Abstract

The audience rating of broadcasts from a station (1), in particular a radio station or a radio/television station, is measured by recording in memory cards (4), principally electronic chip cards, metering units broadcast parallel with and at the time of broadcasts from the station. The parallel broadcast can be a broadcast coded within the radio-frequency band used. Preferably this parallel broadcast is made using a computerised telephone communications server (16) to which the memory cards of the listeners are linked by a reader/recorder (17) connected to a modulator demodulator (18, 19) interfaced (15) with this server. It is shown that measurement of the audience rating is improved, that the quality of the information extracted from this measurement is improved, and that the listeners are spared excessive costs. <IMAGE>

Description

La présente invention a pour objet un système de mesure du taux d'écoute des émissions d'une station. Elle concerne plus particulièrement le domaine des médias où les stations de type radiophonique ou de radio télévision cherchent à connaître, pour établir leurs tarifs de publicité, l'étendue de leur auditoire.The present invention relates to a system for measuring the rate of listening to the broadcasts of a station. It relates more particularly to the field of media where radio or radio television stations seek to know, in order to establish their advertising prices, the extent of their audience.

La mesure de taux d'écoute est actuellement faite par sondage et par déduction statistique. Les différentes stations radiophoniques ou chaînes de radio-télévision établissent comparativement leurs barêmes de publicité à partir de ces mesures statistiques. En pratique ces mesures statistiques passent par une manifestation positive de l'auditoire. Par exemple, au cours d'une émission, le présentateur de l'émission demande aux auditeurs d'écrire, d'envoyer une carte postale pour participer à une loterie. Le taux d'écoute est déduit du nombre de cartes postales reçues et correspondant à l'émission en question. Les auditeurs ont intérêt à envoyer une carte postale dans la mesure où ils ont une chance de gagner un lot mais le caractére aléatoire du gain du lot est tel que de très nombreux d'auditeurs ne jugent pas utile d'envoyer une carte postale. En effet cette carte postale leur coûte un peu d'argent, et l'espérance mathématique du gain qu'ils sont susceptibles d'en retirer leur paraît insuffisante vis à vis de cette dépense. En conséquence les responsables de l'émission ne peuvent pas disposer d'une mesure statistique aussi précise qu'ils le souhaiteraient.The listening rate measurement is currently done by sampling and statistical deduction. The various radio stations or radio and television channels compare their advertising rates on the basis of these statistical measures. In practice, these statistical measures involve a positive manifestation of the audience. For example, during a program, the presenter of the program asks listeners to write, to send a postcard to participate in a lottery. The viewing rate is deducted from the number of postcards received and corresponding to the program in question. Listeners have an interest in sending a postcard as long as they have a chance of winning a prize, but the randomness of winning the prize is such that very many listeners do not consider it useful to send a postcard. Indeed, this postcard costs them a little money, and the mathematical expectation of the gain that they are likely to get from it seems to them insufficient with regard to this expense. Consequently, those responsible for the program cannot have as precise a statistical measurement as they would like.

De plus un tel procédé ne permet pas, au-delà des données brutes de comptage des cartes postales, de connaître facilement les répartitions géographiques des personnes qui constituent le public de l'émission. Dans ce but néanmoins il serait possible, éventuellement, d'utiliser les adresses que les personnes ayant envoyé les cartes postales ont reportées sur la partie gauche de leur carte. Celle-ci est en général la leur et,avec une grande probabilité, représente le lieu d'écoute. Cependant l'utilisation de ces adresses nécessite une saisie dactylographique en vue de leurs retranscriptions dans un fichier. Cette saisie est fastidieuse. Dans tous les cas la lourdeur de ce système est telle que cette saisie ne peut pas être effectuée très souvent. D'ailleurs, le procédé lui-­même souffre de sa répétition trop fréquente. En effet, au bout de quelques tentatives, le public se lasse et ne répond plus. De sorte que, même parmi l'ensemble des gens relativement aventuriers qui acceptent de se prêter à ce jeu,on ne finit à terme par ne pouvoir compter que ceux qui y sont acharnés. En définitive, ces personnes ne représentent pas nécessairement la bonne image statistique du public de l'émission et de la cible commerciale que la station souhaite présenter à ses annonceurs lors de ses démarches publicitaires.In addition, such a method does not make it possible, beyond the raw postcard count data, to easily know the geographic distributions of the people who constitute the audience of the program. For this purpose, however, it might be possible, use the addresses that the people who sent the postcards have shown on the left side of their card. This is generally theirs and, with great probability, represents the place of listening. However, the use of these addresses requires typing for the purpose of transcribing them into a file. This entry is tedious. In all cases the heaviness of this system is such that this entry cannot be carried out very often. Moreover, the process itself suffers from its too frequent repetition. Indeed, after a few attempts, the public gets tired and no longer responds. So that, even among all of the relatively adventurous people who agree to lend themselves to this game, you will ultimately end up being able to count only those who are relentless. Ultimately, these people do not necessarily represent the good statistical image of the audience for the show and the commercial target that the station wishes to present to its advertisers during its advertising efforts.

