Abstract

Se proporcionan dispositivos y métodos para la intrapredicción. El método incluye: obtener un valor de una información de indicación de un bloque actual. Cuando el valor de la información de indicación indica que el modo de intrapredicción del bloque actual no está incluido en el conjunto de modos más probables, derivar el modo de intrapredicción IntraPredModeY[xCb][yCb] del bloque actual mediante los siguientes pasos ordenados: i. IntraPredModeY[xCb][yCb] se establece igual a intra_luma_mpm_remainder[xCb][yCb], ii. El valor de IntraPredModeY[xCb][yCb] se incrementa en uno. El método puede mejorar la eficiencia para determinar el modo de intrapredicción del bloque actual.
