PROCEDE DE MESURE D'AUDIENCE D'APPLICATIONS INTERACTIVES METHOD FOR MEASURING AUDIENCE OF INTERACTIVE APPLICATIONS
TELEDIFFUSEES OU EMBARQUEESBROADCASTED OR ON BOARD
SUR UN DECODEUR DE RECEPTEUR DE TELEVISIONON A TELEVISION RECEIVER DECODER
L'invention concerne un procédé de mesure d'audience d'applications interactives, télédiffusées ou embarquées sur un décodeur de récepteur de télévision ou un enregistreur vidéo.The invention relates to a method for measuring the audience of interactive, broadcast or embedded applications on a television receiver decoder or a video recorder.
D'une manière générale, les services de diffusion ou de télédiffusion de programmes télévisés permettent, au bénéfice des utilisateurs téléspectateurs, la présentation d'applications interactives présentant un caractère ludique, à des fins de divertissement, ou un caractère informatif . De manière plus spécifique, ces applications interactives peuvent être présentées soit par télédiffusion, à partir de la tête de réseau de télédiffusion par exemple, soit à partir d'un logiciel embarqué au niveau du décodeur. Dans les deux cas, des mesures visant à vérifier l'audience de telles applications interactives permettent, à partir d'un module de mesure d'audience, interconnecté au décodeur ou, le cas échéant, intégré a ce dernier, de connaître au moins 1 ' instant de sélection et donc de lancement de l'application interactive par l'utilisateur, lorsque cette application, télédiffusée, est identifiable par l'intermédiaire du triplet DVB, pour Digi tal Video Broadcasting, classique, ainsi que l'instant précis où cet utilisateur quitte cette application pour sélectionner un autre programme télédiffusé par exemple, lui-même identifié par un triplet DVB différent. Ces informations peuvent être transmises, soit par une liaison RTC par modem ou, le cas échéant, par une liaison spécialisée vers un organisme gestionnaire d' audimétrie, afin de prendre en compte les résultats d'audience et de temps d'écoute par exemple.In general, television program broadcasting or broadcasting services allow, for the benefit of viewer users, the presentation of interactive applications of a playful nature, for entertainment purposes or for information purposes. More specifically, these interactive applications can be presented either by television broadcasting, from the head of the television broadcasting network for example, or from software embedded at the decoder. In both cases, measures aimed at verifying the audience of such interactive applications make it possible, from an audience measurement module, interconnected with the decoder or, if necessary, integrated into the latter, to know at least 1 moment of selection and therefore launch of the interactive application by the user, when this application, broadcast, can be identified via the DVB triplet, for Digital Video Broadcasting, conventional, as well as the precise instant when this user exits this application to select another broadcast program for example, itself identified by a different DVB triplet. These informations can be transmitted, either by a PSTN link by modem or, if necessary, by a specialized link to an audimetry management body, in order to take into account the results of audience and listening time for example.
Un tel mode opératoire ne permet pas une discrimination plus fine des habitudes de comportement d'écoute des utilisateurs.Such an operating mode does not allow finer discrimination of the listening behavior habits of users.
En particulier, même dans le cas de l'utilisation de gestionnaires de programmes ou applications interactives télédiffusés actuels tels que OPEN-TV®, il n'est pas possible de savoir dans quelle partie de l'application l'utilisateur a passé la majorité de son temps de connexion à l'application interactive sélectionnée.In particular, even in the case of the use of current broadcast program managers or interactive applications such as OPEN-TV ® , it is not possible to know in which part of the application the user has spent the majority of its connection time to the selected interactive application.
En outre, une application interactive embarquée dans le décodeur, par exemple le menu général du décodeur, n'est généralement pas identifiée par un triplet DVB. Ce type d'application ne peut donc pas être intégré au niveau de la mesure d'audience.In addition, an interactive application embedded in the decoder, for example the general menu of the decoder, is generally not identified by a DVB triplet. This type of application cannot therefore be integrated at the audience measurement level.
La présente invention a pour objet de remédier aux inconvénients précités des processus de 1 ' art antérieur mis en œuvre.The object of the present invention is to remedy the aforementioned drawbacks of the processes of the prior art implemented.
