Abstract

The invention relates to systems and devices which are used for the creation, distribution and projection of contents in an interactive network of high-resolution screens or digital cinemas. The invention comprises a programming terminal (1) which transmits files to the content server (2) which in turn stores the files and transmits same to the satellite provider (3) where said files are encapsulated and encoded for transfer to the satellite (4). The aforementioned satellite distributes the signal over parabolic antennas (5) at cinemas, which transfer the signal to the tuner card of a local server (6). Subsequently, said local server decodes the archives and sends same to the digital projector (7) which projects the image using three colours (RGB). The inventive system also makes use of a failure and incident control line (8) which is used to ensure correct reception of the data sent by the satellite (4) at the local server (6) and an ADSL line (9) which transmits orders and packets in non-real time at 2 Mb/s by means of a control centre (10).

SECTOR DE LA TÉCNICASECTOR OF THE TECHNIQUE
La presente invención se refiere a los aparatos, sistemas y procedimientos necesarios para crear una red de cines digitales, cuyo funcionamiento implica el envío de archivos y señales de alta definición vía satélite, con los adecuados controles de recepción y gestión, todo ello con unos costes reducidos, tanto en lo que afecta a su implantación en las distintas salas cinematográficas o teatros provistos de la tecnología necesaria, fundamentalmente constituida por un proyector de alta resolución y un servidor capaz de gestionar y reproducir archivos de alta definición, como también a lo que se refiere a su posterior funcionamiento. ESTADO DE LA TÉCNICAThe present invention relates to the apparatuses, systems and procedures necessary to create a network of digital cinemas, whose operation involves the sending of files and signals of high definition via satellite, with the appropriate controls of reception and management, all with some costs reduced, both in terms of its implementation in the different cinemas or theaters equipped with the necessary technology, mainly constituted by a high-resolution projector and a server capable of managing and reproducing high definition files, as well as what is refers to its subsequent operation. STATE OF THE ART
La patente española n° 9700628, titulada: "Cine de proyección electrónica vía satélite", propiedad del mismo solicitante, abrió un primer camino para la creación de una red de cines electrónicos, en los cuales la gran ventaja es, sobre todo, el ahorro que supone el poder proyectar en los cines las películas sin necesidad de tener que realizar copias de celuloide de alto coste, como exige la exhibición por el sistema de cine tradicional. La patente de adición n° 9800628, titulada: Mejoras y perfeccionamiento que se introducen a la patente de invención n° 9700628 de fecha 21 de marzo 1997: "Cine de proyección electrónica vía satélite", también del mismo solicitante, propone un procedimiento para la captura, transporte, almacenamiento y proyección de imágenes de alta resolución en los cines electrónicos o cines digitales; este sistema se basa en la captura parcial y fragmentada de la realidad o imagen a capturar, su almacenamiento y transporte fragmentado, y emisión o proyección fragmentada y recompuesta del mosaico total mediante sistemas ópticos en la pantalla.The Spanish patent n ° 9700628, entitled: "Cinema of electronic projection via satellite", property of the same applicant, opened a first path for the creation of a network of electronic cinemas, in which the great advantage is, above all, savings that supposes the power to project the movies in the cinemas without having to realize copies of celluloid of high cost, as it demands the exhibition by the system of traditional cinema. The patent of addition n ° 9800628, entitled: Improvements and improvements that are introduced to the patent of invention n ° 9700628 dated March 21, 1997: "Cinema of electronic projection via satellite", also from the same applicant, proposes a procedure for the capture, transportation, storage and projection of high resolution images in electronic cinemas or digital cinemas; this system is based on the partial and fragmented capture of the reality or image to be captured, its storage and fragmented transport, and emission or fragmented projection and recomposed of the total mosaic by means of optical systems on the screen.
