Description

The present invention relates to a display device for displaying information and an associated method for ordering. In particular, this invention relates to a display device for receiving and displaying digital data, as well as an associated method for ordering.

Nowadays, for advertising or information purposes, various electronic or electro-mechanical display devices are inserted where the information to be displayed is typically retrieved from a store or via an interface from a programmed device. These display devices mainly only serve for one-way distribution of visual information which cannot be further used by a user in electronic form and/or in an automated manner.

Devices with a radio or television receiver for receiving program accompanying digital data and a display for displaying received program accompanying digital data are known and can be obtained on the market. In particular, it is possible to obtain such devices for digital radio systems DAB (Digital Audio Broadcasting) or for other radio systems such as FM-SWIFT or FM-DARC, or for television receivers with teletext, all of which typically work one-way. With such devices, it is true that information can be received and displayed, but a user cannot still directly receive information about a topic that has been chosen by him.

In European patent application No. EP 259 717, a method is described in which program accompanying data is provided and sent out with content-specific codes for advertising purposes. A user can directly receive information about one or more subject areas, for example real estate advertising, where the user programs a portable receiver with the corresponding code. In addition to radio waves, electromagnetic sources, infrared radiation and ultrasound are also used as a transmission medium, especially for short distances.

In patent application JP08234709, a method for displaying data is described, where advertising data is transmitted via a satellite to a data receiver. Advertising data is stored on a hard disk ("Festplatte") and displayed on a screen. Nationwide advertising data is transmitted by the data receiver, for example over the ISDN or PSTN network, to advertising data servers, where they are displayed on a screen. The procedure aims above all at the widespread distribution of advertising data, and offers a mobile user no opportunity to re-use advertising data in electronic form and/or in an automatic manner.

In patent application WO 94/13107, a set-top terminal for cable television distribution systems is described, where a television set can be connected to a cable television network via the set-top terminal. The set-top terminal according to said patent application WO 94/13107 can be operated by a user by means of mobile remote control over an infrared interface. In addition to special services, such as the generation of picture-in-picture signals for television sets, which do not have such services available, the set-top terminal according to WO 94/13107 makes it possible for a user to view program and channel lists on the television set, to store user-preferred values in the set-top terminal and perform interactive services using menus displayed on the television set, for example directly connected polls (on-line polls) or flight ticket bookings, where data is transferred upstream the cable television network from the set-top terminal to an operations center.

In patent application EP 713335, a system is described where data in a mobile device is recorded wirelessly on a television screen and where transactions can be initiated using the mobile device based on the registered data, where data can be transferred e.g. over the mobile device, e.g. over a mobile radio network to a service centre. In the system according to EP 713335, data is not visible to the user, for example as invisible visual patterns, displayed on the image screen and registered through the mobile device using an optical lens and a photo detector.

In patent application WO 94/15417, a mobile data recording device is integrated into an infrared remote control, which for marketing purposes monitors and records a user's use of a television set. With the aid of a built-in barcode reader, barcodes from purchased products can also be registered with the data recording device according to the aforementioned patent application WO 94/15417.

In patent application DE 4424380, a method is described where program requests relating to encrypted television programs can be sent from an interested user using a mobile device over a mobile radio network to a management device for the program provider in question, where the management device sends corresponding encryption information to an encryption device in the relevant television set, so that the user can see the relevant television program decrypted.

It is an object of this invention to propose a new display device for displaying information and an associated method for ordering.

According to the present invention, this goal is achieved in particular with the features in the characterizing part of the independent claims. Further advantageous embodiments also appear from the dependent claims and the description.

In particular, this aim is achieved with the invention in that the display board in the display device is dimensioned so that information received on a data receiver module, for example program-related data received from a radio or television receiver in the display device, or digital data received from a mobile radio or communication module over a mobile radio network, respectively a fixed network, or digital data read from a data carrier by a reader, and which is displayed on the display device, can be read by users at a distance of several meters, for example, two, three or more meters, and that the display device includes at least a contactless interface that at least some of the received, e.g. program accompanying, digital data can be transferred with portable, personal mobile devices that are not connected to the display device. Depending on the design variants, such a display device has different advantages, for example information, e.g. for advertising purposes, is passed on to users using a radio or television receiver for receiving program accompanying data, without the users themselves having to be equipped with a corresponding receiver module for receiving program accompanying digital data.