En particulier, un objet de la présente invention est la mise en œuvre d'un procédé de mesure d'audience d'applications interactives télédiffusées ou embarquées sur un décodeur de récepteur de télévision, permettant un suivi du comportement d'écoute et de réaction de l'utilisateur d'une grande précision. Un autre objet de la présente invention est en outre, grâce à la mise en œuvre d'un suivi du comportement d'écoute et de réaction de l'utilisateur, l'obtention de véritables profils comportementaux de chaque utilisateur.In particular, an object of the present invention is the implementation of a method for measuring the audience of interactive television or embedded applications on a television receiver decoder, allowing monitoring of the listening and reaction behavior of the user with great precision. Another object of the present invention is further, thanks to the implementation of behavior monitoring listening and reacting to the user, obtaining real behavioral profiles for each user.
Un autre objet de la présente invention est également, indépendamment du caractère télédiffusé ou embarqué des diverses applications interactives, la mise en œuvre d'un procédé de mesure d'audience d'applications inter-applications particulièrement fiable et précis.Another object of the present invention is also, independently of the broadcast or on-board nature of the various interactive applications, the implementation of a particularly reliable and precise method for measuring the audience of inter-application applications.
Un autre objet de la présente invention est également, indépendamment du caractère télédiffusé ou embarqué des diverses applications interactives, la mise en œuvre d'un procédé de mesure d'audience d'applications intra-applications particulièrement fiable et précis, les différentes scènes fonctionnelles de toute application pouvant faire l'objet d'une mesure d'audience de scène spécifique, afin de permettre de classifier toute application interactive compte tenu des résultats d'audience potentielle ou réelle composant celle-ci.Another object of the present invention is also, independently of the broadcast or on-board nature of the various interactive applications, the implementation of a particularly reliable and precise method for measuring the audience of intra-application applications, the different functional scenes of any application that can be the subject of a specific scene audience measurement, in order to classify any interactive application taking into account the results of potential or real audience composing it.
Le procédé de mesure d'audience d'applications interactives, objet de la présente invention, une application interactive étant reçue par un utilisateur et représentée sur un récepteur muni d'un système de visualisation, la mesure d'audience étant effectuée par détection de l'application par un dispositif de mesure d'audience connecté au récepteur, est remarquable en ce qu'il consiste, pour une application interactive subdivisée en étapes de représentation significatives successives, à transmettre du récepteur au dispositif de mesure d'audience, lors du franchissement de chaque étape significative, une information représentative de cette application et de l'étape significative franchie. Le procédé objet de la présente invention trouve application à la gestion automatisée des applications interactives, télédiffusées à partir d'une tête de réseau de télédiffusion ou embarquées sur un décodeur de récepteur de télédiffusion.The method for measuring the audience of interactive applications, object of the present invention, an interactive application being received by a user and represented on a receiver provided with a display system, the audience measurement being carried out by detection of the application by an audience measurement device connected to the receiver, is remarkable in that it consists, for an interactive application subdivided into successive significant representation steps, to be transmitted from the receiver to the audience measurement device, when crossing of each significant step, information representative of this application and of the significant step taken. The method which is the subject of the present invention finds application in the automated management of interactive applications, televised from a head end of a television broadcasting network or embedded on a decoder of a television broadcasting receiver.

FIGS. 3a and 3b represent, by way of nonlimiting example, a succession of screen pages of a specific interactive application allowing the sending of successive messages to the measurement device according to the process shown in Figure 2.
Une description plus détaillée du procédé de mesure d'audience d'applications interactives télédiffusées ou embarquées sur un décodeur de récepteur de télévision ou d'un enregistreur vidéo, objet de l'invention, sera maintenant donnée en liaison avec la figure la et les figures suivantes.A more detailed description of the method for measuring the audience of interactive television or embedded applications on a decoder of a television receiver or a video recorder, object of the invention, will now be given in conjunction with FIG. following.
D'une manière générale, on rappelle qu'un décodeur équipe habituellement des appareils récepteurs . de télévision ou, le cas échéant, les" enregistreurs vidéo. Ce décodeur se présente le plus souvent sous forme d'un module connecté au réseau de télédiffusion de programmes . Le module constitutif du décodeur permet, outre les opérations nécessaires à la réception des programmes télédiffusés, d'effectuer la mise en œuvre de fonctions spécifiques qui ne sont pas intégrées au téléviseur récepteur, ces fonctions comportant par exemple le contrôle d'accès aux émissions télédiffusées et une liaison avec une voie dite de retour vers l'autorité chargée de la gestion du réseau de télédiffusion par l'intermédiaire d'une ligne téléphonique par exemple, directement raccordée au module décodeur.In general, it is recalled that a decoder usually equips receiving devices. television or, where appropriate, " video recorders. This decoder is most often in the form of a module connected to the television broadcasting network. The module constituting the decoder allows, in addition to the operations necessary for receiving programs to carry out the implementation of specific functions which are not integrated into the television receiver, these functions comprising for example the control of access to the televised broadcasts and a connection with a so-called return channel to the authority responsible for management of the broadcasting network via a telephone line, for example, directly connected to the decoder module.
