The method comprises providing a screen of the electronic program guide with at least two windows, wherein the first of the windows shows a guide in the form of a time grid and the channel comprising a plurality of cells in which program listings are displayed of TV; and provide a cursor to select between the first and the second window and to navigate within each of them. The second window shows video on demand (VoD). When selecting one or the other window, the cursor highlights the marked window and provides the necessary means to activate the multimedia content shown in said marked window. That is, in this patent application a traditional electronic program guide (EPG) is combined with a list of VoD content, but keeping each one in different windows. The EPG can also show catch-up content, but there are no relationships between the contents that are displayed to the user.
Por la patente US-B2-8732763 se proporciona un sistema y un método para un interfaz de usuario para mostrar contenido multimedia VoD organizado por horarios de emisión. De hecho en esta patente se proporciona una EPG donde se mezcla contenido multimedia en vivo (//Ve) y VoD. El contenido multimedia VoD mostrado en la EPG no está relacionado con datos de uso del propio usuario. Asimismo, en esta patente, para mostrar el contenido multimedia VoD no se utilizan características del contenido multimedia aparte de su hora de emisión. La interfaz de usuario es exclusiva para dispositivos móviles. US-B2-8732763 provides a system and method for a user interface for displaying VoD multimedia content organized by broadcast schedules. In fact, this patent provides an EPG that mixes live multimedia content (// Ve) and VoD. The VoD multimedia content shown in the EPG is not related to user usage data. Also, in this patent, to show the content Multimedia VoD does not use multimedia content features other than its broadcast time. The user interface is exclusive for mobile devices.
Por la patente US-B2-7793319 se da a conocer sistema y métodos para navegar a través de múltiples canales de contenido multimedia para localizar programas que están ejecutando programas de interés. Esta patente mejora el zapping a través de los canales usando solamente programas de interés y detectando los intervalos publicitarios. No incluye distintas fuentes de contenido multimedia a los canales en vivo. US-B2-7793319 discloses system and methods for navigating through multiple multimedia content channels to locate programs that are running programs of interest. This patent improves zapping through channels using only programs of interest and detecting advertising intervals. It does not include different sources of multimedia content to live channels.
Por otro lado, en los productos actualmente en el mercado, la mayoría de los dispositivos tienen diferentes menús o aplicaciones para diferentes fuentes de contenidos (es decir, el usuario tiene una aplicación específica para YouTube®, otra para Netflix®, otra para Fox®, etc.). Eso implica los siguientes problemas de usabilidad: On the other hand, in the products currently on the market, most devices have different menus or applications for different content sources (that is, the user has a specific application for YouTube®, another for Netflix®, another for Fox® , etc.). That implies the following usability problems:
- Esfuerzo en el acceso a contenidos: En los productos anteriores, los usuarios generalmente, no acceden a los menús de la Smart TV o del decodificador o receptor de televisión (en inglés Set-Top Box (STB)) debido al esfuerzo que les supone a los usuarios de TV. Asimismo, debido al comportamiento de relax y bajo esfuerzo de los usuarios de TV, estos no son conscientes de la oferta de contenidos multimedia que les ofrecen sus SmartTVs o STBs y debido a esto, tienen la sensación de que no hay nada para ellos en la televisión o en el servicio de vídeo que estén utilizando. Por estas razones, llegar a los contenidos multimedia a través de menús explícitos de navegación, no es eficiente para los usuarios ya que, en el mejor de los casos, se deben hacer un mínimo de 4 o 5 pulsaciones para empezar a reproducir un contenido multimedia. El mismo problema se reproduce en las SmartTV, donde cada servicio de TV conlleva utilizar una aplicación distinta, con una interfaz distinta. Sí, el usuario tiene acceso a YouTube®, Netflix® y otros servicios, pero cada fuente de contenido se maneja de manera diferente.  - Effort in accessing content: In the previous products, users generally do not access the menus of the Smart TV or the set-top box (STB) due to the effort involved to TV users. Also, due to the relax behavior and low effort of TV users, they are not aware of the offer of multimedia content offered by their SmartTVs or STBs and because of this, they have the feeling that there is nothing for them in the television or video service they are using. For these reasons, reaching multimedia content through explicit navigation menus is not efficient for users since, at best, a minimum of 4 or 5 keystrokes must be made to start playing multimedia content. . The same problem is reproduced on SmartTVs, where each TV service involves using a different application, with a different interface. Yes, the user has access to YouTube®, Netflix® and other services, but each content source is handled differently.
- Falta de integración de las diferentes fuentes de contenido: Actualmente, tanto las SmartTVs como los STBs habituales permiten encontrar un cierto contenido de vídeo utilizando algún tipo de buscador. El problema es que esa búsqueda suele ser específica de la aplicación que se está usando para consumir el contenido multimedia. Solo AppleTV® en su versión actual permite hacer una búsqueda en varios de los servicios de video que soporta (¡Tunes, Netflix, Hulu, etc.) y solo utilizando la función de búsqueda., lo cual sigue exigiendo un esfuerzo explícito por parte del usuario para la localización activa de un contenido multimedia. - Falta de integración con el comportamiento habitual del usuario: Una vez delante del televisor, los usuarios utilizan habitualmente el zapping para descubrir contenidos multimedia mediante los botones de subir y bajar de canal. No obstante, este comportamiento solo permite recorrer canales de televisión en el orden en que estén configurados en el televisor. Este mecanismo provoca que al final la mayoría de los usuarios restrinjan sus búsquedas a los 10 canales que suelen ver, porque también asocian un cierto tipo de contenido multimedia a cada canal. Eso hace que muchas veces se pierdan contenidos que podrían ser interesantes para ellos porque los emiten en canales que no suelen ver. - Lack of integration of the different content sources: Currently, both the SmartTVs and the usual STBs allow to find a certain video content using some type of search engine. The problem is that this search is usually specific to the application that is being used to consume multimedia content. Only AppleTV® in its current version allows you to search several of the video services it supports (¡Tunes, Netflix, Hulu, etc.) and only using the search function., Which continues to require an explicit effort on the part of the user for active localization of multimedia content. - Lack of integration with the user's usual behavior: Once in front of the TV, users routinely use zapping to discover multimedia content using the channel up and down buttons. However, this behavior only allows TV channels to be traversed in the order in which they are set on the television. This mechanism means that in the end most users restrict their searches to the 10 channels they usually watch, because they also associate a certain type of multimedia content with each channel. That often makes you lose content that could be interesting for them because they broadcast them on channels they don't usually watch.
