Abstract
De acuerdo con modalidades del presente documento, una lista de candidatos de modo de predicción intra de un bloque actual se puede construir por medio de un proceso de construir una lista de modos de predicción intra común con respecto a los tipos de predicción intra. Por consiguiente, se reduce la dependencia de los tipos de predicción intra en el proceso de construir la lista de modos de predicción intra y, por lo tanto, se puede mejorar la eficiencia de codificación de la predicción intra.