Ainsi, le module décodeur comporte une voie de sortie connectée au récepteur de télévision ou à l'enregistreur vidéo pour assurer la transmission du programme télédiffusé en clair après décodage, ainsi qu'une sortie de liaison au réseau téléphonique commuté par exemple, pour assurer les opérations de gestion par l'intermédiaire de la voie de retour. Le procédé objet de la présente invention permet notamment de s'affranchir des contraintes de détection de certains paramètres physiques des signaux de programme télédiffusé, tels que par exemple la fréquence porteuse ou le triplet DVB de ces derniers.Thus, the decoder module includes an output channel connected to the television receiver or to the video recorder to ensure the transmission of the broadcast program in clear after decoding, as well as a link output to the switched telephone network for example, to ensure the management operations via the return path. The method which is the subject of the present invention makes it possible in particular to overcome the constraints of detection of certain physical parameters of the broadcast program signals, such as for example the carrier frequency or the DVB triplet of the latter.
En particulier, en référence à la figure la, on se place dans la situation de départ S selon laquelle une application interactive IAI est reçue par un utilisateur sur son récepteur de télévision par exemple et représentée sur ce dernier, muni bien entendu d'un système de visualisation.In particular, with reference to FIG. La, we place ourselves in the starting situation S according to which an interactive IAI application is received by a user on his television receiver for example and represented on the latter, of course provided with a system of visualization.
On comprend en particulier qu'un dispositif de mesure d'audience est d'autre part connecté au récepteur par l'intermédiaire du décodeur, ainsi que mentionné précédemment dans la description, en vue d'effectuer une mesure d'audience par détection de l'application interactive utilisée par l'utilisateur lorsque cette application interactive est affichée sur le récepteur de télévision de ce dernier. En particulier, on considère une application interactive donnée IAI, laquelle est subdivisée en étapes significatives, notées SSi, ces étapes significatives étant bien entendu des étapes de représentation significatives successives, ainsi qu'il sera décrit ultérieurement dans la description.It will be understood in particular that an audience measurement device is on the other hand connected to the receiver via the decoder, as mentioned previously in the description, with a view to carrying out an audience measurement by detecting the interactive application used by the user when this interactive application is displayed on the latter's television receiver. In particular, we consider a given interactive application IAI, which is subdivided into significant steps, denoted SSi, these significant steps being of course successive significant representation steps, as will be described later in the description.
Ainsi que représenté sur la figure la, le procédé objet de l'invention consiste, pour l'application interactive IAI considérée, subdivisée en étapes de représentations significatives successives SSi, à transmettre, à l'étape T, du récepteur de télévision, à partir du décodeur par exemple, au dispositif de mesure d'audience MA, une information représentative de l'application et de l'étape significative franchie.As shown in FIG. 1 a, the method which is the subject of the invention consists, for the interactive application IAI considered, subdivided into stages of successive significant representations SSi, to be transmitted, in stage T, from the television receiver, from from the decoder for example to the measuring device MA audience, information representative of the application and the significant step taken.
En référence à la figure la, on comprend que, à chaque franchissement de chaque étape significative SSi, le procédé, objet de la présente invention, consiste à transmettre avec un numéro d'identification de l'application interactive IAI un numéro de référence ou de code de l'étape franchie SSi.Referring to FIG. 1 a, it is understood that, at each crossing of each significant step SSi, the method which is the subject of the present invention consists in transmitting with a identification number of the interactive application IAI a reference number or code of the step taken SSi.
L'étape T de transmission pouvant concerner plusieurs franchissements d'étapes significatives, peut alors être suivie d'une étape C de calcul d'audience inter ou intra-applications dans les conditions qui seront décrites ultérieurement dans la description.The transmission step T which may relate to several significant steps being crossed, can then be followed by a step C of calculation of inter or intra-application audience under the conditions which will be described later in the description.
