Abstract

Un decodificador de video recibe datos a ser decodificados de un flujo de bits para un bloque de pixeles a ser decodificado como un bloque actual de una imagen actual del video. El decodificador de video genera una primera predicción del bloque actual con base en un primer modo de predicción que se selecciona de una primera lista de candidatos. El decodificador de video genera una segunda predicción del bloque actual con base en un segundo modo de predicción que se selecciona de una segunda lista de candidatos. El decodificador de video genera una predicción combinada para el bloque actual con base en la primera predicción y la segunda predicción. El decodificador de video reconstruye el bloque actual usando la predicción combinada.
