Description

La présente invention se rapporte à un procédé de validation instantanée d'actions dans le cadre d'émissions télévisées et à un dispositif de mise en oeuvre.The present invention relates to a method for instantaneous validation of actions in the context of television broadcasts and to an implementation device.

Le téléachat tel qu'il est pratiqué actuellement par les distributeurs de programmes télévisés, consiste généralement à présenter au cours d'une émission spécialisée divers objets et à demander aux téléspectateurs intéressés de téléphoner à un organisme de réservation, en lui communiquant, le cas échéant, leur numéro de carte bancaire.Teleshopping as it is currently practiced by distributors of television programs, generally consists of presenting various objects during a specialized program and asking interested viewers to telephone a reservation organization, communicating to it if necessary. , their bank card number.

Un tel procédé n'est pas très rapide ni fiable, du fait que les communications téléphoniques durent un temps non négligeable et peuvent donc décourager les personnes n'arrivant pas à obtenir la communication s'il y a au même moment un grand nombre d'appels, et ne permettent pas d'identifier leur origine.Such a method is not very rapid or reliable, since telephone communications last a considerable time and can therefore discourage people who are unable to obtain the communication if there is at the same time a large number of calls, and do not identify their origin.

En outre, ce procédé ne permet pas aux téléspectateurs de participer à certains jeux nécessitant une réponse instantanée ou à un instant bien déterminé. Il ne permet pas non plus de déterminer si tous les téléspectateurs ayant répondu à des questions posées au cours de cette émission ont effectivement regardé cette émission.In addition, this method does not allow viewers to participate in certain games requiring an instant response or at a specific time. It also does not make it possible to determine whether all the viewers who answered questions asked during this program actually watched this program.

La présente invention a pour objet un procédé de validation sûre et pratiquement instantanée d'une action dans le cadre d'émissions télévisées. La présente invention a en particulier pour objet un procédé de téléachat permettant à un grand nombre de téléspectateurs de commander pratiquement instantanément le ou les objets qui les intéresse(nt), et permettant aux distributeurs de programmes d'être assurés que le maximum de téléspectateurs intéressés puissent commander effectivement les objets désirés.The subject of the present invention is a method of safe and practically instantaneous validation of an action in the context of television broadcasts. The present invention particularly relates to a teleshopping process allowing a large number of viewers to order almost instantaneously the object or objects which interest them (s), and allowing program distributors to be assured that the maximum number of interested viewers can actually order the desired items.

La présente invention a également pour objet un procédé de validation d'une action, dans le cadre d'émissions télévisées, qui permette à au moins une partie des téléspectateurs de participer à des jeux ou concours en fournissant à des instants déterminés et selon des modalités déterminées, des réponses à des questions posées lors de ces émissions, et ce, de façon irréfutable, et qui permette également aux producteurs ou annonceurs de ces émissions de savoir de façon pratiquement sûre que les téléspectateurs ayant répondu aux questions posées lors d'émissions ont bien regardé ces émissions.The present invention also relates to a method for validating an action, within the framework of television broadcasts, which allows at least some of the viewers to participate in games or contests by providing at determined times and according to modalities. determined, answers to questions posed during these broadcasts, and this, in an irrefutable way, and which also allows the producers or advertisers of these broadcasts to know in an almost certain way that the viewers who answered the questions asked during broadcasts watch these shows.

La présente invention a également pour objet un dispositif de mise en oeuvre du procédé précité, dispositif simple et le plus fiable possible.The present invention also relates to a device for implementing the above method, a simple device and as reliable as possible.

Le procédé conforme à l'invention, mis en oeuvre dans un réseau de télévision dans lequel les récepteurs sont munis de lecteurs de cartes à microprocesseur, consiste à faire envoyer par l'émetteur, pendant les laps de temps où les téléspectateurs sont susceptibles de réagir aux émissions, au moins une information permettant d'authentifier à des instants déterminés la réaction des téléspectateurs intéressés, qui en réagissant, déclenchent le traitement confidentiel de cette information dans leur carte à microprocesseur, ce traitement produisant une autre information qu'ils renvoient en différé à l'émetteur.The method according to the invention, implemented in a television network in which the receivers are provided with microprocessor card readers, consists in sending by the transmitter, during the time periods when the viewers are likely to react at transmissions, at least one piece of information making it possible to authenticate at determined times the reaction of the interested viewers, who, by reacting, trigger the confidential treatment of this information in their microprocessor card, this treatment producing other information which they return deferred to the transmitter.