D'une manière générale, on indique que le calcul d'audience inter-applications peut être réalisé à partir de toute étape significative de lancement d'une application, c'est-à-dire la première étape de mise en œuvre de cette application, laquelle peut être considérée comme significative du lancement de l'application considérée par l'utilisateur, alors que le calcul d'audience intra-applications peut être effectué pour l'application interactive IAI considérée et pour chacune de ces applications à partir des informations et des codes attribués à chaque étape significative ultérieure à l'écran de lancement de l'application considérée.In general, it is indicated that the inter-application audience calculation can be carried out from any significant stage of launching an application, that is to say the first stage of implementation of this application. , which can be considered as significant for the launch of the application considered by the user, while the intra-application audience calculation can be carried out for the interactive IAI application considered and for each of these applications from information and codes assigned to each significant step subsequent to the launch screen of the application in question.
D'une manière générale, et pour la mise en œuvre de l'étape de transmission T représentée à la figure la, on indique, en référence à la figure lb, que, pour une application interactive déterminée IAI donnée, les étapes de représentations significatives successives comprennent au moins la représentation d'une page écran d'accueil ou du lancement de l'application télédiffusée, cette représentation correspondant à l'étape significative SSi sur la figure lb, le cas échéant et en fonction de la nature de l'application et du caractère ludique ou non de celle-ci, des pages écrans de lancement de groupes de scènes constitutives d'une unité fonctionnelle interactive dans l'application considérée, les étapes significatives successives correspondantes de rang 1 < i < n étant définies à l'initiative de l'opérateur ou du distributeur d'application interactive en fonction de la nature de l'application interactive considérée.In general, and for the implementation of the transmission step T represented in FIG. 1a, it is indicated, with reference to FIG. 1b, that, for a given interactive application IAI given, the stages of significant representations successive include at least the representation of a home screen page or of the launch of the broadcast application, this representation corresponding to the significant step SSi in FIG. 1b, if applicable and as a function of the nature of the application and of the playful nature or not thereof, of the screen pages of launching of groups of scenes constituting an interactive functional unit in the application considered, the corresponding successive significant steps of rank 1 <i <n being defined on the initiative of the operator or distributor of interactive application as a function of the nature of the interactive application considered.

A titre d'exemple non limitatif, et pour une application distribuée par la société TPS, pour Télévisio par Satelli te, en France, application désignéeBy way of nonlimiting example, and for an application distributed by the company TPS, for Télévisio by Satelli te, in France, designated application
BANDIAGRA ®, une telle application peut être représentée schématiquement comme un premier menu d'introduction qui permet à l'abonné de sélectionner le jeu qu'il souhaite exécuter. Lorsque le jeu choisi a été lancé, l'abonné peut, soit revenir au menu d'origine, soit commuter, c'est-à-dire zapper sur un autre programme. Le retour au menu est aussi automatique lorsque l'abonné utilisateur a terminé sa partie de jeu.BANDIAGRA ® , such an application can be represented schematically as a first introduction menu which allows the subscriber to select the game he wishes to run. When the chosen game has been launched, the subscriber can either return to the original menu or switch, i.e. zap to another program. The return to the menu is also automatic when the user subscriber has finished his game.
Dans un tel contexte, les étapes significatives de 1 ' exécution peuvent être : le lancement de l'application, c'est-à-dire la présentation du menu principal ; le lancement de chaque jeu ; l'arrêt de l'application, cas de la commutation ou zapping, sur un autre programme.In such a context, the significant stages of execution can be: launching the application, i.e. presenting the main menu; the launch of each game; termination of the application, in the case of switching or zapping, on another program.
Pour assurer la transmission de l'information représentative de l'application et de l'étape significative franchie, une telle transmission peut être réalisée à partir d'un message spécifique contenant un ensemble de paramètres comprenant au moins, ainsi que représenté en figure le, une variable d'identification de l'application interactive, variable notée IAID, et bien entendu une variable d'identification de l'étape significative franchie,, c'est-à-dire le code de l'étape SSi précitée.To ensure the transmission of the information representative of the application and of the significant step taken, such a transmission can be carried out on the basis of a specific message containing a set of parameters comprising at least, as shown in FIG. a variable for identifying the interactive application, a variable denoted IAID, and of course a variable for identifying the significant step taken, ie the code for the step SSi mentioned above.
En outre, ainsi que représenté en figure le, l'ensemble de paramètres constitutifs du message peut comprendre une variable spécifique représentative d'une option relative à l'étape significative franchie, cette variable d'option étant notée OSSj .In addition, as shown in FIG. 1 a, the set of parameters constituting the message may include a specific variable representative of an option relating to the significant step taken, this option variable being denoted OSSj.
