Abstract

Un decodificador de video puede recibir, en un flujo de bits que comprende una representación codificada de datos de video, información que indica si un bloque residual está particionado e información que indica un tipo de árbol de partición para el bloque residual basado en el bloque residual que se está particionando, en donde el bloque residual es indicativo de una diferencia entre un bloque actual y un bloque de predicción. El decodificador de vídeo puede determinar, basándose en la información recibida, que el bloque residual está particionado y el tipo de árbol de partición para el bloque residual, una pluralidad de subbloques residuales en los que se particiona el bloque residual de acuerdo con el tipo de árbol de partición. El decodificador de vídeo puede producir los datos residuales para el bloque actual basándose al menos en parte en el bloque residual que se particiona según el tipo de árbol de partición en la pluralidad de subbloques residuales y puede decodificar el bloque actual utilizando los datos residuales.
