- the communication is bidirectional and the tuner can directly display the acquisition price of the work chosen according to a price indication transmitted by the transmitting station at the same time as the EAN references in response to the request.
- the transmitting station is a broadcasting station transmitting in the conventional manner (unidirectional transmission) and distinct from the recording site, it cannot receive either the user's request or the confirmation of payment for the purchase.
- the user device will then pick up the EAN references sent by this transmitting station and send the request over the Internet to a recording site, which will respond with a signal indicating the purchase price; the teletransmission will then be operated with this same record site.
- the acquired work is identical to that broadcast and identified by the broadcasting station.
- this discographic site may offer different works, in particular if the recording identical to the identified work is not available, or only with different interpreters or on different dates or places of recording.
- the discographic site can also offer several different formulas for purchasing listening rights to the works acquired: debiting an account or charging on a subscription, debiting a prepaid card (in particular debiting the microcircuit card), etc.
- Step 6 of confirmation of purchase can immediately follow the previous steps, which is conducive to a certain spontaneity of the purchase. In some cases, however, it may be useful to defer this confirmation step from the previous steps.
- the study of several purchase proposals may require a concentration which would be may be convenient in certain circumstances (the user listens to the radio while driving a vehicle) or even impossible when the link with the record site is not available time of listening (the typical case being that of listening to the radio on a portable music player or on a car radio, unless the user has a data transmission link by radiotelephony).
- the EAN references are stored in the device for later use; in the case where the device comprises a microcircuit, in particular a microcircuit integrated into a card, the EAN references can be stored in the memory of this microcircuit ' .
- the broadcast receiver tuner can be a separate item from the Internet tuner.
- the receiver tuner then has its own display and listening means as well as a "PURCHASE" button OR other means of capturing the order of recording of EAN references.
- the microcircuit in particular in the form of a smart card, is separable from the two tuners and these two tuners include readers capable of communicating with the microcircuit.
- the card is then first installed in the receiver tuner; after capturing the references and storing them in the microcircuit's memory, the card is removed from the receiver tuner and installed in the reader of the Internet tuner, which continues the process by establishing communication with the recording site for receipt of the elaborate purchase proposal from the data recorded in the separable microcircuit and transmitted to the discographic site.
- the integration of the two tuners in the same device makes it possible to use a common display and common listening means in the case of a tuner receiving information broadcast in digital form on the Internet, as well as in the case of a tuner receiver and the Internet using different communication channels.
- the tuner can for example automatically record a history of the EAN references of the works listened to recently and, on request, present a list later to allow the user to select the desired work. Payment for the purchase can be made by the same procedures as those disclosed by the aforementioned French applications 98 10543 and 98 15377.
- the same microcircuit in particular that of a smart card, participates in the payment of the purchase and stores information concerning the nature of the listening rights purchased.
- This makes it possible to guarantee, with a high level of security, compliance with the conditions of purchase of listening rights; this security is further enhanced if the same card also performs the decryption of the downloaded music and at least part of the data decompression process.
- the digital identification data is replaced by a channel identifier (for example the frequency of the FM station) and a time (in the broad sense, which can include the date); this information is transmitted by the download / streaming means to a server, which consults a table ("playlist" of the radio station) indicating the sequences transmitted on this channel at this time (which supposes a common chronological reference, for example date and time GMT), and thus recognizes the sequence to be proposed to the user.
- This table can be obtained either by cooperation with the manager of the broadcasting means which transmits it to the server, or by listening to the broadcasting means and identifying the sequences.
- the digital sequence identification data (or the channel identifier and the time) can be stored in an intermediate memory, for example a removable memory subsequently connected to a microcomputer connected to the Internet; this system is advantageously applicable in the case of a car radio for the purchase of pieces deemed interesting.