On comprend en particulier que pour une application interactive à choix multiples, ces choix peuvent être réalisés par l'utilisateur, à partir de la télécommande du récepteur de télévision, sur la base d'un arbre décisionnel qui lui est présenté sur l'écran de visualisation de l'application interactive considérée. Pour une étape SSi actuelle, l 'utilisateur• peut alors bénéficier de la possibilité de plusieurs choix et, en conséquence, faire le choix d'une option déterminée parmi cette pluralité. Ainsi, la variable d'option relative à l'étape significative franchie, variable OSSij, permet- elle de représenter la possibilité des choix précités parmi la pluralité des choix et de suivre en quelque sorte le comportement de l'utilisateur, et par là, d'une pluralité d'utilisateurs constituant un groupe d'utilisateurs spécifiques.It is understood in particular that for an interactive multiple choice application, these choices can be made by the user, from the remote control of the television receiver, on the basis of a decision tree which is presented to him on the screen of visualization of the interactive application considered. For a current step SSi, the user can then benefit from the possibility of several choices and, consequently, make the choice of a determined option from among this plurality. Thus, the option variable relating to the significant step taken, variable OSSi j , allows it to represent the possibility of the aforementioned choices among the plurality of choices and to follow in a way the behavior of the user, and thereby, of a plurality of users constituting a group of specific users.
De préférence, ainsi que représenté en outre en figure le, l'information représentative de l'application et de l'étape significative franchie peut comprendre un champ de données représentatif de la date et de l'heure de franchissement de l'étape significative, ce champ de données étant représenté sur la figure le de manière classique par un champ relatif au quantième de l'année YY, un champ relatif au mois de l'année MM, un champ relatif au jour DD, un champ relatif à l'heure HH, un champ relatif aux minutes mn et enfin, un champ relatif aux secondes ss.Preferably, as also shown in FIG. 1 a, the information representative of the application and of the significant step taken may include a data field representative of the date and time of crossing of the significant step, this data field being represented in FIG. 1a in a conventional manner by a field relating to the calendar of the year YY, a field relating to the month of the year MM, a field relating to the day DD, a field relating to the time HH, a field relating to minutes mn and finally, a field relating to seconds ss.
A titre d'exemple non limitatif, il est également possible de prévoir, si nécessaire, un champ relatif à des fractions de seconde, l'ensemble des champs précités, année, mois, jour, heure, minutes, secondes, et le cas échéant fraction de seconde, ne pouvant être activé que lors de l'existence d'une option effectuée par l'utilisateur et en conséquence lors de la sélection par ce dernier de cette option engendrant la création de la variable d'option OSSij considérée.By way of nonlimiting example, it is also possible to provide, if necessary, a field relating to fractions of a second, all of the aforementioned fields, year, month, day, hour, minutes, seconds, and if necessary fraction of a second, can only be activated during the existence of an option made by the user and consequently during the selection by the latter of this option causing the creation of the option variable OSSij considered.
D'une manière générale, on indique que chaque variable et chaque champ de variable est avantageusement constitué par une variable alphanumérique.In general, it is indicated that each variable and each variable field is advantageously constituted by an alphanumeric variable.
Enfin, en ce qui concerne la variable d'identification de l'application interactive IAID, on indique que celle-ci, ainsi que représenté également en figure le, peut comporter un champ de données alphanumériques représentatives de 1 ' autorité assurant la représentation de l'application interactive, ce champ étant noté DIF sur la figure le. L'autorité assurant la représentation de l'application interactive est celle qui assure, soit la télédiffusion du programme télédiffusé lorsque l'application interactive est transmise à partir d'une tête de réseau de télédiffusion par exemple, ou le cas échéant l'autorité qui assure la distribution de l'application interactive et l'intégration de cette dernière dans un décodeur par exemple.Finally, with regard to the identification variable of the interactive application IAID, it is indicated that this, as also represented in the, can include a field of alphanumeric data representative of the authority ensuring the representation of the interactive application, this field being noted DIF in the figure. The authority ensuring the representation of the interactive application is that which ensures either the broadcasting of the broadcast program when the interactive application is transmitted from a head end of the broadcasting network for example, or if necessary the authority which distributes the interactive application and integrates it into a decoder, for example.
