- Fig. 2 shows the architecture of a display control system according to the invention in the case where the voice communication device as well as the display terminal of the receiver's station are combined in a single member; - Fig. 3 shows a block diagram of the use of the display control system as described with reference to FIG. 2; - Fig. 4 shows the architecture of a display control system according to the invention in the case where the voice communication device as well as the display terminal of the receiver's station are two separate bodies; and - Fig. 5 shows a block diagram of the use of the display control system as described with reference to FIG. 4.

 In Figure 1, there is shown a display control system according to the prior art.

 This system includes, a microcomputer 1 located at an information receiver station and a microcomputer 2 located at an information provider station. These two microcomputers are connected to an Internet network 3 via a PSTN, ISDN, ADSL, cable, LAN, or other modem type connection.

 In addition, the microcomputers 1,2 have phonic means 4,5 common on multimedia microcomputers and navigation software, (not shown). In addition, they respectively integrate functions 6,7 allowing the passage of the voice V over the Internet commonly called "VOIP gateway".

 The establishment and monitoring of voice communication is carried out by a computer server 9.

 The information to be communicated to the receiver is stored in a database 10 connected to the network 3.

 The synchronization of the navigation software of the supplier and of the receiver is ensured by a synchronization server 11.

 The phonic means 4.5 of the microcomputers 1,2 acquire and restore the voice V. This voice V is relayed over the network 3 via the VOIP gateways 6.7.

<Desc / Clms Page number 5>

 In juxtaposition with this voice communication, when the supplier validates an Internet link, it sends a request D transmitted to the computer server 9 responsible for extracting from the database 10 information N associated with this request D. This information N is transmitted and displayed on the microcomputer 2 of the supplier's station. The synchronization server 11 detects the display of information N on the microcomputer 2 of the supplier's station. If this information N has undergone prior processing in order to allow sharing, the synchronization server 11 transmits it to the microcomputer 1 of the receiver's station, which displays it.

 We see that such an architecture requires a complex and bulky supplier position and only allows a limited amount of information to be shared.

 Figure 2 shows a first embodiment of a display control system according to the invention.

 This system includes a microcomputer 12 located at an information receiver R station, and a key telephone 14 located at a provider station F.

 The microcomputer 12 is connected to the internet network 3 via a PSTN, ISDN, ADSL, cable, LAN, or other type of connection. It includes a VOIP gateway 13 intended to relay the voice V over the internet network 3. It further comprises, phonic means 16 common on multimedia computers and has navigation software (not shown).

 The telephone 14 is connected to the Internet network 3 via a VOIP gateway 18. It integrates phonic means 17 common on the telephones. In this example, the telephone 14 is a landline telephone. In another configuration, it is a mobile phone.

 The keys 15, of the telephone 14, generate, during use, signals S, commonly called DTMF. These signals S or DTMF, command means 19 for extracting information to be displayed on the receiver's station R.

 These extraction means 19 establish the correspondence between a DTMF or a DTMF sequence and information 1 to be displayed, as a function of a correspondence table (not shown) defined by the supplier F. For example, upon receipt of a sequence # 10, composed using the keys

<Desc / Clms Page number 6>

 15 from telephone 14, a cover page in French will be sent to receiver R's station, and upon receipt of a sequence # 20, it will be a page in English.

 The website of the supplier F is hosted by a computer server 20 belonging, for example, to a third party T. This computer server 20, thanks to software means (not shown), participates in the establishment of the voice communication V.

 The information 1 to be communicated to the receiver R is stored in a database 21 connected to the network 3, and belonging, for example, to the same third party T. This information 1 does not undergo any prior processing. In addition, they may belong to another third party.

 In this example, only the microcomputer 12 integrates the extraction means 19. In another architecture, the information extraction means can be distributed between the microcomputer 12 and the computer server 20, the base of given 21 or a combination of these two elements.

 In addition, the computer server 20 and the database 21 can belong to the same third party, to different third parties or to the supplier F.

 The operation of the system described with reference to FIG. 2 is as follows.

 At the initiation of voice communication V, the computer server 20 generates and sends, to the microcomputer 12 of the receiver's station R, an Internet page comprising in its code a correspondence table between the signals S to be received from the provider's station F and the addresses of the information 1 to be displayed. This page constitutes the means 19 for extracting information.

 The phonic means 16, 17 of the microcomputer 12 and of the telephone 14, acquire and restore the voice V. This voice V, is relayed over the network 3 via the VOIP gateways 13, 18.

 In parallel with this voice communication, when the supplier F activates one or more keys 15 of his telephone 14, this generates the signals S, which pass in juxtaposition with the voice communication V.