Procédé d'acquisition d'une séquence audio, vidéo ou textuelle auprès d'un site distant depuis un dispositif utilisateur local par télétransmission de données numériques représentatives de cette séquence Method for acquiring an audio, video or text sequence from a remote site from a local user device by remote transmission of digital data representative of this sequence
L'invention concerne l'acquisition de séquences audio, vidéo ou textuelles auprès d'un site distant depuis un dispositif utilisateur local par télétransmission de données numériques représentatives de ces séquences. Par "acquisition" on entendra ce terme dans sa double acception techni- que, c'est à dire l'obtention (chargement) de données par un dispositif pour mémorisation et/ou utilisation, et économique, en ce sens que l'obtention de ces données s'accompagne d'une contrepartie monétaire ou analogue, telle que paiement, débit d'un compte, imputation sur un abonnement, consommation d'unités prépayées, etc. Par ailleurs, bien que l'on décrira l'invention dans le cadre de séquences audio car il s'agit là de l'application la plus immédiate compte tenu des capacités actuelles des réseaux de diffusion, l'invention peut être transposée directement à l'acquisition d'autres types de données, notamment de données vidéo (images fixes ou images animées de télévision) ou de données textuelles.The invention relates to the acquisition of audio, video or text sequences from a remote site from a local user device by remote transmission of digital data representative of these sequences. By "acquisition" will be understood this term in its double technical meaning, that is to say obtaining (loading) data by a device for storage and / or use, and economical, in the sense that obtaining this data is accompanied by a monetary or similar counterpart, such as payment, debit from an account, charging to a subscription, consumption of prepaid units, etc. Furthermore, although the invention will be described in the context of audio sequences because it is the most immediate application taking into account the current capacities of broadcasting networks, the invention can be transposed directly to the acquisition of other types of data, in particular video data (still images or animated television images) or text data.
Les demandes de brevet français 9810543 du 19 août 1998 pour un "appareil de production de signaux audio pour une installation de reproduction sonore" et 9815377 du 4 décembre 1998 pour un "dispositif sécurisé, décodeur d'informations chiffrées et comprimées, notamment d'informa- tions vidéo, audio ou de texte" qui appartiennent toutes deux à la demanderesse, décrivent un dispositif - que l'on appellera par commodité "tuner Internet" - permettant de disposer chez soi d'une fonction de type "jukebox" en exploitant la richesse d'une discothèque universelle en ligne accessible en temps réel pour écoute immédiate ou ultérieure. Ces demandes décrivent la possibilité d'acquérir pour écoute des séquences audio, typiquement des œuvres musicales telles que des morceaux de musique ou des plages individuelles d'un enregistrement, convenablement sélectionnées par l'utilisateur. Les morceaux de musique sont téléchargés sous forme de paquets de données numériques chiffrées et comprimées et transmis depuis un site central au dispositif de l'utilisa- teur. La télétransmission est typiquement réalisé via Internet, c'est-à-dire par les réseaux mondiaux interconnectés reliant des sites et des utilisateurs par des routages variables et multiples pour la transmission de données sous forme numérique. On y prévoit avantageusement d'associer au tuner une carte à microcircuit pour participer à l'opération de décryptage et/ou de décompression des données ; le paiement des droits d'acquisition déclenche la télétransmission ou autorise les opérations de cryptage et/ou de décompression des données. La carte peut également participer à la transaction de paiement, soit en stockant un code qui est envoyé au site central (le code identifiant pour débit un compte utilisateur auprès de l'opérateur du site), soit en débitant un compte de l'utilisateur dans la carte (la carte étant alors de préférence du type "porte-monnaie électronique"). Un signal de confirmation du débit et/ou de l'imputation au compte utilisateur permet de créditer des comptes du site central, comprenant notamment un compte de paiement des droits d'auteur attachés à l'œuvre.French patent applications 9810543 of August 19, 1998 for an "audio signal production device for a sound reproduction installation" and 9815377 of December 4, 1998 for a "secure device, decoder of encrypted and compressed information, in particular informa - video, audio or text "which both belong to the applicant, describe a device - which will be called for convenience" Internet tuner "- allowing to have at home a function of type" jukebox "by exploiting the richness of a universal online disco accessible in real time for immediate or later listening. These requests describe the possibility of acquiring for listening audio sequences, typically musical works such as pieces of music or individual tracks of a recording, suitably selected by the user. Music tracks are downloaded as encrypted and compressed digital data packets and transmitted from a central site to the user's device. tor. Remote transmission is typically carried out via the Internet, that is to say by interconnected global networks connecting sites and users by variable and multiple routes for the transmission of data in digital form. Advantageously there is provision to associate with the tuner a microcircuit card to participate in the decryption and / or decompression operation of the data; the payment of the acquisition rights triggers the remote transmission or authorizes the operations of encryption and / or decompression of the data. The card can also participate in the payment transaction, either by storing a code which is sent to the central site (the identifier code for debiting a user account with the site operator), or by debiting a user account in the card (the card then preferably being of the "electronic purse" type). A confirmation signal of the debit and / or the allocation to the user account makes it possible to credit accounts on the central site, including in particular an account for payment of the copyright attached to the work.
