Definitions
- Digital and voice data transmission system connected to a telephone set and configured by smart cards
- the invention relates to a system for exchanging handwritten messages by a telecommunications network, composed of a plurality of communicating slates each making it possible to prepare, transmit to a remote slate, receive, view and manage data of text or graphics such as diagrams or drawings generated by hand using a stylus on the communicating slate, possibly during a telephone conversation, as well as a multitude of other additional applications.
- the prior document PCT 97/0097 already describes a communicating slate comprising a touch screen addressable pixel by pixel under the effect of the pressure of a stylus, a microprocessor capable of managing data associated with ROM and RAM memories, said stylus allowing create messages intended to be transmitted by the carrier current for local use and by the telephone network for use between distant slates, and this via a suitable modem.
- This complex device uses a combination of carrier current and telephone lines and has a fixed functionality by design because it is not open to various applications, which makes it rather suitable for professional uses. Furthermore, it does not describe the functionality consisting in the real-time exchange of handwritten messages while continuing a telephone communication.
- the use of the Internet allows communication between people to exchange messages or data, but requires the acquisition of a computer, with the associated disadvantages of high cost, complexity of use and rapid obsolescence, and unsuitable implementation times to meet the need to simply exchange handwritten messages.
- the object of the invention is therefore to remedy the aforementioned drawbacks.
- the subject of the invention is a data transmission system comprising a first device consisting of a telephone set and a communicating slate (2), both connected to the telephone network, and a second device also consisting a telephone set and a communicating slate, the said communicating slates being of the touch screen type addressable by a stylus, the said system comprising multiplexing means for the simultaneous transmission of the voice signals supplied by the telephone set and of the data supplied by the communicating slate, characterized in that each slate is of reduced format of the "passport" type and includes:
- the smart card reader being capable of receiving a multitude of smart cards each being dedicated to a specific application, - and in that each smart card is programmed to exchange data with the smart card reader and allow configuration of the touch screen corresponding to the specific application dedicated to it, the updating of the programming software for each of the smart cards can be by downloading via the telephone network or the Internet.
- the invention has the advantage that it allows people, whatever the distance between them, to exchange handwritten messages in deferred time, or to work in real time on the same handwritten content during a telephone communication. It allows in particular two interlocutors during telephone communication each equipped with a communicating slate according to the invention to prepare and modify together a handwritten text or graphic.
- the use of smart cards allows the establishment of communications dedicated to specific applications and constantly modifiable possibly by downloading, between electronic slates on telephone lines, these communications being able to take place by a simultaneous transmission of the transmitted data. by the electronic slates and the speech emitted by a telephone handset.
- Figure 1 a communicating slate according to the invention associated with a telephone set, both being connected to the telephone network.
- FIG. 3 a module architecture according to the invention allowing the simultaneous transmission of data and voice.
- a communicating slate according to the invention, this is in the form of a small box (1), in “passport” format, a few millimeters thick, intended to be placed next to from any telephone set and connects to it preferably by means of a pull-out socket, like a computer modem.
- the communicating slate is integrated directly into a telephone set.
- the screen (2) of the communicating slate allows virtual keys to be displayed, which makes it possible to minimize the number of physical keys in order to reduce manufacturing costs and optimize its useful surface. These virtual keys can optionally be configurable as a function of choices made by the user or as a function of a smart card inserted.
- the flat box (1) integrates on one side a graphic touch screen (2) capable of being addressed at the level of the elementary pixels by means of any stylus.
- the screen of the communicating slate is produced according to one of the techniques known from the state of the art making it possible to cause, under the effect of the pressure of a stylus, the stimulation and the addressing of the pixels on the screen (2) of the communicating slate.
- the set of coordinates (x, y) of the pixels addressed by pressing the stylus is stored in a RAM memory (5) integrated in the invention and displayed on the screen communicating slate in real time.
- the electronics of the slate consists essentially of a microprocessor (3) managing a set of memories ROM (4), RAM (5), a screen (2) and the communication of the data by the telephone network (6) via the modem (7) possibly simultaneously with the voice.
- Said software can be stored as needed, either in the RAM memory (5) or in plug-in memory modules (14).
- a set of plug-in modules can significantly increase the memory capacity of the invention or can store software corresponding to heavier applications from a smart card inserted in a smart card reader (17).
- a SIM card can be added to the microprocessor, abbreviation of the English term "Subscriber Identification Module", not shown, to allow, as is done for cellular communication networks of the GSM type, for example, remote identification of the slate. communicating or its owner.
- Each smart card has the ability to define a new slate functionality.
