Abstract

Sub-picture extraction is rendered less complex by providing each slice with start position information which indicates a starting position from which onwards the picture is, along a coding path, encoded into the respective slice, relative to an onset position at which the coding path starts traversing a segment the starting position is located in. Alternatively or additionally, sub-picture extraction processes are treated like choosing one layer out of a multi-layer datastream.
