Abstract
os presentes princípios se referem a um método para codificar uma unidade de imagem que compreende dados de imagem representados por um canal de luminância e pelo menos um canal de crominância, sendo que o método compreende obter uma árvore de codificação luma dividindo-se uma unidade de luminância representativa do canal de luminância da dita unidade de imagem e obter uma árvore de codificação croma dividindo-se uma unidade de crominância representativa de pelo menos um canal de crominância da dita unidade de imagem. o método é caracterizado pelo fato de que obter a dita árvore de codificação croma compreende determinar se a dita árvore de codificação croma e a dita árvore de codificação luma são idênticas sinalizar um dado de informação que indica se a dita árvore de codificação croma e a dita árvore de codificação luma são idênticas.