Selon un aspect avantageux du procédé de l'invention, les informations envoyées par l'émetteur comportent une donnée d'identification (relative à l'émission), une donnée de date, et une donnée, le cas échéant évolutive, permettant d'authentifier la réaction des téléspectateurs concernés et les téléspectateurs eux-mêmes.According to an advantageous aspect of the method of the invention, the information sent by the transmitter comprises an identification datum (relating to the emission), a datum datum, and a datum, if necessary evolving, making it possible to authenticate the reaction of the concerned viewers and the viewers themselves.

Selon l'invention, l'émetteur d'un réseau de télévision comporte des moyens produisant des données d'authentification, ces données comprenant des données d'identification de contenus d'émissions, de date et éventuellement de sélection de téléspectateurs. Dans chaque récepteur concerné du réseau, le dispositif lecteur de cartes à microprocesseur, comporte des moyens d'échange d'informations avec des cartes à microprocesseur et des moyens permettant de commander l'affichage de données élaborées par des cartes à microprocesseur coopérant avec le dispositif lecteur.According to the invention, the transmitter of a television network comprises means producing authentication data, this data comprising data identifying program content, date and possibly selection of viewers. In each concerned receiver of the network, the microprocessor card reader device, comprises means for exchanging information with microprocessor cards and means for controlling the display of data produced by microprocessor cards cooperating with the reader device.

La présente invention sera mieux comprise à la lecture de la description détaillée d'un mode de réalisation, pris à titre d'exemple non limitatif et illustré par le dessin annexé dont la figure unique est un bloc-diagramme simplifié d'un réseau de télévision conforme à l'invention.The present invention will be better understood on reading the detailed description of an embodiment, taken by way of nonlimiting example and illustrated by the appended drawing, the single figure of which is a simplified block diagram of a television network. according to the invention.

Le réseau 1 de télévision représenté sur le dessin comprend un émetteur 2 et un grand nombre de récepteurs. Un seul de ces récepteurs, référencé 3, a été représenté sur le dessin.The television network 1 shown in the drawing comprises a transmitter 2 and a large number of receivers. Only one of these receivers, referenced 3, has been shown in the drawing.

Le récepteur 3 comporte, en plus de ses dispositifs habituels, un lecteur 4 de cartes à microprocesseur. Une telle carte 5 a été représentée sur le dessin.The receiver 3 comprises, in addition to its usual devices, a reader 4 of microprocessor cards. Such a card 5 has been shown in the drawing.

L'émetteur 2 comporte un dispositif 2′ de production de données d'identification et d'authentification décrites en détail ci-dessous.The transmitter 2 includes a device 2 ′ for producing identification and authentication data described in detail below.

Tous les récepteurs du réseau 1 ne sont pas nécessairement équipés d'un lecteur de cartes à microprocesseur, mais, de préférence, la majorité en sont équipés, comme par exemple le récepteur 3. Le lecteur 4 de ce récepteur 3 comporte en plus de ses circuits habituels, un dispositif 4′ d'échange d'informations avec la carte 5 et de commande d'affichage de messages, par exemple sur l'écran du tube cathodique 3′ de ce récepteur.All the receivers of network 1 are not necessarily equipped with a microprocessor card reader, but, preferably, the majority are equipped with it, such as for example the receiver 3. The reader 4 of this receiver 3 comprises in addition to its usual circuits, a device 4 ′ for exchanging information with the card 5 and for controlling the display of messages, for example on the screen of the cathode ray tube 3 ′ of this receiver.