Ainsi que représenté en outre en figure le, la variable d'identification de l'application interactive IAID comporte en outre un champ représentatif du type de récepteur utilisé, ce champ étant noté COD sur la figure le et pouvant correspondre, par exemple, au type de format d'affichage du téléviseur, format 16/9 ou 4/3, ou d'autres paramètres de réception spécifiques du récepteur considéré. Enfin, la variable d'identification de l'application interactive IAID comprend, ainsi que représenté sur la figure le, un champ de données alphanumériques représentatif d'une référence utilisateur, ce champ étant noté USID. On indique d'une manière plus particulière que ce champ de données représentatif de la référence utilisateur peut être codé et que le code utilisé est indépendant et n'autorise aucun accès non habilité à des données personnelles relatives à l'utilisateur considéré. Le mode opératoire pour réaliser la transmission de l'information représentative de l'application et de l'étape significative franchie., pour permettre d'assurer la mise en œuvre du procédé objet de la présente invention, sera maintenant décrit en liaison avec la figure 2. Sur la figure 2, on a représenté le récepteur TV, noté Récepteur, auquel est par exemple intégré un décodeur spécifique. Le décodeur spécifique comprend un module logiciel de gestion du procédé objet de la présente invention, et bien entendu de l'exécution de l'application interactive IAI considérée. On rappelle que l'application interactive IAI permet d ' exécuter : l'affichage d'un menu de sélection/achat par l'utilisateur abonné,. - le déplacement du curseur par une télécommande du récepteur de télévision et en particulier la sélection ou l'achat, c'est-à-dire le choix, dans les différentes options offertes à l'utilisateur pour l'application interactive considérée. En outre, l'application interactive précitée permet d'engendrer une commande de lancement de message, notée Commande_message, permettant l'appel d'une primitive spécifique, telle qu'une primitive MA_notify dans un contexte de type OPEN-TV ®, la primitive MA_notify précitée désignant de manière plus spécifique une primitive de mesure d'audience permettant d'engendrer la structure de message représentée en figure le par exemple, pour assurer la transmission de l'information représentative de l'application et de l'étape significative franchie. La structure de message M est alors transmise du. récepteur à l'appareil de mesure d'audience par l'intermédiaire d'une liaison série LS par exemple. L'appareil de mesure d'audience procède alors à la mémorisation des données contenues dans la structure de message M précitée et peut assurer, suite à la mémorisation d'une- quantité d'information suffisante relative aux informations de franchissement d'étape significative d'une ou plusieurs applications, ces informations constituant des données de mesure d'audience d'applications interactives, puis à la transmission de ces données par la voie de retour sur le réseau téléphonique commuté par exemple.As also shown in FIG. 1 a, the identification variable of the interactive application IAID also includes a field representative of the type of receiver used, this field being denoted COD in FIG. Le and possibly corresponding, for example, to the type TV display format, 16: 9 or 4: 3 format, or other specific reception parameters of the receiver concerned. Finally, the identification variable of the interactive application IAID comprises, as shown in FIG. 1 a, an alphanumeric data field representative of a user reference, this field being denoted USID. It is indicated in a more particular way that this data field representative of the user reference can be coded and that the code used is independent and does not allow any unauthorized access to personal data relating to the user considered. The procedure for transmitting information representative of the application and the significant step taken., to enable the implementation of the method which is the subject of the present invention, will now be described in connection with FIG. 2. In FIG. 2, the TV receiver, denoted Receiver, is shown. for example, a specific decoder is integrated. The specific decoder comprises a software module for managing the process which is the subject of the present invention, and of course the execution of the interactive application IAI considered. Remember that the IAI interactive application allows you to execute: the display of a selection / purchase menu by the subscribed user. - the movement of the cursor by a remote control of the television receiver and in particular the selection or the purchase, that is to say the choice, in the different options offered to the user for the interactive application considered. In addition, the aforementioned interactive application allows to generate a message from launch control, denoted Commande_message, allowing the call to a specific primitive such as a primitive MA_notify in a context type OPEN-TV ®, the primitive MA_notify mentioned above designating more specifically an audience measurement primitive allowing to generate the message structure represented in the figure for example, to ensure the transmission of information representative of the application and of the significant step taken. The message structure M is then transmitted from. receiver to the measuring device audience by means of a serial link LS for example. The audience measurement device then stores the data contained in the aforementioned message structure M and can ensure, following the storage of a sufficient quantity of information relating to the information on the passage of significant step d one or more applications, this information constituting audience measurement data of interactive applications, then the transmission of this data by the return channel on the switched telephone network for example.