La presente invención parte de los actuales avances tecnológicos en los procesadores que llegan a superar los 3 gigaherzios y en los proyectores digitales que en la actualidad tienen procesadores y sistemas para formar las imágenes a través de la combinación de los tres colores rojo, verde y azul en sus chip, bien sean LCD, TFT, DLP, D-LLA o láser, con resoluciones que superan los 2000x2000 píxeles y luminosidades de hasta 17000 ANSÍ LUMEN, que superan con mucho lo requerido por una sala de cine normal. Estos avances permiten que ya no sea necesario utilizar el sistema de imagen fragmentada y mosaico descrito en las citadas anterioridades de patente para las salas de cine y solo sería necesaria su utilización en los casos extremos donde se requirieran pantallas de más de 100 metros, como un estadium donde se necesitara recomponer imágenes de altísima resolución y altísima luminosidad.The present invention is based on current technological advances in processors that exceed 3 gigahertz and digital projectors that currently have processors and systems to form the images through the combination of the three colors red, green and blue on their chip, whether they are LCD, TFT, DLP, D-LLA or laser, with resolutions that exceed 2000x2000 pixels and luminosities of up to 17,000 ANSÍ LUMEN, which far exceed what is required by a normal movie theater. These advances allow that it is no longer necessary to use the fragmented and mosaic image system described in the aforementioned patents for movie theaters and it would only be necessary to use them in extreme cases where screens of more than 100 meters are required, such as estadium where it will be necessary to recompose images of high resolution and very high luminosity.
Para los casos normales de cines donde las pantallas apenas superan los 15 metros y las condiciones de luz son normales, la invención ahora propuesta resuelve con unos costes muy reducidos la calidad de imagen necesaria y adecuada. El proceso creador del hombre tiene la constante de inventar aparatos y procedimientos que le ayuden en su afán por superar las barreras espacio temporales que le limitan. El hombre quiere estar en todas partes y ver lo que ocurre en cualquier lugar en tiempo real. Los medios de comunicación nos ayudan a esto, pero aquellos medios en los que continente y contenido muestran una gran dependencia están perdiendo competitividad; como así sucede con el cine, cuyo contenido (historia) va íntimamente ligado al continente (soporte de celuloide); el libro, las cartas, etc. todos ellos, dependientes de un soporte físico, que les quita movilidad y les hace copiables, facilitando así, la burla f audulenta de los derechos de autor.For the normal cases of cinemas where the screens barely exceed 15 meters and the light conditions are normal, the invention now proposed resolves with very low costs the necessary and adequate image quality. The creative process of man has the constant invent devices and procedures that help him in his eagerness to overcome the temporary space barriers that limit him. Man wants to be everywhere and see what happens anywhere in real time. The means of communication helps us to this, but those media in which continent and content show great dependence are losing competitiveness; as it happens with the cinema, whose content (history) is intimately linked to the continent (celluloid support); the book, the letters, etc. all of them, dependent on a physical support, that removes mobility and makes them copyable, thus facilitating the mockery of the author's copyright.
Sistemas más directos, como la televisión, el teléfono móvil, Internet, dan una sensación de vivir el momento presente, en vivo y en directo. El publico cada vez busca más esta sensación; teatro, fútbol, eventos en vivo. El cine, que tenía perdida la carrera por culpa del celuloide, con la presente invención puede recuperar su liderazgo, al convertir las pantallas gigantes de las salas de cine, en un elemento vivo, seguro, directo e interactivo. EXPLICACIÓN DE LA INVENCIÓNMore direct systems, such as television, mobile phone, Internet, give a feeling of living in the present moment, live and direct. The public increasingly seeks this feeling; theater, football, live events. The cinema, which had lost the race because of the celluloid, with the present invention can regain its leadership, by turning the giant screens of movie theaters, into a living, safe, direct and interactive element. EXPLANATION OF THE INVENTION
