Description

Transmission d'un contenu multimédia à travers un réseau à destination d'un terminal de télécommunication Transmission of multimedia content through a network to a telecommunications terminal
L'invention concerne le domaine des télécommunications et plus particulièrement un procédé et un serveur pour la transmission d'un contenu multimédia à travers un réseau à destination d'un terminal de télécommunication.The invention relates to the field of telecommunications and more particularly to a method and a server for transmitting multimedia content through a network to a telecommunications terminal.
Il est connu de mettre à disposition un contenu multimédia via un serveur Web. L'utilisateur accède au contenu en se connectant à ce serveur au moyen d'un terminal de télécommunication puis en téléchargeant ce contenu afin d'en prendre connaissance.It is known to provide multimedia content via a web server. The user accesses the content by connecting to this server by means of a telecommunication terminal and then downloading this content in order to become acquainted with it.
Dans le cadre de la mise en œuvre d'un service de diffusion de contenu multimédia associé à un événement particulier, par exemple une vidéo relative à un événement sportif, il est connu d'envoyer un message au terminal de l'utilisateur abonné afin de lui notifier l'occurrence de l'événement et la présence d'un contenu à télécharger. Usuellement le message comprend une URL (Uniform Resource Location) permettant l'accès à ce contenu.In the context of the implementation of a multimedia content broadcasting service associated with a particular event, for example a video relating to a sports event, it is known to send a message to the terminal of the subscribed user in order to notify him of the occurrence of the event and the presence of content to download. Usually the message includes a URL (Uniform Resource Location) allowing access to this content.
Toutefois ce mode de diffusion de contenu est peu commode car il requiert plusieurs actions successives de la part de l'utilisateur: l'utilisateur doit consulter sa messagerie, ouvrir le message reçu, puis sélectionner I1URL contenue dans ce message et enfin établir une connexion à un serveur associé à l'URL sélectionnée.However, this method of broadcasting content is inconvenient because it requires several successive actions on the part of the user: the user must consult his mail, open the received message, then select I 1 URL contained in this message and finally establish a connect to a server associated with the selected URL.
En conséquence, ce mode de diffusion ne permet pas une diffusion en temps réel d'informations puisque la mise à disposition du contenu ne se produit qu'après que l'utilisateur a exécuté ces différentes actions.Consequently, this broadcasting mode does not allow real-time broadcasting of information since the provision of the content only occurs after the user has performed these various actions.
Il apparaît donc un besoin pour une solution de diffusion de contenu multimédia permettant une mise à disposition rapide et simple de tout type de contenu multimédia. Un des buts de l'invention est de remédier à des problèmes et inconvénients de l'état de la technique et/ou d'y apporter des améliorations.There is therefore a need for a solution for broadcasting multimedia content enabling quick and easy provision of any type of multimedia content.

L'invention est décrite dans le contexte de son application à un service de diffusion de contenu multimédia.FIG. 2 represents a flowchart of one embodiment of the method according to the invention. The invention is described in the context of its application to a multimedia content broadcasting service.
Le système de la figure 1 est une représentation simplifiée d'un système de communication pour la mise en œuvre de l'invention. Ce système comprend: un premier réseau RS1 de transmission de données, en l'occurrence le réseau Internet, un deuxième réseau RS2 de transmission de données et de téléphonie, en l'occurrence un réseau mobile, par exemple de type UMTS; un serveur applicatif AS1 ,The system of FIG. 1 is a simplified representation of a communication system for the implementation of the invention. This system comprises: a first data transmission network RS1, in this case the Internet network, a second data transmission and telephony network RS2, in this case a mobile network, for example of the UMTS type; an application server AS1,
- un serveur de contenu multimédia MM1 ,a MM1 multimedia content server,
- une base de données DB, une passerelle GW d'interconnexion entre le réseau RS1 et le réseau RS2, - un terminal mobile MB1 , de type téléphone mobile, un terminal fixe PC1 , de type ordinateur personnel.a database DB, a gateway GW for interconnection between the network RS1 and the network RS2, a mobile terminal MB1, of the mobile telephone type, a fixed terminal PC1, of the personal computer type.
