Abstract

Decodificador para decodificar una imagen a partir de un flujo de datos, configurado para verificar (106) si una pluralidad (98) de parámetros de codificación, que están contenidos en el flujo de datos (14), se relacionan con una porción predeterminada (100) de la imagen (12 ) y controlar un modo de transformada residual de predicción y una precisión de cuantificación con respecto a la porción predeterminada, son indicativos de una configuración de parámetros de codificación que corresponde a una codificación residual de predicción sin pérdidas. En respuesta a la pluralidad de parámetros de codificación que son indicativos de la configuración de parámetros de codificación que corresponde a la codificación residual de predicción sin pérdidas, el decodificador está configurado para configurar una o más opciones de codificación predeterminadas relacionadas con una o más herramientas del decodificador para procesar una reconstrucción predictiva corregida residual de predicción con respecto a la porción predeterminada de modo que la una o más herramientas estén inhabilitadas con respecto a la porción predeterminada.