Le point de départ de la présente invention consiste à compléter le tuner Internet décrit dans les demandes précitées d'une fonction de tuner tradi- tionnel permettant l'écoute, de manière en elle-même connue, de séquences télédiffusées (ce dernier terme incluant divers modes de diffusion connus tels que radiodiffusion hertzienne, par satellite ou par câble, transmission par le réseau téléphonique commuté (technologies RNIS ou ADSL) ou non (technologie T1 ) ou autre forme de transmission via Inter- net, les signaux télédiffusés pouvant être aussi bien des signaux analogiques que des signaux numériques.The starting point of the present invention consists in supplementing the Internet tuner described in the aforementioned requests with a traditional tuner function allowing the listening, in itself known manner, of televised sequences (the latter term including various known broadcasting methods such as over-the-air, satellite or cable broadcasting, transmission via the switched telephone network (ISDN or ADSL technologies) or not (T1 technology) or other form of transmission via the Internet, the broadcast signals may be as well analog signals than digital signals.
Le dispositif de l'invention combine ainsi un tuner Internet tel que décrit dans la demande française 98 10543 précitée et des modules propres à capter des signaux télédiffusés. La présente invention propose un procédé d'acquisition de données audiovisuelles utilisant un dispositif de cette nature, ainsi que des moyens adaptés à la mise en œuvre de ce procédé.The device of the invention thus combines an Internet tuner as described in the aforementioned French application 98 10543 and modules capable of picking up broadcast signals. The present invention provides a method of acquiring audiovisual data using a device of this nature, as well as means adapted to the implementation of this method.
Plus précisément, la présente invention repose sur la combinaison de deux moyens de communication distincts, à savoir : - télédiffusion, etMore specifically, the present invention is based on the combination of two distinct means of communication, namely: - television broadcasting, and
- téléchargement ou "streaming".- download or "streaming".
Le moyen de télédiffusion peut être unidirectionnel (le plus souvent, il l'est par nature) et adapté à une diffusion simultanée vers une multitude d'usa- gers ; on peut utiliser sans adaptation majeure un système existant, tel qu'une diffusion hertzienne classique (radio FM), ou un canal d'un système de diffusion par satellite ou par câble. La vitesse de transmission des données par télédiffusion est telle qu'elle permet l'exploitation de ces données en temps réel, même si elles sont en fait exploitées en différé. Le moyen de téléchargement/streaming est obligatoirement bidirectionnel, en ce qu'il permet d'obtenir à la demande telle ou telle séquence que l'utilisateur va acheter. Il s'agit par exemple d'un réseau de paquets type Internet.The broadcast medium can be unidirectional (most often, it is by nature) and suitable for simultaneous broadcasting to a multitude of users; an existing system, such as conventional radio broadcasting (FM radio), or a channel of a satellite or cable broadcasting system can be used without major adaptation. The speed of data transmission by broadcast is such that it allows the exploitation of this data in real time, even if it is in fact exploited in deferred mode. The means of downloading / streaming is necessarily bidirectional, in that it makes it possible to obtain on demand such or such sequence that the user will buy. This is for example an Internet-type packet network.