On connaît un autre système de mesure du taux d'écoute basé sur le principe de la messagerie. Par l'intermédiaire du réseau téléphonique des auditeurs peuvent interroger la station, poser des questions, ou intervenir. Ces interventions peuvent être en direct pendant les émissions concernées ou éventuellement hors antenne. Les auditeurs s'adressent à un aréopage de spécialistes que la station met à leur disposition pour permettre de résoudre des problèmes d'ordre privé ou public. Cette communication à caractère plus sérieux que la loterie n'est en fait accessible qu'à un faible nombre d'intervenants. Et la mesure statistique du taux d'écoute par le décompte du nombre de ces intervenants n'est pas bien réaliste. Le système de messagerie ainsi présenté est verbal : un auditeur a alors affaire à un interlocuteur en personne. La messagerie peut être aussi écrite : les questions et/ou les réponses peuvent être échangées par un réseau téléphonique de type Minitel. Dans ce cas le nombre des intervenants peut être plus important. Ce nombre n'est par contre représentatif que des auditeurs qui souhaitent intervenir. Il ne prend pas en compte le nombre beaucoup plus important des auditeurs qui ne font qu'écouter. En principe, la fonction de messagerie est découplée d'une fonction loterie :les auditeurs qui utilisent la messagerie ne se voient pas proposer des chances de gagner des lots.Another system for measuring the listening rate is known, based on the principle of messaging. Via the telephone network, listeners can interrogate the station, ask questions, or intervene. These interventions can be live during the relevant programs or possibly off the air. The listeners turn to a group of specialists that the station places at their disposal to help solve problems of a private or public nature. This communication, more serious than the lottery, is in fact only accessible to a small number of participants. And the statistical measurement of the listening rate by counting the number of these speakers is not very realistic. The messaging system thus presented is verbal: an auditor then deals with an interlocutor in person. Messaging can also be written: questions and / or answers can be exchanged over a Minitel telephone network. In this case the number of speakers may be greater. However, this number is only representative of listeners who wish to intervene. It does not take into account the much larger number of listeners who only listen. In principle, the messaging function is decoupled from a lottery function: auditors who use messaging are not offered chances to win prizes.

