Abstract

Una disposicion para la distribucion de informacion digitalizada de imágenes y de audio a localizaciones de proyeccion, particularmente de material deprogramacion visual o de audio de muy alta calidad desde uno o más concentradores centrales (102) auna o más localizaciones de presentacion (56, 104), talescomo salas que utilizan enlaces de datos de alta velocidad, tales como satélites (106). En el concentrador central (102), un sistema de generacion deorigen (108) genera una senal de programael ectronico desde una senal analogica, un sistema de compresion/cifrado (110) codifica y cifra de manera digitalla senal electronica, y un sistema de modulacion/transmision (114) procesa la senal para la transmision a través del satélite (106). Unsist ema deadministracion de la red (112) en el concentrador central (102) controla la operacion del concentrador. En la sala (56) o en otra localizacion, un receptor/desmodulador (120) recibe la senal de programacion transmitida con el uso delsatélite ( 106). Un sistema de administracion de la sala (122) controla,entonces, el almacenamiento, la encaminacion, el descifrado y la exhibicion del material de programacion recibido. Los arreglos de almacenamiento (124A-124N)en el sistema de lasala (104A-1 04N) proporcionan el almacenamiento centralizado del material de programacion. el material de programacion se encaminaa través de una red de área local a los auditorios designados, varios de los cuales pueden funcionar dentro de unsistema de la sala (104A-104N). Tambiénse proponen aparatos para que en cada auditorio, el material de programacion se descomprime y se descifra para la exhibicion con el uso de equipos deproyeccion electronicos (132A) y sistemas de sonido deauditorios de tipo estánd ar (134A); y un método para distribuir dicha informacion digitalizada queutiliza dicha disposicion.A provision for the distribution of digitized information of images and audio to projection locations, particularly of very high quality visual or audio programming material from one or more central hubs (102) to one or more presentation locations (56, 104) , such as rooms that use high-speed data links, such as satellites (106). In the central hub (102), an original generation system (108) generates an electronic program signal from an analog signal, a compression / encryption system (110) encodes and encrypts digitally the electronic signal, and a modulation system / transmission (114) processes the signal for transmission via satellite (106). A network administration (112) in the central hub (102) controls the operation of the hub. In the room (56) or in another location, a receiver / demodulator (120) receives the programming signal transmitted with the use of the satellite (106). A room management system (122) then controls the storage, routing, decryption and display of the received programming material. Storage arrangements (124A-124N) in the lasala system (104A-1 04N) provide centralized storage of programming material. The programming material is routed through a local area network to the designated auditoriums, several of which can operate within a room system (104A-104N). Devices are also proposed so that in each auditorium, the programming material is decompressed and deciphered for the exhibition with the use of electronic projection equipment (132A) and standard audio sound systems (134A); and a method for distributing said digitized information that uses said provision.