On distingue deux modes possible de diffusion : - le "streaming", où les informations audio/vidéo sont restituées sous une forme intelligible aux sens humains au fur et à mesure de leur réception, sensiblement à la vitesse à laquelle elles sont transmises, sans stockage permanent dans le système de restitution (qui ne stocke qu'une quantité limitée d'informations, par exemple correspondant à 1 seconde de restitution, pour amortir les fluctuations de courte durée du moyen de transmission) ;There are two possible modes of dissemination: - "streaming", where audio / video information is restored in a form intelligible to human senses as it is received, substantially at the speed at which it is transmitted, without storage permanent in the restitution system (which stores only a limited quantity of information, for example corresponding to 1 second of restitution, to absorb short-term fluctuations in the transmission means);
- le "téléchargement", où les informations sont stockées de manière permanente dans le système de restitution, pour une restitution future, à la vitesse où elles sont transmises. Ce système est compatible avec les média de transmission dont le débit est insuffisant pour une restitution en temps réel (par exemple : liaison Internet par modem réseau commuté : 4 koctets/s, à comparer aux 16 koctets/s d'une musique de haute qualité) et/ou d'un débit très irrégulier (liaisons Internet encombrées, même si elles sont rapides en crête : ADSL à 50 koctets/s). Selon l'invention, essentiellement :- "download", where the information is permanently stored in the restitution system, for future restitution, at the speed at which it is transmitted. This system is compatible with transmission media whose speed is insufficient for real-time playback (for example: Internet connection by dial-up network modem: 4 kbytes / s, compared to 16 kbytes / s of high-quality music ) and / or with a very irregular speed (congested Internet links, even if they are fast at peak: ADSL at 50 kbytes / s). According to the invention, essentially:
- le moyen de télédiffusion véhicule aussi une donnée numérique d'identification de la séquence. Il peut s'agir par exemple du système RDS qui véhicule une information numérique sur la porteuse FM ;- the broadcasting means also conveys digital data identifying the sequence. It may for example be the RDS system which conveys digital information on the FM carrier;
- et cette donnée numérique d'identification de la séquence est trans- mise par le moyen de téléchargement/streaming, et permet de définir la séquence proposée à la vente (ou, par proximité, des séquences voisines, par exemples celles du même album, du même auteur, du même genre).- and this digital data identifying the sequence is transmitted by the download / streaming means, and makes it possible to define the sequence offered for sale (or, by proximity, neighboring sequences, for example those from the same album, by the same author, of the same genre).
Plus précisément, le procédé de l'invention est un procédé d'acquisition d'une séquence audio, vidéo ou textuelle auprès d'un site distant depuis un dispositif utilisateur local par télétransmission de données numériques représentatives de ladite séquence, caractérisé par les étapes suivantes :More specifically, the method of the invention is a method of acquiring an audio, video or text sequence from a remote site from a local user device by remote transmission of digital data representative of said sequence, characterized by the following steps :
- réception, par le dispositif utilisateur, de signaux télédiffusés comportant des données de la séquence et des données numériques d'identi- fication de la séquence télédiffusée,- reception, by the user device, of broadcast signals comprising sequence data and digital identification data of the broadcast sequence,
- présentation à l'utilisateur de la séquence par le dispositif utilisateur,- presentation to the user of the sequence by the user device,
- production, par le dispositif utilisateur, d'une requête d'acquisition par activation sélective d'un moyen de commande du dispositif utilisateur,- production, by the user device, of an acquisition request by selective activation of a control means of the user device,
- transmission de cette requête, accompagnée des données numéri- ques d'identification correspondantes, du dispositif utilisateur au site distant,- transmission of this request, accompanied by the corresponding digital identification data, from the user device to the remote site,
- transmission des données de la séquence, du site distant au dispositif utilisateur, et- transmission of sequence data from the remote site to the user device, and
- reproduction de la séquence par le dispositif utilisateur. Très avantageusement, l'étape de transmission des données de la séquence du site distant au dispositif utilisateur est exécutée à une première vitesse de transfert de données, et l'étape de reproduction par le dispositif utilisateur est exécutée à une seconde vitesse différente de transfert de données, la première vitesse étant plus lente (typiquement, dans le cas des canaux de transmission commutés actuels) ou plus rapide (de préférence, et avec compression) que la seconde. Selon diverses caractéristiques subsidiaires avantageuses :- reproduction of the sequence by the user device. Very advantageously, the step of transmitting the sequence data from the remote site to the user device is executed at a first speed of data transfer, and the step of reproducing by the user device is executed at a second speed different from the transfer of data, the first speed being slower (typically, in the case of current switched transmission channels) or faster (preferably, and with compression) than the second.