- Los sistemas de recomendación automática necesitan un perfil claro del usuario:  - Automatic recommendation systems need a clear user profile:
Actualmente algunas empresas ofrecen sistemas automáticos de recomendación basados en el perfil del usuario. Para que estos sistemas funcionen bien, requieren que el usuario lleve un cierto tiempo utilizando el servicio para poder usar estos datos para las recomendaciones. Estos sistemas también requieren que el usuario esté identificado de cara al servicio, utilizando su cuenta de usuario. Esta identificación es sencilla en una aplicación móvil, un sitio web o una aplicación para SmartTV, pero no es usable en una televisión compartida, ya que implicaría que cada usuario de dicha televisión introdujese su identificación cada vez que la va a usar. Asimismo, podría darse el caso de que a los pequeños de la familia se les recomienden contenidos violentos porque no han introducido su identificador. Some companies currently offer automatic recommendation systems based on the user's profile. For these systems to work well, they require the user to use the service for some time to use this data for recommendations. These systems also require that the user be identified for the service, using their user account. This identification is simple in a mobile application, a website or an application for SmartTV, but it is not usable in a shared television, since it would imply that each user of said television entered their identification each time they will use it. Likewise, it could be the case that the children of the family are recommended violent content because they have not introduced their identifier.
Adicionalmente estos sistemas no están integrados de forma transparente con los patrones de navegación estándar de los usuarios (zapping), por lo que aunque son más relajados que un patrón de búsqueda activa siguen exigiendo esfuerzo cognitivo adicional. Exposición de la invención Additionally, these systems are not transparently integrated with users' standard navigation patterns (zapping), so although they are more relaxed than an active search pattern, they still require additional cognitive effort.

Los citados datos de consumo de contenido multimedia los va enviando el dispositivo al servidor, donde son procesados y agregados y posteriormente enviados a la unidad de ordenación donde quedan almacenados. Estos datos de consumo de contenido multimedia preferiblemente incluyen información relativa a uno o más contenidos multimedia consumidos por el dispositivo y a la fecha y hora de consumo del contenido multimedia. En un ejemplo de realización preferido, la unidad de cálculo de similitud asigna diferentes pesos a cada uno de los metadatos utilizados para establecer la similitud entre los diferentes contenidos multimedia, en donde dichos pesos dependen del tipo de contenido multimedia y son configurable en el servidor. Si bien, alternativamente, la unidad de cálculo de similitud también podría asignar iguales pesos a cada uno de los metadatos utilizados. The aforementioned multimedia content consumption data is sent by the device to the server, where they are processed and added and subsequently sent to the management unit where they are stored. This multimedia content consumption data preferably includes information regarding one or more multimedia contents consumed by the device and the date and time of consumption of the multimedia content. In a preferred embodiment, the similarity calculation unit assigns different weights to each of the metadata used to establish the similarity between the different multimedia contents, wherein said weights depend on the type of multimedia content and are configurable on the server. Although, alternatively, the similarity calculation unit could also assign equal weights to each of the metadata used.
Según la presente invención, la obtención del contenido multimedia por el servidor (etapa a) puede realizarse periódicamente cada cierto periodo de tiempo (por ejemplo, durante las horas valle de consumo del servicio), o en tiempo real, cada vez que se produce un cambio en el catálogo de contenidos multimedia. According to the present invention, the obtaining of the multimedia content by the server (step a) can be carried out periodically every certain period of time (for example, during the service consumption hours of the service), or in real time, each time a Change in the multimedia content catalog.

Por tanto, la presente invención proporciona una nueva tecnología de descubrimiento de contenidos multimedia para dispositivos capaces de mostrar vídeos (Set Top Boxes, televisores conectados a Internet, Smartphones, Tablets, navegadores web, videoconsolas, etc.), agnóstico a la fuente del contenido multimedia. Therefore, the present invention provides a new multimedia content discovery technology for devices capable of displaying videos (Set Top Boxes, televisions connected to the Internet, Smartphones, Tablets, web browsers, video consoles, etc.), agnostic to the content source multimedia.
La invención basa sus principios en el mecanismo de zapping, que es el que más utilizan los usuarios para navegar por los canales de sus televisores, y de la información que muestra la EPG de programación. Este componente aparece siempre cuando el usuario hace un cambio de canal o pulsa un botón determinado de su mando a distancia (generalmente "Info" u ΌΚ"). La EPG se encarga de mostrar al usuario información sobre el contenido multimedia en emisión o contenidos multimedia futuros dentro de un canal seleccionado. El componente EPG recibe toda la información de los contenidos multimedia que se emitirán en un canal a través del satélite, la antena de TV o, en servicios OTT, mediante el acceso a APIs de internet que proveen de esta información y permiten a los usuarios el poder evaluar los contenidos multimedia presentes y futuros de los canales de TV. Mediante estas características, se consigue que los usuarios encuentren contenidos multimedia atractivos más rápidamente, con menor número de pulsaciones en los botones del mando a distancia o de interacciones con otros interfaces de manejo. The invention bases its principles on the zapping mechanism, which is the one that users use the most to navigate the channels of their televisions, and the information shown by the programming EPG. This component always appears when the user makes a channel change or presses a specific button on his remote control (usually "Info" or ΌΚ "). The EPG is responsible for showing the user information about the broadcast multimedia content or multimedia content futures within a selected channel. EPG component receives all the information of the multimedia contents that will be broadcast on a channel through the satellite, the TV antenna or, in OTT services, through access to Internet APIs that provide this information and allow users the power Evaluate the present and future multimedia contents of TV channels. Through these features, users can find attractive multimedia content more quickly, with fewer keystrokes on the remote control buttons or interactions with other operating interfaces.
Por otro lado, el uso de recomendaciones pre-calculadas basadas únicamente en similitud entre contenidos multimedia permite presentar al usuario una lista de contenidos multimedia relacionados distinta para cada contenido multimedia de manera rápida y reduce los problemas de los sistemas de recomendación basados en datos de consumo de usuario, como por ejemplo el arranque en frío (cold start) para usuarios nuevos o poco activos. On the other hand, the use of pre-calculated recommendations based solely on similarity between multimedia content allows the user to present a list of different related multimedia contents for each multimedia content quickly and reduces the problems of recommendation systems based on consumption data of user, such as cold start for new or less active users.
