Abstract
Se divulga un método de decodificación que comprende: - determinar si un bloque actual de una imagen se extiende más allá de un límite de la imagen; - determinar, para cada modo de división de una pluralidad de modos de división, si dicho bloque actual tiene permitido experimentar la división de acuerdo con dicho modo de división verificando si al menos una de la línea de división está co-ubicada con uno del borde de imagen o si el tamaño de la parte de bloque dentro de la imagen a lo largo del límite de imagen es un múltiplo de un tamaño de bloque mínimo; - decodificar, de la corriente de bits, un modo de división actual del bloque actual que responda a los modos de división permitidos; y - decodificar el bloque actual de acuerdo con el modo de división actual.
