Abstract

EN UN RECEPTOR DE TELEVISION, QUE EMPLEA TANTO UN SISTEMA DE MODULACION DE LA VELOCIDAD DE EXPLORACION (SUM) DEL HAZ (35) COMO UN GENERADOR (40) DE VISUALIZACION EN PANTALLA (OSD), EL GENERADOR OSD OPERA SELECTIVAMENTE PARA PRODUCIR CARACTERES O GRAFICOS QUE SE SOBREIMPONEN EN LA VISUALIZACION DE LA IMAGEN DE VIDEO PRINCIPAL. DURANTE EL FUNCIONAMIENTO DEL GENERADOR OSD, EL CIRCUITO SUM PUEDE TENDER A INTRODUCIR ARTEFACTOS NO DESEABLES EN LA VISUALIZACION DE LA IMAGEN. SE FACILITA UN CIRCUITO (19) PARA ANULAR SELECTIVAMENTE LA OPERACION NORMAL DEL CIRCUITO SUM DURANTE EL FUNCIONAMIENTO DEL OSD PARA EVITAR O REDUCIR LA PERCEPCION DE DICHOS ARTEFACTOS.
