Abstract

Una modalidad de la presente invención establece una técnica para mitigar la desviación en activos audiovisuales; la técnica incluye determinar que una edición asociada con una línea de tiempo de presentación está dentro de los límites de una trama de video; la técnica además incluye calcular una desviación temporal asociada con la edición, donde la desviación temporal comprende una duración de tiempo entre la edición y un límite de la trama de video; la técnica además incluye determinar si se incluye la trama de video en la línea de tiempo de presentación con base en la desviación temporal y una desviación temporal acumulada asociada con la línea de tiempo de presentación.