Los aparatos y procedimientos necesarios para la creación de una red interactiva de cines digitales, según la nueva invención ahora preconizada son: Un servidor central, con dos procesadores de alta potencia, del tipo Pentium IV o similar, para el almacenamiento general con acceso tanto a eventos en directo, como a películas y publicidad, almacenados en forma de archivos que han sido previamente convertidos en program stream, o bien transport stream mediante algoritmos de compresión y codificación ya conocidos de la familia Jpeg 2000, Mpeg 2, o bien Mpeg 4, QPE (Quality Priority Encoding) o cualquier otro que nos permita prescindir de la información redundante y de la no apreciable por el ojo humano, mediante software del tipo Ligos, Windows Media Player 9, Elecar o cualquier otro; o mediante hardware con aparatos y tarjetas PCI que permiten esta codificación en tiempo real, como los HD encoder utilizados por las HDTV stations, que realizan codificaciones a 20 Megabit por segundo en los formatos ATSC o DVB ASI, o la tarjeta 120 PCI Encoder de DUMA que realiza esta codificación en tiempo real creando un archivo program stream con el sonido embebido en 5.1, AC3 o cualquier otro.The apparatuses and procedures necessary for the creation of an interactive network of digital cinemas, according to the new invention now recommended are: A central server, with two high-power processors, of the Pentium IV type or similar, for general storage with access to both live events, such as movies and advertising, stored in the form of files that have been previously converted into program stream, or transport stream using compression and coding algorithms already known from the Jpeg 2000 family, Mpeg 2, or Mpeg 4, QPE (Quality Priority Encoding) or any other that allows us to dispense with redundant information and that which can not be appreciated by the human eye, through software such as Ligos, Windows Media Player 9, Elecar or any other; or through hardware with devices and PCI cards that allow this encoding in real time, such as the HD encoder used by the HDTV stations, which perform encodings at 20 Megabit per second in the ATSC or DVB ASI formats, or the DUMA 120 PCI Encoder card that realizes this coding in real time. a program stream file with the sound embedded in 5.1, AC3 or any other.
Este servidor central, estaría formando una red virtual con los distintos ordenadores colocados en cada uno de los cines esclavos instalados. Partiendo del expuesto esquema del sistema preconizado, su empleo puede realizarse respecto a contenidos que pueden venir de la realidad viva, esto es: un evento, una representación de opera, una obra de teatro, conciertos, toros, etc.. que están ocurriendo en un escenario de una sala de teatro, o en cualquier otro lugar donde el público se concentra para ver un espectáculo. En este caso los dispositivos captadores de imagen y sonido, se situarán estratégicamente frente al escenario, o lugar donde ocurre la acción, dándonos el plano general y los distintos planos, que capten la acción en vivo y en directo; estos dispositivos pueden ser CCD, sea Cmos o cualquier otro que permita obtener con una alta resolución 2K o similar toda la información de cada uno de los colores RGB o sus complementarios y su luminancia. La información, sea analógica o digital, con un ancho de banda grande, será procesada, codificada y comprimida, mediante algoritmos, ya conocidos de la familia Jpeg 2000, MPEG2 o bien MPEG4; esa codificación y compresión, que eliminará información redundante, se realizará en la propia cámara, si está dotada de un ENCODER por hardware, o por software tipo Windows Media Player 9 Encoder o cualquier otro, hasta obtener flujos de datos de unos 8 ó 9 MB/s en MPEG4, ó bien 19 a 20 MB/s en MPEG2; para su posterior transporte a las pantallas de exhibición. En el caso de una representación en escenarios naturales, o bien de la grabación en vivo y directo de una película, serie, etc., las distintas escenas o secuencias estarán planificadas para emplear tantas cámaras o elementos captadores como el realizador crea necesario para su mejor expresión artística. Cada cámara entregará un flujo de información o sfreaming independiente, o bien la mesa de mezclas de la unidad o control central realizará dicha codificación solamente del elemento captador o cámara seleccionado por el realizador, siendo este flujo de información el que se transporte hasta los espectadores. Si la creación del contenido, se realiza de una obra previamente grabada en otro formato, sea