Además, la posibilidad de mezclar contenido multimedia de diferentes fuentes de contenido, aumenta exponencialmente la variedad del catálogo disponible para el usuario, resultando mucho más flexible que otros servicios de vídeo con interfaces distintos para cada fuente de contenido. In addition, the possibility of mixing multimedia content from different content sources exponentially increases the variety of the catalog available to the user, being much more flexible than other video services with different interfaces for each content source.
Por último, estas dos ventajas de la mezcla de fuentes de contenido y la disponibilidad de la similitud entre contenidos multimedia basado en los metadatos del usuario, se unen para ofrecer una ventaja más: la posibilidad de crear canales virtuales mezclando contenidos multimedia en vivo (live), por ejemplo programas de televisión o partidos de fútbol/baloncesto/tenis, etc., y VoD, sin necesidad de planificar una parrilla desde cero. Finally, these two advantages of mixing content sources and the availability of similarity between multimedia content based on user metadata, come together to offer one more advantage: the possibility of creating virtual channels by mixing live multimedia content (live) ), for example television programs or football / basketball / tennis matches, etc., and VoD, without planning a grid from scratch.
La presente invención es además altamente extensible, con mejoras como el uso de patrones de navegación para complementar la similitud de contenidos multimedia o crear micro-perfiles para personalización de grado más fino. Breve descripción de los dibujos The present invention is also highly extensible, with improvements such as the use of navigation patterns to complement the similarity of multimedia content or create micro-profiles for finer grade customization.

Descripción detallada de un ejemplo de realización Detailed description of an embodiment example
La Fig. 1 muestra un ejemplo de realización preferido del sistema propuesto para identificar contenido multimedia para dispositivos capaces de mostrar contenido multimedia. Según este ejemplo de realización preferido, el sistema propuesto incluye un dispositivo 1 capaz de mostrar contenido multimedia, un servidor 3, un catálogo de contenidos multimedia 2, una unidad de cálculo de similitud 4 y una unidad de ordenación 5. Fig. 1 shows a preferred embodiment of the proposed system for identifying multimedia content for devices capable of displaying multimedia content. According to this preferred embodiment, the proposed system includes a device 1 capable of displaying multimedia content, a server 3, a catalog of multimedia contents 2, a similarity calculation unit 4 and an ordering unit 5.
El citado servidor 3 está configurado y adaptado para establecer una conexión con el dispositivo 1 , con un catálogo de contenidos multimedia 2 y con una unidad de cálculo de similitud 4 a través de al menos una red de comunicaciones, por ejemplo Internet. Said server 3 is configured and adapted to establish a connection with the device 1, with a catalog of multimedia contents 2 and with a similarity calculation unit 4 through at least one communications network, for example the Internet.
El catálogo de contenidos multimedia 2 incluye al menos una memoria para almacenar contenidos multimedia junto con unos metadatos identificativos de cada contenido multimedia almacenado. El contenido multimedia almacenado en el catálogo de contenidos multimedia 2 puede proceder de diferentes o de iguales fuentes de contenido incluyendo canales de televisión, catálogos de vídeos bajo demanda, sitios de internet, vídeos personales de un usuario disponibles en dispositivos accesibles desde el servidor 3 y/o redes sociales. En cuanto a los metadatos identificativos, para un funcionamiento óptimo, el catálogo de contenidos multimedia incluye al menos: título, tipo de contenido (película, serie, documental, etc.), director, actores, descripción, imagen representativa, hora de inicio y hora final (para programas de TV). No obstante la presente invención puede funcionar (con un comportamiento algo menos eficiente) con conjuntos más reducidos de metadatos. Adicionalmente, el propietario del servicio, es decir, el propietario de un servicio de televisión que ofrece una serie de canales de televisión (por ejemplo Telefónica), también puede incluir otros datos como precios, suscripción que requiere el contenido multimedia y/o otras variables necesarias para el correcto funcionamiento del servicio. The multimedia content catalog 2 includes at least one memory for storing multimedia content together with identifying metadata of each stored multimedia content. The multimedia content stored in the multimedia content catalog 2 may come from different or equal sources of content including television channels, catalogs of videos on demand, internet sites, a user's personal videos available on devices accessible from server 3 and / or social networks. As for the identification metadata, for optimal operation, the multimedia content catalog includes at least: title, type of content (film, series, documentary, etc.), director, actors, description, representative image, start time and end time (for TV shows). However, the present invention can work (with somewhat less efficient behavior) with smaller sets of metadata. Additionally, the owner of the service, that is, the owner of a television service that offers a series of television channels (for example, Telefónica), can also include other data such as prices, subscription that requires multimedia content and / or other variables necessary for the proper functioning of the service.
La unidad de cálculo de similitud 4 incluye uno o más procesadores y al menos una memoria y está adaptada y configurada para establecer una similitud entre diferentes contenidos multimedia obtenidos por el servidor 3 en base a los metadatos identificativos de cada contendido multimedia. Esta unidad de cálculo de similitud 4 puede ser remota al servidor 3 y ser operativamente conectable a éste último, o puede ser una unidad del propio servidor 3. The similarity calculation unit 4 includes one or more processors and at least one memory and is adapted and configured to establish a similarity between different multimedia contents obtained by the server 3 based on the identifying metadata of each multimedia content. This similarity calculation unit 4 may be remote to server 3 and be operably connectable to the latter, or it may be a unit of the server itself 3.
Finalmente, la unidad de ordenación incluye uno o más procesadores y está configurada y adaptada para utilizar la similitud establecida por la unidad de cálculo de similitud 4 y unos datos de consumo del dispositivo 1 para generar una lista de contenido multimedia particularizada al dispositivo 1 , a la franja horaria, y al día de la semana en que se está usando el dispositivo 1. Al igual que la unidad de cálculo de similitud 4, esta unidad de ordenación puede ser remota al servidor 3 y ser operativamente conectable a éste último, o puede ser una unidad del propio servidor 3. Asimismo, debe notarse que la utilización de la unidad de ordenación 5 es opcional en el sistema propuesto, es decir, otros ejemplos de realización de la invención pueden no incorporar a esta unidad. Finally, the sorting unit includes one or more processors and is configured and adapted to use the similarity established by the similarity calculation unit 4 and consumption data of the device 1 to generate a list of multimedia content particularized to the device 1, a the time slot, and the day of the week in which device 1 is being used. Like the similarity calculation unit 4, this sorting unit may be remote to server 3 and be operably connectable to the latter, or it may be a unit of the server itself 3. Also, it should be noted that the use of the sorting unit 5 is optional in the proposed system, that is, other embodiments of the invention may not incorporate into this unit.
