Abstract
Se proporciona un método de decodificación de una corriente de bits de video codificada; el método incluye analizar un indicador; analizar una primera estructura de lista de imágenes de referencia; determinar que un índice para una segunda estructura de lista de imágenes de referencia no está presente en una cabecera de segmento de la corriente de bits de video codificada e inferir que el índice para la segunda estructura de lista de imágenes de referencia es el mismo que un índice para la primera estructura de lista de imágenes de referencia cuando el indicador tiene un primer valor; determinar que el índice para la segunda estructura de lista de imágenes de referencia está presente en la cabecera de segmento cuando el indicador tiene un segundo valor; generar una lista de imágenes de referencia utilizando la primera estructura de lista de imágenes de referencia o la segunda estructura de lista de imágenes de referencia; y ejecutar inter-predicción basada en la lista de imágenes de referencia para generar un bloque reconstruido.
