Abstract

SE DESCRIBE UN APARATO PARA REDUCIR SEÑALES PARASITAS EN DIAGONAL DENTADAS, INDESEADAS, EN UNA SEÑAL DE VIDEO. EN UN CODIFICADOR, UN APARATO (38) PROMEDIA INTRACUADROS INFORMACION DE IMAGEN EN MOVIMIENTO EN UNA MARGEN DE FRECUENCIA DADO, POR EJEMPLO, SUPERIOR A 1,5 MHZ, MIENTRAS QUE LA INFORMACION DE IMAGEN FIJA ES SOMETIDA A UN PROCEDIMIENTO DE REPETICION DE CAMPOS EN UN MARGEN DE FRECUENCIAS DADO. EN UN DESCODIFICADOR, UN APARATO (1337) SOMETE A LA INFORMACION DE IMAGEN FIJA A UN PROCEDIMIENTO DE REPETICION DE CUADROS EN EL MARGEN DADO DE FRECUENCIAS DE REPETICION DE CAMPOS, MIENTRAS SE DEJA SIN CAMBIOS LA INFORMACION DE IMAGEN EN MOVIMIENTO.