Con referencia ahora a la Fig. 2, en la misma se muestra un ejemplo de realización preferido del método propuesto para identificar contenido multimedia para dispositivos capaces de mostrar contenido multimedia. El servidor 3 accede al catálogo de contenidos multimedia 2, bien periódicamente o solamente cuando se produce un cambio en el catálogo de contenidos multimedia 2, para obtener la información de los contenidos multimedia disponibles (tal como se indicado anteriormente estos pueden proceder de diversas fuentes de contenido) incluidos sus metadatos. El servidor 3 preferiblemente almacena en una base de datos local (o en una memoria) todo el listado de contenido multimedia, de tal forma que cada contenido multimedia irá caracterizado por un identificador, el enlace al contenido multimedia y los metadatos que lo caracterizan (título, director, tipo de contenido, actores, género, sub-género, una imagen representativa, etc.). Referring now to Fig. 2, there is shown a preferred embodiment of the proposed method for identifying multimedia content for devices capable of displaying multimedia content. The server 3 accesses the multimedia content catalog 2, either periodically or only when there is a change in the multimedia content catalog 2, to obtain the information of the available multimedia contents (as indicated above these can come from various sources of content) including your metadata. The server 3 preferably stores the entire multimedia content list in a local database (or in a memory), so that each multimedia content will be characterized by an identifier, the link to the multimedia content and the metadata that characterize it (title , director, type of content, actors, gender, sub-genre, a representative image, etc.).
Seguidamente, cada contenido multimedia adquirido y sus metadatos se envían a la unidad de cálculo de similitud 4 para que aplique una serie de criterios de comparación entre los contenidos multimedia que va recibiendo en base a los metadatos. Los criterios de comparación aplicados pueden depender del tipo de contenido multimedia detectado. En un ejemplo de realización, los citados criterios de comparación comprenden: para películas (título, género, director y actores); para contenido multimedia infantil (título, género y opcionalmente director), adicionalmente, para contenido multimedia infantil se podría limitar a la recepción de contenidos multimedia solo del mismo tipo; para programas de televisión y/o para series (título, tipo, género y descripción), opcionalmente también se podría incluir la fecha de inicio y fin. De cualquier modo, que cada tipología de contenido multimedia tenga unos metadatos asociados en base a los que se establecen las similitudes, no es excluyente para que dicho metadato no se aplique en otros tipos de contenidos multimedia, al tratarse el ejemplo de realización anterior simplemente de una posible realización, no exhaustiva ni limitativa. Adicionalmente, se pueden asignar una serie de pesos a cada uno de los metadatos utilizados para optimizar la similitud, de forma que aumente o disminuya la importancia de los campos a la hora de calcular esa similitud. Estos pesos pueden variar por tipo de contenido multimedia, y son calculables de forma empírica a través de un análisis de uso de contenidos multimedia o estableciendo un conjunto canónico de similitudes mediante una labor documental. Un ejemplo representativo se muestra en las siguientes tablas. Subsequently, each multimedia content acquired and its metadata are sent to the similarity calculation unit 4 so that it applies a series of comparison criteria between the multimedia contents that it receives based on the metadata. The comparison criteria applied may depend on the type of multimedia content detected. In an exemplary embodiment, the aforementioned comparison criteria include: for films (title, genre, director and actors); for children's multimedia content (title, genre and optionally director), additionally, for children's multimedia content it could be limited to receiving multimedia content only of the same type; for television programs and / or series (title, type, genre and description), optionally the start and end date could also be included. In any case, that each type of multimedia content has some associated metadata based on those that establish the similarities, it is not exclusive so that said metadata is not applied in other types of multimedia content, as the previous embodiment example is simply a possible realization, not exhaustive or limiting. Additionally, a series of weights can be assigned to each of the metadata used to optimize the similarity, so as to increase or decrease the importance of the fields when calculating that similarity. These weights may vary by type of multimedia content, and are empirically calculable through an analysis of the use of multimedia content or by establishing a canonical set of similarities through documentary work. A representative example is shown in the following tables.

Tras procesar los metadatos de cada contenido multimedia, la unidad de cálculo de similitud 4 almacena en su base de datos (o memoria) qué contenidos multimedia son similares a uno dado. Dichas similitudes se calculan independientemente del tipo de contenido multimedia, usando los metadatos asociados a cada contenido multimedia de manera transversal. En cualquier caso, es importante reseñar que: After processing the metadata of each multimedia content, the similarity calculation unit 4 stores in its database (or memory) what multimedia contents are similar to a given one. These similarities are calculated independently of the type of multimedia content, using the metadata associated with each multimedia content in a transversal way. In any case, it is important to note that:
- A partir de una película es posible obtener contenidos multimedia que son similares pero pertenecen a otros tipos. Una película de Star Wars puede ser similar a un documental de Star Wars o a una serie de Star Wars.  - From a movie it is possible to obtain multimedia contents that are similar but belong to other types. A Star Wars movie can be similar to a Star Wars documentary or a Star Wars series.
Las similitudes quedan pre-calculadas para que luego sea más rápido mostrarlas en el dispositivo 1. Cada vez que se recibe un contenido multimedia nuevo del servidor 3 (que no estuviese procesado previamente), se reprocesan las similitudes (refresco de las similitudes), ya que puede ser más similar a uno dado que los que ya existían en la base de datos de la unidad de cálculo de similitud 4. Este proceso sucede en el mismo momento en que el servidor 3 recorre el catálogo de contenidos multimedia 2: si el contenido ya existía previamente, no se hace nada, pero si es nuevo, se hace el nuevo cálculo de similitud. The similarities are pre-calculated so that it is faster to display them on device 1. Each time a new multimedia content is received from server 3 (which was not previously processed), the similarities are reprocessed (refresh of the similarities), since it may be more similar to one given that those that already existed in the database of the similarity calculation unit 4. This process happens at the same time that the server 3 goes through the multimedia content catalog 2: if the content already existed previously, nothing is done, but if it is new, the new one is made similarity calculation.
