`specifically for redirecting calls between satellite and terres(cid:173)

`10 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 lim-
`ited 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.

`device. Data may be a package or a stream. Such a stream may
`be unidirectional, bi-directional or multidirectional.

`BRIEF DESCRIPTION OF THE DRAWINGS
`
`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 tlie cause of providing what is believed to be the most
`useful and readily understood description of tlie 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 understand(cid:173)
`ing 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:

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`The capability of routing of multi-media content (possibly
`including media transformation and multiplication, i.e. clon(cid:173)
`ing) 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
`20 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
`tliat say is limited by inferior data rate, processing power,
`25 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
`30 device. Furthermore, as will be explained below, the ability to
`route content from non-mobile, tliat is land or fixed devices to
`nearby mobile and oilier devices permits a range of possibili(cid:173)
`ties for use which is currently not provided for.
`For example, the ability to route an incoming phone call,
`35 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 infor-
`40 mation. Such rerouting may also enhance the user's ability to
`share the information with other people or with computer
`applications, for example applications tliat capture informa(cid:173)
`tion displayed on the monitor and use it to trigger other
`events. Such applications can easily be run on a PC or laptop
`45 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
`50 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 inven(cid:173)
`tion provides an ability to route an incoming voice message
`from say a mobile device or voice mailbox to a facsimile
`55 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
`60 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 capa-
`65 bility may be highly desirable for people with special needs(cid:173)
`impaired senses (hearing, vision) who may use such a capa(cid:173)
`bility to receive information in a form more usable to them.

`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 trans(cid:173)
`missions. Similarly, it announces its becoming available.
`Announcements may be periodically repeated. As an alterna- 25
`tive 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 30
`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 (trans- 35
`mitting) 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 ofuse informa(cid:173)
`tion using a barcode. The sticker may be scanned and com(cid:173)
`prehended by the scout devices 32. In addition to a sticker, a 40
`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 45
`color display alongside the barcode. The color display may be
`changed electronically or mechanically by the device to indi(cid:173)
`cate different states, and can be read optically along with the
`barcode.
`The scout device 32 is responsible for scanning the envi- 50
`ronment 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 peri(cid:173)
`odically and/or upon demand.
`Device library 34 contains information needed for commu(cid:173)
`nicating with various devices. Such information may typi(cid:173)
`cally include usage related information as well as technical
`information regarding expected media formats and transmis(cid:173)
`sion technology specifications, including protocols, used by
`the device type. It may also contains pre-defined user prefer(cid:173)
`ences 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 pref(cid:173)
`erences over a network, or it may simply capture user prefer-
`
`8
`ences 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 ofFIG. 2 may be physi(cid:173)
`cally packaged, for example as a card, a chip or an attached
`stand-alone unit. The apparatus may also be realized as soft(cid:173)
`ware within another apparatus, host device-for example, on
`a personal computer (PC), cell phone, a personal digital assis-
`10 tant (PDA) or other standard electronic devices. In any case,
`the host apparatus preferably possesses its own transmission
`and receiving capabilities, or is connected, perhaps via a
`network, to another device that does have such capabilities.
`For example, a host cellular telephone may use already
`15 installed IR for scouting and announcing or any of the previ(cid:173)
`ously 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 interac(cid:173)
`tion 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, tenns,
`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 ofFIG. 2 or obtained from remote
`sources.
`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 modi(cid:173)
`fication preferably provides some level of firewall protection
`for both receiving and transmitting components. Such pro(cid:173)
`tection may comprise identification and/or authentication,
`and may comprise restrictions on routing or receiving infor-
`mation 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:
`Infra-red (IR)
`Microwave
`Radio (any suitable frequency)
`Sound waves
`Ultrasound
`Wire (and cable) transmission technologies
`Light (visible)
`Laser
`Chemical (mainly smell)
