Description

Procédé pour présenter sur un écran d'affichage d'un téléviseur une image composite combinant une image de télévision et un contenu informatif de données Internet Method for presenting on a television display screen a composite image combining a television image and informative content of Internet data
L'invention concerne la présentation et l'utilisation des informations transmises par le réseau Internet. On connaît des appareils, que l'on appellera dans la suite "terminaux Internet", qui se présentent sous la forme d'un boîtier destiné à être connecté d'une part au réseau téléphonique et d'autre part à un téléviseur. Le terminal Internet est pourvu de moyens de contrôle, par exemple sous la forme d'une télécommande, qui permettent de com- mander l'accès à telle ou telle ressource Internet, la récupération des informations souhaitées et leur affichage sur l'écran du téléviseur auquel est relié le terminal Internet.The invention relates to the presentation and use of information transmitted over the Internet. Devices are known, which will hereinafter be called "Internet terminals", which are in the form of a box intended to be connected on the one hand to the telephone network and on the other hand to a television set. The Internet terminal is provided with control means, for example in the form of a remote control, which make it possible to control access to such or such Internet resource, retrieval of the desired information and their display on the television screen. to which the Internet terminal is connected.
Une telle configuration n'est cependant pas limitative, et diverses variantes peuvent être envisagées, notamment une transmission par une voie autre qu'une ligne téléphonique, telle que réseau câblé, radiotéléphonie cellulaire (GSM), radiotéléphonie sur boucle locale, réception de données par satellite, etc.Such a configuration is however not limiting, and various variants can be envisaged, in particular transmission by a channel other than a telephone line, such as cable network, cellular radiotelephony (GSM), radiotelephony on local loop, reception of data by satellite, etc.
Le téléviseur est utilisé en tant que périphérique d'affichage des données informatiques produites par le terminal Internet. Le terminal Internet fournit à cet effet soit un signal appliqué directement aux étages vidéo du téléviseur via une prise de péritélévision, soit un signal UHF modulé appliqué à la prise d'antenne du téléviseur.The television is used as a display device for computer data produced by the Internet terminal. The Internet terminal provides for this purpose either a signal applied directly to the video stages of the television via a SCART socket, or a modulated UHF signal applied to the antenna socket of the television.
L'un des buts de la présente invention est de permettre l'affichage sur l'écran du téléviseur d'une image composite combinant une image de télévision proprement dite, transmise au téléviseur par voie hertzienne ou par un réseau câblé, et d'une image de données numériques informatiques produites par le terminal Internet relié à ce téléviseur.One of the aims of the present invention is to allow the display on the television screen of a composite image combining a television image proper, transmitted to the television by radio or by a cable network, and of a image of digital computer data produced by the Internet terminal connected to this television.
L'intérêt d'un tel procédé réside, d'une part, dans la possibilité d'individualiser l'affichage des données informatiques en fonction du destinataire (ce qui n'est pas le cas de l'image de télévision) et, d'autre part et surtout, de réaliser une interactivité avec le spectateur, la liaison avec le site Internet pouvant être utilisé comme voie de retour pour la transmission d'informations en réponse émises par le spectateur, telles que vote, demande d'informations sur un sujet présenté par l'image de télévision, participation active et directe à un jeu télédiffusé, etc.The interest of such a method resides, on the one hand, in the possibility of individualizing the display of the computer data according to the recipient (which is not the case of the television image) and, d 'other part and above all, to achieve interactivity with the spectator, the link with the website can be used as a return channel for the transmission of response information sent by the spectator, such as voting, request for information on a subject presented through the television image, active and direct participation in a televised game, etc.
À cet effet, le procédé de l'invention est caractérisé par les étapes consistant à : établir une connexion à une ressource Internet distante à partir d'un terminal Internet relié au téléviseur, et charger des don- nées Internet à partir de cette ressource ; à partir des données Internet chargées, déterminer la position sur l'écran d'au moins une fenêtre d'affichage et le contenu informatif correspondant de ces données Internet ; recevoir sur une entrée du téléviseur le signal d'image de télévision ; commander le signal d'entrée du téléviseur de manière à faire apparaître sur l'écran d'affichage une image composite comprenant, dans la région délimitée par ladite fenêtre, le contenu informatif des données Internet et, sur le reste de l'écran, l'image de télévision.To this end, the method of the invention is characterized by the steps consisting in: establishing a connection to a remote Internet resource from an Internet terminal connected to the television set, and loading Internet data from this resource; from the loaded Internet data, determining the position on the screen of at least one display window and the corresponding informative content of this Internet data; receiving on a television input the television image signal; controlling the input signal from the television so as to display on the display screen a composite image comprising, in the region delimited by said window, the informative content of Internet data and, on the rest of the screen, the television picture.
