DESCRIPCION DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La sala de cine de nueva invención esta dotada de un video proyector automático, que forma las imágenes en la pantalla a partir de la combinación de tres colores rojo, azul, verde, que al combinarse y sumarse forman toda la gama de posibles colores. Estos tres focos luminosos que están en la propia sala, reciben las ordenes para su correcto funcionamiento, a través de señales electromagnéticas o digitales que le llegan por cable, o por fibra óptica o por ondas herzianas a través de una antena. Las señales electromagnéticas recibidas contienen toda la información necesaria; esto es la crominancia (que puntos de color deben iluminarse en un momento dado rojo, verde y azul) y la luminancia (Con que intensidad deben iluminarse cada uno de los puntos); ademas contiene la información de sincronismos tanto verticales como horizontales que hacen posible la formación de la imagen en la pantalla.The movie theater of new invention is equipped with an automatic video projector, which forms the images on the screen from the combination of three colors red, blue, green, which when combined and added together form the entire range of possible colors. These three light bulbs that are in the room itself, receive the orders for proper operation, through electromagnetic or digital signals that arrive by cable, or by optical fiber or by Herzian waves through an antenna. The received electromagnetic signals contain all the necessary information; this is the chrominance (what color points should be illuminated at a given time red, green and blue) and the luminance (How intensely each of the points should be illuminated); It also contains the information of both vertical and horizontal synchronisms that make possible the formation of the image on the screen.
La sala de cine de nueva invención , consta de una nave rectangular, cuya pared frontal es una pantalla blanca, en hileras paralelas a lo largo de la sala se sitúan las localidades o asientos formando filas con pasillo central, por donde circula el publico. A una distancia conveniente de la pantalla, según la lente del proyector y el diámetro de dicha pantalla se encuentra el proyector colgado del techo en un nicho anclado sobre un soporte hidráulico autónomo y automático, este esta unido mediante un cable coaxial a la fuente de recepción de la información, antena o terminal de fibra ópticaThe movie theater of new invention, consists of a rectangular nave, whose front wall is a white screen, in parallel rows along the room are located localities or seats forming rows with central aisle, through which the public circulates. At a convenient distance from the screen, depending on the lens of the projector and the diameter of the screen is the projector hanging from the ceiling in a niche anchored on an autonomous and automatic hydraulic support, this is connected by a coaxial cable to the source of information reception, antenna or fiber optic terminal
Un cine asi instalado funciona automático sin necesidad de la presencia física de la copia de proyección; sin necesidad de cabina independiente de proyección y sin necesidad de proyeccionista, que maneje la copia, la manipule, la coloque en el proyector y vigile la proyección.A cinema thus installed works automatically without the need for the physical presence of the projection copy; without the need for an independent projection booth and without the need for a projectionist, to handle the copy, manipulate it, place it in the projector and monitor the projection.
El interés de la invención viene dado porque la presencia física de la copia,o film no es necesaria; esta puede estar proyectándose leyéndose y transformando sus imágenes fotográficas, (los miles de fotogramas que componen dicha película, 24 cada segundo en una instalación distinta y alejada geográficamente) en impulsos digitales o analógicos obtenidos a través de un escaner de cada uno de los fotogramas que componen dicha película generando dicha acción de escanear una información de señales video magnéticas que son enviadas por cualquiera de los medios descritos cable, fibra óptica, o ondas herzianas a cada uno de los cines conectados a la red. Con el consiguiente ahorro tanto de copias, se utiliza una sola para tantos cines como se quiera, ahorro de transporte , manipulación, deterioro de copias (el cable transporta la señal de video) ahorro de personal, no es necesario el proyeccionista pues la proyección es automtica en cada una de las salas.The interest of the invention is given because the physical presence of the copy, or film is not necessary; this may be projected by reading and transforming its photographic images, (the thousands of frames that make up that film, 24 every second in a different and geographically remote installation) into digital or analog impulses obtained through a scanner of each of the frames that they compose said film generating said action of scanning an information of magnetic video signals that are sent by any of the described means cable, fiber optic, or herzian waves to each of the cinemas connected to the network. With the consequent saving of both copies, only one is used for as many cinemas as desired, transport savings, handling, deterioration of copies (the cable carries the video signal) personnel savings, the projectionist is not necessary as the projection is automatic in each of the rooms.
Por el lector de información o escaner situado en el laboratorio, pasa la copia plástica de la película o film deteniendo cada fotograma 1/ 25 de segundo, tiempo necesario para que el escaner efectué una lectura digital de la información cromatica del mismo convirtiendo esta en una señal de video o bit que contiene la información necesaria de crominancia (que puntos de color rojo verde y azul deben iluminarse) y la luminancia (con que intensidad debe iluminarse), esta señal llega al proyector de cada sala accionando la proyección de los tres colores que producen la imagen sobre la pantalla del cine y puede ser vista por los espectadores. Through the information reader or scanner located in the laboratory, pass the plastic copy of the film or film stopping each 1/25 second frame, time necessary for the scanner to make a digital reading of the chromatic information of the same turning it into a video or bit signal that contains the necessary chrominance information (which red and green red points should light) and the luminance (with what intensity should be illuminated), this signal reaches the projector of each room by activating the projection of the three colors that produce the image on the cinema screen and can be seen by the spectators.
