Abstract
Un método de decodificación de video de JVET que incluye recibir un flujo de bits que indica cómo se dividió una unidad de árbol de codificación en unidades de codificación, y analizar dicho flujo de bits para generar al menos un predictor basándose en un modo de intra predicción señalizada en el flujo de bits, el modo de intra predicción seleccionado de una pluralidad de los modos de intra predicción para el cálculo de un pixel de predicción P(x,y) en la coordinada x,y para la unidad de codificación. Un número de los modos de intra predicción disponibles para la codificación de la unidad de codificación se reducen reemplazando dos o más modos de intra predicción no ponderados mediante un modo de intra predicción ponderado.