L'invention a pour objet de remédier à ces inconvénients et de proposer un système qui permet d'approcher plus finement, avec une statistique plus précise,le nombre des auditeurs des émissions. Le système de l'invention repose dans son principe sur l'émission, à l'initiative de la station, d'informations codées. Les personnes qui constituent le public de la station en question se voient en outre attribuer des cartes à mémoire principalement du type cartes à "puce" électroniques ou magnétiques dans lesquelles les informations codées émises à l'occasion des émissions de ces stations sont destinées à être enregistrées. Cette opération ne coûte rien aux auditeurs. Par une manipulation simple un auditeur peut provoquer le téléchargement de ces informations codées dans sa carte et ultérieurement, éventuellement périodiquement, il peut envoyer sa carte à la station. Cette station lui attribue en crédit dont le montant est proportionnel au nombre d'informations codées enregistrées et, en quelque sorte, à la fidélité qu'il a manifestée à cette station. En quelque sorte ce mode de mesure constitue une loterie où on gagne à coup sûr, un peu, mais suffisamment pour être bien payé du geste de validation de l'enregistrement des informations codées. Les cartes à "puce" récupérées peuvent comporter, dans les informations codées et enregistrées, la spécificité des émissions qui ont été particulièrement suivies ainsi que, par la connaissance de l'adresse de l'auditeur également enregistrée dans la carte, la répartition géographique des pôles d'intérêt. Le système proposé présente donc les avantages attendus d'être plus proche de la réalité quant au nombre d'auditeurs touchés, d'indiquer la répartition géographique de ces auditeurs sur le territoire et, par ailleurs, de permettre la répétition fréquente du sondage de manière à tester toutes les émissions de la station sans risquer de lasser ces auditeurs.The object of the invention is to remedy these drawbacks and to propose a system which makes it possible to approach more finely, with more precise statistics, the number of listeners of the broadcasts. The system of the invention is based in principle on the transmission, on the initiative of the station, of coded information. The persons who constitute the public of the station in question are furthermore allocated memory cards mainly of the electronic or magnetic "chip" type in which the coded information transmitted during the transmissions of these stations is intended to be saved. This operation costs the listeners nothing. By a simple manipulation a listener can cause the downloading of this coded information in his card and later, possibly periodically, he can send his card to the station. This station gives him credit, the amount of which is proportional to the number of coded information recorded and, in a way, to the loyalty he has shown to this station. In a way, this method of measurement constitutes a lottery where one wins for sure, a little, but enough to be well paid for the gesture of validation of the recording of coded information. The "smart" cards recovered may include, in the coded and recorded information, the specificity of the emissions which have been particularly monitored as well as, by knowing the address of the auditor also recorded in the map, the geographic distribution of the areas of interest. The proposed system therefore has the expected advantages of being closer to reality as regards the number of listeners affected, of indicating the geographic distribution of these listeners on the territory and, moreover, of allowing frequent repetition of the survey so to test all the station's programs without risking boring these listeners.

L'invention a en conséquence pour objet un système de mesure du taux d'écoute des émissions d'une station, notamment d'une station radiophonique ou d'une station de radio-télévision caractérisé en ce qu'il comporte :
- des cartes à mémoire distribuées à des personnes composant le public de cette station,
- et des lecteurs-enregistreurs de cartes à mémoire à la disposition de ces personnes pour enregistrer dans ces cartes des informations codées émises à l'occasion des émissions de cette station. De manière préférée les cartes à mémoire contiennent des circuits, ou des "puces", électroniques.The subject of the invention is therefore a system for measuring the listening rate of the broadcasts of a station, in particular a radio station or a radio-television station, characterized in that it comprises:
- memory cards distributed to people making up the public at this station,
- and memory card readers and recorders available to these people to record in these cards coded information transmitted during the transmissions of this station. Preferably the memory cards contain electronic circuits, or "chips".

L'invention sera mieux comprise à la lecture de la description qui suit et à l'examen des figures qui l'accompagnent. Celles-ci ne sont données qu'à titre indicatif et nullement limitatif de l'invention. Les figures montrent :

  • - figure 1 : une variante hertzienne de mise en oeuvre du système de mesure de l'invention;
  • - figure 2 : une variante préférée de l'invention où la transmission des informations codées est effectuée par voie téléphonique.
The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are given for information only and in no way limit the invention. The figures show:
  • - Figure 1: a hertzian variant of implementation of the measurement system of the invention;
  • - Figure 2: a preferred variant of the invention where the transmission of coded information is carried out by telephone.