celuloide o tape digital o analógico, se efectuará, en el primer caso, la lectura de la información cromática, contenida en cada uno de los fotogramas, mediante un escáner o un telecine de alta resolución; los datos obtenidos de esa lectura, etalonados y corregidos en cuanto a su colorimetría, adecuadamente, se comprimen y codifican por hardware o software, hasta crear un archivo en MPEG2 MP@HL con el audio embebido en AC3 (5+1) o bien en MPEG4; dicho archivo se almacena en el servidor central, para su posterior multiplexado, encriptado y envío a la red de servidores, con direcciones LP, de las salas de exhibición, mediante una descarga de datos, por cable, ADSL, fibra óptica, o cualquier otro a través de multicast o unicast; o bien puede hacerse mediante broascast, por satélite o por vía digital terrestre, captando las señales a través del sintonizador incorporado en los servidores locales. En el caso de que el contenido esté soportado en otro formato Tape o disco duro, entonces será necesaria su lectura, codificación y multiplexado a través de cualquier encoder HD o a través de cualquier tarjeta PCI que codifique MPEG 2, ó MPEG 4, en HD, como por ejemplo, la tarjeta codificadora DI HD Encoder, de Duma Video, que entrega un archivo ya creado y codificado.This central server, would be forming a virtual network with the different computers placed in each of the slaves installed cinemas. Starting from the outlined scheme of the proposed system, its use can be made with respect to contents that may come from the living reality, that is: an event, an opera performance, a play, concerts, bulls, etc. that are occurring in a stage of a theater hall, or any other place where the audience concentrates to see a show. In this case, the image and sound capture devices will be strategically placed in front of the stage, or place where the action takes place, giving us the general plan and the different planes that capture the action live and direct; these devices can be CCD, either CMOS or any other that allows to obtain with a high resolution 2K or similar all the information of each one of the RGB colors or their complementary and their luminance. The information, analog or digital, with a large bandwidth, will be processed, encoded and compressed, using algorithms, already known from the Jpeg 2000 family, MPEG2 or MPEG4; that encoding and compression, which will eliminate redundant information, will be done in the camera itself, if it is equipped with a hardware ENCODER, or by software such as Windows Media Player 9 Encoder or any other, until obtaining data flows of about 8 or 9 MB / s in MPEG4, or 19 to 20 MB / s in MPEG2; for later transport to the exhibition screens. In the case of representation in natural settings, or live and direct recording of a film, series, etc., the different scenes or sequences will be planned to use as many cameras or capturing elements as the director believes necessary for its best artistic expression. Each camera will deliver an independent information flow or sfreaming, or else the mixer of the unit or central control will perform said coding only of the sensor element or camera selected by the director, this information flow being transported to the spectators. If the creation of the content is made of a work previously recorded in another format, be it celluloid or digital or analogue tape, in the first case, the reading of the chromatic information, contained in each of the frames, will be made through a scanner or a high-resolution telescope; the data obtained from that reading, graded and corrected in terms of their colorimetry, are suitably compressed and encoded by hardware or software, to create a MPEG2 MP @ HL file with the audio embedded in AC3 (5 + 1) or in MPEG4; said file is stored in the central server, for its subsequent multiplexing, encryption and sending to the network of servers, with LP addresses, of the exhibition halls, by means of a data download, by cable, ADSL, fiber optic, or any other through multicast or unicast; or it can be done by broascast, satellite or digital terrestrial, capturing the signals through the tuner built into the local servers. In the event that the content is supported in another format Tape or hard disk, then it will be necessary to read, encode and multiplex through any HD encoder or through any PCI card that encodes MPEG 2, or MPEG 4, in HD, as for For example, the HD HD encoder card Encoder, from Duma Video, which delivers an already created and encoded file.
