Abstract
Un método que incluye: decodificar un flujo de bits y de esta forma emitir coeficientes de transformada para cada componente de color del bloque, un primer indicador indica para cada componente de color si el bloque incluye un coeficiente de transformada de no cero, y un segundo indicador indica si el bloque ha sido codificado usando una transformada de espacio de color que transforma un espacio de color de una predicción residual de un espacio de color de la imagen original en otro espacio de color; realizar una transformada inversa de espacio de color para la predicción residual restaurada a partir de los coeficientes de transformada, cuando el segundo indicador indica que el bloque ha sido codificado usando la transformada de espacio de color; y determinar si realizar o no el escalamiento residual de croma para la predicción residual del componente de crominancia, con base en el primer indicador de un componente de crominancia y el segundo indicador, el escalamiento residual de croma que realiza el escalamiento con base en un componente de luminancia correspondiente al componente de crominancia.
