Abstract
La presente invención proporciona un método de codificación, en donde el método comprende: determinar los elementos de sintaxis que han de codificarse, en donde los elementos de sintaxis incluyen una estructura de lista de imágenes de referencia y al menos un parámetro de predicción ponderada de sintaxis de alto nivel (HLS); codificar al menos un parámetro de predicción ponderada de HLS; y codificar la estructura de lista de imágenes de referencia siguiendo la codificación de al menos un parámetro de predicción ponderada de HLS. Los elementos de sintaxis se reordenan de manera que la codificación de la estructura de lista de imágenes de referencia puede basarse en los valores de al menos un parámetro de predicción ponderada de HLS.
