Abstract

Un método de decodificación de imágenes llevado a cabo por un dispositivo de decodificación, de acuerdo con el presente documento, comprende los pasos de: adquirir un indicador de ocultación de datos de signo habilitada; adquirir un indicador de codificación residual de salto de transformación (TSRC) habilitada sobre la base del indicador de ocultación de datos de signo habilitada; adquirir información residual para un bloque actual, sobre la base del indicador de TSRC habilitada; derivar una muestra residual del bloque actual, sobre la base de la información residual; y generar una imagen reconstruida sobre la base de la muestra residual, en donde el indicador de ocultación de datos de signo habilitada es un indicador que indica si está habilitado el ocultamiento de datos de signo, el indicador de TSRC habilitada es un indicador que indica si TSRC está habilitada, y el indicador de TSRC habilitada es adquirido sobre la base de que el indicador de ocultación de datos de signo habilitada tenga un valor de cero.