Dans une première forme de mise en oeuvre du procédé de l'invention, l'étape de commande du signal d'entrée du téléviseur comporte un pilotage sélectif de la broche de commutation rapide d'une prise de pé- ritélévision du téléviseur pendant les périodes correspondant au balayage de la fenêtre, et la substitution du signal d'image de télévision par le contenu informatif des données Internet pendant ces périodes. Dans une seconde forme de mise en oeuvre du procédé de l'inven- tion, l'étape de commande du signal d'entrée du téléviseur comporte l'application au téléviseur d'un signal vidéo composite multiplexe incluant le contenu informatif des données Internet pendant les périodes correspondant au balayage de la fenêtre, et le signal d'image de télévision le reste du temps. Selon un certain nombre de caractéristiques subsidiaires avantageuses :In a first form of implementation of the method of the invention, the step of controlling the input signal of the television set includes a selective piloting of the fast switching pin of a television viewing socket during the periods corresponding to the scanning of the window, and the substitution of the television image signal by the informative content of the Internet data during these periods. In a second form of implementation of the method of the invention, the step of controlling the television input signal comprises the application to the television of a multiplex composite video signal including the informative content of Internet data during the periods corresponding to the scanning of the window, and the television image signal the rest of the time. According to a certain number of advantageous subsidiary characteristics:
— l'image composite est une superposition d'une page de données Internet plein écran et du signal d'image de télévision, la page de données Internet plein écran comprenant le contenu informatif des données Internet dans la région de l'écran délimitée par la fenêtre, et une plage uniforme de couleur définie comme transparente sur le reste de l'écran ; le signal d'image de télévision est au moins partiellement constitué d'informations de télétexte ; le procédé comprend en outre les étapes suivantes : introduction par l'utilisateur dans le terminal Internet de données en réponse au contenu informatif affiché sur le téléviseur ; et transmission par le terminal Internet de ces données à un site Internet distant.The composite image is an overlay of a full screen Internet data page and of the television image signal, the full screen Internet data page comprising the informative content of the Internet data in the region of the screen delimited by the window, and a uniform range of color defined as transparent on the rest of the screen; the television picture signal is at least partially made up of teletext information; the method further comprises the following steps: introduction by the user into the Internet terminal of data in response to the informative content displayed on the television; and transmission by the Internet terminal of this data to a remote Internet site.
D'autres caractéristiques de l'invention apparaîtront à la lecture de la description ci-dessous d'un exemple de mise en oeuvre, en référence à la figure annexée qui est une représentation schématique fonction- nelle des différents éléments intervenant dans la mise en oeuvre du procédé de l'invention.Other characteristics of the invention will appear on reading the description below of an exemplary implementation, with reference to the appended figure which is a functional schematic representation of the various elements involved in the implementation of the process of the invention.
00
Sur la figure 1 , la référence 10 désigne un terminal Internet d'un type général en lui-même connu, c'est-à-dire se présentant sous la forme d'un boîtier destiné à être relié à un téléviseur 12 pour l'affichage des données retournées par le réseau Internet, ce boîtier comportant, pour l'introduction de commandes de navigation, un récepteur 14 tel qu'un récepteur infrarouge piloté par une télécommande 16 à la dispo- sition de l'utilisateur.In FIG. 1, the reference 10 designates an Internet terminal of a general type which is in itself known, that is to say in the form of a box intended to be connected to a television set 12 for the display of the data returned by the Internet, this unit comprising, for the introduction of navigation commands, a receiver 14 such as an infrared receiver controlled by a remote control 16 available to the user.
Le terminal Internet 10 peut être pourvu d'un lecteur 18 de carte à microcircuit, par exemple pour lire une carte dans laquelle sont mémorisées les données de connexion au fournisseur d'accès Internet, carte qui est par exemple adressée à l'utilisateur après souscription d'un abonnement à ce fournisseur.The Internet terminal 10 can be provided with a microcircuit card reader 18, for example for reading a card in which the connection data to the Internet access provider are stored, a card which is for example addressed to the user after subscription a subscription to this provider.
Pour l'accès à un site Internet distant tel que 20, le boîtier comprend un modem relié de manière appropriée au réseau téléphonique commuté 22, avec une liaison bidirectionnelle via les protocoles classiques (TCP/IP) utilisés pour ce type de liaison. Le téléviseur possède une entrée de signal de télévision 24, par exemple un signal hertzien ou de réseau câblé.For access to a remote Internet site such as 20, the box includes a modem appropriately connected to the switched telephone network 22, with a bidirectional link via the conventional protocols (TCP / IP) used for this type of link. The television has a television signal input 24, for example example a radio signal or a cable network signal.
Ce signal, désigné TV, va produire l'affichage d'une image de télévision 26 sur l'écran du téléviseur 12.This signal, designated TV, will produce the display of a television image 26 on the screen of the television set 12.
Le but de l'invention est de réaliser une image composite combi- nant cette image de télévision 26 à des données informatiques incrustées dans une ou plusieurs fenêtre(s) 28 pour l'affichage d'un contenu informatique correspondant 30 provenant de données retournées par le réseau Internet.The object of the invention is to produce a composite image combining this television image 26 with computer data embedded in one or more window (s) 28 for the display of corresponding computer content 30 coming from data returned by the Internet.