Existen diversos algoritmos capaces de calcular la similitud entre contenidos multimedia en base a metadatos identificativos. Un ejemplo representativo y preferido de la presente invención es la familia de algoritmos de recuperación de información basados en el concepto de Vector Space Model (VSM) con ponderación mediante la técnica de TF-IDF (Term Frequency - Inverse Document Frequency). Sin embargo la presente invención es capaz de funcionar con cualquier algoritmo que sea capaz de producir una métrica de similitud entre pares arbitrarios de contenidos, por ejemplo algoritmos de Collaborative Filtering, modelos generativos (LDA), modelos basados en redes neuronales (tipo word2vec), modelos basados en medidas de la similitud semántica, etc. There are several algorithms capable of calculating the similarity between multimedia content based on identifying metadata. A representative and preferred example of the present invention is the family of information retrieval algorithms based on the concept of Vector Space Model (VSM) with weighting using the TF-IDF (Term Frequency - Inverse Document Frequency) technique. However, the present invention is capable of working with any algorithm that is capable of producing a metric of similarity between arbitrary pairs of contents, for example Collaborative Filtering algorithms, generative models (LDA), models based on neural networks (type word2vec), models based on semantic similarity measures, etc.
Adicionalmente, según este ejemplo de realización preferido, la unidad de ordenación 5 almacena los datos de similitud previamente calculados y utiliza los datos de consumo del dispositivo 1 para proporcionar una métrica de similitud complementaria y particularizada basada en técnicas de Filtrado Colaborativo, que deduzca similitud entre contenidos multimedia en función de patrones de uso. Esta métrica no necesita metadatos pero sí datos de usuarios, por lo que puede ser un buen complemento a la métrica principal. Additionally, according to this preferred embodiment, the sorting unit 5 stores the previously calculated similarity data and uses the consumption data of the device 1 to provide a complementary and particularized similarity metric based on Collaborative Filtering techniques, which deduces similarity between multimedia content based on usage patterns. This metric does not need metadata but user data does, so it can be a good complement to the main metric.
Según la presente invención, en el lado del dispositivo 1 , el funcionamiento del método propuesto es similar al de una televisión convencional. Una vez encendido el dispositivo 1 , el usuario se encontrará con un determinado canal de televisión emitiendo un determinado contenido multimedia 301 (ver Figs. 3a y 3b). Este canal de televisión puede ser un canal emitido convencional (como los que se reciben en un televisor vía satélite) o, alternativamente, puede ser un canal dinámico formado por una secuencia de vídeos tomados de un catálogo de VoD, encadenados uno tras otro. En cuanto a la información relativa al contenido multimedia similar a uno dado, ésta puede ser una lista de contenidos multimedia recomendados por el propietario del servicio, o simplemente una lista de contenidos multimedia del mismo tipo o género. Asimismo, si existen suficientes datos de consumo del dispositivo 1 , la lista de contenidos multimedia puede comprender contenido multimedia similar a cosas que el usuario haya visto recientemente (utilizando los datos de consumo de contenidos que se irán almacenando en la unidad de ordenación 5), utilizando los mismos criterios de similitud mencionados anteriormente. Este canal dinámico se referirá a continuación como "canal virtual". En cualquier caso, el usuario estará visualizando un contenido en el dispositivo 1. En caso de que solicite un cambio de canal (utilice los botones de su mando a distancia o los iconos de su pantalla táctil), lo que pasará es que efectivamente cambiará de canal: puede ser al siguiente canal real si el servicio dispone de este tipo de contenidos o puede ser al siguiente canal virtual. Los canales virtuales los creará el propietario del servicio ofrecido: pueden ser por tipo de programa (canales de películas, series, documentales e infantil), temáticos (películas de los 80), etc. El propietario del servicio dispondrá de una herramienta donde asignar metadatos a canales virtuales de tal manera que la lista de contenidos utilice estos metadatos para encontrar contenidos similares mediante la unidad de cálculo de similitud 4. Por ejemplo, el propietario del servicio quiere crear un canal virtual de Ciencia Ficción sin necesidad de planear una parrilla de programación desde cero. Mediante esta herramienta de creación de canales virtuales, simplemente elegiría como etiqueta para construir las similitudes "Género: Ciencia Ficción"; la invención obtendría todos los contenidos multimedia disponibles (sean series, películas o documentales) que incluyeran este dato para construir la lista de contenidos multimedia que compondrían este canal virtual. According to the present invention, on the side of the device 1, the operation of the proposed method is similar to that of a conventional television. Once the device 1 is switched on, the user will find a certain television channel broadcasting a certain multimedia content 301 (see Figs. 3a and 3b). This television channel may be a conventional broadcast channel (such as those received on a satellite television) or, alternatively, it may be a dynamic channel formed by a sequence of videos taken from a VoD catalog, chained one after the other. As for the information related to multimedia content similar to a given one, this may be a list of multimedia contents recommended by the service owner, or simply a list of multimedia content of the same type or genre. Also, if there is sufficient consumption data of the device 1, the multimedia content list may comprise content multimedia similar to things that the user has recently seen (using the content consumption data that will be stored in the sorting unit 5), using the same similarity criteria mentioned above. This dynamic channel will be referred to below as "virtual channel". In any case, the user will be viewing a content on the device 1. In case you request a channel change (use the buttons on your remote control or the icons on your touch screen), what will happen is that it will effectively change channel: it can be to the next real channel if the service has this type of content or it can be to the next virtual channel. The virtual channels will be created by the owner of the service offered: they can be by type of program (movie, series, documentary and children's channels), thematic (80's movies), etc. The service owner will have a tool to assign metadata to virtual channels in such a way that the content list uses these metadata to find similar content by means of the similarity calculation unit 4. For example, the service owner wants to create a virtual channel Science Fiction without planning a programming grid from scratch. Using this virtual channel creation tool, I would simply choose as a label to build the similarities "Gender: Science Fiction"; The invention would obtain all the multimedia content available (be it series, movies or documentaries) that included this data to build the list of multimedia contents that would comprise this virtual channel.
La presente invención permite mezclar canales reales y virtuales de tal forma que estén totalmente integrados en la experiencia de uso y se pueda usar el zapping aunque sean contenidos bajo demanda procedentes de internet. The present invention allows real and virtual channels to be mixed in such a way that they are fully integrated into the user experience and zapping can be used even if they are on demand from the Internet.
