices (3G) are of inferior quality.
A number of patent applications discuss rerouting of communications from one communication unit to another. An example is GB 2,370,451, which discloses a communication unit that detects the presence in its vicinity of a second communication unit and determines its identity. If the identity is found to be of a predetermined set (e.g. of communication units having the same owner) calls made to the second communication unit are diverted to the first unit. The arrangement is useful where a user has multiple communication units, for example a car telephone and a cellular handset, with differing telephone numbers as the user may be contacted using any of these.
WO0141317A3: call diversion system, discloses a system specifically for redirecting calls between satellite and terrestrial cellular systems. The disclosure addresses the issue of reformatting data messages for the transition.
Neither of the above systems takes into consideration the types of multimedia content of the incoming calls data or playing quality and usage comfort when deciding whether to redirect, and redirection is based on devices having a shared ownership or otherwise being part of a predetermined set. In the above-described systems the user typically has only limited control over rerouting. Nevertheless, it would be highly advantageous to provide the user with the ability to select a target device, based on the type of multimedia content, and furthermore to choose a device for play or storage of the content independently of the initially targeted or originating device.
According to a first aspect of the present invention there is thus provided data rerouting apparatus for association with electronic equipment for rerouting data, comprising:
an announcer device for indicating to surrounding equipment that said associated equipment is available for rerouting, thereby to enable receipt of rerouted data therefrom, and a scout device for scanning surroundings of said associated equipment to find out about compatible equipment in the vicinity, thereby to reroute data thereto.
The apparatus preferably further comprises a user interface associated with said scout device for allowing a user to select between available compatible equipment to reroute data thereto.
Preferably, said scout device is operable to determine media type requirements of said compatible equipment, the apparatus further comprising a media transformer, associated with said scout device, for transforming media into a form that accords with said determined media type requirements.
Preferably, a plurality of types correspond to said media type requirements, and further comprising a user interface for allowing a user to select one of said media type requirements for transforming at said media transformer.
The apparatus preferably further comprises a media cloner for making multiple copies of the data, in particular but not exclusively an incoming communication, thereby to enable said apparatus to redirect, for example, a single incoming communication to a plurality of locations.
Preferably, said announcer is an active device, operable to transmit at least status information to respective surroundings.
Preferably, said announcer comprises a passive device, carrying at least device identification information for reading by an active scout device.
Preferably, said passive device further carries status information of said device.
Preferably, said announcer comprises a barcode and wherein said scout is a barcode reader.
The apparatus preferably further comprises an outgoing multimedia transmitter for directing rerouted media directly to a selected device.
The apparatus preferably further comprises control functionality operable to inform a communication service provider of a desired rerouting, thereby to enable said communication service provider to reroute said data.
The apparatus preferably comprises control functionality operable to carry out said rerouting directly.
The apparatus preferably comprises control functionality operable to carry out said rerouting through locally available network infrastructure.
The apparatus preferably comprises a device database for storing compatibility data of different equipment types.
According to a second aspect of the present invention there is provided a method of rerouting data comprising:
Receiving or generating said data at a first device,
determining availability of other devices in the vicinity of said first device, and
rerouting said data to at least one target device selected from devices found to be available.
The method preferably comprises determining compatibility of said available devices in said vicinity with said communication.
The method preferably further comprises carrying out media type transformation from a media type of said data to a media type compatible with a selected device.
The method preferably further comprises carrying out selection between devices found to be available, via a user interface.
The method preferably further comprises carrying out a selection between devices found to be available, based on a predetermined user profile.
The method preferably further comprises selecting a plurality of devices to reroute said data thereto, and cloning said data for each selected device.
The method preferably further comprises determining availability of other devices in the vicinity of said target device, and
rerouting said data to at least one further target device selected from devices found to be available.