La figure 1 montre un système de mesure du taux d'écoute conforme à l'invention. Une station 1 émet par rayonnement radio ou par faisceaux hertziens une émission 2 à destination de poste récepteurs 3 appartenant à des personnes qui constituent le public de la station 1. Chaque auditeur ou téléspectateur est muni d'une carte à mémoire, ou carte à "puce", 4 spécialisée, et destinée à être introduite dans un lecteur-enregistreur 5 de cartes à mémoire. Le lecteur-enregistreur 5 est prévu pour enregistrer dans les cartes des informations codées émises à l'occasion d'émissions de cette station. Dans un exemple les informations codées comportent des informations logiques, des séries de 0 et de 1, émises sous forme impulsionnelle dans la bande même de fréquence de l'émission. De manière préférée, le système, dans sa version hertzienne, comporte un décodeur 6 couplé au récepteur 3 pour effectuer un décodage automatique des émissions de la station et pour permettre l'enregistrement des informations codées. Dans la pratique un des deux dispositifs,le lecteur-enregistreur 5 ou le décodeur 6, ou même les deux peuvent être couplés fonctionnellement au récepteur 3 pour n'être en service que lorsque ce récepteur 3 est lui-même en fonctionnement : c'est à dire lorsque l'auditeur écoute effectivement les émissions de la station.FIG. 1 shows a system for measuring the listening rate according to the invention. A station 1 transmits by radio radiation or by radio beams a program 2 intended for receiving stations 3 belonging to persons who constitute the public of the station 1. Each listener or viewer is provided with a memory card, or "chip" card, 4 specialized, and intended to be introduced into a reader-recorder 5 of memory cards. The reader-recorder 5 is designed to record in the cards coded information transmitted on the occasion of transmissions from this station. In one example, the coded information includes logical information, series of 0 and 1, transmitted in pulse form in the same frequency band of the transmission. Preferably, the system, in its hertzian version, comprises a decoder 6 coupled to the receiver 3 to carry out an automatic decoding of the transmissions of the station and to allow the recording of the coded information. In practice one of the two devices, the reader-recorder 5 or the decoder 6, or even both can be functionally coupled to the receiver 3 so as to be in service only when this receiver 3 is itself in operation: this is when the listener actually listens to the station's broadcasts.

De manière à simplifier les procédures de mise en service du décodeur 6 l'emission peut comporter, préalablement à l'envoi des informations codées, la diffusion d'un indicatif caractéristique des informations codées qui le suivent. Cet indicatif peut être musical et comporter une suite de notes aisément reconnaissables. Un détecteur d'indicatif 7 peut alors provoquer la mise en service automatique du décodeur 6. Cependant, pour éviter dans ce cas que les auditeurs laissent branché leur récepteur même pendant leur absence, il est prévu, en série dans la transmission des informations codées du récepteur 3 au lecteur-enregistreur 5, un dispositif de validation manuelle. Ce dispositif de validation comporte un bouton 9 de validation manuelle de la transmission. Le moment venu l'auditeur valide l'enregistrement des informations codées. La carte à mémoire 4 peut comporter plusieurs zones mémoire, par exemple 10 à 13, pour contenir des informations relatives d'une part à l'identité, ou au moins au lieu de résidence, de l'auditeur, et d'autre part aux informations codées successivement enregistrées. Au bout d'une certaine durée, par exemple tous les mois, l'auditeur envoie sa carte à la station et celle-ci la lui retourne quelques temps après assortie d'une récompense proportionnelle au nombre d'informations codées qui y sont enregistrées.In order to simplify the procedures for bringing the decoder 6 into service, the transmission may include, before sending the coded information, the dissemination of an indicative characteristic of the coded information which follows it. This code may be musical and include a series of easily recognizable notes. A code detector 7 can then cause the automatic decoder 6 to be put into service automatically. However, in order to avoid in this case that the listeners leave their receiver connected even during their absence, provision is made in series for the transmission of coded information from the receiver 3 to reader-recorder 5, a validation device manual. This validation device includes a button 9 for manual validation of the transmission. When the time comes, the auditor validates the recording of the coded information. The memory card 4 can comprise several memory zones, for example 10 to 13, to contain information relating on the one hand to the identity, or at least to the place of residence, of the listener, and on the other hand to the successively recorded coded information. At the end of a certain period, for example every month, the listener sends his card to the station and the station returns it to him some time after, accompanied by a reward proportional to the number of coded information items stored there.