Preferably, the display device comprises filter means to receive only the data that is addressed to it, e.g. accompanying digital data. This has the advantage that e.g. several such display devices can specifically be supplied with different information from the same radio or television programme. This can therefore even be achieved, when e.g. the radio or television receiver in the display device is implemented simplified for only one channel.

Depending on the variant, the aforementioned contactless interface in the display device comprises at least one coil and/or an infrared transmitter, which is used to transfer received, for example program-related, digital data in the form of electromagnetic waves, respectively infrared rays, to portable, personal mobile devices , e.g. mobile radio phones. This has the advantage that the data received, e.g. accompanying program data received by the display device, can be passed on to users not only visually, but also that they can be transferred to their mobile devices, where they can, for example, be further processed.

In corresponding variants, the contactless interface in the display device can also receive data from mobile devices and that over the aforementioned coil and/or an infrared receiver. In addition, in a variant, such data that has been received from the display device can be transferred over the contactless interface, for example over mobile radio networks or fixed networks, to a service centre.

In various variants, the display board and the data receiver module are integrated in a common housing, or they are integrated in different housings and connected to each other via an interface.

In a further variant, the display device also comprises a speaker and an amplifier, in order to reproduce audio programmes, respectively audio data, received from the aforementioned data receiver module. This has the advantage that in addition to visual information, acoustic information, such as e.g. stands in connection with visually displayed information, is transferred to users.

In the method for ordering according to the invention, an order is initiated by a user by operating certain operating elements in the aforementioned mobile device, where data, depending on certain of the data received by the display device and transmitted over the contactless interface to the mobile device, for example accompanying the program, digital data, is sent using short messages over a mobile radio network to a service centre. The short messages are, for example, SMS messages, USSD data or similar datagrams, which are, for example, transmitted over a GSM or UMTS network to the service centre. The advantage of this is that the digital data received, for example accompanying the program, can be further used directly and in an automatic way, and that, for example, the one-way transfer of data accompanying the program can be extended to a two-way communication.

The digital data received, for example accompanying the program, which is in connection with the procedure for ordering, preferably includes an identification of the service center, as well as a product or service identification. This identification makes it possible to cancel an order, e.g. according to the method for mobile radio telephones for ordering products or information, which is described in patent application PCT/CH96/00464 (WO 98/28900).

In one variant, the user can use the operating elements in the mobile device to enter and transmit selection commands over the contactless interface to the display device, where the digital data accompanying the program, which is to be transferred from the display device to the mobile device, is thereby selected. The advantage of this is that the user can directly decide the data that he wants transferred.

In various variants, the contactless interface in the mobile phone is designed so that an infrared transmitter and receiver are integrated into the mobile device's housing, or that a coil is implemented in the mobile device or in a chip card that is remotely connected to the mobile device.

In one variant, certain of the for example program-related data that is transferred to the mobile device is filtered in the mobile device on the basis of user profiles that are, for example, stored on a chip card. This has the advantage that data that the user is interested in can be automatically transferred to the user's mobile device, where e.g. for further treatment .

In one variant, data, e.g. accompanying program digital data, which has been transferred to the aforementioned mobile device and which has been received by the mobile device, can be displayed on a display unit in the mobile device and browsed, selected and, for example, further processed by predefined software functions in the chip card by the user using operating elements on the mobile device.

In the following, an embodiment of the present invention is described by means of an example. The embodiment example is illustrated by the only attached figure showing a schematic block diagram, which comprises a data transmitter, a display device, a mobile radio telephone with a chip card, as well as a mobile radio network and a service center connected thereto.

The following example refers to a radio transmitter 2 as data transmitter 2 and, in turn, to a radio receiver 13,13' for receiving program accompanying data from radio programs that are broadcast from this radio transmitter 2. It must nevertheless be immediately maintained in detail that the invention can also be used for other combinations: Broadcasting of television sets with accompanying program data, for example teletext information, by a television transmitter 2 which can be received by an associated television receiver 13,13' and displayed, for example, on a television picture screen 12, e.g. a conventional electronic picture tube or an LCD or plasma screen (display).

Sending short messages, e.g. SMS short messages or USSD data, or of broadcast messages over a mobile radio network 5, such as a GSM or UMTS network at a corresponding transmitter 51, for example a communication server

(server) in a service center 51 and receiving this data through an associated mobile radio module 13.

