Abstract
Un método de decodificación de datos de video incluye derivar, para un bloque actual de datos de video y usando derivación de intra-modo de lado de decodificador (DIMD), una lista de intra-modos usando muestras reconstruidas de bloques vecinos; construir, para el bloque actual, una lista de modo más probable (MPM), en donde construir la lista de MPM comprende insertar, en la lista de MPM, al menos un intra-modo de la lista derivada de intra-modos; y predecir, usando un candidato seleccionado de la lista de MPM construida, el bloque actual.
