Abstract

EL INVENTO SE REFIERE A UN SISTEMA PARA TRANSMITIR PROGRAMAS ALMACENADOS, TALES COMO PELICULAS Y TEMAS MUSICALES, A LOS CLIENTES POR MEDIO DE UNA RED DE DISTRIBUCION (112, 115, 114, 116), TAL COMO UN SISTEMA DE TELEVISION POR CABLE. LOS PROGRAMAS SE ALMACENAN COMPRIMIDOS EN UNA BIBLIOTECA DE PROGRAMAS (102), TAL COMO UNA LIBRERIA DE CARTUCHOS DE CINTA. AL RECIBIR LA PETICION (EN 103) PARA UN PROGRAMA, UN PROCESADOR DE PETICION (101) ENVIA MENSAJES DE CONTROL QUE PRODUCEN UN BLOQUE DE DATOS QUE COMPRENDE EL PROGRAMA PEDIDO A LEER DE LA BIBLIOTECA DE PROGRAMAS (102) A ALTA VELOCIDAD Y A ALMACENAR EN UNA GRAN MEMORIA DE ACCESO ALEATORIO DINAMICA (DRAM) (111) EN UNA ZONA DE SERVICIO (100). LA ZONA DE SERVICIO, ENVIA ENTONCES EL PROGRAMA DESDE LA DRAM, POR EL SISTEMA DE DISTRIBUCION (112, 115, 114, 116) A UN CLIENTE, COMO UNA SERIE DE PAQUETES DIGITALES. CADA CASO DE ENVIO DE UN PROGRAMA ESTA DIRIGIDO POR UNA PALABRA DE COMANDO SEPARADA. EL CLIENTE PUEDE REALIZAR OPERACIONES TALES COMO LAS DE "AVANCE RAPIDO" ENVIANDO MENSAJES DE CONTROL QUE CAMBIAN LOS INDICADORES DE LA PALABRA DE COMANDO. LAS PALABRAS COMANDO SE PUEDEN AGRUPAR PARA ENVIAR SIMULTANEAMENTE RECUBRIMIENTOS DE VIDEO Y/O AUDIO Y SE PUEDEN LIGAR PARA ENVIAR SERIES DE PROGRAMAS. EL PROCESADOR DE PETICION (101), ZONA DE SERVICIO (100), BIBLIOTECA DE PROGRAMAS (102) E INTERFACES DE LAS REDES DE DISTRIBUCION PUEDEN ESTAR EN DIFERENTES SITUACIONES.
