Description

Procédé permettant la mise en œuyre de la vidéo enrichie sur les terminaux mobiles Method for implementing enriched video on mobile terminals
L'invention a trait au domaine des télécommunications, et plus précisément à Ia diffusion de vidéo sur les terminaux mobiles.The invention relates to the field of telecommunications, and more specifically to the broadcasting of video on mobile terminals.
Si les réseaux de mobiles de deuxième génération (2G) ont introduit Ia technologie numérique dans les communications sans fil, Ia troisième génération (3G) - mise en œuvre notamment par la norme UMTS (Universal Mobile Télécommunications System) - assure la convergence des réseaux fixes et des réseaux de mobiles en intégrant à ces derniers les services de communication jusque là réservés aux réseaux fixes, grâce notamment à des débits accrus via l'interface air (jusqu'à 2 Mbit/s). Parmi les services supportés figurent notamment (outre la voix) l'audio, la vidéo, le texte et le graphique, c'est-à-dire les éléments essentiels des applications multimédia. Parallèlement, les terminaux mobiles ont vu leur puissance augmenter, et se comportent désormais comme des ordinateurs standards, qui peuvent mettre en œuvre non seulement des applications persistantes - qui se déroulent sur le terminal - mais également des applications non persistantes - qui se déroulent sur un serveur distant, le terminal n'effectuant que les opérations de restitution, tel que l'affichage dans les applications vidéo (Cf. Pujolle, Les Réseaux, éd. 2008, Chap.43, pp.1004-1012).If second generation mobile networks (2G) have introduced digital technology in wireless communications, the third generation (3G) - implemented in particular by UMTS (Universal Mobile Telecommunications System) - ensures the convergence of fixed networks and mobile networks by integrating with them the communication services previously reserved for fixed networks, thanks in particular to increased data rates via the air interface (up to 2 Mbit / s). Supported services include (in addition to voice) audio, video, text, and graphics, which are essential elements of multimedia applications. At the same time, mobile devices have increased in power, and now behave like standard computers, which can implement not only persistent applications - which take place on the terminal - but also non-persistent applications - which take place on a network. remote server, the terminal performing only the rendering operations, such as the display in video applications (see Pujolle, Networks, 2008 edition, Chap.43, pp.1004-1012).
Une application prometteuse des réseaux 3G est la diffusion bidirectionnelle de contenus vidéo numériques, effectuée en continu (streaming) et en direct ou en léger différé.A promising application of 3G networks is the two-way streaming of digital video content, performed continuously (streaming) and live or lightly delayed.
L'un des attraits - et l'une des difficultés - de ce type de service est l'inclusion, dans le contenu diffusé, de fonctionnalités interactives permettant au spectateur de transmettre des réactions au contenu (vote, partage d'opinion, envoi de messages à l'attention du diffuseur, demande de services complémentaires telle que la commande de sonneries personnalisées, etc.). Ces fonctionnalités interactives sont attrayantes car elles donnent au spectateur l'opportunité d'influer sur la diffusion. Elles sont toutefois difficiles à mettre en œuvre en temps réel en raison des délais inhérents à la diffusion dans les réseaux de mobiles, les débits permis par la 3G n'évitant pas des baisses ponctuelles du taux de transfert, ou même la perte momentanée de la liaison. En définitive, le champ des fonctionnalités interactives est relativement restreint. En particulier, une véritable navigation Web à partir du contenu diffusé n'est, à ce jour, pas réalisable.One of the attractions - and one of the difficulties - of this type of service is the inclusion, in the broadcast content, of interactive functionalities allowing the viewer to transmit reactions to the content (vote, opinion sharing, sending of broadcaster messages, request for additional services such as ordering personalized ringtones, etc.). These interactive features are attractive because they give the viewer the opportunity to influence the broadcast. However, they are difficult to implement in real time because of the delays inherent in broadcasting in mobile networks, the bit rates enabled by 3G not avoiding occasional drops in the transfer rate, or even the momentary loss of the transmission rate. link. Ultimately, the field of interactive features is relatively small. In particular, a real web browsing from the content broadcast is, to date, not feasible.
L'invention vise notamment à améliorer l'interactivité dans les services de diffusion bidirectionnelle de contenus vidéo numériques.The invention aims in particular to improve the interactivity in the bidirectional broadcast services of digital video content.