Le serveur de contenu multimédia MM1 est associé à une base de données DB permettant de stocker les différents contenus multimédia à transmettre lors de la mise en œuvre du service. Un contenu multimédia est par exemple un fichier son, une photo, une vidéo, un document texte ou une quelconque combinaison de ces éléments.The multimedia content server MM1 is associated with a database DB for storing the various multimedia contents to be transmitted during the implementation of the service. Multimedia content is for example a sound file, a photo, a video, a text document or any combination of these elements.
Selon l'invention, le contenu multimédia est transmis sous forme de flux téléphonique et/ou télévisuel. On suppose donc que le terminal MB1 est capable de recevoir un tel flux et que le réseau RS2 de transmission de données permet la transmission d'un tel flux. En l'occurrence, un réseau UMTS permet l'établissement de communications téléphoniques ou de communications visiophoniques, et donc l'acheminement de flux téléphoniques et/ou télévisuels (flux audio et/ou vidéo, au sens large). Le terminal utilisé pour la mise en œuvre du service est supposé être un terminal capable de recevoir de telles communications, par exemple un terminal mobile 3G (dit de troisième génération). Un autre type de terminal, fixe ou mobile, ayant des capacités identiques est également utilisable.According to the invention, the multimedia content is transmitted in the form of a telephone and / or television stream. It is therefore assumed that the terminal MB1 is capable of receiving such a stream and that the RS2 data transmission network allows the transmission of such a stream. In this case, a UMTS network allows the establishment of telephone communications or videophone communications, and therefore the routing of telephone and / or television streams (audio and / or video stream, in the broad sense). The terminal used for the implementation of the service is assumed to be a terminal capable of receiving such communications, for example a 3G mobile terminal (said third generation). Another type of terminal, fixed or mobile, with identical capabilities is also usable.
Le serveur de contenu multimédia MM1 comprend un module de communication pour communiquer par messages avec le serveur applicatif AS1. En particulier, lorsqu'un nouveau contenu multimédia est enregistré par le serveur de contenu MM1 et disponible pour une transmission, le module de commande signale au serveur applicatif AS1 la disponibilité de ce nouveau contenu, en lui envoyant un message identifiant et/ou décrivant ce nouveau contenu.The multimedia content server MM1 comprises a communication module for communicating by messages with the application server AS1. In particular, when a new multimedia content is recorded by the content server MM1 and available for transmission, the control module notifies the application server AS1 the availability of this new content, by sending a message identifying and / or describing this new content.
Le serveur applicatif AS1 est un serveur Web proposant un service de diffusion de contenu multimédia.The application server AS1 is a web server offering a service for broadcasting multimedia content.
L'accès au service proposé par ce serveur est possible, de manière connue, par connexion établie à travers le réseau RS1 entre un terminal et ce serveur. Lorsque l'accès au serveur applicatif AS1 s'effectue au moyen d'un terminal mobile, qui comme le terminal mobile MB1 n'accède pas directement au réseau RS1 , la connexion entre le terminal et le serveur est établie de manière connue à travers le réseau RS2, puis à travers la passerelle d'interconnexion GW et enfin le réseau RS1.Access to the service offered by this server is possible, in known manner, by connection established through the network RS1 between a terminal and this server. When access to the application server AS1 is effected by means of a mobile terminal, which like the mobile terminal MB1 does not directly access the network RS1, the connection between the terminal and the server is established in a known manner through the RS2 network, then through the GW interconnection gateway and finally the RS1 network.
Ce même utilisateur U1 est susceptible d'accéder au serveur applicatif AS1 au moyen de son terminal fixe PC1 connecté au réseau RS1. Dans ce cas, la liaison entre le terminal fixe PC1 et le serveur applicatif AS1 est établie via le réseau RS1 sans passer par la passerelle GW1.This same user U1 is likely to access the application server AS1 by means of its fixed terminal PC1 connected to the network RS1. In this case, the connection between the fixed terminal PC1 and the application server AS1 is established via the network RS1 without going through the gateway GW1.