On va d'abord décrire le procédé permettant aux téléspectateurs, dont les récepteurs sont munis de lecteurs tels que le lecteur 4, d'effectuer des "téléachats".We will first describe the process allowing viewers, whose receivers are equipped with readers such as reader 4, to carry out "teleshopping".

Au cours d'une émission de téléachat, les animateurs de cette émission présentent un ou plusieurs articles. Lorsque la présentation d'un article est terminée, l'un des employés de la station émettrice commande la production par le dispositif 2′ d'une première information cryptée I1 = ID + D + X qui est aussitôt diffusée par la même voie que les émissions de l'émetteur 1. Dans l'expression de I1, ID est une donnée permettant d'identifier l'article proposé, et, le cas échéant, son prix et/ou des caractéristiques optionnelles (couleur, spointure, etc). D est la date courante, et, le éas échéant, l'heure courante. "X" est une donnée permettant de sélectionner une partie des téléspectateurs (pour une région déterminée, pour une catégorie socio-professionnelle déterminée...) si l'on désire que seule cette partie des téléspectateurs puisse réagir à l'émission. L'information I1 peut intégrer implicitement les composantes ID et D : elle peut être un nombre évoluant en fonction du temps selon une loi permettant de déduire un instant donné en connaissant la valeur de I1 à cet instant, et en outre, la valeur de I1 peut dépendre des articles proposés, de leur prix, etc...During a teleshopping program, the hosts of this program present one or more articles. When the presentation of an article is finished, one of the employees of the transmitting station orders the production by device 2 ′ first encrypted information I1 = ID + D + X which is immediately disseminated by the same channel as the transmissions of the transmitter 1. In the expression of I1, ID is a data allowing to identify the proposed article, and, if applicable, its price and / or optional characteristics (color, spointure, etc.). D is the current date, and, if applicable, the current time. "X" is a data allowing to select a part of the televiewers (for a given region, for a determined socio-professional category ...) if one wishes that only this part of the televiewers can react to the emission. The information I1 can implicitly integrate the components ID and D: it can be a number evolving as a function of time according to a law making it possible to deduce a given instant by knowing the value of I1 at this instant, and moreover, the value of I1 may depend on the items offered, their price, etc ...

L'information I1 coopère avec des données d'authentification de l'utilisateur du récepteur 3 mémorisées dans une section protégée de la mémoire de la carte 5 (ces données ne peuvent être ni lues ni modifiées de l'extérieur de la carte). Ces données d'authentification sont par exemple celles d'un algorithme de commande d'un processus combinatoire agissant sur l'information I1 ce processus étant unique pour chaque carte, donc permettant d'identifier le possesseur de la carte. Le résultat de la combinaison est affiché sur l'écran 3 si on appuie sur un bouton 6 du récepteur 3. Ce résultat est appelé ici "Y". Etant donné que le nombre Y a été obtenu grâce à un processus combinatoire secret, on peut estimer que ce nombre permet d'authentifier avec le maximum possible de sécurité le processus de la carte et son action.The information I1 cooperates with authentication data of the user of the receiver 3 stored in a protected section of the memory of the card 5 (these data can neither be read nor modified from outside the card). This authentication data is for example that of an algorithm for controlling a combinatorial process acting on the information I1, this process being unique for each card, therefore making it possible to identify the owner of the card. The result of the combination is displayed on the screen 3 if a button 6 of the receiver 3 is pressed. This result is here called "Y". Given that the number Y was obtained by a secret combinatorial process, it can be estimated that this number makes it possible to authenticate with the maximum possible security the process of the card and its action.

Lorsqu'un article présenté intéresse un téléspectateur, et que celui-ci veut le commander, il appuie aussitôt sur le bouton 6 du récepteur 3. L'écran 3′ affiche la valeur de Y correspondant à cet article et à l'instant de manipulation du bouton 6.When an article presented interests a viewer, and the latter wants to order it, he immediately presses button 6 of the receiver 3. The screen 3 ′ displays the value of Y corresponding to this article and the instant of manipulation button 6.