A cet effet, l'invention propose, suivant un premier aspect, un procédé de fourniture d'un contenu vidéo, comprenant les opérations suivantes :For this purpose, the invention proposes, in a first aspect, a method for providing a video content, comprising the following operations:
- établissement d'une session vidéo entre un terminal mobile et un système de communication distant ; fourniture au terminal, par le système de communication, d'une vidéo enrichie d'un ou plusieurs marqueurs incrustés dans Ia vidéo ; activation à partir du terminal d'au moins un marqueur pendant Ia session vidéo ;establishing a video session between a mobile terminal and a remote communication system; providing the terminal, via the communication system, with a video enriched with one or more markers embedded in the video; activating from the terminal at least one marker during the video session;
- envoi par le système de communication au terminal mobile d'un message textuel (par exemple un SMS ou un courrier électronique) comprenant un signet associé au marqueur activé.sending the communication system to the mobile terminal a text message (for example an SMS or an electronic mail) comprising a bookmark associated with the activated marker.
Suivant un mode de réalisation, ce signet comprend au moins une adresse d'une page Web. Plus précisément, le signet est par exemple associé à un hyperlien pointant sur ladite page Web.According to one embodiment, this bookmark comprises at least one address of a web page. More specifically, the bookmark is for example associated with a hyperlink pointing to said web page.
Quant au marqueur incrusté dans la vidéo, il s'agit par exemple d'un objet visuel.As for the marker embedded in the video, it is for example a visual object.
L'activation du marqueur peut être effectuée au moyen d'une commande à partir d'un clavier du terminal, la reconnaissance de la commande étant de préférence effectuée, au sein du système de communication, par analyse fréquentielle.Activation of the marker can be effected by means of a command from a keyboard of the terminal, the recognition of the command being preferably carried out, within the communication system, by frequency analysis.
Suivant un deuxième aspect, l'invention propose un système de communication comprenant : un serveur média, propre à établir une session vidéo avec un terminal mobile ;According to a second aspect, the invention proposes a communication system comprising: a media server, suitable for establishing a video session with a mobile terminal;
- un serveur d'applications vidéo, relié au serveur média et sur lequel est implémentée une application de vidéo enrichie configurée pour inclure dans une vidéo un ou plusieurs marqueurs ; un serveur de messagerie, relié au serveur d'applications vidéo, programmé, sur commande du serveur d'applications vidéo, pour transmettre au terminal un message textuel en lien avec un marqueur activé depuis le terminal, et éventuellement une base de données reliée au serveur d'applications vidéo, dans laquelle sont mémorisés lesdits marqueurs.a video application server, connected to the media server and on which is implemented an enriched video application configured to include in one video one or more markers; a messaging server, connected to the video application server, programmed, on command of the video application server, to transmit to the terminal a text message in connection with a tag activated from the terminal, and optionally a database connected to the video application server, in which said markers are stored.
D'autres objets et avantages de l'invention apparaîtront à la lumière de la description faite ci-après en référence au dessin annexé qui illustre une architecture réseau et un procédé de communication conformes à l'invention.Other objects and advantages of the invention will become apparent in the light of the description given hereinafter with reference to the accompanying drawing which illustrates a network architecture and a communication method according to the invention.
L'architecture réseau 1 représentée comprend un terminal 2 mobile (téléphone mobile, PDA communicant ou Smartphone), relié, via l'interface air, à un système 3 de communication comprenant un serveur média 4, qui assure l'établissement de sessions médias avec le terminal 2, un serveur 5 d'applications vidéo, relié au serveur média 4 et sur lequel est implémentée une application de vidéo enrichie, une base de données 6 dans laquelle sont mémorisés des objets visuels, reliée ou intégrée au serveur 5 d'applications vidéo, ainsi qu'un serveur 7 de messagerie relié au serveur 5 d'applications vidéo.The represented network architecture 1 comprises a mobile terminal 2 (mobile telephone, communicating PDA or Smartphone), connected, via the air interface, to a communication system 3 comprising a media server 4, which ensures the establishment of media sessions with the terminal 2, a video application server 5, connected to the media server 4 and on which is implemented an enriched video application, a database 6 in which are stored visual objects, connected or integrated with the application server 5 video, as well as a mail server 7 connected to the video application server 5.
