Abstract

UN VIDEO DE DEMANDA PERMITE POR EJEMPLO, QUE UNA SEÑAL O PELICULA CODIFICADA SEA TRANSMITIDA A UN ABONADO POR UNA LINEA TELEFONICA METALICA DE DOBLE HILO ESTANDAR. UN APARATO SIMILAR CONECTA DATOS DE SALIDA MOVILES UNIDIRECCIONALES HACIA UN DESTINO VIA LINEA TELEFONICA METALICA ESTANDAR, COMPRENDIENDO EL APARATO UNA GRAN UNIDAD TRANSMISORA DE ENLACE DE ABONADO DE BANDA ANCHA CONECTADA ENTRE LA FUENTE DE DATOS Y UN PUNTO DE CONEXION EN LA LINEA TELEFONICA, Y UNA GRAN UNIDAD RECEPTORA DE ENLACE DE ABONADO DE BANDA ANCHA CONECTADA A OTRO PUNTO DE CONEXION DE LA LINEA TELEFONICA, LO CUAL POSIBILITARIA LA ENTRADA DE UNA SEÑAL PROCEDENTE DE UNA CAMARA DE VIDEO O UN TERMINAL DE ABONADO, Y LA TRANSMISION POR LA LINEA TELEFONICA.
