Title of Invention	CINEMA OF ELECTRONIC PROJECTION BY SATELLITE
Abstract	It consists of a facility fitted with an electronic projector unit that projects upon a screen three light emitting sources, red, green and blue, which combination is driven by electromagnetic signals (RGB or Video) received via satellite from a digital reader or scanner that transforms film frames into electronic data (chrominance and luminance) which condition the projection.

FIELD OF INVENTION This invention refers to a new type of cinemas fitted with an electronic projection system, that: forms images on the screen, through the combination of the colours red, green and blue. The signals that determine said RGB combination or video projection arrive to the cinema via cable, optical fibre or satellite, all of which produces a substantial saving and improvement in respect of both the projection and the physical distribution of films to these cinemas. BACKGROUND OF THE INVENTION The cinema projection system currently used in cinemas is based on the physical presence of a celluloid copy of the film that is to be projected, at the projection room of the movie house. The copy of the film must be physically collected from a warehouse, carried to the cinema where it is to be shown and, upon arrival at the projection room of the relevant cinema, it must then be prepared for projection by being fitted on the corresponding reels of two film projectors that are used alternatively, or else it may also be prepared for projection through its mounting, by splicing the film as needed, into a single large size reel, so that the whole film is then run through a single film projector. This projector is fitted with a powerful light source that projects white light on the screen, the film passes gradually the projection opening where each of the film frames is briefly stopped in front of the light beam during a length of time equal to 1/24th of a second, which makes it possible for the photographic image to be projected in full colour on the projection screen. -2- This type of facility at cinemas does therefore need:- a person to collect, transport to the cinema and later return to the film warehouse a physical copy of the movie to be projected. A projection room or similar facility acoustically insulated from the viewing theatre, so as to avoid that the noise that the projector makes whilst reeling the film may carry to the viewing theatre; - Two persons to supervise the projection procedure at the projection room, which would also splice the films as needed and fit the film reels upon the projectors. A cinema fitted with the projection system employed up to now would also require a copy of the film that is to be projected to be available at the film warehouse so that it may be used, as otherwise the cinema would have to wait until that particular film is available, causing its public to partly lose interest in the projection, and furthermore film copies wear out with use. DECRIPTION OF THE INVENTION The newly invented cinema is fitted with an automatic video projector, which forms the required images on the screen through the combination of the red, blue and green colours which, upon combining and mixing, form the whole gamut of all possible colours. These three light emitting sources located within the viewing theatre receive the necessary instructions for their proper operation by way of electromagnetic signals conveyed to it via cable, fibre optics or radio waves received via an antenna. The electromagnetic signals so received contain all necessary information; that is to say the chrominance (which colour spots are to light up in red, green or blue at a given time) and the luminance (with what level of intensity must each of said spots light up); they do furthermore contain the data required for the proper vertical and horizontal synchronisms that make it possible for the image to form on the screen. -3- The newly invented cinema is made up of a rectangular hall, which front wall is a white screen, whereas seats are located in parallel rows along the viewing hall leaving a central access aisle that allows the public to move around the hall. At a appropriate distance from the screen, which would depend on the lens used by the projector and on the diameter of the screen, would be located the projector unit hanging from the ceiling and placed within a housing niche firmly anchored to an autonomous and automatic hydraulic frame, which would also be joined, using a coaxial cable, to the data reception source, antenna or fibre optics terminal unit. A cinema house so fitted would function automatically without requiring the physical presence of a copy of the film to be projected: not needing an independent projection room and without a projection attendant to handle film reels, fit them on the projector and supervise the film projection process. The interest of this invention arises from the fact that the physical presence of a copy of the film to be projected is not required: it may be projecting, reading and so transforming its photographic images (the thousands of photographic frames that make up said movie, at a rate of 24 per second, at a different and geographically remote location) into digital or analogue impulses obtained by scanning each of the photographic frames that made up said film, whereas said scanning process would generate a series of magnetic video signals that are thereafter conveyed, using the already described cable, fibre optics or radio wave means to each of the cinemas linked to the network. This would bring about a saving in the number of film copies used, as a single one would be used for as many cinema houses as needed, further savings in respect of film copy transportation, handling and resulting wear and tear, the cable would convey the video signal; savings in respect of no longer required film projection attendants, as film projection would be automatic in each of the participating cinemas. -4- The celluloid copy of the film would be passed by the data reader or scanner located at the lab, stopping each photographic frame 1/25th of a second, length of time needed for the scanner to digitally scan the chromatic data contained therein, allowing it to be converted into a video signal that would then incorporate the required chrominance (which red, green and blue coloured spots are to light up) and luminance (with what level of intensity must they light up) data, which signal is conveyed to the projecting unit located at each viewing theatre, which subsequently project the three colours that make up the image upon the movie screen so that it may be watched by movie goers. -5- WE CLAIM : 1. A method of electronically projecting cinema via satellite comprising the steps of : issuing three coloured lights red, blue and green from an electronic projector located in front of a screen that responds to RGB electromagnetic or combined video impulses or signals containing data required for effecting their projection, using corresponding light emitting sources (CTR,LCD, DMD or LAZOR) for each such colour; and forming screened images through a combination of said three colours red, blue and green, projecting either jointly or separately, their light beams upon said screen,thus making up the moving images of a film. 2. The method of electronically projecting cinema as claimed in claim 1, wherein the video or data signals that contain the data that make the projection possible are obtained at a place other than the actual cinema house, where the photographic images printed on the film or frames are previously transformed into video or RSB signals, obtained by reading or scanning the chromatic data contained by the photographic emulsion of each of the frames of said film, the analog or digital signals, which condition the projection of the three colours in respect of their levels of chrominance and luminance, are conveyed to the cinemas using radio waves, cable, fibre optics or satellite signals. -6- 3. The method of electronically projecting cinema as claimed in claims 1 and 2, wherein the reading or replay of the video or RGB signals that contain the data that operates and conditions the electronic projection is effected at the actual cinema, given that it is fitted with a signal replay unit capable of reading and replaying the digital or analog signals stored in any kind of physical media, optical disk, magnetic disk, digital or analog tape. Dated this 23rd day of March,1998 -7- It consists of a facility fitted with an electronic projector unit that projects upon a screen three light emitting sources, red, green and blue, which combination is driven by electromagnetic signals (RGB or Video) received via satellite from a digital reader or scanner that transforms film frames into electronic data (chrominance and luminance) which condition the projection.