- Such a smart card can carry out security operations, such as the restriction of access, such another card will memorize the coordinates of the usual correspondents, such another will allow to play the lotto or a lottery.
- software stored in said card will configure the screen (2) of the communicating slate to display the elements or images making it possible to play said games.
- Other cards will allow authentication or identification, the latter cards possibly being used in combination with a confidential code entered either on the telephone keypad or on a keyboard appearing on the screen of the communicating slate.
- a dedicated memory card is allocated to a single user.
- the introduction of said card in the reader invites the user to trace his signature on the screen of the communicating slate and to enter a confidential code previously chosen.
- the correspondence between the card reference, associated with the bearer's name, and the code entered authorizes the transmission of the previously drawn signature.
- other information may also be transmitted, the analysis of which will allow the recipient to have additional authentication elements, for example by correlation between the name and said information.
- a single database can also act as a trusted third party, the allocation of cards being the subject of a procedure making it possible to guarantee the identity of the holder.
- the use of the SIM card may on this point enhance the security of transactions.
- One of the functionalities of the invention allows two distant interlocutors to simultaneously speak on the telephone and exchange graphics, or create a common graphic, by means of their communicating slates. Everything then happens as if the two distant interlocutors were side by side writing on the same communicating slate.
- This feature represents a new revolution in the world of consumer communications.
- the first technique consists in exploiting the presence of silences intervening during any conversation. It has been shown that the share of silences during any telephone conversation generally represents more than fifty percent of the total duration of the call. It is possible to use these rests to transmit the coordinates (x, y) of the pixels addressed by a stylus and memorized in RAM (5) from a slate to the distant slate.
- rests for data transmission can be achieved for example as follows: knowing that in a very large majority of cases (more than 90%) a silence lasts more than 200 milliseconds, the microprocessor of a communicating slate having new addressed pixels to transmit will reserve 150 milliseconds for data transmission each time it detects a silence exceeding 50 milliseconds. During the 150 milliseconds reserved for data transmission, voice transmission is cut in both directions of communication.
- the logic circuit ensuring the data voice multiplexing is represented in FIG. 1.
- any detection of silence, of the voice and of listening, greater than 50 milliseconds cuts the transmission of the voice by a two-position switch (8) and actuates a monostable (9) whose "timer" is programmed at 150 milliseconds, the so-called monostable actuates a door (10) for 150 milliseconds at each aforementioned silence, allowing the data stored in RAM (5) to be transferred via the modem ( 7) to the telephone network (6). This operation is repeated as long as there is silence and data is to be transmitted. At the end of a period of 150 milliseconds reserved for the data and in the absence of additional data to be transmitted, the switch (8) re-establishes the phonic link.
- the receiving slate On receiving a signal from the remote slate characteristic of the start of data transmission, the receiving slate cuts the speech for 150 milliseconds and receives the data. Such a procedure will allow in a simple manner to carry out an almost simultaneous transmission of the voice and the data without affecting the quality of voice communication, or by possibly affecting it marginally in the case of very long distance communications.
- the microprocessor will wait for the next 50 milliseconds of silence to transmit a concealment command signal for a duration of 150 milliseconds of the listening level and of the voice for the two interlocutors, signal followed by the data to be transmitted.
- the coordinates (x-y) received by the remote slate are then stored in its RAM memory. Only the new pairs (x, y) sent by the stylus, and stored in the RAM memory (5), will be transmitted.
- the average bitrate to be transmitted reaches around 2.4 Kbits / s.
- the time that can be allocated to this transmission consisting of periods of 150 milliseconds that can cover up to 37% of the total time (50% x 150ms / 200ms)
- the need for bit rate during a data transmission period is 6.4Kbits / s.
- Such a flow is widely compatible with the state of the art which today allows transmission of up to 56Kbits / s in a conventional 3KHz telephone band.
- the second simple technique presented consists in reserving part of the bandwidth from transmission to data transfer.
- Data transfer can for example be provided at one of the high or low ends of the bandwidth.
- the small amount of data to be transmitted per unit of time makes it possible to cut only a small part of the total bandwidth, which induces a marginal deterioration in the quality of voice communication.
- a filter is provided which greatly attenuates, for example by 20 decibels, the voice and listening located in this part of the bandwidth lying above 3KHz, this high part of the bandwidth being devoted to data transmission.
- the level and cutoff frequency of said attenuation can be adjusted according to the effective quality of the communication.
- a procedure will make it possible to define the cut-off frequency of the filter in the band.