La figure 2 montre une variante préférée de réalisation du système de l'invention. Dans celle-ci la fiabilité de l'exécution de l'enregistrement des informations codées dans les cartes est mieux assurée. Surtout dans cette variation la mesure du taux d'écoute est faite quasiment en temps réel. Dans ce système une station 1 émet également des émissions 2 à destination de postes récepteurs 3 appartenant à ces auditeurs. Ceux-ci sont également munis de cartes à mémoire 4. Mais la transmission des informations codées n'est pas faite en parallèle sur la bande de fréquence de l'émission 2 par voie hertzienne. Elle est faite par un réseau téléphonique. Les auditeurs possèdent dans ce but un terminal 14 de liaison à un réseau téléphonique télématique 15 géré par un organisme public ou privé de communications téléphoniques. La station 1 gère par ailleurs un serveur 16 susceptible d'intervenir sur le réseau 15. La mesure du taux d'écoute se pratique de la manière suivante. A un moment particulier d'une émission dont on veut mesurer le taux d'écoute, on émet un indicatif caractéristique de l'imminence de l'émission des informations codées à enregistrer. Les auditeurs qui écoutent introduisent alors leur carte à mémoire 4 dans un lecteur enregistreur 17 de cartes à mémoire relié fonctionnellement à leur poste téléphonique 18 et au réseau télématique 15. Cette liaison fonctionnelle est obtenue soit directement, soit par l'intermédiaire d'un modem contenu dans une console d'échange 19 de type Minitel. Les dispositifs 17, 18 et 19 appartiennent au terminal 14. Ayant introduit leur carte 4, ils cherchent ensuite à se mettre en relation avec le serveur 16. Dans ce but ils composent simplement avec le cadran 20 du poste 18 le numéro du canal du réseau 15 auquel ils veulent être raccordés. Une fois raccordés, avec des boutons de programmation 21 de la console 19 ils composent le code du serveur 16. Dès que ces opérations sont terminées, le réseau 15 met le terminal 14 en liaison avec le serveur 16. Le serveur 16 peut alors envoyer des instructions aux lecteurs-enregistreurs de cartes à mémoire 17 pour qu'ils enregistrent dans les cartes à mémoire introduites les informations codées. Ces informations codées sont envoyées par le serveur lui-même.FIG. 2 shows a preferred variant embodiment of the system of the invention. In this the reliability of the execution of the recording of the information coded in the cards is better ensured. Especially in this variation the measurement of the listening rate is made almost in real time. In this system, a station 1 also transmits transmissions 2 to receiving stations 3 belonging to these listeners. These are also provided with memory cards 4. However, the transmission of the coded information is not carried out in parallel on the frequency band of transmission 2 by radio. It is done by a telephone network. The auditors have for this purpose a terminal 14 for connection to a telematic telephone network 15 managed by a public or private body for telephone communications. The station 1 also manages a server 16 capable of intervening on the network 15. The measurement of the listening rate is carried out in the following manner. At a particular moment of a program for which the listening rate is to be measured, an indicative characteristic of the imminence of the transmission of the coded information to be recorded is emitted. Listeners who listen then insert their memory card 4 into a reader recorder 17 of memory cards functionally connected to their telephone set 18 and to the telematic network 15. This functional link is obtained either directly or by means of a modem contained in an exchange console 19 of the Minitel type. The devices 17, 18 and 19 belong to the terminal 14. Having introduced their card 4, they then seek to get in touch with the server 16. For this purpose they simply dial the number of the network channel with the dial 20 of the station 18 15 to which they want to be connected. Once connected, with programming buttons 21 of the console 19 they compose the code of the server 16. As soon as these operations are completed, the network 15 puts the terminal 14 in connection with the server 16. The server 16 can then send instructions to memory card reader-recorders 17 so that they record the coded information in the memory cards inserted. This coded information is sent by the server itself.

Ce type de fonctionnement appelle deux remarques. Premièrement la liaison par voie téléphonique n'est pas gratuite :des taxes sont perçues au profit d'organismes qui gèrent le réseau de communications téléphoniques et au profit du serveur. On peut admettre que le serveur va faire le cadeau en retour des taxes perçues à son profit puisque le serveur dépend de la station. Cependant l'organisme qui gère les communications téléphoniques n'a aucune raison de l'accepter. En conséquence la récompense à laquelle doit avoir droit l'auditeur doit être supérieure au coût de cette quote part. Deuxièmement cet effet gênant a cependant un avantage : la quote part remboursée par la station peut être forfaitaire. Ceci incite les auditeurs à couper leur liaison avec le serveur 16 dès que les informations codées ont été transmises. Les auditeurs sont ainsi incités à couper leur liaison téléphonique sans attendre, et payer pendant une durée trop longue, que de nouvelles informations codées soit réémises par le serveur. Ceci permet d'éviter que les auditeurs ne laissent leur poste téléphonique branché. Ce branchement permanent fausserait la mesure statistique et risquerait de coûter cher à la station. En outre en agissant ainsi ces auditeurs neutraliseraient trop longtemps leur poste téléphonique.This type of operation calls for two remarks. First, the link by telephone is not free: taxes are collected for the benefit of organizations that manage the telephone communications network and for the benefit of the server. We can assume that the server will give the gift in return for the taxes collected for its benefit since the server depends on the station. However, the organization that manages telephone communications has no reason to accept it. Consequently, the reward to which the auditor must be entitled must be greater than the cost of this quota share. Secondly, this annoying effect has an advantage, however: the share reimbursed by the station can be a flat rate. This encourages listeners to cut their connection to the server 16 as soon as the coded information has been transmitted. Listeners are thus encouraged to cut their telephone connection without delay, and pay for too long a period, that new coded information is retransmitted by the server. This is to prevent listeners from leaving their telephone set plugged in. This permanent connection would distort the statistical measurement and risk costing the station dearly. Furthermore, by doing so, these listeners would neutralize their telephone set for too long.