Los contenidos, una vez en forma de archivos, se encuentran almacenados en el servidor central del centro de control, junto con los terminales de programación; en el caso de eventos en diferido u obras grabadas, cada teatro, o sala o pantalla está dotada de un terminal o servidor local con su dirección LP, que se controla remotamente por Internet y recibe los archivos que se le envían por una descarga de datos mediante protocolos TCPLP, a través de la tarjeta receptora de datos por satélite, red local o mediante la tarjeta sintonizadora del servidor local, tipo SkyStar 2 TV de Technisat, que permite sintonizar televisión vía satélite y también recibir datos por satélite; el servidor local almacena, administra, decodifíca por hardware o software y envía las señales al proyector al que se encuentra unido mediante un cable, cuyas imágenes son proyectadas sobre la pantalla, formando así las imágenes de los archivos que se encuentran almacenados en el servidor central. El transporte es simple si unimos los distintos servidores mediante una red privada o pública a través de cable, ondas herzianas, antenas de satélite o cualquier otro que nos permita un ancho de banda suficiente de unos 20 MB/s, si codificamos en MPEG2, y unos 9 MB/s si codificamos enMPEG4.The contents, once in the form of files, are stored in the central server of the control center, together with the programming terminals; in the case of deferred events or recorded works, each theater, or room or screen is equipped with a terminal or local server with its LP address, which is remotely controlled by Internet and receives the files sent to it by a data download through TCPLP protocols, through the satellite receiver card, local network or through the tuner card of the local server, type SkyStar 2 TV by Technisat, which allows tuning satellite television and also receiving satellite data; the local server stores, manages, decodes by hardware or software and sends the signals to the projector to which it is linked by a cable, whose images are projected on the screen, thus forming the images of the files stored in the central server . The transport is simple if we join the different servers through a private or public network through cable, Herzian waves, satellite antennas or any other that allows us a sufficient bandwidth of about 20 MB / s, if we encode in MPEG2, and about 9 MB / s if we encode in MPEG4.
Creada esa red virtual los protocolos de comunicación pueden ser propios, o mejor protocolos universales TCPIP; cada uno de los terminales estará dotado de un router, con una dirección IP pública. Con una red así creada mantendremos una conexión permanente con el servidor central.Created that virtual network the communication protocols can be their own, or better TCPIP universal protocols; Each of the terminals will be equipped with a router, with a public IP address. With such a network we will maintain a permanent connection with the central server.
Los envíos de los archivos se realizarán mediante multicast a todas y cada una de las direcciones LP de los servidores locales, o mediante envíos broadcast, para ser captados por los sintonizadores de las distintas antenas receptoras.The files will be sent by multicast to each and every one of the LP addresses of the local servers, or through Broadcasts, to be picked up by the tuners of the different receiving antennas.
Los software propietarios permiten controlar todos los dispositivos de descarga, envío de paquetes, confirmación, detección de errores, averías y desencriptación.The proprietary software allows to control all the devices for downloading, sending packages, confirming, detecting errors, faults and decryption.
Las distintas pantallas o teatros se encuentran unidas en red al servidor central, mediante cable (ADSL, teléfono, red eléctrica, fibra óptica, etc.), o sin cable, mediante ondas hertzianas (satélite, antena terrestre, etc.). Estas uniones o tuberías de datos, nos permiten envíos constantes de información bidireccional: en sentido servidor central a servidores locales o descarga, el ancho de banda requerido es mayor, de unos 20 Mgb/s, y se utiliza para los eventos en directo, o la descarga rápida de archivos; el canal de retroceso, desde los servidores locales al servidor central, será de un ancho de banda menor, pues solo se utiliza, para el envío de peticiones de control, o para controlar los distintos dispositivos de la sala, como las cámaras digitales, situadas encima de la pantalla de cada sala, dirigidas hacia el patio de butacas, que nos ofrecen la imagen de los espectadores con el fin de controlar la audiencia o asistencia en un determinado momento; estas cámaras pueden ser normales o bien, si se desea mayor detalle, de infrarrojos; la cámara que se encuentra unida por cable o por ondas al servidor local envía, cada periodo de tiempo, una fotografía digital, que almacena el servidor, junto a un temporizador visualizado. Cada pantalla está controlada y unida al servidor local del que recibe la información; éste está basado en una estructura de PC, constando pues, de una placa base, un procesador tipo Pentium o cualquier otro, memoria RAM incorporada, Tarjeta VGA, tarjeta de sonido, que decodifíque AC3, entrada de red local y tarjeta receptora de datos del satélite, tarjeta sintonizadora y decodifícadora basadas en el procesador TL 880 chip, o cualquier otro que permita decodificar y displayar HDTV; los discos duros podrán ser IDE; a modo de ejemplo algunas tarjetas que decodifϊcan por hardware: - QPE (Quality Priority Encoding) de Quvis. - Tarjeta Janus de Teralogic que permite descomprimir y decodifícar HD multiplexado según la norma ATSC, o DVB. - Procesador o tarjeta