On va maintenant décrire un exemple de réalisation de l'invention.We will now describe an embodiment of the invention.
Comme indiqué plus haut, l'invention est mise en œuvre par un dispositif de type "tuner Internet" tel que décrit dans les demandes de brevet français précitées 9810543 et 9815377, associé à un module, ci-après désigné "tuner récepteur", propre à capter des signaux télédiffusés, par exemple des circuits de réception hertzienne, par satellite ou par câble de signaux analogiques (radiodiffusion FM) ou numériques (radiodiffusion DAB). En variante ou en complément, les données de radiodiffusion pourront être des données numériques captées par les mêmes moyens que ceux permettant la mise en œuvre des fonctions connues du tuner Inter- net précitées, ces données pouvant être diffusées par les moyens de communication Internet avec cryptage (radios payantes) ou sans cryptage (radios gratuites).As indicated above, the invention is implemented by a device of the "Internet tuner" type as described in the aforementioned French patent applications 9810543 and 9815377, associated with a module, specific to "receiver tuner" to receive broadcast signals, for example radio reception circuits, by satellite or by cable of analog signals (FM broadcasting) or digital signals (DAB broadcasting). As a variant or in addition, the broadcasting data may be digital data captured by the same means as those allowing the implementation of the known functions of the aforementioned Internet tuner, this data being able to be broadcast by the Internet communication means with encryption. (pay radios) or without encryption (free radios).
Les données audio télédiffusées, qu'elles soient numériques ou analogiques, sont accompagnées d'un certain nombre de données numériques permettant leur identification, par exemple des données RDS accompagnant des émissions radio FM et comportant :The audio data broadcast, whether digital or analog, is accompanied by a certain number of digital data allowing their identification, for example RDS data accompanying FM radio broadcasts and comprising:
- des informations textuelles sur l'œuvre diffusée (titre, auteur, compositeur, interprète, etc.), qui pourront être présentées à l'utilisateur sur un afficheur du dispositif, et - des références numériques complètes de l'enregistrement, pouvant comporter notamment (et de façon non limitative) des informations relatives à l'éditeur, à l'auteur et au numéro de l'œuvre. Ces informations constituent les coordonnées permettant d'identifier de façon complète et univoque l'œuvre diffusée ; elles seront désignées ci-après "références EAN" (pour "Editeur-Auteur-Numéro").- textual information on the work broadcast (title, author, composer, performer, etc.), which can be presented to the user on a display device, and - complete digital references of the recording, which may include in particular (and without limitation) information relating to the publisher, the author and the number of the work. This information constitutes the contact details enabling a complete and unambiguous identification of the work disseminated; they will be designated hereafter "EAN references" (for "Publisher-Author-Number").
Outre les blocs fonctionnels permettant de mettre en œuvre les fonctions de tuner Internet et de tuner récepteur des signaux télédiffusés, le dispositif de l'invention comporte une commande spécifique sous forme notamment d'un bouton-poussoir, ou de l'icône d'un bouton présentée sur un afficheur, marqué par exemple "ACHAT" et dont la fonction est de permettre l'achat impulsif par l'utilisateur d'une musique en cours de diffusion captée par le tuner récepteur.In addition to the functional blocks making it possible to implement the functions of Internet tuner and of tuner receiver of broadcast signals, the device of the invention comprises a specific command in the form in particular of a push button, or of the icon of a button presented on a display, marked for example "PURCHASE" and whose function is to allow the impulsive purchase by the user of music being broadcast received by the receiver tuner.