Transmission of digital data from a transmitter 51, e.g. a communication server in a service center 51, over a fixed network 5, such as the public switched telephone network (PSTN) or the Internet, to an associated communication module 13. Reading of digital data using a reader 13, 13' from a data carrier not shown, e.g. e.g. a chip card, a CD-ROM or a floppy disk.

In the detailed embodiment, reference number 2 shows the above-mentioned radio transmitter, for example a transmitter for a nationwide or local radio station or a transmitter for coverage of a very limited geographical area, e.g. a fair or exhibition area. The radio transmitter is e.g. an FM transmitter which, in particular, can also send digital data according to the programme. Transmission of program accompanying data in connection with the radio program is primarily used in the digital radio system DAB (digital audio broadcasting) or in other radio systems such as FM-SWIFT or FM-DARC. The DAB technology, for example, makes it possible to transmit radio programs as well as program accompanying services (program associated data, PAD). For example, with the help of DAB, data can be transmitted in eight addressable channels with a capacity at any time of 150 Kbit, where addressing of these channels makes it possible to send data to a separately addressed receiver, a defined group of several receivers (multicast ), or to all recipients (broadcast) .

As indicated by both of the one-way arrows emanating from the radio transmitter 2, the program accompanying digital data, for example advertising information about products and/or services, is spread together with any audio programs from the transmitter and is received by an associated radio receiver 13,13', which receives and these accompanying program digital data and decodes them with suitable means, i.e. the radio receiver 13,13' is for example a radio receiver 13,13' or a radio receiver 13,13' for receiving program accompanying data according to FM-SWIFT, FM-DARC or according to another method . Depending on the design, the radio receiver 13,13' is able to recognize the above-mentioned addresses for the various data channels, and to receive or ignore data from these channels in accordance with these addresses.

Such a radio receiver 13, 13' is a component of the display device 1 according to the invention. Depending on the design variant, the radio receiver 13 is integrated in the same housing as the display board 12, or the radio receiver 13' and the display board 12 are integrated in separate housings and connected via an interface 14 which is indicated by the dashed line 14. Optionally, the interface 14 can be made by means known to a person skilled in the art, e.g. as serial or parallel interfaces, using a fixed or detachable cable connection, or over a contactless interface.

In one possible embodiment, any audio signal sent and received from the radio receiver 13, 13' is forwarded via a schematically indicated internal connection to an amplifier 19, for example a low-frequency amplifier known to those skilled in the art, is amplified by this, and the amplified electrical signal is led to one or more loudspeakers 20. As shown in the figure, both the amplifier 19 and the loudspeaker 20 can be integrated in the housing 11 or the amplifier 19 and/or the loudspeaker 20 can be connected to the radio receiver 13, 13' via an external fixed or detachable cable connection, not shown.

Via a similarly schematically shown connection, the radio receiver 13,13' forwards the received digital data accompanying the program to a processing module 17. If the function of decoding the above-mentioned channel addresses is not taken over by the radio receiver 13,13', the processing module 17 is responsible for recognizing the different data channels' addresses, and to receive or ignore data from the data channels in accordance with those addresses.

The received digital data accompanying the program is intermediately stored by the processing module 17 and led to the display board 12 via the schematically shown internal connection for display. The display board 12 can e.g. be an electronic, electromechanical or other display device known to the person skilled in the art. Depending on the design, the display control, i.e. control of how data is to be displayed on the display board, can be taken over by a corresponding programmed software function in the processing module 17 or by a corresponding functionality in the display board 12. For example, the same information, e.g. an advertisement for one or more product(s) and/or services from a specific provider is displayed statically for a longer period of time, or different information, for example advertisements from different providers or several products and/or services from the same provider, can be displayed alternately on a line - or lateral image displacement (scrolling). The processing module 17 comprises, for example, a processor and a storage medium, where the storage medium not only serves for intermediate storage of the received program accompanying data, but also for storing programmed processing, communication and control functions. The processing module 17 can be designed and realized by a specialist, e.g. with components that are common in the trade.