Le terminal est équipé d'un écran 8 permettant l'affichage de vidéos, d'un clavier 9 permettant à l'utilisateur d'introduire des commandes, d'un haut-parleur permettant une restitution sonore audible à distance (c'est-à-dire lorsque le terminal 2 est tenu à bout de bras) ou d'une oreillette pour une écoute discrète.The terminal is equipped with a screen 8 for displaying videos, a keyboard 9 allowing the user to introduce commands, a loudspeaker allowing an audible sound reproduction at a distance (ie that is, when the terminal 2 is held at arm's length) or an atrium for discreet listening.
Le serveur média 4 et le terminal mobile 2 sont configurés pour établir entre eux des sessions médias (par exemple suivant le protocole RTP ou H324m), permettant notamment l'échange de données vidéo, notamment dans le cadre de la fourniture d'un service de vidéo à la demande.The media server 4 and the mobile terminal 2 are configured to establish between them media sessions (for example according to the RTP or H324m protocol), notably allowing the exchange of video data, in particular as part of the provision of a video service. video on demand.
Les protocoles de transfert de données utilisés seront choisis de préférence pour obtenir une vitesse de transmission des données maximale, afin de minimiser le temps de réponse à des éventuelles interactions.The data transfer protocols used will preferably be chosen to obtain a maximum data transmission rate, in order to minimize the response time to possible interactions.
Une session média est d'abord établie (100) suivant un protocole temps réel (par exemple RTP ou H324m) entre le terminal 2 et le système 3 de communication, et plus précisément entre le terminal 2 (à l'initiative de celui-ci) et le serveur média 4. Cette session est bidirectionnelle, et comprend la transmission de données vidéo (et audio) en temps réel, avec codage des données sortantes (à l'entrée de l'interface air) et décodage des données entrantes (à la sortie de l'interface air) effectués par le terminal 2.A media session is first established (100) according to a real-time protocol (for example RTP or H324m) between the terminal 2 and the communication system 3, and more specifically between the terminal 2 (on the initiative of the latter This session is bidirectional, and includes the transmission of video (and audio) data in real time, with coding of outgoing data (at the input of the air interface) and decoding incoming data (at the output of the air interface) made by the terminal 2.
Le serveur média 4 signale alors sans délai (110) au serveur 5 d'applications vidéo l'ouverture de cette session média, pour commander l'ouverture de l'application de vidéo enrichie, au moyen de laquelle des marqueurs, extraits de la base 6 de données, sont ajoutés à la vidéo diffusée. Ces marqueurs se présentent sous la forme d'objets visuels (textes pouvant être agencés ou non sous forme de menus, icônes, images - tels que logos -, animations) apparaissant en incrustation, éventuellement de manière localisée (par exemple en lien avec un produit) et temporaire.The media server 4 then immediately signals (110) to the video application server 5 the opening of this media session, to control the opening of the enriched video application, by means of which markers, extracted from the base 6 of data, are added to the broadcast video. These markers are in the form of visual objects (texts that can be arranged or not in the form of menus, icons, images - such as logos -, animations) appearing in incrustation, possibly in a localized manner (for example in connection with a product ) and temporary.
Le flux de vidéo enrichie est transmis par le serveur 5 d'applications vidéo au serveur 4 média (120), compressé en temps réel au format d'échange précédemment employé (H.263, MPEG-4, H.264), et relayé (130) au terminal 2, qui en assure localement la décompression et la restitution.The enriched video stream is transmitted by the video application server 5 to the 4 media server (120), compressed in real time in the exchange format previously used (H.263, MPEG-4, H.264), and relayed (130) Terminal 2, which provides local decompression and restitution.
Dès l'affichage d'un marqueur sur le terminal, et pendant une durée prédéterminée (par exemple confondue avec la durée d'affichage du marqueur), la possibilité est offerte à l'utilisateur d'activer le marqueur, notamment au moyen d'une commande vocale ou manuelle, par exemple par l'intermédiaire de touches du clavier 9, qui peut être réel ou virtuel.As soon as a marker is displayed on the terminal, and for a predetermined duration (for example, coinciding with the duration of display of the marker), the possibility is offered to the user to activate the marker, in particular by means of a voice or manual command, for example by means of keys of the keyboard 9, which can be real or virtual.
