Abstract

Los presentes principios se refieren a un método para codificación de una unidad de imagen comprendiendo datos de imagen representados por un canal de luminancia y al menos un canal de crominancia, el método comprendiendo obtener un árbol de codificación luma separando una unidad de luminancia representativa del canal de luminancia de dicha unidad de imagen y obtener un árbol de codificación croma separando una unidad de crominancia representativa de al menos un canal de crominancia de dicha unidad de imagen. El método está caracterizado en que obtener dicho árbol de codificación croma comprende: -determinar si dicho árbol de codificación croma y dicho árbol de codificación luma son idénticos; y -señalizar datos de información indicando si dicho árbol de codificación croma y dicho árbol de codificación luma son idénticos.