According to a third aspect of the present invention there is provided a data rerouting apparatus for association with electronic equipment for rerouting data to at least one selected target device, comprising:
a cloner for making multiple copies of incoming data, thereby to enable said apparatus to redirect single incoming data to a plurality of respective target devices, and
a transformer, associated with said cloner, for receiving at least one of said multiple copies of said incoming data, and transforming said data into a form that accords with a determined media type requirement of a respective target device.
For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, purely by way of example, to the accompanying drawings.
With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiments of the present invention only, and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention may be embodied in practice. In the accompanying drawings:
The capability of routing of multi-media content (possibly including media transformation and multiplication, i.e. cloning) from one device to another may dramatically upgrade media playing quality, and grant the user the liberty to play the content on any device he wishes, preferably the most suitable device available, regardless of the origin of the content or the device to which the content may initially have been directed, or at which the content originates. Furthermore, by rerouting to a more capable device, a user's satisfaction level may be increased in comparison to having to remain with a device that say is limited by inferior data rate, processing power, memory capacity or input/output facilities. For example, a cellular communication device such as a mobile telephone is such a limited capability device which is typically the initial recipient of a communication. Such an initial recipient, or originator, is referred to hereinafter as the routing-source device. Furthermore, as will be explained below, the ability to route content from non-mobile, that is land or fixed devices to nearby mobile and other devices permits a range of possibilities for use which is currently not provided for.
For example, the ability to route an incoming phone call, typically comprising voice, from a mobile device to a land/fixed line phone may generally be expected to upgrade the quality of the call. The ability to route hand held calendar content from a mobile device having some digital ability to a computer monitor, may allow for better viewing of the information. Such rerouting may also enhance the user's ability to share the information with other people or with computer applications, for example applications that capture information displayed on the monitor and use it to trigger other events. Such applications can easily be run on a PC or laptop computer but are difficult to run on a mobile telephone for example.
An incoming call or other originating data may be rerouted more than once. In preferred embodiments, individual devices do not need to know whether they are an initial receiving device or a first or subsequent rerouting device, and may treat any arriving communication in the same way.
Furthermore, a preferred embodiment of the present invention provides an ability to route an incoming voice message from say a mobile device or voice mailbox to a facsimile machine or display monitor, combined with a transformation capability —in this case an ability to transform voice to text. Software packages that interpret voice and translate into text are well known and commercially available. Such packages, which presently require training on a specific voice in order to produce reasonable results, may broaden the usage of voice messages. However, even without training, the best packages can produce sufficiently good results to enable say the hard of hearing to make a reasonable interpretation of an incoming voice signal. Thus such a rerouting-while-transforming capability may be highly desirable for people with special needs—impaired senses (hearing, vision) who may use such a capability to receive information in a form more usable to them. Likewise such a capability may be useful for receiving communications in difficult environments such as a noisy factory floor.
As a further example, an incoming phone call directed at a land/fixed line may be rerouted to a mobile device, thus, effectively using the mobile as a cordless phone. Such a technique may ease acceptance of a phone call in a hotel lobby, at a colleague's office, at a restaurant and in many other settings.
Routing an incoming call away from a mobile telephone may also be advantageous health-wise in decreasing the physical proximity of electromagnetic radiation (emitted by mobile devices) to the user.
It is pointed out that communication-enabled devices can receive an incoming communication for rerouting. However as long as rerouting is direct from device to device, the device to which the rerouting is made need not be generally enabled for external communication as typically managed by a service provider be it phone, cellular, internet and the like. Furthermore, routing is not limited to rerouting of incoming communications but also applies to routing of data from any kind of data source to any kind of data player. Data may arrive from external sources via communication or generated by, or at, a device. Data may be a package or a stream. Such a stream may be unidirectional, bi-directional or multidirectional. Thus video data being captured at a video camera may be directed using embodiments of the present invention to a convenient nearby video player or multimedia enabled PC. Thus, a generally non-communication enabled device will be unable to receive initial communications but can route data to other devices and can receive data as a rerouting target.
Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is applicable to other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.