L'activation est transmise (140) par le terminal 2, au cours de la session média, au serveur média 4, qui les relaye (150) au serveur 5 d'application vidéo. Cette activation est par exemple commandée par l'appui sur une touche du clavier 9, notamment parmi les touches du pavé numérique. L'appui sur la touche provoque l'envoi par le terminal 2 d'un signal de fréquence DTMF (Dual Tone Multi-Frequency) au serveur 4 média, qui le relaye au serveur 5 d'applications vidéo. Celui- ci effectue une analyse fréquentielle du signal dont est déduite la commande activée par le terminal 2, et la reconnaissance subséquente (par exemple au moyen d'un recoupement avec la plage horaire dans laquelle a été effectuée la commande) du marqueur ainsi activé. En variante, l'activation peut être commandée par la détection d'un mouvement particulier du terminal 2 (lequel sera à cet effet équipé de capteurs), ou encore par reconnaissance d'une image capturée et reconnue par le terminai 2. Le serveur 5 d'applications vidéo commande alors l'envoi au terminal, via le serveur de messagerie (160 et 170), d'un message textuel (SMS ou courriel, suivant les fonctionnalités du terminal) contenant un signet en lien avec le marq ueur activé. Ce signet comprend l'adresse ou URL (U niform Resource Locator) d'une page Web sur laq uelle l'utilisateur pourra naviguer ultérieurement à partir du terminal 2 au moyen d 'un navigateur ou d 'un micronavigateur utilisant un protocole d'échange tel q ue HTTP (HyperText Transfer Protocol) ou WAP (Wireless Application Protocol). L'URL peut être associé à un lien hypertexte (hyperlien) cliquable, pointant vers la page Web visée et commandant l'ouverture du navigateur et le chargement de la page.The activation is transmitted (140) by the terminal 2, during the media session, to the media server 4, which relay (150) to the video application server 5. This activation is for example controlled by pressing a key on the keyboard 9, in particular among the keys of the numeric keypad. Pressing the key causes the terminal 2 to send a DTMF frequency signal (Dual Tone Multi-Frequency) to the 4-media server, which relays it to the video application server 5. This performs a frequency analysis of the signal from which is deduced the command activated by the terminal 2, and the subsequent recognition (for example by means of overlapping with the time range in which the control was performed) of the marker thus activated. Alternatively, the activation can be controlled by the detection of a particular movement of the terminal 2 (which will be equipped with sensors for this purpose), or by recognition of an image captured and recognized by the terminal 2. The video application server 5 then orders the sending to the terminal, via the mail server (160 and 170), of a text message (SMS or email, depending on the functionality of the terminal) containing a bookmark in connection with the mark. activated. This bookmark includes the address or URL (U niform Resource Locator) of a web page on which the user can navigate later from the terminal 2 by means of a browser or a micronavigator using an exchange protocol. such as HTTP (HyperText Transfer Protocol) or WAP (Wireless Application Protocol). The URL can be associated with a clickable hyperlink (hyperlink), pointing to the targeted web page and controlling the opening of the browser and the loading of the page.
L'utilisation du signet n'est toutefois pas limitée à la navigation, et l'utilisateur pourra utiliser les fonctions de bases du terminal 2 pour, notamment, sauvegarder le signet directement sur son terminal 2, ou à distance sur un serveur du réseau 1 pour une utilisation ultérieure depuis tout terminal pouvant être connecté à ce serveur, ou encore le transférer à destination d'un tiers (par exemple identifié en tant que contact dans un répertoire du terminal 2).The use of the bookmark is however not limited to navigation, and the user can use the basic functions of the terminal 2 to, in particular, save the bookmark directly on its terminal 2, or remotely on a network server 1 for later use from any terminal that can be connected to this server, or to transfer it to a third party (for example identified as a contact in a directory of the terminal 2).
Le procédé, et l'architecture qui viennent d'être décrits, permettent aux utilisateurs bénéficiant de services de diffusion de contenus vidéo, et notamment de vidéo à la demande, de naviguer directement à partir de signets en lien avec le contenu diffusé. L'utilisateur économise ainsi une phase de recherche préalable de sites ou pages Web en lien avec des objets visualisés dans la vidéo. The method and the architecture described above enable users benefiting from video content broadcasting services, and in particular video-on-demand services, to browse directly from bookmarks in connection with the content broadcast. The user thus saves a prior search phase of sites or web pages in connection with objects viewed in the video.
