Abstract

UN SECCIONADOR DE SEÑAL DE UN SEPARADOR DE SINCRONIZACION INCLUYE UN COMPARADOR (29) PARA GENERAR UNA SEÑAL DE SALIDA DE ACUERDO CON UNA DIFERENCIA ENTRE UNA SEÑAL DE VIDEO RESTAURADA DE NIVEL DEL NEGRO (VIPC) Y UN NIVEL (VSLICE). EL NIVEL DE SECCION SE ESTABLECE DINAMICAMENTE, DE ACUERDO CON EL NIVEL PICO (VIPC) DE LA SEÑAL DE SINCRONIZACION Y EL NIVEL DE NEGRO. CUANDO TIENE LUGAR LA SEÑAL DE SINCRONIZACION EN LA SEÑAL DE VIDEO, LA SEÑAL DE SALIDA DEL SECCIONADOR DE SEÑAL ASUME UN ESTADO LOGICO ACTIVO PRIMERO (PRIMERO); INVERSAMENTE, ENTRE SEÑALES DE SINCRONIZACION QUE TIENE LUGAR CONSECUTIVAMENTE, LA SEÑAL DE SALIDA ASUME UN ESTADO LOGICO INACTIVO SEGUNDO (SEGUNDO). EL NIVEL DE SECCION SE FIJA A UN NIVEL PREDETERMINADO (9/7VBE) PARA IMPEDIR LA EXISTENCIA DE UN ESTADO LOGICO PRIMERO CUANDO NO SE RECIBE SEÑAL DE VIDEO.
