Abstract

Un método de decodificación de video llevado a cabo por un aparato de decodificación de video, de acuerdo con el presente documento, comprende los pasos de: analizar, a partir de un flujo de bits, indicadores asociados con predicción ponderada; analizar una sintaxis de tabla ponderada de predicción a partir de un encabezado de imagen del flujo de bits sobre la base de los indicadores; generar muestras de predicción con respecto a un bloque actual en una imagen actual sobre la base de elementos de sintaxis en la sintaxis de tabla ponderada de predicción; y generar muestras reconstruidas sobre la base de las muestras de predicción, en donde los indicadores comprenden un primer indicador asociado con si la predicción ponderada se aplica a segmentos que se refieren a un conjunto de parámetros de imagen del flujo de bits, y un segundo indicador asociado con si información relacionada con la predicción ponderada está presente en el encabezado de imagen, y el segundo indicador puede analizarse a partir del conjunto de parámetros de la imagen sobre la base del primer indicador.