L'accès au service suppose un enregistrement préalable, pour chaque utilisateur U1 , d'un profil utilisateur dans lequel sont spécifiés : le ou les contenus multimédia que l'utilisateur U1 souhaite recevoir, un identifiant du terminal de l'utilisateur U1 vers lequel ces contenus sont à transmettre, etAccess to the service presupposes prior registration, for each user U1, of a user profile in which are specified: the multimedia content or contents that the user U1 wishes to receive, an identifier of the terminal of the user U1 to which these contents are to be transmitted, and
- le mode de déclenchement de la transmission de chacun de ces contenus. L'utilisateur U1 définit son profil et transmet les données associées au serveur applicatif AS1 en se connectant, au moyen du terminal mobile MB1 ou du terminal PC1 , à un site Web géré par le serveur applicatif AS1.the mode of triggering the transmission of each of these contents. The user U1 defines his profile and transmits the data associated with the application server AS1 by connecting, by means of the mobile terminal MB1 or the terminal PC1, to a website managed by the application server AS1.
Le serveur applicatif AS1 comprend notamment un module de gestion de profils utilisateur pour mémoriser, pour chaque utilisateur du service, le ou les contenus multimédia sélectionnés, et pour chaque contenu sélectionné le mode de déclenchement choisi par l'utilisateur pour la transmission de ce contenu ainsi que les dates et heures éventuellement associées.The application server AS1 comprises in particular a user profile management module for storing, for each user of the service, the selected multimedia content (s), and for each selected content, the triggering mode chosen by the user for the transmission of this content as well as as the dates and times possibly associated.
La sélection des contenus que l'utilisateur U1 souhaite recevoir s'effectue par exemple par sélection dans une liste de contenus disponibles ou définis en fonction d'événements à venir. La liste des contenus disponibles est fournie par le serveur applicatif AS1 en fonction, d'une part des contenus disponibles via le serveur de contenu MM1 c'est-à-dire déjà présents dans la base de données DB, d'autre part de contenus qu'il est prévu de générer lors d'événements prédéfinis. Par exemple, l'utilisateur peut choisir de recevoir toutes les vidéos montrant les buts marqués pendant un tournoi de football. Dans ce cas, une vidéo sera générée pour chaque but marqué, cette vidéo étant ensuite stockée dans la base de données DB du serveur de contenu MM1. De cette manière la liste des contenus susceptibles d'être transmis est enrichie dynamiquement, au fur et à mesure que se produisent des événements prédéfinis.The selection of the contents that the user U1 wishes to receive is done for example by selection from a list of available or defined contents of upcoming events. The list of available contents is provided by the application server AS1 based, on the one hand, content available via the content server MM1 that is to say, already present in the database DB, on the other hand content that it is planned to generate during predefined events. For example, the user may choose to receive all videos showing goals scored during a football tournament. In this case, a video will be generated for each goal marked, which video is then stored in the DB database of the content server MM1. In this way the list of contents that can be transmitted is dynamically enriched, as predefined events occur.
Le mode de déclenchement de la transmission d'un contenu est par exemple choisi parmi la liste suivante de modes de déclenchement possibles:The mode of triggering the transmission of a content is for example selected from the following list of possible trigger modes:
- déclenchement à date fixe, c'est-à-dire à occurrence d'une date et heure prédéfinies;- fixed date triggering, that is to say, occurrence of a predefined date and time;
- déclenchement périodique, c'est-à-dire à intervalles de temps réguliers à partir d'une occurrence d'une date et heure de départ prédéfinies;- periodic triggering, that is to say at regular intervals of time from an occurrence of a predefined start date and time;
- déclenchement sur événement prévisible, c'est-à-dire à occurrence d'un événement dont l'heure et la date sont inconnues mais dont l'occurrence est certaine; ce type d'événement permet par exemple d'envoyer un contenu relatif à l'arrivée d'une course cycliste, et ce, quelle que soit l'heure à laquelle celle-ci se termine;- triggering on a predictable event, that is, an occurrence of an event whose time and date are unknown but whose occurrence is certain; this type of event makes it possible, for example, to send a content relating to the arrival of a cycling race, whatever the time at which it ends;
- déclenchement sur événement aléatoire, c'est-à-dire à occurrence d'un événement dont l'heure et la date sont inconnues et dont l'occurrence est aléatoire; ce type d'événement permet par exemple d'envoyer un contenu relatif à un but marqué pendant un match de foot, cet événement étant susceptible de ne pas se produire.- triggering on random event, that is to say, occurrence of an event whose time and date are unknown and whose occurrence is random; this type of event makes it possible, for example, to send content relating to a goal scored during a football match, this event being likely not to occur.
