Abstract
La codificación y decodificación de video se implementa con autocodificadores usando información de luminancia para derivar información de movimiento para la predicción de crominancia. En una modalidad se usan convoluciones condicionales para codificar la información de flujo de movimiento. Una condición actual, por ejemplo, la estructura GOP, se usa como entrada a una sucesión de capas completamente conectadas para implementar la convolución condicional. En una modalidad relacionada, se usa más de una trama de referencia para codificar la información de flujo de movimiento.