Trimedia HD de Philips. - Chips BSP-15 de la plataforma Tetra de Equator, que permite codificar y decodificar HD en MPEG2 o MPEG4.The different screens or theaters are linked in a network to the central server, by cable (ADSL, telephone, electrical network, optical fiber, etc.), or without cable, by means of hertzian waves (satellite, terrestrial antenna, etc.). These unions or data pipelines allow us to send constant bidirectional information: in a central server to local servers or download, the required bandwidth is greater, about 20 Mgb / s, and is used for live events, or fast file download; the backward channel, from the local servers to the central server, will be of a lower bandwidth, since it is only used for the sending of control requests, or to control the different devices in the room, such as digital cameras, located above the screen of each room, directed towards the stalls, which offer us the image of the spectators in order to control the audience or attendance at a certain moment; These cameras can be normal or, if you want more detail, infrared; the camera that is connected by cable or waves to the local server sends, each period of time, a digital photograph, which the server stores, together with a displayed timer. Each screen is controlled and linked to the local server from which it receives the information; This is based on a PC structure, consisting of a motherboard, a Pentium or any other processor, built-in RAM, VGA card, sound card, which decodes AC3, local network input and data receiver card. satellite, card tuner and decoder based on the TL 880 chip processor, or any other that allows decoding and displaying HDTV; the hard drives may be IDE; As an example, some cards decode by hardware: - QPE (Quality Priority Encoding) by Quvis. - Janus card from Teralogic that allows you to decompress and decode HD multiplexed according to ATSC, or DVB. - Processor or Philips Trimedia HD card. - BSP-15 Chips from Equator's Tetra platform, which allows encoding and decoding HD in MPEG2 or MPEG4.
Para realizar la decodifícación por software se empleará, entre otros decoder, cualquiera de Elecar si se desea en Mpeg2 o Windows Media Player si es en Mpeg4.

En la Figura 1 en que consiste el diagrama adjunto se ofrece un esquema de la disposición de los sistemas y aparatos que la presente invención combina para la creación, distribución y proyección de contenidos a través de una red interactiva de pantallas de alta resolución o cines digitales. Mediante esta Figura 1 puede contemplarse que el objeto de la presente invención se caracteriza por un terminal de programación (1) que incorpora el centro de control que envía los ficheros al servidor de contenidos (2), que es el equipo que almacena los contenidos y los canaliza hacia el proveedor de satélite (3) donde se encapsulan y codifican los contenidos para su subida al satélite (4) a 20 Mb/s, en el caso de eventos en directo y transmisión rápida, cuyo satélite es el que refleja la señal y la distribuye sobre las antenas parabólicas (5) de su huella, cada una de las cuales está instalada en el cine que recoge la señal y la traslada al servidor local (6) también instalado en el cine y que dispone de una tarjeta sintonizadora que capta la señal del satélite (4), decodifíca los archivos y los envía al proyector digital (7) que, a través de los tres colores (RGB) proyecta la imagen sobre la pantalla del cine; habiéndose previsto una línea de control de averías e incidencias (8), que permite controlar la correcta recepción en el servidor local (6) de los paquetes enviados a través del satélite (4), así como la utilización de una línea ADSL (9), la cual permite transmisión de órdenes y de paquetes en diferido a 2 Mb/s, todo ello mediante la utilización de un centro de control (10).To perform the software decoding, among other decoders, any of Elecar will be used if desired in Mpeg2 or Windows Media Player if it is in Mpeg4. DESCRIPTION OF THE ATTACHED DIAGRAM For a better understanding of the described functionality of the present invention, a diagram showing a preferred and non-limiting example of embodiment of the present invention is attached. Figure 1 in which the attached diagram consists of a scheme of the arrangement of the systems and apparatuses that the present invention combines for the creation, distribution and projection of contents through an interactive network of high resolution screens or digital cinemas . By means of this Figure 1 it can be seen that the object of the present invention is characterized by a programming terminal (1) that incorporates the control center that sends the files to the content server (2), which is the equipment that stores the contents and it channels them to the satellite provider (3) where the contents are encapsulated and encoded for uploading to the satellite (4) at 20 Mb / s, in the case of live events and fast transmission, whose satellite is the one it reflects the signal and distributes it over the parabolic antennas (5) of its footprint, each of which is installed in the cinema that collects the signal and transfers it to the local server (6) also installed in the cinema and which has a tuner card that captures the satellite signal (4), decodes the files and sends them to the digital projector (7) that, through the three colors (RGB), projects the image onto the cinema screen; having provided a fault and incident control line (8), which allows to control the correct reception in the local server (6) of the packages sent through the satellite (4), as well as the use of an ADSL line (9) , which allows transmission of orders and packages deferred to 2 Mb / s, all through the use of a control center (10).