Cet achat impulsif se déroule de la manière suivante : Étape n° 1 : l'auditeur accordé sur l'une des stations captées par le tuner récepteur souhaite faire l'acquisition d'une plage musicale en cours de diffusion.This impulse purchase takes place in the following way: Step n ° 1: the listener tuned to one of the stations received by the receiver tuner wishes to acquire a musical track being broadcast.
Étape n° 2 : il appuie à cette fin sur le bouton marqué "ACHAT". Étape n° 3 : le dispositif prend alors en compte les coordonnées complètes de la plage en cours de diffusion (les références EAN précitées). Étape n° 4 : l'écran d'affichage du dispositif sollicite alors une confirmation de l'ordre par l'auditeur, par exemple par un message du type "Voulez-vous vraiment acheter la Toccata en ré mineur de J.S. Bach, BWV 915 au prix de 4,50 F ?". Étape n° 5 : deux options sont affichées : "OK" et "Annuler". Étape n° 6 : "OK" ayant été sélectionné par appui sur le bouton, les informations EAN sont transférées pour partie à un centre serveur distant (ci- après appelé "site discographique"), et pour partie dans la mémoire de la carte à microcircuit. Le procédé peut être mis en œuvre de deux manières différentes. Si la station d'émission diffusant les données audio est confondue avec le site central qui effectue les données à télécharger (le site discographique), la communication est bidirectionnelle et le tuner peut afficher directement le prix d'acquisition de l'œuvre choisie en fonction d'une indication de prix transmise par la station d'émission en même temps que les réfé- rences EAN en réponse à la requête. En revanche, si la station d'émission est une station de radiodiffusion émettant de façon classique (transmission unidirectionnelle) et distincte du site discographique, elle ne peut capter ni la requête de l'utilisateur, ni la confirmation du paiement de l'achat. Le dispositif utilisateur captera alors les références EAN émises par cette station d'émission et enverra la requête par Internet vers un site discographique, qui répondra avec un signal indiquant le prix d'achat ; la télétransmission sera ensuite opéré avec ce même site discographique. Dans le cas le plus simple, l'œuvre acquise est identique à celle diffusée et identifiée par la station de télédiffusion.Step 2: To do this, he presses the button marked "PURCHASE". Step 3: the device then takes into account the full coordinates of the range being broadcast (the EAN references mentioned above). Step 4: the display screen of the device then requests confirmation of the order by the listener, for example by a message such as "Do you really want to buy the Toccata in D minor from JS Bach, BWV 915 at the price of 4.50 F? ". Step 5: two options are displayed: "OK" and "Cancel". Step n ° 6: "OK" having been selected by pressing the button, the EAN information is transferred partly to a remote server center (hereinafter called "record site"), and partly to the memory of the card microcircuit. The method can be implemented in two different ways. If the transmitting station broadcasting the audio data is confused with the central site which performs the data to be downloaded (the discographic site), the communication is bidirectional and the tuner can directly display the acquisition price of the work chosen according to a price indication transmitted by the transmitting station at the same time as the EAN references in response to the request. On the other hand, if the transmitting station is a broadcasting station transmitting in the conventional manner (unidirectional transmission) and distinct from the recording site, it cannot receive either the user's request or the confirmation of payment for the purchase. The user device will then pick up the EAN references sent by this transmitting station and send the request over the Internet to a recording site, which will respond with a signal indicating the purchase price; the teletransmission will then be operated with this same record site. In the simplest case, the acquired work is identical to that broadcast and identified by the broadcasting station.