Como en cualquier servicio de televisión convencional, la parte inferior de la pantalla del dispositivo 1 estará ocupada por una guía electrónica de programas (EPG) o miniguía, es decir una interfaz gráfica del dispositivo 1 que muestra información sobre el programa actual y sobre los contenidos multimedia futuros de dicho canal ordenados de forma consecutiva por fecha u hora de emisión. Para el caso de los canales virtuales, la ordenación de contenidos multimedia podrá venir dada por el propietario del servicio ajustándose a sus requisitos y necesidades particulares o por el grado de similitud de los contenidos multimedia con el criterio especificado (es decir, los contenidos multimedia más similares se situarían más cerca del contenido multimedia reproduciéndose en ese momento 301). No obstante, la presente invención añade otro elemento al EPG (o miniguía avanzada tal como se referirá seguidamente) que ayuda a descubrir contenido multimedia más rápidamente y que en un ejemplo de realización particular se representa en la Fig. 3a, no limitativo puesto que la distribución de los diferentes datos en la miniguía avanzada podría mostrarse en diferentes posiciones y de diferentes modos. As in any conventional television service, the lower part of the screen of the device 1 will be occupied by an electronic program guide (EPG) or mini-guide, that is to say a graphical interface of the device 1 that shows information about the current program and the contents Future multimedia of said channel ordered consecutively by date or time of broadcast. In the case of virtual channels, the management of multimedia content may be given by the owner of the service according to their particular requirements and needs or by the degree of similarity of multimedia content with the specified criteria (that is, multimedia content more similar would be closer to multimedia content playing at that time 301). Do not However, the present invention adds another element to the EPG (or advanced mini-guide as will be referred to below) which helps to discover multimedia content more quickly and which in a particular embodiment is represented in Fig. 3a, not limiting since the distribution of the different data in the advanced mini-guide could be displayed in different positions and in different ways.
Según este ejemplo de realización particular, los datos mostrados en la miniguía avanzada son: According to this particular embodiment, the data shown in the advanced mini-guide are:
- En una columna situada a la izquierda del dispositivo 1 limitando con un borde lateral de un pantalla del dispositivo 1 , un listado de contenidos multimedia 305 (es decir de los programas) que se están mostrando en un determinado momento en canales de televisión diferentes al canal de televisión que está mostrando el contenido multimedia 301 (por ejemplo una película). La novedad es que este listado se mantiene en pantalla cuando el usuario va haciendo zapping y eso le permite ver con antelación qué contenido multimedia se está emitiendo en cada canal. - In a column to the left of the device 1 limiting with a side edge of a screen of the device 1, a list of multimedia contents 305 (ie of the programs) that are being displayed at a certain time on television channels other than TV channel that is displaying 301 multimedia content (for example a movie). The novelty is that this list is kept on screen when the user is zapping and that allows you to see in advance what multimedia content is being broadcast on each channel.
- En un fila situada por debajo de la citada columna y que limita con un borde inferior de la pantalla del dispositivo 1 , se proporciona información 302 del canal de televisión que está emitiendo el contenido multimedia 301 (la citada película), por ejemplo de la imagen y logotipo del canal (procedente del catálogo de contenidos multimedia 2). - In a row below the said column and which borders a lower edge of the screen of the device 1, information 302 of the television channel that is broadcasting the multimedia content 301 (said film) is provided, for example of the image and logo of the channel (from the multimedia content catalog 2).
- En una parte central 303 de dicha fila, se muestra información del contenido multimedia 301 (muestra información de la película). En esta parte central 303 la miniguía avanzada puede mostrar una imagen del contenido multimedia 301 , el título del contenido multimedia 301 , el género, la barra de progreso y los botones del mando que pueden desencadenar alguna acción sobre el contenido multimedia 301 (como grabarlo o guardarlo en favoritos). En caso de que el dispositivo 1 disponga de un interfaz táctil, en vez de los botones del mando, se mostrarían iconos que pueden accionarse.  - In a central part 303 of said row, multimedia content information 301 is shown (shows movie information). In this central part 303 the advanced mini-guide can show an image of the multimedia content 301, the title of the multimedia content 301, the genre, the progress bar and the buttons of the remote control that can trigger some action on the multimedia content 301 (such as recording it or save it to favorites). If the device 1 has a touch interface, instead of the buttons on the remote, icons that can be operated will be displayed.
- En una parte derecha 304 de dicha fila, se muestra información del contenido multimedia siguiente (por ejemplo un programa de entretenimiento) que se emitirá en ese canal de televisión. Esta parte derecha 304 también podrá mostrar la imagen del contenido multimedia que se emitirá a continuación, aunque oscurecida para que se distinga de la imagen del contenido multimedia actual 301.  - In a right part 304 of said row, information of the following multimedia content (for example an entertainment program) that will be broadcast on that television channel is displayed. This right part 304 may also display the image of the multimedia content that will be broadcast next, although obscured to distinguish it from the image of the current multimedia content 301.
En el caso de contenidos multimedia VoD, no habrá barra de progreso, ya que cualquier contenido multimedia podrá verse en cualquier momento (dado que son contenidos multimedia bajo demanda). El logotipo del canal virtual creado a partir de este tipo de contenidos multimedia será aquel proporcionado por el propietario del servicio al crear el canal. In the case of VoD multimedia content, there will be no progress bar, since any multimedia content can be viewed at any time (since they are multimedia content on demand). The virtual channel logo created from this type of Multimedia content will be that provided by the service owner when creating the channel.
