Abstract

EN EL PROCESO DE FRANJAS DE COLORES CONOCIDO PARA EVITAR LA GRABACION DE LAS SEÑALES DE VIDEO, LA RAFAGA DE COLORES PRESENTE EN CADA LINEA DE VIDEO ACTIVO SE MODIFICA, DE FORMA QUE CUALQUIER CINTA DE VIDEO SIGUIENTE, QUE GRABE LA SEÑAL DE VIDEO, MUESTRE UNAS VARIACIONES EN LA FIDELIDAD DEL COLOR, QUE APARECEN COMO BANDAS NO DESEADAS, O COMO FRANJAS DE ERROR DEL COLOR. ESTE PROCESO DE FRANJAS DE COLOR SE EVITA, PRIMERO, DETERMINANDO LA POSICION DE LAS LINEAS DE VIDEO QUE INCLUYEN EL PROCESO DE LAS FRANJAS DE COLOR, O MEDIANTE LA EXPERIMENTACION PREVIA, O MEDIANTE LA DETECCION EN LINEA. ENTONCES, ALGUNAS O TODAS LAS LINEAS QUE INCLUYEN LAS RAFAGAS DE COLOR MODIFICADAS, SE MODIFICAN PARA PRODUCIR LA SEÑAL DE VIDEO GLOBAL GRABABLE. LA MODIFICACION SE REALIZA DE UN NUMERO DE FORMAS, INCLUYENDO EL DESPLAZAMIENTO DE LA FASE DE LA RAFAGA DE LA FRANJA DE COLOR HASTA LA FASE CORRECTA, REEMPLAZANDO ALGUNAS DE LAS RAFAGAS DE LAS FRANJAS DE COLORES O UNA PORCION DE UNA RAFAGA DE UNA FRANJA DE COLOR PARTICULAR, DE FORMA QUE NO SEAN EFECTIVAS MAS TIEMPO, Y MEZCLANDO LA RAFAGA DE LA FRANJA DE COLOR CON LAS SEÑALES DE LAS FRANJAS DE COLOR CON LA FASE CORRECTA PARA, DE ESTA FORMA, ELIMINAR LA MAYORIA DE, O TODOS, LOS ERRORES DE FASE PRESENTES. LAS RAFAGAS DE COLOR MODIFICADAS SE EVITAN, EN OTRAS VERSIONES, MODIFICANDO LAS SEÑALES DE LOS PULSOS SINCRONOS HORIZONTALES QUE PRECEDEN INMEDIATAMENTE A LAS RAFAGAS DE COLOR MODIFICADAS, DE FORMA QUE LA RAFAGAS DE COLOR MODIFICADAS NO SEAN DETECTADAS POR UN VCR Y, POR TANTO, NO TENGAN NINGUN EFECTO.
