Abstract
Se proporciona un método para decodificar una corriente de bits de video codificada implementado por un decodificador de video; el método incluye analizar un indicador; analizar candidatos para una primera estructura de lista de imágenes de referencia; determinar que candidatos para una segunda estructura de lista de imágenes de referencia no están presentes en la corriente de bits de video codificada en inferir que los candidatos para la segunda estructura de lista de imágenes de referencia son los mismos que los candidatos para la primera estructura de lista de imágenes de referencia cuando el indicador tiene un primer valor; determinar que los candidatos para la segunda estructura de lista de imágenes de referencia están presentes en la corriente de bits de video codificada cuando el indicador tiene un segundo valor; generar una lista de imágenes de referencia utilizando los candidatos para la primera estructura de lista de imágenes de referencia o los candidatos para la segunda estructura de lista de imágenes de referencia; y ejecutar inter-predicción con base en la lista de imágenes de referencia para generar un bloque reconstruido.
