Abstract

UNA SEÑAL DE TELEVISION DE ALTA DEFINICION TRANSMITIDA SE REPRESENTA POR UN FLUJO DE DATOS PAQUETIZADOS CONFIGURADOS COMO UNA SECUENCIA DE CAMPOS DE DATOS (FIG,1) CON UNA PROPORCION DE DATOS NO UNIFORME PARA INTERVALOS DE INFORMACION DE CABECERA ENTRE DATOS NO IGUALES. CADA CAMPO DE DATOS ES FABRICADO POR UN SEGMENTO DE CABECERA DE CAMPO SYNC SEGUIDO POR SEGMENTOS DE DATOS PAQUETIZADOS 312 CADA UNO CON INFORMACION DE SOBRECABECERA ASOCIADA (FEC). UN TRANSMISOR (FIG.33), UN PROCESADOR DE TRANSPORTE (14) FORMA PAQUETES DE DATOS CON CABECERAS ASOCIADAS Y ADMINISTRA OPERACION SIN INTERRUPCION A UNA PROPORCION DE DATOS UNIFORME CONSTANTE, MIENTRAS QUE SUMINISTRA UN FLUJO DE DATOS PAQUETIZADOS A UNA RED (17) QUE CONSTRUYE CAMPOS DE DATOS SECUENCIALES POR INSERTAR INFORMACION DE SOBRECABECERA DE NO DATOS DENTRO DEL FLUJO DE DATOS. EL PROCESADO DE TRANSPORTE ES VENTAJOSAMENTE OPERADO A UNA RELACION DE DATOS UNIFORME CONSTANTE SIN TENER QUE MODIFICAR LA ESTRUCTURA DE CAMPOS DE DATOS ORIGINALES PARAACOMODARSE A LAS NECESIDADES DE LA RED DE CONSTRUCCION DEL CAMPO DE DATOS. ESTE RESULTADO ES FACILITADO POR TRANSFERIR DATOS DEL PROCESADOR DE TRANSPORTE A UNA RED DE MEMORIA/ INTERFAZ (46) ASOCIADO EN RESPUESTA A UN RELOJ DE SIMBOLO 3/8, EN COMBINACION CON UN NIVEL ABUNDANTE DE MEMORIA PREDETERMINADA. ESPECIFICAMENTE, UN DISPOSITIVO GRABADOR/REPRODUCTOR DE VIDEO (15) RECIBE UN FLUJO DE DATOS PAQUETIZADOS DE PROPORCION DE DATOS UNIFORME CONSTANTE DESDE EL PROCESADOR DE TRANSPORTE,Y SACA UN FLUJO DE DATOS DE PROPORCION DE DATOS UNIFORME CONSTANTE A LA RED DE INTERFAZ/MEMORIA. UN PROCESADOR (DECODIFICADOR DE TRANSPORTE DUPLICADO (86)) A UN RECEPTOR (FIG.34) COACCIONA CON UN PROCESADOR DE CAMPO DE DATOS (75) Y ADMINISTRA SIMILARMENTE OPERACION SIN INTERRUPCION A UNA PROPORCION DE DATOS UNIFORME CONSTANTE. UN DISPOSITIVO GRABADOR/REPRODUCTOR (85) RECIBE UN FLUJO DE DATOS DE PROPORCION DE DATOS UNIFORME CONSTANTE DESDE UN INTERFAZ/MEMORIA (84) QUE DESPUES REMUEVE LA INFORMACION DE CABECERA, Y SACA UN FLUJO DE DATOS DE PROPORCION DE DATOS UNIFORME AL DECODIFICADOR DE TRANSPORTE.
