Abstract
Se proporciona un método para codificación de video. El método incluye: dividir imágenes de video en una pluralidad de unidades de codificación (CU), al menos una de las cuales está además dividida en dos unidades de predicción (PU) incluyendo al menos una PU de forma triangular con una orientación de división en uno de: de la esquina superior izquierda a esquina inferior derecha, y de la esquina superior derecha a la esquina inferior izquierda; construir una lista de candidato de vector de movimiento de uni-predicción; determinar si una CU actual es codificada como modo de predicción de triángulo de acuerdo con información codificada; señalizar un indicador de orientación de división que indica la orientación de división; y señalizar valores de índice que indican entradas seleccionadas en la lista de candidato de vector de movimiento de uni-predicción construida.
