Abstract

Un aparato electrónico realiza un método de decodificación de datos de video. El método comprende: recibir datos que codifican un nodo de codificación en árbol; si el nodo de codificación en árbol está codificado en un primer formato de crominancia, establecer el nodo de codificación en árbol en un primer tipo de modo; si el nodo de codificación en árbol está codificado en un segundo formato de crominancia y el nodo de codificación en árbol es una unidad de intra-predicción de crominancia más pequeña. Establecer el nodo de codificación en árbol en un segundo tipo de modo si un bloque de luminancia del nodo de codificación en árbol y el método de división cumplen con un primer criterio; y establecer el nodo de codificación en árbol en un tercer tipo de modo si el bloque de luminancia del nodo de codificación en árbol y el método de división cumplen con un segundo criterio. Decodificar la unidad de codificación en árbol con base en el tipo de modo establecido asociado con el nodo de codificación en árbol.