Le spectateur va alors disposer, outre le son et l'image du signal TV (qui ne contient pas d'information spécifique), d'un ou plusieurs "pavés" Internet incrustés dans cette image et pouvant évoluer dynamiquement en fonction de commandes envoyées par le site Internet distant.The spectator will then have, in addition to the sound and the image of the TV signal (which does not contain specific information), one or more Internet "blocks" embedded in this image and which can evolve dynamically according to commands sent by the remote website.
On notera incidemment que l'image de télévision peut être partiellement, ou même totalement, constituée d'un signal de télétexte, donc pouvant combiner des informations purement analogiques et des données numériques, ces dernières étant transmises par le signal TV pendant les périodes de retour de trame, comme cela est en soi bien connu. Pour réaliser le signal composite, le terminal Internet récupère le signal de synchronisation SYNC du téléviseur, se synchronise sur ce si- gnal, et vient piloter par un signal CTRL la broche de commutation rapide de la prise de péritélévision du téléviseur 12 pendant les périodes correspondantes aux balayage de la (des) fenêtre(s) 28, en remplaçant alors pendant ces périodes l'image de télévision par le contenu informatif INFO des données Internet. En variante, notamment pour les téléviseurs non munis de prise de péritélévision, le terminal Internet peut récupérer le signal UHF de télévision TV et remoduler un signal UHF désigné TVC appliqué sur l'entrée d'antenne du téléviseur, ce signal combinant l'image de télévision 26 et les fenêtres Internet 28, le tout modulé à une fréquence UHF ap- propriée.Incidentally, it will be noted that the television picture can be partially, or even totally, made up of a teletext signal, therefore able to combine purely analog information and digital data, the latter being transmitted by the TV signal during the return periods. weft, as is well known per se. To produce the composite signal, the Internet terminal retrieves the SYNC synchronization signal from the television, synchronizes on this signal, and comes to control by a CTRL signal the fast switching pin of the television's SCART socket 12 during the corresponding periods. to the scanning of window (s) 28, then replacing during these periods the television image by the informative content INFO of the Internet data. As a variant, in particular for televisions not fitted with a scart socket, the Internet terminal can recover the UHF signal from television TV and remodulate a UHF signal designated TVC applied to the antenna input of the television, this signal combining the image of television 26 and internet windows 28, all modulated at an appropriate UHF frequency.
On notera que, dans ce procédé, les données retournées par le réseau Internet comprennent non seulement le contenu informatif 30 des fenêtres 28, mais également la position de ces fenêtres sur l'écran de téléviseur. Avantageusement, la position de ces fenêtres est définie en attri- buant aux régions de l'écran délimitées par des fenêtres un contenu informatif de données Internet de la manière habituelle, et en attribuant aux régions extérieures à ces fenêtres une plage uniforme d'une couleur définie comme transparente. Ainsi, la superposition de la plage de données Internet - qui est une plage pleine écran - et du signal d'image de télévision - également plein écran - par simple addition numérique des signaux donnera l'image composite recherchée, sans qu'il soit besoin de réaliser de multiplexage entre l'image de télévision, d'une part, et fenêtre de données Internet, d'autre part. Ce procédé selon l'invention s'applique avantageusement, par exemple, à des émissions télédiffusées de jeux, concours, votes, etc.It will be noted that, in this method, the data returned by the Internet network includes not only the informative content 30 of the windows 28, but also the position of these windows on the television screen. Advantageously, the position of these windows is defined by attributing buzzing the window-bounded regions of the screen with informative content of Internet data in the usual manner, and assigning the regions outside these windows a uniform range of a color defined as transparent. Thus, the superimposition of the Internet data range - which is a full screen range - and the television image signal - also full screen - by simple digital addition of the signals will give the desired composite image, without the need for it. multiplexing between the television image on the one hand and the Internet data window on the other. This method according to the invention advantageously applies, for example, to television broadcasts of games, contests, votes, etc.
Dans ce cas, il est possible d'afficher sur l'écran, dans les fenêtres de données, des données personnalisées en fonction du destinataire (ce qui n'est pas le cas de l'image de télévision, qui est la même pour tous). Mais surtout, il devient possible de prévoir une voie de retour d'informations, en demandant au spectateur, via sa télécommande 16, de répondre à telle ou telle question, de voter, de jouer, etc., par exemple en lui proposant de pointer et de cliquer sur telle ou telle fenêtre apparaissant sur l'écran de son téléviseur en fonction de son choix. In this case, it is possible to display on the screen, in the data windows, personalized data according to the recipient (which is not the case for the television picture, which is the same for all ). But above all, it becomes possible to provide a feedback channel, by asking the spectator, via his remote control 16, to answer such or such question, to vote, to play, etc., for example by proposing to point and to click on such or such window appearing on the screen of its television according to its choice.
