Abstract
The present invention is a system capable of automating the sequencing and the enrichment of a linear audiovisual program or stream of images of any kind (television programs, films, documentaries, series, or any other audiovisual or educational programs). The method and the device consist of a smart video platform giving users access to additional content, services and functionalities for content navigation and layout, searching, sharing and e-commerce in relation to the content of the video. The audiovisual content and user experience are thus enriched. A powerful analysis capability allows this system to collect a high number of metadata on the basis of which the video content is able to be enriched and sequenced. These metadata are synchronized, and the placement of additional content and sequencing may thus be positioned with very high accuracy. The software, which we call the Editor, makes it possible to run through a video stream frame by frame, to adjust the metadata that are automatically generated, to add data and/or functional objects and to place them at chosen times. The interface of this system is formed of two parts, the first designed for the addition, editing and management of the content, the second being used to create and label sequences (chapters), marking points and/or functional objects. It is also used to place content on the timeline. The representation of the data is therefore generated using this Editor or through automatic detection. Finally, a video reader or "player" makes it possible to read the resulting video enriched with its associated data and functions. Under these conditions, this is a module that allows the reader to be included in a third-party application offering consumers an enriched audiovisual experience. It is either autonomous or remains in the universe and the ecosystem of audiovisual rights holders and broadcasters.

Présentation de l'invention Audiovisual soundtrack and its broadcasters. Presentation of the invention
La présente invention dotée d'un forte capacité d'analyse permet de détecter automatiquement un grand nombre d'éléments déterminants permettant la collecte de métadonnées en rapport avec le contenu du moment analysé. Les métadonnées sont synchronisées avec le contenu. Pour cela, toutes les trames d'une vidéo sont analysées, 1 seconde de vidéo correspond à un nombre de trames allant de 25 à 30 trames. A titre d'exemple, s'il est détecté qu'une personnalité apparaît sur la 23ème trame de la 5ème seconde de la vidéo, il est alors possible d'attacher des informations complémentaires au sujet de cette personnalité à partir du timecode 00 :00 :05 :23. The present invention, endowed with a strong analytical capacity, makes it possible to automatically detect a large number of determining elements allowing the collection of metadata relating to the content of the moment analyzed. The metadata is synchronized with the content. For this, all the frames of a video are analyzed, 1 second of video corresponds to a number of frames ranging from 25 to 30 frames. For example, if it is detected that a personality appears on the 23rd frame of the 5th second of the video, it is then possible to attach additional information about this personality from the 00: 00 timecode : 05: 23.
La présente invention concerne le premier pilier de la plateforme, laquelle a pour objectif, par l'enrichissement de métadonnées, de simplifier, en automatisant au maximum, l'ajout de contenus et/ou d'éléments interactifs à un programme audio-visuel. The present invention relates to the first pillar of the platform, the objective of which, by enriching metadata, is to simplify, by automating as much as possible, the addition of content and / or interactive elements to an audio-visual program.
Ce système automatisé est capable d'analyser puis de transformer un programme audiovisuel linéaire ou flux d'images de toute nature (émissions de TV, films, documentaires ...) en un programme audiovisuel interactif consultable sur téléphone mobile, tout écran ou appareil connecté notamment, tablette, Apple TV, Android TV, et/ou smart TV. This automated system is capable of analyzing and then transforming a linear audiovisual program or image stream of any kind (TV shows, films, documentaries, etc.) into an interactive audiovisual program that can be viewed on a mobile phone, any screen or connected device. in particular, tablet, Apple TV, Android TV, and / or smart TV.
Son interface, tout en parcourant un flux vidéo trame par trame, grâce à des algorithmes procédant par extraction, se compose de deux parties, la première destinée à l'ajout, l'édition et la gestion des contenus d'origine, quelle qu'en soit la source interne ou externe, enrichi d'informations ou de fonctionnalités interactives, la seconde servant à la création et à la labélisation de chapitres, séquences événements ou points de marquage étant des contenus éditoriaux contextuels et pertinents. Elle sert également au placement de ces contenus et/ou objets fonctionnels et l'enrichissement de métadonnées.
Des indices audio ou visuels, les métadonnées, permettent d'organiser le séquençage, premier découpage suite à la détection d'indices audio ou visuels de la vidéo, puis de les ajuster et de les affiner à partir des indices ou scènes de la vidéo pour parvenir à une thématique ou une interactivité partielle. Its interface, while browsing a video stream frame by frame, thanks to algorithms proceeding by extraction, is composed of two parts, the first intended for the addition, the edition and the management of the original contents, whatever. either the internal or external source, enriched with information or interactive features, the second used for the creation and labeling of chapters, event sequences or marking points being contextual and relevant editorial content. It is also used for the placement of this content and / or functional objects and the enrichment of metadata. Audio or visual cues, metadata, make it possible to organize the sequencing, the first cutting following the detection of audio or visual cues from the video, then to adjust and refine them from the cues or scenes of the video to achieve a thematic or partial interactivity.
