Abstract

Se retarda una señal de sincronización vertical en una cantidad seleccionable para producir una señal de sincronización vertical. La señal retardada provoca el comienzo de una porción de trazo de una corriente de deflexión vertical que se va a retrasar con respecto a una señal de video. El tiempo de comienzo retrasado provee un aspecto de paneo superior. Se obtiene información de sincronización para la corriente de deflexión vertical, a partir de la señal de sincronización retardada, sobre una base de campo por campo. La señal de video contiene un campo que provee información de la imagen actualmente presentada en una pantalla de un cinescopio. Se deriva la información de sincronización a partir de un pulso de sincronización vertical de la señal de sincronización vertical no retardada, que ocurre inmediatamente antes del campo y que está asociada con el campo.