Reference is now made to
It is noted that in the case of a cellular telephone, the telephone communication is a bi-directional type of communication, and any rerouting should preferably support a return path for the communication.
In addition, using the above rerouting, a call can be set up to support a game session. The call can be set up using a cellular telephone, and then one or both users reroutes the call to a game console.
The above may be achieved by sending rerouting control data along with the rerouted communication, which control data includes a return address. The return address may be a final return address for single stage rerouting, or may be an intermediated return address in the case of multi-stage rerouting. In the latter case, the intermediate return address can be used in an intermediate rerouting device to find a further rerouting address.
Reference is now made to
The device comprises an incoming multi-media receiver 20 which is responsible for capturing media content and passing it to one of the other components in the device, depending on the circumstances, as will be explained below. One of these other components is outgoing multi-channel multi-media transmitter 22. Transmitter 22 is responsible for transmitting (directly) media streams to external devices which are specified to it. Transmitter 22 comprises a multi-channel port which is able to transmit several media types to several devices at the same time.
A media transformer 24 is responsible for transforming its input (incoming media) into a required media type, or types, and outputting the resulting media stream(s), or file(s). It too preferably has a multi-channel Output. The media types required as output are preferably specified externally. A preferred embodiment of a media transformer includes a voice to text transformer as discussed above. The voice to text transformer may be augmented by a text to fax transformer. Further transformations include image transformations such as color to black and white, resolution reductions, and image format transformations. Similar transformations may be provided for video, and to the extent applicable for sound formats.
Media cloner 26 is responsible for duplication of its input channel content, preferably received from the incoming multi-media receiver 20 (input media) into as many output channels as indicated to it externally. Each output stream, or file, is routed, as indicated to it externally, to either the media transformer 24 or the outgoing multi-media transmitter 22.
Controller 28 is responsible for managing all the other components and monitoring their activities. In particular, any media (packaged or streamed) transfer between components, input and output, is performed under the controller's supervision.
In operation, content is received at incoming multimedia receiver 20. As will be explained in detail below, one or more destinations for the data as well as media type transformations are selected. In the case of straightforward rerouting of the media to another device, the content is sent directly to outgoing multi-media transmitter 22 for simple media routing to a similar content type device. In other circumstances, transforming from one media to another may be required prior to rerouting. In such a case, content is directed to media transformer 24 prior to rerouting, where transforming is carried out. The transformed content is then directed to the outgoing multi-media transmitter 22 as before. Content is directed to media cloner 26 in cases where it is intended to route the content to more than one device, or if for any reason it is intended to send multiple copies to the same device. From the media cloner the content may then be sent directly to the outgoing multi-media transmitter 22 for direct output, or one or more of the copies may be sent to the media transformer for transformation prior to output. Routing of the content and operation of the above-mentioned components is preferably controlled by controller 28.
In order to make decisions about selecting destinations and media types and in order to allow other devices to receive availability information, three more components are preferably provided, an announcer device 30, a scout device 32 and a device library 34.
The announcer device 30 is responsible for announcing to the environment the availability of a current device for accepting routed media. It may also indicate device type and use conditions, preferably including any usage charges, thus enabling surrounding devices to avoid say sending video data to a fax machine, or enabling security conscious users to avoid receiving non-trusted data at their device. When the device becomes busy (for example, a phone that is handling a call), it announces this to the environment, typically via transmissions. Similarly, it announces its becoming available. Announcements may be periodically repeated. As an alternative the announcer device 30 may signal only when available or only when unavailable. Another (optional) function of the announcer 30 is that of informing the environment, typically a user, that media content has been routed to it and is now usable (for example, to announce that a rerouted call is now available on this telephone). The latter kind of announcement, that is to say to persons rather than to electronic equipment, may typically comprise light flashes, rings, a loudspeaker sound or even a smell.