L'Éditeur permet ensuite de parcourir un flux vidéo trame par trame, de vérifier les résultats de l'analyse automatique, d'ajouter des données et de les placer à des temps choisis. The Editor then allows you to step through a video stream frame by frame, check the results of automatic analysis, add data and place it at selected times.
Ces contenus enrichis sont intégrés à la vidéo initiale et reformatés pour obtenir une expérience d'utilisateur personnalisée. This enriched content is integrated into the initial video and reformatted to achieve a personalized user experience.
La création de chapitres consiste à indexer le contenu d'une vidéo dans le but de la parcourir d'une manière non linéaire comme le permettrait le découpage de chapitres fourni sur un support DVD ou la création de liste de lecture regroupant seulement les séquences pertinentes de plusieurs vidéos sous une liste contextuelle. Cela permet également de se situer et de naviguer temporellement durant la lecture du flux. De plus, l'ajout de métadonnées à ces chapitres offre la possibilité d'effectuer des requêtes de recherche au sein même de la vidéo et non plus simplement que sur le titre des fichiers. Chapter creation consists of indexing the content of a video with the aim of browsing it in a non-linear way as would be possible by cutting chapters provided on DVD media or by creating a playlist grouping together only the relevant sequences of the video. multiple videos under a pop-up list. This also makes it possible to locate and navigate temporally during the playback of the stream. In addition, adding metadata to these chapters offers the possibility of performing search queries within the video itself and not just on the title of the files.
Ce procédé d'indexation et de séquençage est illustré dans la [Fig.l] This indexing and sequencing process is illustrated in [Fig.l]
Cette technologie permettra d'analyser et de transformer des vidéos accessibles au public, en direct ou en temps différé, provenant de tout moteur hypertexte ou de recherche, de tout contenu quel qu'en soit l'origine, de bases de données de tout type...
Les contenus à ajouter peuvent être de différents types et sont définis lors de la création des modèles qui sont à l'expérience utilisateur souhaité, lesquels peuvent différer en fonction du format (Film, Magazine, Documentaire) mais aussi du programme proprement dit : il peut s'agir à titre d'exemples de biographies, d'extraits vidéo (bande annonce, clip musical extrait, archive d'émissions déjà diffusés...), ou encore de fonctionnalités d'achat pour la vente de places de concerts, de livres, ou autres. This technology will make it possible to analyze and transform videos accessible to the public, live or in deferred time, coming from any hypertext or search engine, from any content whatever its origin, from databases of any type. ... The contents to be added can be of different types and are defined during the creation of the models which are to the desired user experience, which can differ depending on the format (Film, Magazine, Documentary) but also on the program itself: it can These may be examples of biographies, video extracts (trailer, musical clip extract, archive of programs already broadcast ...), or even purchasing features for the sale of concert tickets, books, or others.
Le résultat est ensuite consultable depuis une application (téléphone mobile, tablette, smart TV, TV OS, site web ou tout écran connecté à internet) permettant de bénéficier de l'expérience enrichie et de consulter les données ajoutées. The result can then be viewed from an application (mobile phone, tablet, smart TV, TV OS, website or any screen connected to the Internet) allowing users to benefit from the enriched experience and consult the added data.
Le dispositif consiste en une plateforme Smart -Vidéo qui comprend, d'une part, un éditeur permettant d'éditer, de publier, de partager, de donner accès à des contenus enrichis, d'autre part de générer un fichier de description temporelle de métadonnées synchronisées, et enfin un lecteur vidéo permettant d'utiliser la Smart-Vidéo. The device consists of a Smart -Video platform which includes, on the one hand, an editor making it possible to edit, publish, share, and provide access to enriched content, on the other hand to generate a temporal description file of synchronized metadata, and finally a video player for using Smart-Video.
Les métadonnées sont accessibles depuis des codes et des fonctionnalités (API, SDK) rendant le lecteur vidéo remplaçable et le dispositif compatible avec tout autre lecteur ou plateforme technologique de manière interopérable. The metadata are accessible from codes and functionalities (API, SDK) making the video player replaceable and the device compatible with any other player or technological platform in an interoperable manner.
