Abstract

Se proporciona un método y aparato de predicción de imágenes de video para proporcionar una manera de determinar una longitud máxima de una lista de vectores de movimiento candidatos correspondientes a un modo de fusión de subbloques. El método comprende analizar un primer indicador desde un flujo de bits; cuando el primer indicador indica que un modo candidato utilizado para interpredecir el bloque que se va a procesar comprende un modo afín, analizar un segundo indicador desde el flujo de bits, donde el segundo indicador se utiliza para indicar una longitud máxima de una primera lista de vectores de movimiento candidatos, y la primera lista de vectores de movimiento candidatos es una lista de vectores de movimiento candidatos construida para el bloque que se va a procesar, se utiliza un modo de predicción de fusión de subbloques para el bloque que se va a procesar; y determinar la longitud máxima de la primera lista de vectores de movimiento candidatos basándose en el segundo indicador.
