Abstract

UN RECEPTOR DE TELEVISION IMAGEN EN UNA IMAGEN INCLUYE UNA MEMORIA PARA MANTENER MUESTRAS QUE REPRESENTAN UNA IMAGEN HORIZONTAL Y VERTICALMENTE COMPRIMIDA. LA MEMORIA SE DIVIDE EN TRES PARTES: UNA PARTE PRINCIPAL QUE MANTIENE UN CAMPO DE LA IMAGEN COMPRIMIDA, Y PRIMERO Y SEGUNDO BUFFER DE CRUCE, CADA UNO DE LOS CUALES TIENE UNA LINEA DE LA SEÑAL COMPRIMIDA. AMBOS TIPOS DE CAMPO SUPERIOR E INFERIOR PUEDEN OBTENERSE DE CADA CAMPO DE LA SEÑAL AUXILIAR UTILIZADA PARA OBTENER LA IMAGEN COMPRIMIDA. VALORES DE MUESTRAS SE ALMACENAN DENTRO DE LA MEMORIA EN TAL FORMA QUE UN CAMPO SUPERIOR DE LA IMAGEN COMPRIMIDA SE ALMACENA CUANDO UN CAMPO SUPERIOR DE LA IMAGEN PRINCIPAL SE PRESENTA, Y UN CAMPO INFERIOR SE ALMACENA CUANDO SE PRESENTA UN CAMPO INFERIOR. CUANDO LA DIRECCION UTILIZADA PARA LEER MUESTRAS DESDE LA MEMORIA ALCANZA LA DIRECCION UTILIZADA PARA ESCRIBIR MUESTRAS DENTRO DE LA MEMORIA, EL TIPO DE CAMPO OBTENIDO DE LA SEÑAL AUXILIAR SE CONMUTA, Y UNA LINEA DE MUESTRAS SE DIRIGE A UNO DE LOS BUFFER DE CRUCE. DURANTE ESTE TIEMPO, LA DIRECCION LEIDA SE CAMBIA A MUESTRAS LEIDAS DESDE EL OTRO DE LOS BUFFER DE CRUCE. ESTE APARATO REDUCE LA DISTORSION EN LA IMAGEN COMPRIMIDA CAUSADA POR LA FALTA DE ALINEAMIENTO DEL CAMPO ENTRE LAS SEÑALES PRINCIPALES Y AUXILIARES.