El centro de control (10) está compuesto por un servidor central (1) en el cual están los distintos software de control de base de datos que permiten el control de la emisión, el control de abonados, el control de reproducción, el control de transmisión y el control de asistencia, entre otros.The control center (10) is composed of a central server (1) in which are the different database control software that allow the control of the broadcast, the subscriber control, the reproduction control, the control of transmission and attendance control, among others.
MODO DE REALIZACIÓN PREFERIDA DE LA INVENCIÓN Un modo de realización preferente de la invención ahora preconizada, que no limita ni excluye cualquier otra, sería a partir en la creación de contenidos de normas suficientemente conocidas, como son las señales de alta definición estándar, 1920 x 1080, que se obtienen fácilmente de un telecine HD Spirit o Rank Cintel, con opción salida HD, o cualquier HDCAM o D5, que almacena y lee HD sin dificultad; esa señal digital la convertimos en un archivo codificado y multiplexado en MPEG2, apto para ser transportado; la codificación la efectuaremos a 20 MB/s a través de cualquier encoder conocido, con el sonido AC3 embebido; si ese archivo contiene una información tipo película, que no necesita ser en vivo y en directo, se puede enviar por canales de banda normal ADSL, de 2MB/s, que aunque tarda 10 veces más, al ser tarifa plana, no supone ningún coste especial, o se puede enviar realizando una emisión broadcast, por satélite o digital terrestre en ATSC, o DVB ASI, en horarios de escasa utilización, como puede ser la noche.PREFERRED MODE OF EMBODIMENT OF THE INVENTION A preferred embodiment of the invention now recommended, which does not limit or exclude any other, would be from the creation of contents of sufficiently known standards, such as standard high definition signals, 1920 x 1080, which are easily obtained from a HD Spirit or Rank Cintel telecine, with HD output option, or any HDCAM or D5, which stores and reads HD without difficulty; that digital signal is converted into a file encoded and multiplexed in MPEG2, apt to be transported; the encoding will be done at 20 MB / s through any known encoder, with the embedded AC3 sound; If that file contains a movie-like information, it does not need to be in Live and live, it can be sent through normal band ADSL channels, of 2MB / s, which although it takes 10 times more, being flat rate, does not suppose any special cost, or it can be sent by broadcast, satellite or digital terrestrial in ATSC, or DVB ASI, in schedules of little use, such as night.
