Abstract

UN DECODIFICADOR DE INFORMACION DE VIDEO AUXILIAR PARA DECODIFICAR INFORMACION TAL COMO DATOS DE CAPTURA CERRADOS EN UNA SEÑAL DE VIDEO, IDENTIFICA UNA LINEA HORIZONTAL DESEADA DE VIDEO EN UNA SEÑAL DE VIDEO. SE DETECTA UN IMPULSO DE REFERENCIA EN UNA SEÑAL DE SINCRONIZACION, SEGUIDA DE LA GENERACION DE SEÑALES DE IMPULSOS DE VENTANA PRIMERA Y SEGUNDA, QUE SE PRODUCEN EN RETARDOS PREDETERMINADOS, DESPUES DE LA DETECCION DEL IMPULSO DE REFERENCIA. UN IMPULSO QUE SE PRODUZCA EN LA SEÑAL DE SINCRONIZACION DURANTE LOS IMPULSOS DE VENTANA INDICA EL COMIENZO DEL INTERVALO DE LINEA HORIZONTAL DESEADO. PUEDE GENERARSE TAMBIEN UNA SEÑAL DE IDENTIFICACION DE CAMPO. SE FACILITAN CARACTERISTICAS PARA PERFECCIONAR LA INMUNIDAD DE ERRORES DE FASE Y RUIDO CUANDO SE IDENTIFICA UNA LINEA DE VIDEO.