Typically, the announcer device 30 may be active (transmitting) or passive (reacting, or reflecting). A simple example of a passive announcer device is a sticker attached to a phone and supplying say device type and conditions of use information using a barcode. The sticker may be scanned and comprehended by the scout devices 32. In addition to a sticker, a passive announcer may be provided using an LCD screen displaying a barcode. The LCD or like screen is advantageous in that, since its display can change, the barcode can indicate current status information. An alternative way of providing status information along with a barcode is by providing a color display alongside the barcode. The color display may be changed electronically or mechanically by the device to indicate different states, and can be read optically along with the barcode.
The scout device 32 is responsible for scanning the environment to find other devices therein and to determine their status, typically free or busy. The scout is also responsible for obtaining any specific use conditions from announcers 30 of the devices being detected. The scout may be activated periodically and/or upon demand.
Device library 34 contains information needed for communicating with various devices. Such information may typically include usage related information as well as technical information regarding expected media formats and transmission technology specifications, including protocols, used by the device type. It may also contains pre-defined user preferences if defined, including default user preferences.
The controller 28 is responsible for integrating knowledge accumulated by the scout, and for directing operation of the announcer 30. The controller uses either pre-defined user preferences from the device library 34 or it may obtain preferences over a network, or it may simply capture user preferences using menus or like user interaction. The controller preferably follows the appropriate receiving/transmitting protocol including hand shake, identification, authentication, encryption procedures and the like.
The apparatus described in respect of
For example, a host cellular telephone may use already installed IR for scouting and announcing or any of the previously described technologies. A PC may use an existing peripheral digital camera for scouting and local network devices for transmission.
In many situations, as briefly described in previous examples, certain apparatus activities may be initiated via user interaction, and preferred ways of enabling user interaction comprise displaying menus, or using voice menus, or conceivably even using feel or smell menus. Certain actions are preferably taken automatically, that is to say without user interaction. Such automation may be based on profiles, terms, and conditions. Conditions may for example be associated with the device that performs the routing, as well as with a device to which media is routed. Profiles may be stored with the modification apparatus of
Menus may be activated in the following modes:
a) Automatic pop-up menu upon event (incoming call, message etc.)
b) Manual (menu) activation (“always on”.)
To protect against hostile or non-trusted parties, the modification preferably provides some level of firewall protection for both receiving and transmitting components. Such protection may comprise identification and/or authentication, and may comprise restrictions on routing or receiving information to devices whose owners are not trusted. In addition, to protect privacy, transmitted information may be encrypted.
Considering the outgoing multi-media transmitter 22 in greater detail, the transmitter may incorporate one or more of the following transmission technologies for transmitting media to a nearby device:
and other technologies that will occur to the skilled person. The choice of technology may depend on general and specific circumstances, such as the type of data to be transmitted, the environment of the transmission, safety and like considerations, and compatibility with as many as possible other devices.
As described above, rerouting may be direct, that is device to device. Direct (local) routing between devices uses one or more of the technologies specified above but does not usually use any external service provider services, network, or infrastructure. Such routing may however use a local computer network, for example cable or radio-based, or simple end-to-end communication (for example, IR communication between two or more devices).
In addition, rerouting may be indirect. Indirect non-local routing relies on external service provider services, network and infrastructure. Indirect routing still requires the device initially receiving the communication to detect available receiving devices and determine their capability and availability and also requires potential rerouting recipients to announce their capabilities to the environment. The device initially receiving the communication then makes a decision, typically with the help of user interaction, to determine whether to reroute the message and if so to what device, just as before. However the rerouting information is then sent to the external provider who carries out the rerouting of the communication by switching at the exchange. Such a switching method can take advantage of higher data rates over land lines as opposed to wireless connections.
A third rerouting mode uses local network infrastructure to carry out the rerouting. The communication is routed through a local area network (LAN), or a wide area network (WAN) infrastructure with information to indicate to the network which device has been selected for rerouting. However the network has to interpret the information to decide how to route the information. Either kind of rerouting through the available network infrastructure may be useful, for example for rerouting of an incoming phone call from a cellular telephone to a colleague in another room within the same organization.
