Abstract

La presente invención describe un método para codificar/decodificar una señal de video y un aparato para el método. De manera más específica, un método para decodificar una señal de video comprende generar un bloque residual de un bloque actual al realizar una decodificación de entropía en la señal de video; si el tamaño del bloque actual es menor que un primer tamaño predeterminado, analizar un indicador de salto de transformación que indica si un salto de transformación se aplica al bloque actual; determinar si se debe analizar un indicador de transformación primaria que indica si una transformación primaria se aplica al bloque actual; si se determina analizar el indicador de transformación primaria, analizar el indicador de transformación primaria; y si el indicador de transformación primaria indica que se aplica una transformación primaria al bloque actual, generar un bloque de transformación de transformación inversa primaria del bloque actual al realizar una transformación inversa primaria al bloque residual.
