    DESCRIPTION
    System for projecting immersive audiovisual content OBJECT OF THE INVENTION
    The present invention relates, in general, to the technologies of reproduction and projection of audiovisual content.
    More particularly, the present invention relates to a player-projector system for displaying immersive audiovisual content in real spaces, which offers complete visual coverage in the audiovisual content space ranging from 180 ° to 360 ° around the user.
    BACKGROUND OF THE INVENTION
    In the simulation of fictional actions and spaces (immersive technology) in the real world, immersive content or videos ("Immersive Content" in English) are also known, also called spherical or 360 ° videos. Normally these videos reproduce a panorama of a scenario, which can be real, that is done by recording the view of the stage in all possible directions at the same time by means of an omnidirectional camera or a collection of cameras, or virtual, which is done using 3D creation software. Immersive content is increasingly used in marquetin or advertising to attract more consumers and create a "hook" with them to "live" the sensations of products and services. They are also used in musical shows, theater, concerts, etc. to reach more public without the need to be present at the event, in the recreational sector of video games and in the education sector.
    In addition to 360 ° video recording, immersive content production techniques require specific post-production and three-dimensional (3D) animation software, requiring computer applications that allow the projection of equirectangular, cylindrical, stereographic images, fisheye, by cubic projection mapping, etc.

    There are currently many companies working on the creation of 360 ° audiovisual content. Companies like GoPro, Koloreyes, Unity3D, etc., actively develop this type of content, and other companies such as YouTube or Facebook develop online platforms for storage and playback in a browser. But although these contents are in full expansion, there is an imbalance between immersive content production techniques and immersive content reproduction techniques.
    A known technique of immersive content reproduction is the one used in Domes or Planetariums but it is a very expensive technique, so it is only applied in exceptional events, it is not viable for an individualized use.
    The most widespread and unique accessible immersive content reproduction technique, to date, on a personal level is the use of virtual reality (VR) glasses. These glasses, however, only allow the content to be enjoyed by the person who puts them on, isolating them from their real surroundings.
    An existing solution is that contemplated in WO 2012/118769, which describes an environment for the projection of videogame images that surrounds the user / player to submit it to an individual immersive experience. For this, the system has several projectors, conventional 2D image projectors such as a plasma TV screen, and 3D projectors, including an RGB projector that provides a peripheral image around that projector. However, WO 2012/118769 does not describe anything about what technical means get that projector, dubbed "environmental" in WO 2012/118769 to provide that 360 ° projection. On the other hand, WO 2012/118769 indicates that for the user to obtain the immersive 3D experience within that image projection, he wears a device (helmet or glasses) configured to operate in synchronization with all the projectors that make up that system. The WO 2012/118769 system also needs to be synchronized with the user's movements for its application in an environment of players that interact with the images of the video game, which restricts both the format of the audiovisual content that is presented and the role of the user in that immersive experience, where he plays an active role that requires the system techniques such as head tracking, the area of optimal position ("head tracking", "sweet-spot", ...).

    The objective technical problem that arises is thus to provide a projector-player to visualize immersive audiovisual content, with a visual coverage of 180 ° to 360 °, in real spaces, for a user or a large group of users, without the need of any other device.
    DESCRIPTION OF THE INVENTION
    The present invention serves to solve the problem mentioned above, solving the problems presented by the solutions mentioned in the state of the art, by means of a system configured to project audiovisual contents through a single compact player-projector device, without accessories (glasses, depth cameras, ...). The contents can be immersive or non-immersive and can be obtained from a content platform connected to the Internet (online).
    The present invention relates to a system adapted to reproduce and project the standard format (equirectangular projection) of immersive graphic content and also capable of adapting non-immersive content, both high definition digital (HD: "High Definition", FullHD,. ..) as an analog (NTSC standard: National Television System Committee, ...), to immersive projection, through processes and graphic animations.
    One aspect of the invention relates to a system of projection of audiovisual contents, which can be immersive as non-immersive, comprising a player-projector, which is a compact device and comprising the following components:
    - at least one control module which, in turn, comprises:
    - at least one wireless communication interface to communicate with a mobile user terminal,
    - Internet connection
    - communication interfaces to transmit at least one projector the audiovisual content obtained through the Internet, content from at least one server, its own or from third parties:
    - at least one immersive content projector and a non-immersive content projector connected to the control module via at least one of the aforementioned communication interfaces;