Pour simplifier l'opération de distribution des récompenses, les informations codées peuvent représenter tout simplement des unités de compte d'un crédit de paiement. Dans ce cas la carte à mémoire 4 doit pouvoir contenir en plus un micro-processeur 22 pour additionner au fur et à mesure de leur édition les unités de compte envoyées par le serveur. Des commerçants sous contrat avec la station 12 peuvent alors accepter de rétribuer l'auditeur au prorata du nombre d'unités de compte que la carte 4 qu'il leur présente contient. La notion d'unité de compte revêtant une quantité d'information faible, on comprend que ce procédé plus rustique peut ne pas permettre de savoir quels types d'émissions particulières ont intéressé les auditeurs. En effet on a cumulé les unités de compte quelle que soit la nature de l'émission radiophonique au cours de laquelle elles ont été émises. Cependant, en utilisant la répartition précitée des zones de mémoire de la carte à mémoire, et en programmant le serveur 16 à cet effet, on peut provoquer l'accumulation des unités de compte, acquises au cours d'émission de type différent, dans des zones différentes de la mémoire.To simplify the operation of distributing the rewards, the coded information can quite simply represent units of account of a payment credit. In this case the memory card 4 must be able to additionally contain a microprocessor 22 to add, as and when they are edited, the units of account sent by the server. Merchants under contract with station 12 can then agree to remunerate the listener in proportion to the number of account units that the card 4 that he presents to them. The concept of unit of account taking up a small quantity of information, it is understood that this more rustic process can not make it possible to know which types of particular emissions interested the listeners. In fact, the units of account have been cumulated whatever the nature of the radio program during which they were transmitted. However, by using the aforementioned distribution of the memory areas of the smart card, and by programming the server 16 for this purpose, it is possible to cause the accumulation of the units of account, acquired during transmission of different type, in different areas of memory.

La carte 4 peut, en plus de la comptabilité des unités de compte, comporter un code personnalisé 23 qui peut être réémis par le lecteur-enregistreur 17 sur le réseau 15 quand une communication avec le serveur 16 est établie. Dans ces conditions le serveur 16 peut alors effectuer un tirage au sort de ces codes personnalisés et attribuer à un de ces auditeurs choisi par hasard un cadeau plus substantiel que la récompense de base. Le système de l'invention permet donc également le fonctionnement en loterie. De manière à récompenser préférentiellement les bons auditeurs, ou au moins ceux qui acceptent régulièrement de participer à la mesure du taux d'écoute, le micro-processeur 22 peut également être programmé pour n'envoyer le code 23 que si le nombre d'unités de compte stockées dans la carte 24 est suffisant : s'il dépasse un seuil fixé par avance, par exemple.The card 4 can, in addition to the accounting of the units of account, include a personalized code 23 which can be re-issued by the reader-recorder 17 on the network 15 when a communication with the server 16 is established. Under these conditions, the server 16 can then draw lots for these personalized codes and assign a gift to one of these listeners. more substantial than the basic reward. The system of the invention therefore also allows operation in the lottery. In order to preferentially reward good listeners, or at least those who regularly agree to participate in the measurement of the listening rate, the microprocessor 22 can also be programmed to send the code 23 only if the number of units account stored in card 24 is sufficient: if it exceeds a threshold set in advance, for example.