 These signals S are transmitted to the extraction means 19 present on the microcomputer 12 of the receiver station R. These extraction means 19 will

<Desc / Clms Page number 7>

 search the database 21 for information 1 associated with the signals S. This information 1 is transmitted to the microcomputer 12 which displays it.

 Figure 3 shows a sequence of connection and use of the system of Figure 2.

HearMe,...). This figure shows: - a third party T managing voice communication thanks to the computer server 20 for an information supplier F. The standard website of supplier F is hosted by the third party T on this same computer server 20. The supplier F has configured, for example online and via an Internet-type interface offered by the third party T, a table of correspondence between addresses of Internet pages whose display he wishes to order and DTMFs. This information is saved in the database 21 belonging to the third party T; - the telephone 14 with keys 15 connected to the Internet network 3 via the VOIP gateway 18 of said station of the supplier F; and the multimedia microcomputer 12 of said receiver station R, connected to the Internet, having navigation software (not shown) supporting for example JavaScript and software making it possible to manage voice communication in H323 or SIP mode, for example of the ActiveX type (not shown). Software of this kind is available on the market for voice management software on the Internet (example: Vocaltec, Audiotalk,

HearMe ...).

The receiver R connects to the site of the supplier F hosted by the computer server 20 of the third party T.

 On the internet page obtained at the receiver's station R, an HTML link named for example "Contact us" is available. The receiver R validates this link (step 50) which results, on his microcomputer 12, either by the display of a new Internet window, or by the addition of a window in the existing Internet window (step 60).

 This new window will request the download of the code managing the voice communication (step 70). This code is adapted to supplier F and in particular to the configuration of the Internet pages to be displayed according to the events occurring on the network (connection, call request, busy line ...) and DTMF signals.

<Desc / Clms Page number 8>

 The computer server 20 sends a request to the database 21 storing the Internet pages to be displayed, passing in parameter the identity of the supplier F and for example the language of the Internet site consulted (step 80).

 The supplier F being represented within the database 21, the latter returns to the computer server 20, the correspondence table between the addresses of the Internet pages to be displayed adapted to the language of the website of the supplier F and the events occurring on the network or the DTMFs juxtaposed with voice communication (step 90), as well as a set of elements concerning the display mode of the Internet page: new window of 1/4 screen size,% screen, full screen , or in the window in use for current navigation, location in the case of a new window (top left, center of the screen, ...). The computer server 20 dynamically generates the personalized Internet page with the configuration of the supplier F.

This page constitutes the means 19 for extracting the information 1 to be displayed.

 This page is downloaded by the navigation software of the microcomputer 12 of the receiver's station R within the window dedicated to the management of voice communication (step 100). This web page also has a voice call button (HTML or image link).

 The receiver R validates this call button to request the computer server 20 to establish voice communication (step 110).

 The computer server 20 performs a validity test of the voice communication request by checking, for example, the call time, the availability of the service, or the like. If this test is successful, it begins the procedure of vocal connection.

 The VOIP H323 (or SIP) communication logic is being implemented (call authorization by a security system, search for the VOIP gateway allowing call termination, etc.), H323 voice communication in packet mode s established between the ActiveX software present on the microcomputer 12 of the receiver's station R and the VOIP gateway 18 of the provider's station F (step 120), and another communication in PSTN circuit mode is established between the VOIP gateway 18 and the telephone terminal 14 called (step 130), the VOIP gateway 18 ensuring the connection of the two communications.

 Voice communication is then established between the microcomputer 12 of the receiver's station R and the telephone 14 of the provider's station F (step 140).

<Desc / Clms Page number 9>

 The events intervening on the network generated from the call establishment request to the call disconnection are managed by the ActiveX software present on the microcomputer 12 of the receiver's station R. This software has an interface application programming, or API, of the JavaScript type which allows the code of the Internet page ensuring the management of voice communication on the one hand to activate events locally from the Internet page (request for establishment of the '' call via the call button, request to disconnect voice communication, request to send DTMF, ...), and also to be informed of events on the network (authorization accepted by the security system, VOIP gateway accepting H323 communication, VOIP gateway dialing phase, ringing of the called terminal, connection of the called terminal, disconnection of the call, etc.). In particular, the APt detects the reception of a DTMF code or sequence generated by the supplier F, using the keys 15 of its telephone 14 (step 150), and transmitted in juxtaposition with the voice communication, by the VOIP gateway 18 (step 160).