Cependant, surtout dans le cas où la requête est adressée à un site discographique différent de la station d'émission, ce site discographique peut proposer des œuvres différentes, notamment si l'enregistrement identique à l'œuvre identifiée n'est pas disponible, ou ne l'est qu'avec des interprètes différents ou à des dates ou lieux d'enregistrement différents. Le site discographique peut également proposer plusieurs formules différentes d'achat de droits d'écoute des œuvres acquises : débit d'un compte ou imputation sur un abonnement, débit d'une carte prépayée (notamment débit de la carte à microcircuit), etc. L'étape n° 6 de confirmation d'achat peut suivre immédiatement les étapes précédentes, ce qui est propice à une certaine spontanéité de l'achat. Dans certains cas, il peut cependant être utile de différer cette étape de confirmation par rapport aux étapes précédentes. Notamment, l'étude de plusieurs propositions d'achat peuvent nécessiter une concentration qui serait peut commode dans certaines circonstances (l'utilisateur écoute la radio en conduisant un véhicule) ou même impossible lorsque la liaison avec le site discographique n'est pas disponible au moment de l'écoute (le cas typique étant celui de l'écoute de la radio sur un baladeur ou sur une autoradio de véhicule automobile, à moins que l'utilisateur ne dispose d'une liaison de transmission de données par radiotéléphonie).However, especially in the case where the request is addressed to a discographic site different from the transmitting station, this discographic site may offer different works, in particular if the recording identical to the identified work is not available, or only with different interpreters or on different dates or places of recording. The discographic site can also offer several different formulas for purchasing listening rights to the works acquired: debiting an account or charging on a subscription, debiting a prepaid card (in particular debiting the microcircuit card), etc. Step 6 of confirmation of purchase can immediately follow the previous steps, which is conducive to a certain spontaneity of the purchase. In some cases, however, it may be useful to defer this confirmation step from the previous steps. In particular, the study of several purchase proposals may require a concentration which would be may be convenient in certain circumstances (the user listens to the radio while driving a vehicle) or even impossible when the link with the record site is not available time of listening (the typical case being that of listening to the radio on a portable music player or on a car radio, unless the user has a data transmission link by radiotelephony).
Dans ce cas, les références EAN sont mémorisées dans le dispositif pour exploitation ultérieure ; dans le cas où le dispositif comporte un microcircuit, notamment un microcircuit intégré à une carte, les références EAN peuvent être stockées dans la mémoire de ce microcircuit'. Avantageusement, on peut prévoir également d'enregistrer un échantillon de l'œuvre sélectionnée, ce qui facilite l'exploitation ultérieure des références EAN stockées lorsqu'il est nécessaire de choisir entre plusieurs de ces références. Le tuner récepteur de radiodiffusion peut être un élément séparé du tuner Internet. Le tuner récepteur comporte alors ses propres moyens d'affichage et d'écoute ainsi qu'un bouton "ACHAT" OU autre moyen de capture de l'ordre d'enregistrement des références EAN. Dans un mode particulier de réalisation, il est possible de coupler ulté- rieurement les deux tuners pour transmettre la requête au site discographique et télécharger l'œuvre choisie.In this case, the EAN references are stored in the device for later use; in the case where the device comprises a microcircuit, in particular a microcircuit integrated into a card, the EAN references can be stored in the memory of this microcircuit ' . Advantageously, provision may also be made to record a sample of the selected work, which facilitates the subsequent exploitation of the stored EAN references when it is necessary to choose between several of these references. The broadcast receiver tuner can be a separate item from the Internet tuner. The receiver tuner then has its own display and listening means as well as a "PURCHASE" button OR other means of capturing the order of recording of EAN references. In a particular embodiment, it is possible to later couple the two tuners to transmit the request to the recording site and download the chosen work.
Dans un autre mode de réalisation préféré, le microcircuit, notamment sous forme d'une carte à puce, est separable des deux tuners et ces deux tuners comportent des lecteurs aptes à communiquer avec le microcircuit. La carte est alors d'abord installée dans le tuner récepteur ; après capture des références et leur stockage dans la mémoire du microcircuit, la carte est retirée du tuner récepteur et installée dans le lecteur du tuner Internet, qui poursuit le processus en établissant la communication avec le site discographique pour réception de la proposition d'achat élaborée à partir des données enregistrées dans le microcircuit separable et transmises au site discographique.In another preferred embodiment, the microcircuit, in particular in the form of a smart card, is separable from the two tuners and these two tuners include readers capable of communicating with the microcircuit. The card is then first installed in the receiver tuner; after capturing the references and storing them in the microcircuit's memory, the card is removed from the receiver tuner and installed in the reader of the Internet tuner, which continues the process by establishing communication with the recording site for receipt of the elaborate purchase proposal from the data recorded in the separable microcircuit and transmitted to the discographic site.