Pour simplifier les relevés statistiques, le serveur 16 comporte d'une manière connue des moyens pour mesurer quand, combien, et à qui il a envoyé des informations codées. L'information quand renseigne sur le type de l'émission pour laquelle le sondage a été fait. L'information combien mesure directement le taux d'écoute. L'information à qui, déduite de la répartition géographique des auditeurs qui est connue du serveur, par exemple par l'envoi d'un code personnalisé du même type que le code 23 ou par l'envoi par l'auditeur d'un mot de passe propre à l'auditeur, permet d'affiner la connaissance de la station sur son public. Cette procédure permet d'éviter l'envoi régulier par les auditeurs de leur carte à mémoire à la station 1 pour que les informations qu'elle contient soit dépouillées.To simplify the statistical reports, the server 16 comprises, in a known manner, means for measuring when, how much, and to whom it has sent coded information. The information when provides information on the type of program for which the survey was conducted. The information how much directly measures the listening rate. Information to whom, deduced from the geographic distribution of listeners that is known to the server, for example by sending a personalized code of the same type as code 23 or by sending a word to the auditor pass specific to the listener, allows to refine the knowledge of the station on its public. This procedure makes it possible to avoid the regular sending by the listeners of their memory card to station 1 so that the information it contains is analyzed.

En outre, la partition de la mémoire de la carte à mémoire 4 peut permettre de distribuer des cadeaux offerts par un annonceur publicitaire particulier. Par exemple à la suite de la présentation d'un message de réclame, l'indicatif caractéristique peut être émis et, au moment où le serveur 16 est en relation avec le terminal 14, une question concernant l'annonceur peut être posée. En cas de bonne réponse émanant de l'auditeur, le serveur 16 sait lui envoyer une information codée sanctionnant son intérêt pour les produits présentés dans l'annonce publicitaire. Ce procédé permet de mesurer statistiquement et avec fiabilité l'impact d'un message publicitaire. Cette information codée correspond ainsi à un cadeau payé par l'annonceur. Pour les annonces plus simples, il peut ne pas être nécessaire de répondre à une question. Dans ce cas l'annonceur peut prendre la décision de récompenser ceux qui se connectent au serveur 16 après l'indicatif qui a suivi l'envoi de son annonce publicitaire. Ce procédé permet de mesurer statistiquement et avec fiabilité l'impact d'un message publicitaire.In addition, the partition of the memory of the memory card 4 can make it possible to distribute gifts offered by a particular advertiser. For example following the presentation of an advertisement message, the characteristic code can be sent and, when the server 16 is in contact with the terminal 14, a question concerning the advertiser can be asked. In the event of a good response from the listener, the server 16 can send him coded information confirming his interest in the products presented in the advertisement. This method makes it possible to measure statistically and reliably the impact of an advertisement. This coded information thus corresponds to a gift paid by the advertiser. For simpler announcements, it may not be necessary to answer a question. In this case, the advertiser can take the decision to reward those who connect to the server 16 after the code that followed the sending of their advertisement. This process makes it possible to statistically and reliably measure the impact of an advertising message.

Lorsque la quantité d'informations contenues dans les cartes, et accumulées petit à petit, a été exploitée, soit par la station à qui les cartes ont été renvoyées par la poste ou par le réseau télématique de la variante préférée, soit par des commerçants ou des annonceurs qui se sont associés à la station 1 et qui utilisent les unités de compte comme moyens de paiement, il est nécessaire d'effacer les mémoires de la carte à mémoire 4. Cet effacement peut être pratiqué de multiples manières. Dans la variante de la figure 2 cet effacement peut être provoqué par le serveur 16 dès qu'il a prélevé toutes les informations utiles contenues dans les cartes et qu'il les a par exemple échangées contre des unités de compte.When the quantity of information contained in the cards, and accumulated little by little, has been exploited, either by the station to which the cards were returned by post or by the telematic network of the preferred variant, or by merchants or advertisers who have associated themselves with station 1 and who use the units of account as means of payment, it is necessary to erase the memories of the memory card 4. This erasing can be practiced in many ways. In the variant of FIG. 2, this erasure can be caused by the server 16 as soon as it has taken all the useful information contained in the cards and has, for example, exchanged them for units of account.