At least some of the received program data is forwarded from the processing module 17 via a schematically shown internal connection also to an electronics module 18. This electronics module 18 comprises an electronic switch circuit which can be designed and realized by the person skilled in the art so that it receives data from the processing module 17 via the internal connection and forwards them as corresponding analogue or digital signals over a contactless interface for forwarding to this. The contactless interface includes e.g. a coil 15, and with the help of this data is sent out as electromagnetic waves, for example with a frequency of 13.56 MHz or with another frequency, and/or an infrared transmitter 16 where data is sent out as infrared rays. In the opposite direction, the switch circuit developed by a person skilled in the art can receive signals induced in the electric coil 15 by an external magnetic field from a mobile device 3, and/or receive infrared rays radiated from the mobile device via the infrared receiver 16, and forward these as data on the schematically shown internal connection to the processing module 17.

Depending on the design variant, the electronics module 18 may contain only one switch circuit for a coil or an infrared transmitter/receiver, or it may comprise two different switch circuits, one for the coil and one for the infrared transmitter/receiver, or it may contain a common combined switch circuit. The switch circuit can e.g. is implemented as an integrated switch circuit in the electronics module 18. Known switch circuits for inductive contactless interfaces are used, among other things, already in chip cards and are known under the designation CCI (contactfree chipcard interface). The contactless infrared communication is preferably based on a known standard, e.g. on the IrDA protocol (Infrared Data Association). The commercially available infrared transmitter/receiver 16 is either integrated directly into the housing 11 or placed on the surface of the housing 11. In a variant, the person skilled in the art can also decide to combine the processing module 17 with the electronics module 18.

As illustrated in the figure, the display device 1 can communicate over the contactless interface with an external, portable and personal mobile device 3. The mobile device 3 is, for example, a mobile radio telephone 3, but it can also be another personal, portable device designed and constructed especially for the purpose with communicating with the display device according to the invention. The mobile device comprises a contactless interface, as described in the applicant's patent application PCT/CH97/00237 (WO 98/58509), which e.g. comprises an infrared transmitter/receiver 31 which is integrated on or in the housing 3 of the mobile device, or a coil 32 which is integrated in the mobile device 3, or that the mobile device comprises a chip card 35, as described in the applicant's patent application PCT/CH98/00036 (WO 98/58510), which is releasably connected to the mobile device 3 and comprises a coil 36, or that the mobile device 3 is releasably connected to an expansion module not shown, as described in the applicant's patent application PCT/CH98/00211 (WO 99/60713), which includes a coil and/or an infrared transmitter/receiver.

The maximum communication distance between the display device 1 and the external mobile device 3 for direct communication over the contactless interface without, for example, using the radio telephone components in the mobile radio telephone 3, depends, for example, both on the properties of the coil 15, 32, 36, which e.g. can be produced by winding a wire or by a preferred other suitable technique, and by transmitter power, which on the mobile device 3's side is typically limited so that its energy reserve is not burdened too heavily. A range of e.g. several meters can easily be realized using conventional techniques. It is important to note that the housing 11 is not electromagnetically shielded at the location where the coil 15 is located, so that a radio connection with the external mobile device can be set up. Also in the further or alternative design variants with an infrared transmitter/receiver 16, the maximum communication distance depends on the transmitter power, which is again limited on the mobile device 3's side so that its energy reserves are not burdened too heavily. In an embodiment with known technology and components, the range can amount to a few meters without problems. Above all, the communication path between the infrared transmitters/receivers in the display device 1 and the mobile device 3 must be free of obstacles that cannot be passed by infrared rays. It should also be mentioned here that the communication distance in direct communication over the contactless interface can absolutely also depend on the direction of communication, so that the display device 1 radiates signals with greater power than the mobile device 3, and can consequently transmit data over a greater distance to external mobile devices 3 than in it is in the reverse case.

In one variant, the processing module is programmed so that it sends out the intermediate stored program accompanying digital data periodically, as described above, over contactless interfaces, for example as previously mentioned with a transmitter effect that is greater than the mobile device's 3. The thus sent data is received of the mobile device in the display device's 1 transmission range. In one variant, they are filtered on the basis of user profiles which are, for example, stored on the chip card 35 which is releasably connected to the mobile device 3, where content-specific codes from the accompanying program data received by the mobile device 3 are compared with corresponding codes in the user profile, for example through corresponding programmed software functions on the chip card 35, for example a SIM card (subscriber identity module). In this way, the mobile device 3 only receives the data that the user is interested in according to his user profile, respectively, depending on the application, for the data that the user has registered for or paid for. For example, a user can enter a user profile on his chip card 35 that contains codes for a specific group of products and/or services or he can pay for a user profile that allows him to receive certain information and data via his mobile device 3.

