Abstract
APARATO PARA EL TRATAMIENTO INTRACUADROS, SELECTIVO EN FRECUENCIA, DE UNA SEÑAL DE VIDEO. UNA SEÑAL DE TELEVISION DE PANTALLA ANCHA QUE CONTIENE INFORMACION DE PANEL CENTRAL E INFORMACION DE PANELES LATERALES COMPRIMIDA EN EL TIEMPO EN UNA REGION DE SOBREEXPLORACION ES TRATADA INTRACUADROS POR ENCIMA DE UNA FRECUENCIA DADA SOLAMENTE CON RESPECTO A LA INFORMACION DEL PANEL CENTRAL. EL APARATO (38) DE TRATAMIENTO INTRACUADROS INCLUYE UN CIRCUITO (1120, 1122) DE RETARDO DE SEÑAL CON UN PRIMER Y UN SEGUNDO ELEMENTOS DE RETARDO DE 262 INTERVALOS DE LINEA HORIZONTAL ENTRE UNA ENTRADA Y UNA SALIDA DEL CIRCUITO DE RETARDO. ES GENERADA UNA SEÑAL DE SALIDA TRATADA INTRACUADROS COMBINANDO (1134) LOS TERMINOS DE DIFERENCIA PROCEDENTES DE UNA VIA DE SEÑAL CON UNA SEÑAL PRESENTE EN EL PUNTO DE RETARDO INTERMEDIO. APLICACION EN TELEVISION.