Pour un déclenchement à date fixe, l'utilisateur doit spécifier une date et heure pour la transmission du contenu multimédia sélectionné. Pour un déclenchement périodique, l'utilisateur doit spécifier une date et heure de départ et une périodicité.For a fixed date trigger, the user must specify a date and time for the transmission of the selected media content. For periodic triggering, the user must specify a start date and time and a periodicity.
Pour les autres modes de déclenchement, l'utilisateur n'a pas de date ou heure à spécifier.For other trigger modes, the user does not have a date or time to specify.
Le serveur applicatif AS1 comprend en outre un module de pilotage pour détecter une occurrence d'un événement parmi un ensemble prédéterminé d'événements et pour activer le module d'émission suite à une occurrence d'un tel événement. L'ensemble des événements susceptibles d'être détectés par le serveur applicatif AS1 comprend toutes les dates et heures associées à un mode de déclenchement à date fixe ou périodique, ainsi que les événements associés à une mise à disposition d'un nouveau contenu associé à un mode de déclenchement sur événement prévisible ou un mode de déclenchement sur événement aléatoire.The application server AS1 further comprises a control module for detecting an occurrence of an event from a predetermined set events and to activate the transmission module following an occurrence of such an event. The set of events that can be detected by the application server AS1 includes all the dates and times associated with a fixed or periodic date trigger mode, as well as the events associated with the provision of new content associated with a predictable event trigger mode or a random event trigger mode.
Le serveur applicatif AS1 comprend un module de communication pour générer un appel téléphonique ou visiophonique à destination d'un terminal, c'est-à-dire pour émettre une demande d'établissement d'une liaison téléphonique ou visiophonique à travers le réseau RS1 , et éventuellement à travers un autre réseau RS2, cette liaison devant être établie entre ce serveur applicatif AS1 et un terminal dont le numéro est composé. Cette demande d'établissement de liaison se traduit, de manière connue, par l'émission, par un équipement du réseau RS2 auquel est connecté le terminal destinataire, d'un signal de notification d'appel. Si l'utilisateur de ce terminal destinataire décroche, la liaison est, de manière connue, automatiquement établie.The application server AS1 comprises a communication module for generating a telephone or videophone call to a terminal, that is to say to issue a request to establish a telephone or videophone link through the network RS1, and possibly through another network RS2, this link to be established between this application server AS1 and a terminal whose number is dialed. This link establishment request results, in a known manner, in the transmission, by a device of the network RS2 to which the destination terminal is connected, of a call notification signal. If the user of this destination terminal picks up, the link is, in known manner, automatically established.
La notification de la demande est transmise au terminal accompagnée d'une information relative au contenu multimédia destiné à être transmis. Ceci peut être effectué en utilisant la technologie OIP ("Originating Identity Présentation") qui permet de donner une information sur l'émetteur d'un appel ou toute autre information relative à cet appel. Ceci permet avantageusement de renseigner l'utilisateur du terminal destinataire sur la nature de l'appel et sur le contenu multimédia destiné à être transmis, et ce avant même que la liaison ne soit établie.The notification of the request is transmitted to the terminal accompanied by information relating to the multimedia content to be transmitted. This can be done using OIP ("Originating Identity Presentation") technology which allows to give information on the issuer of a call or other information related to this call. This advantageously makes it possible to inform the user of the destination terminal on the nature of the call and on the multimedia content intended to be transmitted, even before the link is established.
Le module de communication du serveur applicatif AS1 est également conçu pour interrompre une telle liaison.The communication module AS1 application server is also designed to interrupt such a link.