 The code of the Internet page ensuring the management of voice communication processes the various events received via the API of the ActiveX software and sent from JavaScript functions, according to the correspondence table received at the start of the sequence. . For example, on reception of the DTMF code 0 from the API via a DTMF reception function, the JavaScript code requests the Internet page to be displayed (step 170) including the Internet address, commonly called URL , pre-programmed was dynamically inserted into the code when it was downloaded (standard Javascript function: location. href = http: // www. site X. com / O key. HTML), which page will be extracted from the database. data 21 by the microcomputer 12, received (step 180) and displayed.

 The information page, like the database 21 on which it resides, can belong to third party T, another third party or supplier F.

 In this example, the Internet page transmitted to the receiver's station R, and including the correspondence table, is dynamically generated by the computer server 20 because it must take account of the supplier F (The third party T can manage several information suppliers) .

<Desc / Clms Page number 10>

 In the case where supplier F owns the storage, retrieval systems and servers, he can insert directly, in his code processing voice communication, the processing and detection of DTMF codes or sequences.

 The Internet page thus defined is then said to be static as opposed to a dynamic page.

 Figure 4 shows a second embodiment of a display control system according to the invention.

 In this figure, the components common with those of the system described with reference to FIG. 2 will bear the same reference numbers.

 This system includes a display terminal 22 and a telephone 23 located at an information receiver R station, and a key telephone 14 located at a supplier station F.

 The display terminal 22 is connected to the internet network 3 via a connection of the PSTN, ISDN, ADSL, cable, LAN, or other modem type. It has navigation software (not shown).

 The telephones 14, 23 are connected externally to the internet network in a standard manner (PSTN network) and integrate phonic means 17, 24 common on the telephones. In this example, the telephones 14, 23 are fixed telephones. In another configuration, these are mobile phones.

 The keys 15, of the telephone 14, generate the use of the signals S, commonly called DTMF. These signals S or DTMF, command means 25,26 for extracting information to be displayed on the receiver's station R.

 These extraction means 25, 26 establish the correspondence between a DTMF or a DTMF sequence and an item of information 1 to be displayed, according to a correspondence table (not shown) defined by the supplier F and described with reference to FIG. 2.

 The website of the supplier F is hosted by a computer server 20 belonging, for example, to a third party T.

 A terminating server 27, on the one hand establishes, using software means and in response to a request sent on the network 3 originating from the receiver's station R, a voice communication V external to the network 3, and on the other

<Desc / Clms Page number 11>

 part detects the signals S in order to transmit them to the extraction means 25, 26.

The abutment server 27 belongs, for example, to the same third party T.

 The information 1 to be communicated to the receiver R is stored in a database 21 connected to the network 3, and belonging, for example, to the same third party T. This information 1 does not undergo any prior processing. In addition, they may belong to another third party.

 In this example, the extraction means 25, 26 are distributed between the abutment server 27 and the display device 22 of the receiver (R). In another architecture, they can be distributed between the display device 22 and the computer server 20, the database 21 or a combination of these two elements and the abutment server 27.

 In addition, the computer server 20, the database 21, and the abutment server 27, can belong to the same third party, to different third parties or to the supplier F.

 The operation of the system described with reference to FIG. 4 is as follows.

 At the request from the display device 22 of the receiver R through the network 3, the abutment server 27 establishes and monitors a telephone communication, outside the network 3, between the telephone 23 of the receiver's station R and the telephone 14 from the position of supplier F.

 The phonic means 17.24 of the telephones 14.23 acquire and restore the voice V.

 In parallel with this voice communication, when the supplier F activates one or more keys 15 of his telephone 14, this generates the signals S, which pass in juxtaposition with the voice communication V.

 These signals S are detected by the abutment server 27 which integrates the extraction means 25. They extract from the database 21 I address information 1 associated with the signals S. The extraction means 26 present on the display device 22 of the receiver R, by regularly interrogating the abutment server 27, receive this address. They go to the database 21 for the corresponding information 1 and transmit it to the device 22 which displays it.

 Figure 5 shows a sequence of connection and use of the system of Figure 4.

<Desc / Clms Page number 12>

This figure shows: - a third party T managing voice communication thanks to the abutment server 27 for an information supplier F. The standard website of supplier F is hosted by third party T on a computer server 20. The supplier F has configured, for example online and via an Internet-type interface offered by third party T, a table of correspondence between addresses of Internet pages whose display he wishes to order and DTMFs. This information is saved in the database 21 belonging to the third party T; - the telephone 14 with keys 15 of said station of the supplier F; and - the display terminal 22 connected to the Internet, having navigation software (not shown) supporting for example JavaScript and the telephone 23 of said receiver station R.

