1. A method comprising decoding a picture, wherein the picture is divided into one or more blocks of samples and wherein a block of samples is further partitioned into at least two block partitions, said decoding further comprising:
receiving in video data quantized transform coefficients;
entropy decoding, de-quantizing and inverse transforming the transform coefficients to obtain a residual of block partitions; and
reconstructing a block of samples based on a prediction of the block partitions and the residual of block partitions,
wherein at least one block partition is obtained using, based on a block of samples being located on a border of the picture, asymmetric binary partitioning as implicit split for the block of samples, wherein asymmetric binary partitioning as implicit split is a sole split mode type allowed for the at least one block partition.
