Abstract

EN UN SISTEMA DE TRANSMISION DE SEÑAL AUDIO/VIDEO EN PAQUETE LA INFORMACION DE GUIA DE PROGRAMA SE FORMA COMO UNA GUIA MAESTRA (250) Y UNA GUIA ESPECIAL (260) LA GUIA MAESTRA CONTIENEN LA INFORMACION DE PROGRAMACION PARA EL PERIODO DE LAS DIVERSAS HORAS ACTUALES. LA GUIA ESPECIAL CONTIENEN LA INFORMACION DE PROGRAMACION PARA LOS SIGUIENTES TREINTA DIAS, POR EJEMPLO. LA GUIA MAESTRA SE ENVIA COMO UN SERVICIO SOBRE CADA PORTADORA O TRANSPORTADORA (210-230, 240) PARA HACERLO MAS DISPONIBLE SIN IMPORTAR LA FRECUENCIA PORTADORA A LA QUE EL RECEPTOR ESTA SINTONIZADA. LA GUIA ESPECIAL (260) SE TRANSMITE SOBRE SOLO UNA DE LAS PORTADORAS (TRANSPORTADORTAS) PARA MINIMIZAR EL USO DE LA BANDA ANCHA DEL SISTEMA.