Los eventos en directo, se recogen mediante cámaras estándar de HD o cámaras de CMOS de alta resolución, capaces de efectuar streaming en tiempo real, que codificado pasaría directamente al elemento de transporte de la señal, con un ancho de banda mínimo de 20 MB/s y que puede ser mediante antenas de satélite que permiten Internet y comunicaciones con protocolos LP, o mediante emisiones broadcast efectuadas directamente desde el lugar del evento, a través de unidades móviles de transponder para el envío, mediante parabólicas, al satélite. Los contenidos o archivos, alojados en el servidor central, que hace las funciones de Web Server con direccionamiento IP pública, son enviados a los servidores locales que contienen las tarjetas decodifícadoras y su software correspondiente. Estos pueden acceder, vía Internet, al Web Server mediante carpetas compartidas, por la línea del Back control, que sería ADSL o línea telefónica de Internet, abriendo el archivo correspondiente que deseamos visionar, a través del archivo ejecutable cine digital, hacemos en el servidor central que la ruta de envío se realice mediante satélite con ancho de banda de 20 MB/s y así podemos visionar a través de la salida VGA de la tarjeta descompresora en RGB analógico conectado a la entrada VGA o RGBVΗ del proyector, la señal en alta definición, o pueden realizarlo mediante el proceso de Multicast o Broadcast ya descrito.The live events are collected by standard HD cameras or high resolution CMOS cameras, capable of streaming in real time, which encoded would go directly to the signal transport element, with a minimum bandwidth of 20 MB / sy and that can be by means of satellite antennas that allow Internet and communications with LP protocols, or by broadcast broadcasts made directly from the place of the event, through mobile units of transponder for sending, by satellite dishes, to the satellite. The contents or files, hosted on the central server, which makes the Web Server functions with public IP addressing, are sent to the local servers that contain the decoding cards and their corresponding software. These can access, via Internet, the Web Server through shared folders, by the line of the Back control, which would be ADSL or Internet telephone line, opening the corresponding file that we wish to view, through the executable file digital cinema, we do in the server central that the route of sending is made by satellite with bandwidth of 20 MB / s and so we can watch through the VGA output of the decompression card in analog RGB connected to the VGA or RGBVΗ input of the projector, the signal in high definition , or they can do it through the Multicast or Broadcast process already described.
Cuando esté disponible la utilización de las líneas de la red eléctrica para el transporte de datos, el sistema podría ser más simple, pues implementaríamos la red a través de los cables de la corriente eléctrica, disponibles en cada lugar. Esta red virtual, instalada en cada sala, podría ser utilizada para hablar por teléfono, desde locutorios instalados en el vestíbulo, a través de voz por LP. Los archivos pueden ser encriptados doblemente y la segunda llave de encriptación o encriptación Soft sólo se abriría desde el control central y sería cambiada a voluntad en cada envío.When the use of the lines of the electrical network for the transport of data is available, the system could be simpler, because we would implement the network through the electric current cables, available in each place. This virtual network, installed in each room, could be used to talk on the phone, from call centers installed in the lobby, through voice over LP. The files can be double encrypted and the second encryption key or Soft encryption would only be opened from the central control and it would be changed at will in each shipment.
En cualquier caso, según una realización preferida, el PC o servidor cliente ha de encontrarse alojado dentro del propio proyector; así se evitarían conexiones externas y, por tanto, posibles manipulaciones de la señal y los contenidos; el bloque proyector-PC sólo tendría una entrada de red local para conectar a Internet, modem, router, etc. Otra entrada de antena y otra entrada de corriente eléctrica; asimismo, tendría sólo las salidas del audio 5+1, que se conectaría a los amplificadores de la sala de cine, evitando así cualquier piratería o manipulación de los archivos de imagen, que solamente podrían ser visionados, desde el proyector a la pantalla. Desde el control remoto central el proyector seria manejado en todos y cada uno de sus parámetros y, desde allí, también serían manejados los distintos archivos a visionar, películas, publicidad, etc. Cuanto ha quedado descrito constituye un fiel reflejo de la presente invención, debiendo considerarse las características de la misma que han sido expuestas en sentido amplio y no limitativo, siendo indiferentes y cambiantes las circunstancias de carácter meramente formal, secundario o accesorio que no alteren la esencialidad que a continuación es reivindicada. In any case, according to a preferred embodiment, the PC or client server must be housed inside the projector itself; this would avoid external connections and, therefore, possible manipulations of the signal and the contents; the projector-PC block would only have a local network input to connect to the Internet, modem, router, etc. Another antenna input and another electrical power input; likewise, it would have only the outputs of the 5 + 1 audio, which would be connected to the amplifiers of the cinema, thus avoiding any piracy or manipulation of the image files, which could only be viewed, from the projector to the screen. From the central remote control the projector would be managed in each and every one of its parameters and, from there, the different files to be viewed, movies, advertising, etc. would also be handled. What has been described constitutes a faithful reflection of the present invention, having to consider the characteristics thereof that have been exposed in a broad and non-limiting sense, being indifferent and changing the circumstances of a merely formal, secondary or accessory nature that do not alter the essentiality which is then claimed.
