Abstract

A picture (1) with multiple slices (2-5) is encoded by determining a hierarchical granularity for the picture (1) defining a hierarchical level for slice border alignments. Address information allowing identification for a respective slice start is determined for at least a portion of the slices (2-5) based on the hierarchical granularity. The pixel values of the slices are encoded to generate coded slice representations (56). These coded slice representations (56) are included together with the address information into a coded picture representation (50) to which information of the hierarchical granularity is associated. The hierarchical granularity provides a flexible way of defining at which coding unit level slice borders can be present in the picture (1).