Dans ces conditions, le procédé automatise un maximum les actions qui étaient jusqu'alors effectuées par l'intervention d'un être humain capable de visualiser et de comprendre le sens éditorial d'une vidéo. Il en est ainsi des actions suivantes :Under these conditions, the method automates as much as possible the actions which were until then carried out by the intervention of a human being capable of visualizing and understanding the editorial meaning of a video. This is the case for the following actions:
- visionnage d'un flux vidéo « timeline » ; - viewing of a “timeline” video stream;
- identification d'un passage pouvant être augmenté, enrichi d'informations ou de fonctionnalités interactives ; - identification of a passage that can be increased, enriched with information or interactive features;
- ajout de contenu et de données en rapport avec le passage identifié ;
- division en chapitres, séquençage, marquage ; - addition of content and data related to the identified passage; - division into chapters, sequencing, marking;
- placement de modèle temporel de contenus, d'objets interactifs et/ou fonctionnels « vidéo événement » - placement of a temporal model of content, interactive and / or functional “video event” objects
- association d'un modèle de « vidéo événement » à un des contenus gérés par la base de données. - association of a “video event” model with one of the contents managed by the database.
Aussi la plateforme est capable de détecter automatiquement des chapitres et des évènements vidéo, audio ou multimédia, à partir de solutions d'Apprentissage Profond (« deeplearning ») ou réseaux neuronaux mais également à partir d'algorithmes du domaine du traitement du signal, et de créer seul un « vidéo événement » à partir de la vidéo initiale. Elle peut aussi ajouter des « vidéo événements » d'autres types en fonction du contexte, du contenu et de la narration détectée. Also the platform is capable of automatically detecting chapters and video, audio or multimedia events, from Deep Learning solutions ("deeplearning") or neural networks but also from algorithms in the field of signal processing, and to create a "video event" from the initial video on your own. It can also add “video events” of other types depending on the context, content and narration detected.
La solution de détection automatique, plus communément appelée « moteur d'automatisation » se divise en 2 blocs, l'un destiné au découpage de la vidéo en chapitres, l'autre aux placements de contenus interactifs. The automatic detection solution, more commonly known as the “automation engine” is divided into 2 blocks, one intended for splitting the video into chapters, the other for placing interactive content.
Elle peut être représentée selon le schéma décrit dans la [Fig.2] It can be represented according to the diagram described in [Fig.2]
Chaque bloc s'appuie sur un ensemble de techniques déjà connues et d'algorithmes répondant aux besoins spécifiques de la plateforme : la détection de « vidéo événements » et leurs placements correspondant à des types de contenus. Each block is based on a set of already known techniques and algorithms meeting the specific needs of the platform: the detection of “video events” and their placements corresponding to types of content.
Le séquençage individualisé offre à l'utilisateur la possibilité de sélectionner tout ou partie des chapitres d'une vidéo à visualiser avec un repère de temps permettant de se situer lors de la visualisation.
Pour la détection automatique des timecodes permettant le séquençage en chapitres et le placement de vidéo événements, un ensemble d'algorithmes permet de réduire au maximum la fenêtre de recherche de ces derniers. Cet ensemble d'algorithmes est ensuite adapté en fonction du programme et des éléments recherchés. Individualized sequencing offers the user the possibility of selecting all or part of the chapters of a video to be viewed with a time mark allowing them to position themselves during viewing. For the automatic detection of timecodes allowing sequencing in chapters and the placement of video events, a set of algorithms makes it possible to reduce the search window for these as much as possible. This set of algorithms is then adapted according to the program and the elements sought.
La [Fig. B] illustre un exemple d'étapes dans le cas où la vidéo comporte des indices audios ou visuels permettant d'identifier la coupure entre deux chapitres : 1) Premier découpage suite à la détection des indices audio en utilisant la méthode dite de cross-corrélation. La comparaison de deux signaux peut retrouver des similarités entre ces deux derniers. Chaque similarité retrouvée est alors accompagnée d'un score de probabilité. Plus ce score est proche de 1, plus la similarité est forte ; 2) Ajustement grâce à la détection d'indices visuels dans les segments du découpage précédent ; The [Fig. B] illustrates an example of steps in the case where the video includes audio or visual cues making it possible to identify the cut between two chapters: 1) First splitting following the detection of the audio cues using the so-called cross-correlation method . The comparison of two signals can find similarities between the latter two. Each similarity found is then accompanied by a probability score. The closer this score is to 1, the stronger the similarity; 2) Adjustment thanks to the detection of visual cues in the segments of the previous cut;
3) Affinage à partir de la détection de scènes dans le montage vidéo. 3) Refinement based on the detection of scenes in the video edit.
La présente invention permet de décrire sous forme de règles, en fonction du programme, l'enchaînement des algorithmes à utiliser dans le but de détecter les timecodes pertinents. The present invention makes it possible to describe in the form of rules, as a function of the program, the sequence of the algorithms to be used in order to detect the relevant timecodes.
La liste des algorithmes mise à disposition est la suivante : The list of algorithms available is as follows:
- Détection de similitudes audio par « cross-corrélation » ; - Détection et reconnaissance d'un signal audio à partir du modèle de réseaux de neurones convolutifs Youtube-8M ; - Detection of audio similarities by "cross-correlation"; - Detection and recognition of an audio signal from the Youtube-8M convolutional neural network model;