En una EPG convencional, el usuario podría desplazarse hacia programas del futuro y ver su información, guardar recordatorios, grabarlos, etc. La presente invención utiliza este comportamiento para integrar el descubrimiento de contenidos multimedia de otras fuentes de contenido en la miniguía avanzada. Por tanto, cuando el usuario se desplaza a través de la miniguía avanzada, por ejemplo hacia la derecha, lo que vería sería algo similar a lo mostrado en la Fig. 3b. Como se ilustra en la figura, se muestra información relativa, por ejemplo en una lista 400, de uno o más contenidos multimedia semánticamente relacionados con el que se está viendo actualmente (contenido multimedia 301), de forma que los usuarios tienen una indicación rápida e intuitiva del grado de interés que pueden tener para ellos. Esta lista 400 ofrece contenidos multimedia procedentes de diversas fuentes de contenido (por ejemplo, una película que están emitiendo en otro canal en ese momento, algo que vayan a emitir esa noche, un contenido multimedia de VoD de pago, contenidos multimedia VoD gratuitos, contenidos multimedia procedentes de Internet, etc.). Preferiblemente, según la invención, los contenidos multimedia similares están ordenados por similitud al contenido de referencia (el que se está visualizando en ese determinado momento 301), de forma que navegar por la lista 400 supone intuitivamente irse alejando en la relación con el mencionado contenido de referencia 301. El flujo para solicitar los contenidos multimedia similares a uno dado se muestra en la Fig. 4. In a conventional EPG, the user could scroll to future programs and view their information, save reminders, record them, etc. The present invention uses this behavior to integrate the discovery of multimedia content from other content sources in the advanced mini-guide. Therefore, when the user moves through the advanced mini-guide, for example to the right, what he would see would be something similar to that shown in Fig. 3b. As illustrated in the figure, relative information is shown, for example in a list 400, of one or more multimedia content semantically related to the one currently being viewed (multimedia content 301), so that users have a quick indication and Intuitive degree of interest they may have for them. This list 400 offers multimedia content from various content sources (for example, a movie that they are broadcasting on another channel at that time, something they will broadcast that night, paid multimedia VoD content, free VoD multimedia content, content multimedia from the Internet, etc.). Preferably, according to the invention, similar multimedia contents are ordered by similarity to the reference content (the one being displayed at that particular moment 301), so that browsing the list 400 intuitively implies moving away in relation to said content. reference 301. The flow to request multimedia contents similar to a given one is shown in Fig. 4.
Como se ve en la Fig. 4, cuando el dispositivo 1 solicita una lista 400 de contenidos multimedia similares al actualmente en pantalla 301 , se envía una petición al servidor 3 para que devuelva la lista 400, que, opcionalmente, puede estar ordenada por el consumo del dispositivo 1 (dependiendo del ejemplo de realización utilizado). Cuando se recibe la lista 400 desde la unidad de ordenación 5, se filtra si es necesario para ver los contenidos multimedia que están disponibles en ese momento, ya que quizá se opte por mostrar solo contenidos multimedia actualmente en emisión, contenidos solo de live, etc. En la Fig. 4 se muestra también el envío de datos de consumo al servidor 3 (para su agregación en caso necesario) y a la unidad de ordenación 5, flujo que no existiría si se prescindiese de este último. As seen in Fig. 4, when the device 1 requests a list 400 of multimedia contents similar to the one currently displayed on screen 301, a request is sent to the server 3 to return the list 400, which, optionally, may be ordered by the consumption of device 1 (depending on the embodiment used). When the list 400 is received from the sorting unit 5, it is filtered if necessary to see the multimedia contents that are currently available, since it may be decided to show only multimedia content currently in broadcast, live only content, etc. . In Fig. 4 it is also shown the sending of consumption data to server 3 (for aggregation if necessary) and to the sorting unit 5, a flow that would not exist if the latter were dispensed with.
En el caso de manejo con el mando a distancia del dispositivo 1 , los botones de subir y bajar de canal seguirán ejecutando esa misma función. Si el usuario utiliza los botones de flechas del mando, podrá desplazarse por los contenidos multimedia similares y seleccionarlos mediante el botón OK o equivalente. Si el usuario tiene permisos para ver el contenido multimedia, lo podrá ver (se cambiará a ese canal, empezará la reproducción del mismo, etc.), mientras que si no puede verlo, le aparecerá una ficha de detalle con la información sobre el contenido multimedia y las acciones que el servicio permita sobre él (alquilarlo, grabarlo, guardarlo en una lista de favoritos, etc.). Si se pulsa OK sobre los contenidos multimedia de canales de televisión que no se estén emitiendo en ese momento (contenidos multimedia pasados o futuros), también aparecerá la ficha con los detalles, como en una EPG convencional. No obstante, dado que la presente invención es agnóstica a la fuente del contenido multimedia, si el servicio está integrado con contenido multimedia de catch-up (contenido previamente emitido en canales de televisión convencionales), pulsando OK se podría reproducir contenido multimedia de este tipo. In the case of operation with the remote control of the device 1, the channel up and down buttons will continue to perform the same function. If the user uses the arrow buttons on the remote, he can scroll through the similar multimedia contents and select them using the OK button or equivalent. If the user has permissions to view the multimedia content, they can watch it (it will be changed to that channel, it will start playing it, etc.), while if it cannot see it, a detail sheet will appear with the information about the content multimedia and the actions that the service allows on it (rent it, record it, save it to a list of favorites, etc.). If you press OK on the multimedia contents of television channels that are not currently being broadcast (past or future multimedia content), the tab with the details will also appear, as in a conventional EPG. However, since the present invention is agnostic to the source of multimedia content, if the service is integrated with multimedia catch-up content (content previously broadcast on conventional television channels), pressing OK could reproduce multimedia content of this type. .
La lista 400 de contenidos multimedia similares puede también aparecer cuando el usuario se desplaza hacia contenidos multimedia futuros, mostrando en este caso aquellos que más se parecen al que se muestre en ese punto de la miniguía avanzada. Una vez que se selecciona uno de los contenidos multimedia de la lista 400 de contenidos multimedia similares, la miniguía avanzada se actualiza con la información correspondiente. Si el contenido multimedia es un VoD, la miniguía avanzada presentará la información como si de un canal virtual se tratase, basándose en contenidos multimedia procedentes de ese canal virtual (si el contenido multimedia pertenecía a uno) o en los que haya disponibles en la fuente de contenido de donde proceda el contenido multimedia. The list 400 of similar multimedia content may also appear when the user moves to future multimedia content, in this case showing those that most closely resemble the one displayed at that point in the advanced mini-guide. Once one of the multimedia contents is selected from the list 400 of similar multimedia contents, the advanced mini-guide is updated with the corresponding information. If the multimedia content is a VoD, the advanced mini-guide will present the information as if it were a virtual channel, based on multimedia content coming from that virtual channel (if the multimedia content belonged to one) or those available at the source of content where the multimedia content comes from.