In an alternative or additional variant, the processing module 17 is programmed so that it sends out certain buffered program accompanying digital data on special request from a mobile device 3, where, after use, the sent data can at any time be received and allowed to be received on all mobile devices 3 in the transmission area of the display device 1, or where the data transmitted in this way, for example, contains an identification, which forms the basis for the mobile device 3 in question to determine whether it is data that it has requested. In the event that it is necessary for the application, data can also be transferred securely, for example with the TTP method (trusted third party) or a PTP method (point-to-point). For encryption of the data exchange over the contactless interface, between the display device 1 and an external mobile device 3, a DEA, DES, TDES, RSA or ECC security algorithm can also be used. In the event that it is further necessary for the application, an IMSI (international mobile subscriber identification) or an IDUI (international debit user identification) can also be used which is stored on the chip card 35 for identification and authentication of the user of the mobile device 3, and which is transmitted over the contactless interface to the display device 1, where the above-mentioned TTP method or a similar method can be used for authentication.

The direct collection of data from the user takes place, for example, so that the user sees information that is interesting to them, e.g. an advertisement with several choices, displayed on the display device 1 display board 12. This may include recommended products and/or services, such as e.g. is equipped with an identification number. It is nevertheless also possible that the instructions for obtaining the displayed information are given over the speaker 20 of the display device 1. The user of the mobile device requests information, by e.g. enters the identification number or follows the specified instructions using the mobile device's 3 operating elements" 34, where corresponding selection commands are sent to the display device 1 via the mobile device's 3 contactless interface. It may therefore be necessary for this process to be initiated and terminated using predefined keys on the mobile device 3 , which for example starts and ends a program on the mobile device 3's chip card 35 which is responsible for the data request. In the display device 1, selection commands are received over the contactless interface and forwarded to the processing module 17 as described above, where they are received and processed by programmed communication functions. This means that obtained information, for example the corresponding digital data accompanying the program, e.g. information about a specific product or service, is sent out from the display device 1 and transferred to the mobile device(s) 3, as described above. software can be developed by a professional for the processing module 17 and for the chip card 35, for example a SIM card.

At least some of the digital data accompanying the program can advantageously contain a product or service identification, as well as e.g. an identification of a service center 41, over which orders for these products and/or services can be completed. It is also possible that the radio transmitter 2 can act as a service center and can receive e.g. orders of information, and that the accompanying digital data related to the radio transmitter 2 can identify it as a service centre. On the basis of such program-following digital data (with product and service identifications), which is received by the mobile device as described over the contactless interface from the display device 1, the user of the mobile device 3 can initiate an order for the mentioned products or services. For associated data that is requested and received by means of selection commands from the display device 1, the order can for example be initiated so that a predefined key of the operating elements 32 on the mobile device 3 is pressed. In the event that corresponding data for several products and/or services is received by the mobile device 3, these can be displayed on the mobile device 3's display unit 33 and browsed and selected using the operating elements 34, and for a selected product or a selected service the order can be initiated for example once again with the above-mentioned function keys. The person skilled in the art will understand that for selected data, instead of the order, other predefined software functions can also be started and performed on the chip card 35. After initiation of the order, the mentioned product or service identifications are sent by means of a short message, e.g. an SMS short message, USSD data or a similar datagram, over a mobile radio network 4, e.g. a GSM or UMTS network, to the identified service center 41 (or 2). In order to prevent an order being entered incorrectly, additional confirmation steps can of course be built in, which will not be detailed here. Both reception of the accompanying digital data via the contactless interface and the course of the order initiation and order processing can for example be carried out by corresponding programmed software functions on the chip card 35 which can be developed by a professional. Transmission and processing of data in short messages to this and in the service center 41 takes place, for example, with the SICAP method, which is described among other things in EP 689 368, according to a similar method or based on WAP (wireless application protocol). A procedure for ordering products or information for a mobile radio telephone 3, such as e.g. can be used here, is described in the applicant's patent application PCT/CH96/00464 (WO 98/28900).