Le serveur applicatif AS1 comprend en outre un module de détection pour détecter si une liaison téléphonique ou visiophonique est effectivement établie suite à l'émission d'une demande d'établissement d'une telle liaison. Le module de détection est également conçu pour détecter une interruption d'une telle liaison. Le module de détection est constitué par exemple par un dispositif de couplage permettant l'analyse de la signalisation d'établissement d'appel émise à travers le réseau RS1 ou RS2 et parvenant au serveur applicatif AS1 à travers une interface d'accès au réseau RS 1. Cette signalisation s'effectue, selon le type de réseau utilisé, soit par envoi de message numérique ou de signaux analogiques, ces signaux étant standardisés de manière à être identifiables et reconnaissables. Le serveur applicatif AS1 comprend enfin un module de transmission de contenu multimédia conçu pour transmettre à travers une liaison téléphonique ou visiophonique un contenu sous forme d'un flux téléphonique et/ou télévisuel. En d'autres termes, le contenu est transmis sous forme d'un flux continu (en "streaming" selon la terminologie anglo-saxonne) de telle sorte que ledit contenu soit audible et/ou visualisable par un utilisateur du terminal lorsque la liaison téléphonique ou visiophonique est établie.The application server AS1 further comprises a detection module for detecting whether a telephone or videophone link is actually established following the transmission of a request for establishment of such a link. The detection module is also designed to detect an interruption of such a link. The detection module is constituted for example by a coupling device for analyzing the call setup signaling transmitted through the network RS1 or RS2 and reaching the application server AS1 through an access interface to the network RS 1. This signaling is effected, depending on the type of network used, either by sending digital message or analog signals, these signals being standardized so as to be identifiable and recognizable. The application server AS1 finally comprises a multimedia content transmission module designed to transmit through a telephone or videophone link a content in the form of a telephone and / or television stream. In other words, the content is transmitted in the form of a continuous stream (in "streaming" according to the English terminology) so that said content is audible and / or viewable by a user of the terminal when the telephone link or videophone is established.
L'invention se prête à d'autres modes de réalisation. En particulier, les fonctions mises en œuvre par le serveur applicatif AS1 et le serveur de contenu MM1 peuvent être mises en œuvre par un seul et même serveur. Une autre répartition des fonctions entre ces deux serveurs est également envisageable.The invention lends itself to other embodiments. In particular, the functions implemented by the application server AS1 and the content server MM1 can be implemented by a single server. Another distribution of functions between these two servers is also possible.
Le module de transmission de contenu multimédia peut par exemple être intégré au serveur de contenu MM1.The multimedia content transmission module may for example be integrated with the content server MM1.
Les étapes S100 à S150 du procédé selon l'invention sont décrites plus en détail par référence à la figure 2. Ce procédé est mis en œuvre par le serveur applicatif AS1.The steps S100 to S150 of the method according to the invention are described in more detail with reference to FIG. 2. This method is implemented by the application server AS1.
A l'étape S100 initiale, le module de pilotage du serveur applicatif AS1 est actif en vue de la détection d'un événement parmi un ensemble prédéfinis d'événements. En cas de détection d'un de ces événements, l'étape S110 suivante est exécutée.In the initial step S100, the control module of the application server AS1 is active for the detection of an event from a predefined set of events. If one of these events is detected, the next step S110 is executed.
A l'étape S110, en cas de détection d'une occurrence d'un événement parmi l'ensemble d'événements à détecter, le module de pilotage interroge le module de gestion de profil pour déterminer, en fonction de l'événement détecté, quel est le contenu multimédia à transmettre et à quel terminal ce contenu doit être transmis. On suppose dans la suite que ce terminal est le terminal mobile MB1.In step S110, if an occurrence of an event is detected among the set of events to be detected, the control module interrogates the profile management module to determine, as a function of the detected event, what is the multimedia content to be transmitted and to which terminal this content must be transmitted. It is assumed in the following that this terminal is the mobile terminal MB1.