There are many ways to exploit the capability to route different content (media) types between different devices. Using only rerouting, one may route one form of content (for example audio) only to devices that handle audio (for example, routing an audio stream to nearby speakers). Using rerouting combined with a media type transformation capability, one may route content transformed specifically for a receiving device. Thus for example voice may be transformed into text and then routed to a fax machine. It may also be possible to transform color images to smell and reroute them to a device able to output smell. Finally, cloning allows the same content to be sent to several devices, and combinations of different transformations for different devices may allow additional dimensions to incoming multi-media. Thus, for example an incoming signal comprising music and voice could be cloned. One of the clones could be transformed into text and transmitted to a monitor able to display text. The other clone could be transmitted to speakers to give high quality reproduction of the music. As a further variation, if the incoming music signal is initially directed at a mobile device, it could first of all be rerouted at the service provider level to a land device so as to support a better data rate and then cloned and redirected for text output as described above. Thus high quality audio play of the music can be combined with a display of the words of the song.
The list below describes typical device/media type combinations for rerouting capability. It is noted that not all the devices are typical external-communication-enabled devices. As mentioned above, non-external-communication enabled devices may not receive original incoming communications but they can route data to other devices and receive data as rerouting targets.
1. Audio and Voice
Audio, and voice type media may be routed from devices including cellular telephones and other cellular or mobile devices including voice enabled PDA's, two-way radios etc., land or fixed line telephones, voice mail boxes (voice messages), Hi-Fi sets, both mobile and non-mobile including radio receivers, MP3 players, Cassette, CD, DVD and VCR players, and the like, and TV sets.
Audio and voice-type media may typically be routed to land or fixed line telephones, cellular telephones and like cellular mobile devices, Hi-Fi sets (mobile and non mobile), car audio systems, TV sets, speakers, and LAN/WAN servers and like infrastructure.
2. Video
Video media may be routed from cellular telephones, especially 2.5G and 3G devices, and other similar hand held devices, DVD and VCR players—both mobile and non-mobile, video cameras and recorders, monitors (screens) including those of TV sets, computer monitors, etc. mobile game devices (for example: Game boy), unified messaging mail boxes, road signs and digital advertisement boards, and LAN/WAN servers and like infrastructure.
Video media may typically be routed to cellular telephones and especially 2.5G and 3G devices, other cellular hand held devices, monitors (screens) including those of TV sets, computer monitors, etc. DVD and VCR players—including both mobile and non-mobile devices, video cameras and recorders, mobile game devices (for example: Game boy), unified messaging mail boxes, road signs and digital advertisement boards, and LAN/WAN servers and like infrastructure etc.
3. Text
Text type data may be routed from cellular telephones where they may be in the form of SMS, email messages and the like, other hand-held devices, unified messaging mail boxes, electronic books, standard computers, and the like.
Such text type data may be routed to monitors (screens)—including TV sets, computer screens, etc. printers, facsimile machines, cellular telephones and other hand held devices, unified messaging mail boxes and LAN/WAN servers and like infrastructure, etc.
4. Images
Image data may typically be routed from digital cameras, facsimile machines, monitors (screens) including TV sets, computer screens, etc., digital vision-oriented equipment such as microscopes, telescopes, binoculars, etc.
Such image data may be routed to cellular telephones, especially 2.5G and 3G devices, other hand held devices, monitors (screens)—including TV sets, computer screens, etc. digital cameras, facsimile machines, printers, unified messaging mail boxes, and LAN/WAN servers and like infrastructure.
As stated earlier, combining the routing capability with the media transformation capability in principle enables routing of any media between any pair of devices appearing in the lists above. Furthermore, combined with cloning, media may be used in different ways at different devices. Such different ways may even be carried out concurrently, thus enabling the simultaneous routing of any media type to any number of devices.
The following is a series of procedure flows for different scenarios.
In the scenarios, appropriate combinations of Routing, Transforming and Cloning an incoming communication are selected to fit the circumstances.
Scenario 1