Tal como ya se ha indicado anteriormente, la lista 400 de contenidos multimedia similares mostradas en el punto anterior, se puede ordenar mediante la unidad de ordenación 5, una vez que esta unidad empiece a recibir información, automáticamente, sobre el consumo del dispositivo 1. La presente invención no requiere que el usuario se identifique con credenciales para recibir esta información personalizada. Los datos de consumo se asocian a un identificador de dispositivo 1 , a una franja horaria y al día de la semana. Este "perfilado indirecto" ayuda a conseguir criterios adicionales de ordenación (en añadido al primario de similitud entre contenidos multimedia) que se perciban como válidos por parte del usuario y minimiza la posibilidad de que se muestren en las primeras posiciones contenidos multimedia inadecuados para ese usuario o para ese día y hora. As already indicated above, the list 400 of similar multimedia contents shown in the previous point can be sorted by means of the sorting unit 5, once this unit automatically starts receiving information about the consumption of the device 1. The present invention does not require the user to identify themselves with credentials to receive this personalized information. The consumption data is associated with a device identifier 1, a time slot and the day of the week. This "indirect profiling" helps to achieve additional sorting criteria (in addition to the primary similarity between multimedia content) that are perceived as valid by the user and minimizes the possibility of displaying inappropriate multimedia content in the first positions for that user. or for that day and time.
Este mecanismo de "perfilado indirecto", unido a que los contenidos multimedia de Infantil, solo muestran como similares otros contenidos multimedia de Infantil, permitiendo evitar situaciones como las que se dan con sistemas de recomendación habituales donde un adulto recibe recomendaciones para niños solo porque sus hijos han estado usando el servicio intensamente durante el fin de semana. Es decir, se trata de un mecanismo equivalente a la creación de micro-perfiles para los usuarios, de forma jerárquica, integrando patrones de uso espacio-temporales (por dispositivo y por franja horaria recurrente). This mechanism of "indirect profiling", together with that the multimedia contents of Infantil, only show similar other multimedia contents of Infantil, allowing to avoid situations such as those that occur with habitual recommendation systems where a adult receives recommendations for children just because their children have been using the service intensively over the weekend. That is to say, it is a mechanism equivalent to the creation of micro-profiles for users, in a hierarchical way, integrating patterns of space-time use (by device and by recurring time slot).
La presente invención, en otro ejemplo de realización, presenta también un mecanismo anti- spoilers para series. Es decir, si el contenido multimedia que se está viendo es una serie, en la lista 400 de contenidos multimedia relacionados se mostrará un elemento "serie" en función de la similitud, como es habitual. Pero el capítulo concreto de esa serie que se muestre, cumplirá los siguientes criterios: The present invention, in another exemplary embodiment, also presents an anti-spoiler mechanism for series. That is, if the multimedia content that is being watched is a series, a "series" element will be displayed in the list 400 of related multimedia content, as usual. But the specific chapter of that series shown, will meet the following criteria:
1. Se recomienda el capítulo 1 de la primera temporada priorizando VoD sobre series en canales. 1. Chapter 1 of the first season is recommended prioritizing VoD over series on channels.
2. Si en los canales tradicionales están emitiendo un cierto capítulo de una serie, en la lista 400 de contenidos multimedia similares a ese capítulo se volverá a mostrar el episodio 1 de la temporada 1 , por si el usuario quiere ver la serie desde el principio. 2. If in the traditional channels they are broadcasting a certain chapter of a series, in the list 400 of multimedia contents similar to that chapter the episode 1 of season 1 will be shown again, in case the user wants to see the series from the beginning .
3. Solo se muestra en la lista 400 un capítulo de cada serie. 3. Only one chapter of each series is shown in list 400.
4. Si el usuario hubiese consumido todas las temporadas y capítulos disponibles asociados a cada temporada de un catálogo bajo demanda (ej. Empezó en la temporada 1-episodio 1 y el último disponible era el 12 de la temporada 3) y, hubiera un capítulo de esa serie en un canal tradicional, pero de tres temporadas en adelante (ej. en el canal están emitiendo el episodio 4 de la temporada 6) se le mostrará al usuario en la lista 400 de contenidos multimedia similares, pero cuando lo seleccione, se le mostrará un aviso (auditivo y/o visual) superpuesto para que esté al tanto de que verlo podría suponer la revelación de detalles importantes (aviso antispoiler).  4. If the user had consumed all available seasons and chapters associated with each season of a catalog on demand (eg it started in season 1-episode 1 and the last one available was 12 of season 3) and, there would be a chapter of that series on a traditional channel, but from three seasons onwards (eg on the channel they are broadcasting episode 4 of season 6) the user will be shown in the list 400 of similar multimedia content, but when selected, will show you an overlay (auditory and / or visual) superimposed so that you are aware that seeing it could mean revealing important details (antispoiler notice).
5. Al igual que en el punto 2 si en un canal estuviesen echando el episodio 3 de la temporada 1 y en VoD está disponible desde la temporada 2 en adelante, en la lista 400 de contenidos multimedia similares se mostraría el episodio 1 de la temporada 2 pero avisando al usuario de ese salto en la historia.  5. As in point 2 if a channel were broadcasting episode 3 of season 1 and in VoD it is available from season 2 onwards, the episode 400 of similar multimedia content would show episode 1 of the season 2 but notifying the user of that jump in history.
6. Si el usuario empezó a ver una serie de emisión semanal desde el primer episodio de la primera temporada y se pierde algún capítulo de las semanas sucesivas y se le muestra como contenido multimedia relacionado un episodio más avanzado, también se avisará del salto. Adicionalmente, se comprobará si el capítulo que se ha perdido está disponible como contenido multimedia bajo demanda y se le mostrará como contenido multimedia similar. 7. Preferiblemente, para las series de comedia, que tienen una duración inferior a 35 minutos no aplican estas reglas ya que se considera que, a nivel general, son series de las que el usuario podría ver capítulos sueltos sin que afecte de una manera drástica al disfrute de la historia. La invención propuesta puede implementarse en hardware, software, firmware o cualquier combinación de los mismos. Si se implementa en software, las funciones pueden almacenarse en o codificarse como una o más instrucciones o código en un medio legible por ordenador. 6. If the user started watching a weekly broadcast series from the first episode of the first season and a chapter of the following weeks is lost and a more advanced episode is shown as related multimedia content, the jump will also be notified. Additionally, it will be checked if the chapter that has been lost is available as multimedia content on demand and will be shown as similar multimedia content. 7. Preferably, for comedy series, which have a duration of less than 35 minutes, these rules do not apply since it is considered that, on a general level, they are series from which the user could watch single chapters without affecting drastically To enjoy history. The proposed invention can be implemented in hardware, software, firmware or any combination thereof. If implemented in software, the functions can be stored in or encoded as one or more instructions or code in a computer-readable medium.
