Abstract

Un método de decodificación de imágenes llevado a cabo por un aparato de decodificación de acuerdo con el presente documento comprende los pasos de: obtener un indicador de disponibilidad de ocultación de datos de señal que indique si la ocultación de datos de señal está disponible o no para un segmento actual; obtener un indicador de disponibilidad de TSRC que indique si TSRC está disponible o no para un bloque de salto de transformación del segmento actual; obtener información de codificación residual sobre el bloque de salto de transformación sobre la base del indicador de disponibilidad de TSRC; derivar una muestra residual para el bloque de salto de transformación sobre la base de la información de codificación residual; y generar una imagen de reconstrucción sobre la base de la muestra residual, en donde el indicador de disponibilidad de TSRC se obtiene sobre la base del indicador de disponibilidad de ocultación de datos de señal.