- a continuous series or discontinuous frequency is sent with the characteristic signal defined above by the slate which transmits first, said frequency series covering part of the passband in the treble, for example above 2.5 kHz and up to 3.4 kHz.
- the slate microprocessor (3) which receives said characteristic signal and the associated frequency series will determine the cutoff frequency where the reception level of said signal attenuates by 10 dB for example.
- the same procedure is performed reciprocally, the quality of the transmission not always being symmetrical.
- Each of the slates having thus determined the optimum cutoff threshold of the audio tape will communicate to the other said cutoff threshold during the initial protocol.
- All the means presented in this description can be transposed into an integrated version in a fixed telephone set incorporating a communicating slate permanently visible or removable or even protected by a shutter.
- the invention can be perfectly integrated into a mobile phone, or into an accessory for a mobile phone, using the GSM network, a satellite network or equivalent or even more locally using the “DECT” standard, the so-called portable then having a slate communicating providing the functions described above.
- the device can connect to any type of network and in particular to the Internet, via a computer or not. To do this, the invention will have connectors for parallel and / or serial links and / or USB.
- connection via a computer can make it possible to ensure the function of authorizing payments by bank card using the bank card reader to pay for various purchases, or even to affix one's signature accompanied by the identification elements at the bottom of a contract displayed on the screen of said computer and intended to be sent to a contracting party.
- a plug-in memory module (14) integrating the connection procedure on said network, stores the addresses usually used in order to obtain a quick connection to suitable sites.
- This module also incorporates analog / digital voice conversion software. Such a configuration will make it possible to exchange messages of considerable size, appearing both in handwritten forms on the communicating slates and voice on the corresponding connected telephones, and this for the cost of a local communication.
- the invention makes it possible to place on the general public market a new product at very low cost, of the order of that of a simple telephone set, a real “Post-it” “registered trademark” electronic, allowing:
- the duration required is very short, typically less than the duration corresponding to the basic charging of a telecommunications operator.
- the invention therefore makes it possible to send a message of the handwritten mail type instantly, and this to the end of the world, for the cost of a local communication, or, more generally, for the cost of a communication whose duration is only a few seconds.
- each smart card can reconfigure the invention for a new application.
- said invention can be infinitely declined both for applications already identified to date and for other applications still to be imagined.
- the invention can also receive software or data by the conventional way of downloading to RAM memory from a dedicated server.
- the smart card can also provide security functions, for example authentication functions or authorization functions such as:
- authorization to send a message to a given number authorization to display received messages on the slate.
- the card's security functions can be reinforced by the combination of the presence of the card and the entry of a confidential code either on the keypad of the telephone associated with the invention, or on a numeric or alphanumeric keyboard depicted on the communicating slate thanks to software integrated or stored in the smart card.
- the level of security reached can be of a good level if one uses smart cards integrating a microprocessor managing a set of own memories such as EPROM EEPROM, said microprocessor being programmed to cooperate with the microprocessor of the invention.
- the level of security is further increased by the simultaneous use with that of the smart card of a SIM card which allows remote identification of the communicating slate.
- the latter feature has the advantage that it allows personalized exchanges between information distribution groups such as large commercial areas, banks, insurance companies, etc. and their customers.
- the communicating slate of each customer identified by the number of their SIM card can receive the list of winners, and each winner can communicate with the large area to receive their prizes.
- usage of the SIM card can allow the identification and connection of winning players in horse racing with the body responsible for these races.
- the smart card also makes it possible to ensure a multitude of applications, for example: providing standard greeting formulas intended to be transmitted to distant slates,
- . provide useful data such as the contact details of merchants participating in a promotional operation,. to play public games such as the lotto, the trike, the tic-tac-toe, chess, the game of checkers, the "game boy", the games with scratching of boxes etc.
- the introduction of '' a dedicated card, for example prepaid shows the traditional lotto grid by means of which the player is invited to tick boxes using the stylus, the player's choices are then automatically transmitted to a server center whose number is stored in the smart card, the value thereof being decremented by the amount corresponding to the game.
- the areas to be scratched appear on the screen of the touch slate, the action of the stylus on these revealing virtually hidden information, making it possible to carry out surveys among the general public, the latter being invited to answer the questions appearing on the screen of the communicating slate following the introduction of the smart card, allow mul multiple promotional operations, the card serving as a medium for the dissemination of advertisements or various games.
- allow a group of patients to be followed in a hospital environment allow information to be collected by means of an interactive questionnaire distributed to a sample of the population testing a new drug or a new molecule, enable quality procedures to be applied in the field, also through an interactive questionnaire.