A l'étape S120, le module de communication du serveur applicatif AS1 génère un appel à destination du terminal identifié à l'étape S110. Puis le module de détection est activé afin de détecter un établissement effectif de la liaison de communication, téléphonique ou visiophonique, avec le terminal mobile MB1. En cas d'établissement effectif de la liaison de communication, c'est-à-dire si l'utilisateur du terminal mobile MB1 décroche, l'étape S130 suivante est exécutée. Dans le cas contraire, le procédé se termine.In step S120, the communication module of the application server AS1 generates a call to the terminal identified in step S110. Then the detection module is activated to detect an effective establishment of the communication link, telephone or videophone, with the mobile terminal MB1. In case of effective establishment of the communication link, that is to say if the user of the mobile terminal MB1 picks up, the next step S130 is executed. Otherwise, the process ends.
A l'étape S130, le module de transmission du serveur applicatif AS1 est activé suite à un établissement effectif de la liaison de communication et débute la transmission du contenu multimédia sous forme d'un flux téléphonique et/ou télévisuel. Le module de détection reste actif pendant cette transmission en vue de détecter une éventuelle coupure de la liaison de communication. En cas de détection d'une coupure ou interruption de la communication, c'est-à-dire dans le cas où l'utilisateur du terminal mobile MB1 raccroche, le module de transmission interrompt la transmission du contenu multimédia et le procédé se termine. Dans le cas contraire, l'étape S140 suivante est exécutée.In step S130, the transmission module of the application server AS1 is activated following an effective establishment of the communication link and begins transmitting the multimedia content in the form of a telephone and / or television stream. The detection module remains active during this transmission in order to detect a possible break in the communication link. In case of detection of a cut or interruption of the communication, that is to say in the case where the user of the mobile terminal MB1 hangs up, the transmission module interrupts the transmission of the multimedia content and the process ends. Otherwise, the next step S140 is executed.
A l'étape S140, le module de transmission du serveur applicatif AS1 poursuit la transmission jusqu'à ce que le contenu multimédia soit transmis dans son intégralité.In step S140, the transmission module of the application server AS1 continues the transmission until the multimedia content is transmitted in its entirety.
Lorsque ledit contenu a été intégralement transmis, le module de communication interrompt, sur commande du module de transmission, la liaison de communication établie.When said content has been fully transmitted, the communication module interrupts, on command of the transmission module, the established communication link.
En complément du mode de réalisation décrit ci-dessus, il peut être prévu que le serveur applicatif AS1 remplisse également les fonctions de serveur de messagerie réseau. Dans ce cas, le ou les contenus multimédia sont transmis à l'utilisateur à travers une liaison téléphonique ou visiophonique, établie entre le serveur et le terminal de l'utilisateur, cette liaison étant dans ce cas établie à l'initiative de l'utilisateur du terminal.In addition to the embodiment described above, it can be expected that the application server AS1 also performs the functions of network messaging server. In this case, the multimedia content (s) are transmitted to the user via a telephone or videophone link established between the server and the user's terminal, this connection being in this case established on the initiative of the user. of the terminal.
Le processus se déroule par exemple comme suit: - le serveur reçoit une notification de demande d'établissement d'une liaison téléphonique ou visiophonique avec un terminal,The process takes place for example as follows: the server receives a request notification for establishing a telephone or videophone link with a terminal,
- lorsque le terminal émetteur de l'appel est un terminal autorisé à accéder au service, le serveur accepte ladite demande (c'est-à-dire décroche), la liaison étant alors établie automatiquement, - le serveur transmet au moins une partie d'un contenu multimédia déjà transmis à ce terminal ou auquel l'utilisateur est abonné, à travers la liaison nouvellement établie, toujours sous forme d'un flux téléphonique et/ou télévisuel.when the terminal transmitting the call is a terminal authorized to access the service, the server accepts said request (that is to say, picks up), the link then being established automatically, the server transmits at least a portion of the call; multimedia content already transmitted to this terminal or to which the user is subscribed, through the newly established link, always in the form of a telephone and / or television stream.
L'invention est applicable à la transmission de tout type de contenu multimédia et à tout type de terminal de télécommunication. Elle simplifie considérablement pour l'utilisateur le mode d'accès au contenu multimédia. The invention is applicable to the transmission of any type of multimedia content and to any type of telecommunication terminal. It greatly simplifies the user's access to the multimedia content.