    - at least one audio module connected to the control module to reproduce the sound of the audiovisual contents transmitted by the control module to the content projectors.
    The advantages of the present invention with respect to the state of the art are fundamentally:
    - It is a compact product (all-in-one: "all in one"), easy to install (plug & play: "plug and play"), for personal or shared use, and affordable even at the domestic level. It adapts to most indoor domestic spaces without the need for works or renovations.
    - It allows to personalize the user experience through immersive, interactive and informative content, transforming the space to live that experience in a shared / collective way and not individual, without needing other devices for the reproduction of experiences.
    - The system is also capable of controlling domotic aspects (lighting, curtains, etc ...) and electrical / mechanical objects of the space where it is installed, using its own hardware, coordinating as a whole the different elements to enable the transformation of the physical space to user will This allows an extended immersion, that is, a perceptual impression of immersion extended by the synchronized home control of lights (colors and intensity), audio and automated furniture (curtain opening / closing, bed tilting / movement, ...) .
    - The system is connected to the internet, making it possible to display real-time data from different sources and project it in an immersive environment generated by projections. It also incorporates hardware and software components that allow the user to interact with the content, through different means (through a smart mobile phone of the user, by voice and / or user gestures, etc.).
    - Additionally, the system allows the user an interactive navigation through the projected space in 180 ° or 360 ° in real time. The immersive projection offered by the system becomes meaningful when the user can navigate in the 360 ° universe to emulate a point and field of view. Navigation can be done in a friendly way using the user's mobile phone or tablet, taking advantage of the facilities of the touch screen and the gyroscope of your terminal. The parameters for 360 ° navigation imply an infinite horizontal rotation and an invariable vertical rotation, as well as the possibility of zooming in / out (zoom functionality) in the projected images.

    using depth cameras, a gestural navigation is possible, allowing the control by means of gestures for example with the incorporation of a Kinect module.
    - With respect to the system described in WO 2012/118769 cited in the prior art, the present invention leaves the user more freedom and being a passive spectator if he wishes, since it is not necessarily a system for a video game environment. WO 2012/118769 that specifically deals with video game environments (gaming, in English) only considers immersive experiences of an individual, while the present invention contemplates the possibility of collective immersive experiences, of multiple users within the projected space, The present invention also offers the user connectivity to the Internet cloud (Internet Cloud, in English) and interaction with the system through their mobile phone. The system of the invention adapts to that user's terminal, without having to modify it. As for the projectors, in the system of the invention no spatial or temporal continuity is required between the projectors (one is not the continuation of the other, as occurs in WO 2012/118769). but they provide independent content: one is a non-immersive or “informative” content projector and the other constitutes an “environmental” projector with immersive content. In addition, WO 2012/118769 corrects the geometry of the images based on perspective and color correction, while in the present invention the distortion of an equirectangular image is counteracted, thanks to the fisheye lens , in English) included in the “environmental” immersive content projector. In WO 2012/118769, the projected audiovisual content is entirely and specifically produced for the gaming device, so its solution does not adapt to pre-existing content in common formats; on the contrary, the system of the invention is designed to reproduce standard formats (equirectangular, HD, etc.). Additionally, the option given by the present invention that the system has a home automation operation is not provided in WO 2012/118769.
    The present invention can be applied to the following sectors, to name a few examples:
    - Hotel and tourism sector: ideal for hotel rooms.
    - Leisure and catering sector: ideal for unique corners in restaurants and music bars.
    - Health sector: ideal for hospital rooms and other areas (sensory delivery rooms).
    - Trade sector: ideal for creating experiences around brands and product exposure.

To correct the geometry of the images and adapt them to an immersive projection, the following methods are performed:
    - For 360 ° / 180 ° equirectangular content, it is projected with the original geometric distortion provided. During the reproduction, the section of the 360 ° image to be projected is selected and the equirectangular projection is counter-subtracted, canceled, by the final distortion of the fisheye conversion lens (20).
    - For hemispheric content, the geometric distortion provided by the projection is canceled out by the final distortion of the (20) fisheye conversion.
    - For non-immersive content, a geometric correction of fisheye to planar is made using bezier curves.
    Additionally, the player-projector device can include a self-calibrator to detect surfaces automatically and adjust the projection of the images in real time to the detected surfaces.
    Another possible realization of the invention consists in joining two or more reproductive-projection devices, which are placed in the center of the room, to achieve an immersive projection of 360 ° horizontally, instead of only 180 ° horizontally.
