Abstract

SISTEMA DE TELETEXTO PARA DIFUSION DE DATOS.LOS DATOS SON DIFUNDIDOS POR LA ESTACION EMISORA BAJO FORMA DE PAQUETES, COMPRENDIENDO CADA PAQUETE UN PREFIJO QUE CONTIENE, ADEMAS DE LAS SEÑALES DE SINCRONIZACION CLASICAS DE CODIGO DE IDENTIFICACION DE VIA, UNA SEÑAL DE INDICE DE CONTINUIDAD DE PAQUETE. LOS DATOS DE CADA FICHERO ESTAN ORDENADOS EN GRUPOS DE DATOS FORMADOS POR UNA SERIE DE BLOQUES DE DATOS, COMPRENDIENDO EL PRIMER BLOQUE DE CADA GRUPO UN ENCABEZAMIENTO DE GRUPO FORMADO POR OCTETOS QUE DEFINEN EL TIPO DE GRUPOS, EL INDICE DE CONTINUIDAD DELGRUPO, EL NUMERO DE BLOQUES DEL GRUPO QUE SIGUEN AL PRIMER BLOQUE, Y EL TAMAÑO DEL ULTIMO BLOQUE DEL GRUPO, COMPRENDIENDO ADEMAS EL PREFIJO DE CADA PAQUETE UNA INFORMACION QUE INDICA SI EL BLOQUE DEL PAQUETE ES O NO EL PRIMER BLOQUE DE UN GRUPO. EL SUBCONJUNTO DE TRATAMIENTO COMPRENDE UNA PRIMERA PARTE DE TRATAMIENTO DE LOS PAQUETES, Y UNA SEGUNDA PARTE DE TRATAMIENTO DE LOS GRUPOS.
