Abstract

CON LA NUEVA GENERACION DE SISTEMAS DE TV DE PAGO QUE UTILIZAN UN SISTEMA DE ACCESO DE CONTROL BASADO EN EL PROCESAMIENTO DE UNA TARJETA LIGERA (25), EL DECODIFICADOR DE LA TV DE PAGO (26) HA PERDIDO SU IDENTIDAD. ESTO SIGNIFICA QUE TODOS LOS DATOS SON DIRECCIONADOS A UNA DIRECCION DADA QUE PERTENECE A LA TARJETA LIGERA Y NO AL DECODIFICADOR. ESTOS SISTEMAS OFRECEN UN ACCESO DE CONTROL MOVIL PERO PIERDEN LA INFORMACION GEOGRAFICA. ESTA INVENCION PROPORCIONA UNA SOLUCION FLEXIBLE PARA PODER LLEVAR DATOS PARA UN ACCESO DE CONTROL BASADO TANTO EN UNA TARJETA LIGERA COMO EN UN DECODIFICADOR, PARA LOS SISTEMAS DE TV DE PAGO EN PAL, SECAM Y NTSC. LA INFORMACION, TAL Y COMO SE LISTA MAS ABAJO, SE CARGA A TRAVES DEL CANAL DE TRANSMISION: TABLA DE ASIGNACION DEL CANAL ESPECIFICO; VTR DEL CLIENTE; EOGRAFICA. PARA LLEVAR LOS DATOS, LA INVENCION UTILIZA DOS GRUPOS DE N LINEAS DE VIDEO QUE REPRESENTAN A DOS CANALES DE DATOS. CADA UNO DE LOS PAQUETES DE DATOS DE ESTE CANAL CONTIENEN DOS TIPOS DE INFORMACION: DATOS DESCRIPTORES Y DATOS DE APLICACION. EN UN RECEPTOR, LOS DATOS SE EXTRAEN DE LAS LINEAS DE VIDEO MEDIANTE UN DESPACHADOR DE DATOS (22). TRAS RECIBIR UN PAQUETE DE UN CANAL DE DATOS, EL DESPACHADOR DE DATOS ANALIZA LOS DATOS DESCRIPTORES QUE CONTIENEN INFORMACION QUE DESCRIBE AL BLANCO. EL DESPACHADOR DE DATOS TRANSMITE LOS DATOS DE APLICACION QUE SE ENCUENTRAN EN EL PAQUETE A LA UNIDAD PROCESADORA CORRECTA, SIN ANALIZARLOS: BIEN A UN PROCESADOR DEL ACCESO DE CONTROL (23) O A UN PROCESADOR INTELIGENTE DECODIFICADOR (26).