As already indicated, the display device 1 according to the invention is suitable, for example, for displaying and forwarding advertising information about products and/or services, which can be sent out from a radio transmitter 2 with the help of accompanying digital data, and for the associated method for ordering these the products and/or services from a service center 41 (or 2) using a mobile device 3. The concrete investment possibilities are almost unlimited and include, for example, display devices at fairs and exhibition areas, in amusement parks and shopping centres, at airports and stations, in financial centers and stock exchange places, or in other localities visited by a large public.

Not only the investment possibilities, but also in general also the application possibilities with the described invention are almost limitless and in no case limited only by the given examples of advertising for and ordering products and services. Particularly for information services or access rights to locally restricted services, it is also possible, for example, to extend only the order also to payment and delivery. E.g. an advertisement for an event can be displayed on the display device 1, for example a sports event or a tourist attraction such as a boat trip or cable car trip (Bergbahnfart), and the user can submit a corresponding order for one or more admission tickets in short messages over the mobile radio network 4 using the data accompanying the program which is received via the display device 1, which he can also pay at the same time using an amount of money stored on the chip card 35. In return, he receives, for example, an access key for one or more people sent over the mobile radio network 4 and placed on the chip card 35. When visiting the event, the access key is sent over the mobile device's 3 contactless interface to an external device not shown, in this case an access control, and he is given corresponding access.

At this point, it should once again be mentioned that thanks to the addressing and filtering option of program accompanying digital data in different channels, it is possible with a radio transmitter 2 to provide different display devices 1 with different information on a transmission frequency; thus, for example, several display devices 1 in different places can be supplied with targeted and individual information.

In one variant, the display device 1 also includes a transmission module which is schematically indicated in the figure as a component of the data receiver module 13, for transmission of data over a fixed network 5, for example the public switched telephone network (PSTN) or the internet, or over a mobile radio network 5, for example a GSM or UMTS network, to a service center 51. Via this transmission module 13, for example, data can be received as described above over the contactless interface, further sent to the processing module 17, and from this received and forwarded to the transmitter module 13 using corresponding programmed communication functions, to an external service center 51 for further processing there and/or transferred for storage.

As has already been mentioned, the data receiver module 13, 13' in the display device 1 according to the invention can not only be realized by means of a radio receiver 13, 13' for receiving program accompanying data, but the data receiver module 13, 13' can also be a television receiver 13, 13' for receiving programme-related data, a mobile radio module 13 for receiving and transmitting digital data over a mobile radio network 5, a communication module 13 for receiving and transmitting digital data over a fixed network 5, or a reader 13,13' for reading digital data from a data carrier. Although not all combination possibilities are explicitly shown in the figure, it is understandable to a person skilled in the art that in certain applications it makes sense to combine some of these variants. For example, as mentioned above, it may make sense to combine a transmission module 13 for transmitting data over a fixed network 5 or a mobile radio network 5 to a service center 51 with a specific data receiver module. Moreover, the person skilled in the art can also assume that the different design variants of the data receiver module 13, 13', as already described for the radio receiver, are integrated in the same housing 11 as the display board 12, or that these data receiver modules and the display board 12 are integrated in separate housings and connected above the interface 14 indicated by the dashed line 14.

In addition, with the various data receiver modules 13, 13', it may also be sensible to add any audio signals to one or more loudspeakers 20 via a schematically indicated internal connection via the amplifier 19 described above. Above all, the person skilled in the art will know that depending on the design of the data receiver modules 13, 13', either the data receiver module 13, 13' or the processing module 17, or possibly the amplifier 19, must be provided with corresponding components or programmed functions to transform, for example, digital audio data into a analogue audio signal, or e.g. to separate the accompanying program data, the visual signal and the audio signal.

It is also clear to a person skilled in the art that the processing module 17 and the internal connection which is indicated schematically in the figure between the data receiver module 13, 13' and the processing module 17 must accordingly be designed and realized differently depending on the design of the data receiver module 13, 13'.

Alongside the installation and operation of the display device 1, chip cards 35, e.g. SIM cards are added with the necessary functionality for carrying out the method according to the invention for ordering as well as user profiles selected by the user. For example, it is also possible to rent out the display device 1 to a provider of services and/or products and/or demand a commission for each product or service ordered in this way.
