Abstract
La presente descripción se refiere a un método para derivar candidatos de fusión afines construidos; el método incluye adquirir, de un decodificador, un indicador de fusión regular para una unidad de codificación (CU) que está codificada como modo de fusión y modos relacionados con la fusión, cuando el indicador de fusión regular es uno, lo que indica que el modo de fusión regular o el modo de fusión con las diferencias del vector de movimiento (MMVD) se usa por la CU, construyendo una lista de fusión de vectores de movimiento para la CU y usando un índice de fusión regular para indicar qué candidato se usa, y cuando el indicador de fusión regular es cero, lo que indica que la CU no usa el modo de fusión regular, y se utilizan más indicadores de modo de recepción para indicar los modos relacionados con la fusión asociados cuando se cumplen las restricciones de un indicador de modo.
