Abstract

La presente solicitud se refiere al procesamiento de ponderación mejorado de intra-interpredicción combinadas. Un método para procesar video incluye: determinar, durante una conversión entre un bloque de video actual, que se codifica en un modo de intra e interpredicción combinadas (CIIP), de un video y una representación de flujo de bits del bloque de video actual, un par de pesos que comprende un primer peso para un primer resultado de predicción del bloque de video actual y un segundo peso para un segundo resultado de predicción del bloque de video actual, con base en uno o más bloques de video colindantes al bloque de video actual, en donde el primer resultado de predicción se genera por medio de un modo de intrapredicción y el segundo resultado de predicción se genera por medio de un modo de interpredicción; y determinar un resultado de predicción del bloque actual con base en una suma ponderada del primer resultado de predicción y el segundo resultado de predicción.