La carte 5 peut comporter un crédit (pré-payé au moment de l'achat de la carte) qui est alors débité du montant du prix de l'article commandé, ou d'une partie de ce prix. Le téléspectateur communique en différé (par la poste, par "Minitel", par téléphone ...) ou de façon immédiate s'il y a une voie de retour du récepteur 3 vers l'émetteur 2 (réseau câblé, modem ...), le nombre Y pour recevoir l'article retenu et faire débiter, le cas échéant, son compte bancaire (par exemple en communiquant le numéro de sa carte de crédit) du montant du prix de ltarticle, ou de la somme restant à payer (si une partie du prix a été débitée sur la carte 5).Card 5 may include a credit (pre-paid at the time of card purchase) which is then debited for the amount of the price of the item ordered, or part of this price. The viewer communicates on a delayed basis (by post, by "Minitel", by telephone ...) or immediately if there is a return channel from receiver 3 to transmitter 2 (cable network, modem ... ), the number Y to receive the selected item and have their bank account debited, if applicable (for example by communicating their credit card number), of the amount of the item's price, or of the amount still to be paid ( if part of the price has been charged to the card 5).

Ainsi, grâce à l'invention, tous les téléspectateurs peuvent commander instantanément l'article qui les intéresse, sans avoir à attendre qu'une ligne téléphonique de la station de l'émetteur soit libérée, et l'organisme gérant la station peut être assuré que le maximum de téléspectateurs intéressés ont passé commande des articles présentés, et que toutes les commandes qui lui parviennent sont authentiques et sérieuses.Thus, thanks to the invention, all viewers can instantly order the article which interests them, without having to wait for a telephone line from the station of the transmitter to be released, and the body managing the station can be assured that the maximum number of interested viewers have placed an order for the articles presented, and that all the orders which reach it are authentic and serious.

Le procédé de l'invention permet également d'organiser des jeux ou des sondages auxquels peuvent participer tous les téléspectateurs ayant un récepteur tel que le récepteur 3. Dans ce cas, au lieu du simple contacteur commandé par le bouton 6, on peut disposer dans le récepteur 3 un clavier d'introduction de données. L'information I1 a alors des composantes qui sont fonction des jeux et des réponses à y fournir : en plus des composantes D et ID, on peut par exemple prévoir des composantes relatives à différentes réponses de question à choix multiple. La ou les réponses produisent des nombres Y correspondants que les téléspectateurs transmettent au centre émetteur après avoir joué. Dans certains cas, pour ne pas avoir besoin d'un clavier d'introduction de données, et se contenter du bouton 6, on peut prévoir, par exemple pour des questions à choix multiple, de présenter les différentes réponses possibles à des instants différents suffisamment espacés les uns des autres pour tenir compte des temps de réaction des téléspectateurs, l'information I1 étant modifiée pour chacun de ces instants. Ainsi, différentes valeurs de I1, produisant des valeurs correspondantes et différentes de Y, correspondent à des réponses possibles différentes à la même question, dont l'une doit être validée par les téléspectateurs par manipulation du bouton 6.The method of the invention also makes it possible to organize games or surveys in which all viewers with a receiver such as receiver 3 can participate. In this case, instead of the simple contactor controlled by the button 6, it is possible to arrange in the receiver 3 a keyboard for entering data. The information I1 then has components which are a function of the games and the responses to be provided there: in addition to the components D and ID, it is possible, for example, to provide components relating to different answers to multiple choice questions. The response (s) produce corresponding Y numbers which viewers transmit to the transmitting center after playing. In some cases, so as not to need a data entry keyboard, and to be satisfied with the button 6, it is possible to provide, for example for multiple choice questions, to present the different possible answers at different times sufficiently spaced from each other to take into account the reaction times of viewers, the information I1 being modified for each of these moments. Thus, different values of I1, producing corresponding and different values of Y, correspond to different possible answers to the same question, one of which must be validated by the viewers by manipulation of the button 6.

L'information I1 est transmise, de façon connue en soi, dans les lignes inutilisées par l'image des trames vidéo émises par l'émetteur 2.The information I1 is transmitted, in a manner known per se, in the unused lines by the image of the video frames transmitted by the transmitter 2.
