Abstract

UN SISTEMA PROCESADOR DE TRANSPORTE INVERSO PARA UN RECEPTOR DE TV DE SEÑALES DE PAQUETES DE TDM QUE INCLUYE UN APARATO PARA EXTRAER SELECTIVAMENTE LAS CARGAS DE PAGO DESEADAS DE LOS DATOS DE LOS COMPONENTES DE PROGRAMAS Y ACOPLAR ESTOS DATOS A UN PUERTO DE ENTRADA DE DATOS EN UNA MEMORIA INTERMEDIA. UN MICROPROCESADOR (19) ASOCIADO AL SISTEMA ACOPLA TAMBIEN LOS DATOS AL PUERTO DE ENTRADA DE DATOS A LA MEMORIA INTERMEDIA (18). LAS CARGAS DE PAGO DE LOS COMPONENTES RESPECTIVOS Y LOS DATOS GENERADOS POR EL MICROPROCESADOR QUEDAN ALMACENADOS EN UNOS BLOQUES RESPECTIVOS DE LA MEMORIA INTERMEDIA COMUN EN RESPUESTA A LAS DIRECCIONES DE MEMORIA QUE UN MULTIPLEXOR DE DIRECCIONES (17) APLICA A UN PUERTO DE ENTRADA DE DIRECCIONES DE MEMORIA. HAY UN DISPOSITIVO DE DESCIFRADO (16) PARA QUE DESCIFRE LOS DATOS SOBRE LAS CARGAS DE PAGO SEGUN UNAS CLAVES DE DESCIFRADO ESPECIFICAS DE PAQUETES. ADEMAS HAY UN DETECTOR (15) PARA QUE DETECTE LAS CARGAS DE PAGO QUE INCLUYEN DATOS DE TITULARIDAD. LAS CARGAS DE PAGO QUE CONTIENEN LOS DATOS DE TITULARIDAD SON DIRIGIDAS A TRAVES DE LA MEMORIA INTERMEDIA COMUN A UNA TARJETA CON MICROPROCESADOR QUE GENERA LAS CLAVES DE DESCIFRADO ESPECIFICAS DE LOS PAQUETES. HAY UN PUERTO DE SALIDA DE DATOS DE LA MEMORIA ACOPLADO A UN BUS QUE HAY INTERCONECTADO A LOS PROCESADORES DE LOS COMPONENTES DE PROGRAMAS RESPECTIVOS (21-24). SE ARBITRAN LA SENSIBILIDAD DE RESPUESTA LAS PETICIONES DE DATOS DE LOS PROCESADORES DE LOS COMPONENTES DE PROGRAMAS RESPECTIVOS Y LAS PETICIONES DE ESCRITURA DE DATOS DE LA FUENTE DE CARGA DE PAGO DE LOS COMPONENTES, EL ACCESO A MEMORIA PARA REALIZAR FUNCIONES DE LECTURA Y ESCRITURA (17) PARA QUE ASI NO SE PIERDA NINGUN DATO ENTRANTE SOBRE LOS PROGRAMAS Y SE PRESTE SERVICIO A TODOS LOS PROCESADORES DE COMPONENTES.