 The receiver R connects to the site of the supplier F hosted by the computer server 20 of the third party T.

 On the Internet page obtained at the receiver's station R, an HTML link named for example "Contact us" is available. The receiver R validates this link (step 200), which results, on its display system 22, either by the display of a new Internet window, or by the addition of a window in the existing Internet window (step 210).

 This new window, present on the display terminal 22 of the receiver R, ensures the availability of the telephone number 23 of the station of the receiver R and the saving of the local parameters, and makes available to the receiver R a button d voice call (HTML or image link).

 The receiver R validates the call button to request the computer server 20 to establish voice communication (step 220).

 The computer server 20 transfers this request to the abutment server 27 (step 230).

 In another configuration, this request is sent directly to the abutment server 27.

 The abutment server 27 interrogates the database 21 (step 240) in order to receive in response (step 250), the characteristic parameters of the supplier F (telephone number of the supplier F, IP address, etc.).

<Desc / Clms Page number 13>

 The supplier F being represented within the database 21, the latter returns to the abutment server 27 the correspondence table between the addresses of the Internet pages to be displayed adapted to the language of the website of the supplier F and the events involved on the network or the DTMFs (step 250) as well as a set of elements concerning the display mode of the Internet page: new window of 1/4 screen size, 1/2 screen, full screen, or in the window in use for current navigation, location in the case of a new window (top left, center of the screen, ...).

The abutment server 27 then has distributed means 25 for extracting information.

 The abutment server 27 performs a validity test of the voice communication request by checking, for example, the call time, the acknowledgment of the access rights to the service, or the like.

 If the validity test of the request is conclusive, the abutment server 27 sends to the display device 22 of the receiver's station R (step 260), an internet page comprising a function, for example of the Javascript type, for interrogation periodic. This page constitutes the extraction means 26.

 Consequently, the extraction means 26, present on the display device 22 of the receiver R, regularly interrogate the abutment server 27 (steps 270a to 270n). They retrieve either an instruction to remain in the current state in the event that there has been no event received, or an Internet address corresponding to an event (connection in progress, line busy, ...).

 The abutment server 27 then initiates the voice connection procedure.

 It checks the availability of the telephone 14 of the station of the supplier F (step 280). When it is assured of the possibility of response, it checks the availability of the telephone 23 of the receiver's station R (step 290).

 The end-user server 27 manages the connection of the telephone 14 of the supplier's station F and the telephone 23 of the receiver's station R in order to establish voice communication V outside the Internet network 3 (step 300).

 The abutment server 27, on the one hand permanently monitors the telephone communication outside the network 3, and on the other hand detects the reception in juxtaposition with the voice communication, of a code or of a DTMF sequence activated by the supplier F (step 310) using the keys 15

<Desc / Clms Page number 14>

 of his telephone 14 in order to control the display of information 1 on the display device 22 of the receiver R.

 The abutment server 27, having distributed extraction means 25 comprising the correspondence table, makes available, for example in a dedicated memory area, the address of the Internet page, or URL, associated with the DTMF code received.

 On the occasion of a response given to the periodic interrogation (step 270k), the extraction means 26 recover this Internet address (step 320).

They will then look for the information 1 designated by this address on the database 21 and transmit it to the device 22 which displays it (steps 330 and 340).

 Although two specific embodiments have been described, they are not considered to limit the scope of the present invention.

 The information pages to be displayed can be stored on databases, whether or not integrated into the various servers used.

 They can be of different natures. For example, these can be: - registration, purchase, sale, etc. forms.

 - new products, services; - promotional products, services; - specific products, services (example: "hidden" high value-added Internet pages paid for by voice communication using an audiotel telephone number, a bank card number, etc.); - the home page of the website in a different language; - Internet pages belonging to competitors (product comparison), or partners (complementarity of products or services, etc.); - etc ...

 They may or may not belong to provider F and may be of standard type (HTTP) or of secure type (HTTPS).

 One can also imagine the implementation of the present invention in the case where the elements constituting the stations of the supplier F and the receiver R are mobile, thanks in particular to the use of UMTS technology.

 In addition, one or all of the telephones used can be "IP telephones", integrating gateways or even directly connected to the Internet network. Voice communication can be IP end-to-end, PSTN end-to-end, or mixed.

<Desc / Clms Page number 15>

 The keys of the supplier's telephone generating the control signals can be keys dedicated or not to this function.

 Finally, although the present invention has been described in the context of the Internet, this is in no way limiting since it is entirely possible to imagine the use of a display control system according to the present invention on a Ethernet network, LAN, or other.
