Abstract

Un circuito que es fácilmente configurado para convertir de una imagen de barrido progresiva, es decir, a una resolucion de 1280 x 720, a una imagen de barrido entrelazada, es decir, a una resolucion entrelazada de 1920 x 1080 (1920 x 540 por campo), o viceversa. Un arreglo del circuito emplea multiplexores de manera a que los dos modos de conversiones compartan el hardware disponible. EL circuito es solo marginalmente más complejo que un circuito que solamente haga la conversion en un sentido. La calidad de la conversion progresiva-a-entrelazados y la calidad de la conversion entrelazada-a-progresiva es al menos suficientemente alta para sistemas de displays progresivos de "medio rango".