L'intégration dans un même appareil des deux tuners permet d'utiliser un affichage commun et des moyens d'écoute commun dans le cas d'un tuner recevant des informations diffusées sous forme numérique sur Inter- net, ainsi que dans le cas de tuner récepteur et Internet utilisant des voies de communication différentes.The integration of the two tuners in the same device makes it possible to use a common display and common listening means in the case of a tuner receiving information broadcast in digital form on the Internet, as well as in the case of a tuner receiver and the Internet using different communication channels.
L'utilisation d'un bouton "ACHAT" se révèle particulièrement commode et pratique pour déclencher la capture des références EAN et leur stockage. D'autres moyens peuvent cependant être envisagés : le tuner peut par exemple enregistrer automatiquement un historique des références EAN des œuvres écoutées récemment et, sur demande, présenter ultérieurement une liste pour permettre à l'utilisateur de sélectionner l'œuvre voulue. Le paiement de l'achat peut être effectué par les mêmes procédés que ceux divulgués par les demandes françaises précitées 98 10543 et 98 15377.The use of a "PURCHASE" button is particularly convenient and practical to trigger the capture of EAN references and their storage. Other means can however be envisaged: the tuner can for example automatically record a history of the EAN references of the works listened to recently and, on request, present a list later to allow the user to select the desired work. Payment for the purchase can be made by the same procedures as those disclosed by the aforementioned French applications 98 10543 and 98 15377.
De préférence, le même microcircuit, notamment celui d'une carte à puce, participe au paiement de l'achat et stocke des informations concernant la nature des droits d'écoute achetés. Ceci permet de garantir avec un ni- veau élevé de sécurité le respect des conditions d'achat des droits d'écoute ; cette sécurité est encore renforcée si la même carte effectue également le décryptage de la musique téléchargée et au moins une partie du processus de décompression des données. Dans une variante de mise en œuvre de l'invention, la donnée numérique d'identification est remplacée par un identifiant de canal (par exemple la fréquence de la station FM) et une heure (au sens large, pouvant inclure la date) ; ces informations sont transmises par le moyen de téléchargement/streaming à un serveur, qui consulte une table ("playlist" de la station de radio) indiquant les séquences transmises sur ce canal à cette heure (ce qui suppose une référence chronologique commune, par exemple date et heure GMT), et reconnaît ainsi la séquence à proposer à l'utilisateur. Cette table peut être obtenue soit par une coopération avec le gestionnaire du moyen de télédiffusion qui la transmet au serveur, soit par une écoute du moyen de télédiffusion et l'identification des séquences. Dans tous les cas, la donnée numérique d'identification de séquence (ou l'identifiant de canal et l'heure) peut être conservée dans une mémoire intermédiaire, par exemple une mémoire amovible connectée ultérieurement à un micro-ordinateur relié à Internet ; ce système est avantageusement applicable dans la cas d'une auto-radio pour l'achat de morceaux jugés intéressants. Preferably, the same microcircuit, in particular that of a smart card, participates in the payment of the purchase and stores information concerning the nature of the listening rights purchased. This makes it possible to guarantee, with a high level of security, compliance with the conditions of purchase of listening rights; this security is further enhanced if the same card also performs the decryption of the downloaded music and at least part of the data decompression process. In a variant implementation of the invention, the digital identification data is replaced by a channel identifier (for example the frequency of the FM station) and a time (in the broad sense, which can include the date); this information is transmitted by the download / streaming means to a server, which consults a table ("playlist" of the radio station) indicating the sequences transmitted on this channel at this time (which supposes a common chronological reference, for example date and time GMT), and thus recognizes the sequence to be proposed to the user. This table can be obtained either by cooperation with the manager of the broadcasting means which transmits it to the server, or by listening to the broadcasting means and identifying the sequences. In all cases, the digital sequence identification data (or the channel identifier and the time) can be stored in an intermediate memory, for example a removable memory subsequently connected to a microcomputer connected to the Internet; this system is advantageously applicable in the case of a car radio for the purchase of pieces deemed interesting.
