1. A non-transitory digital storage medium storing a video data stream comprising:
a sequence of slice portions, each slice portion having encoded thereinto a respective slice of a plurality of slices of a picture of a video, wherein each slice portion comprises a slice address indicating a location where, in a picture area of the video, the slice is located which the respective slice portion has encoded thereinto; and
extraction information for usage in an extraction of a reduced video data stream from the video data stream, the reduced video data stream having encoded thereinto a spatially smaller video corresponding to a spatial section of the video of the video data stream, the extraction involving confining the video data stream to slice portions having encoded thereinto any slice within the spatial section and amending the slice address so as to relate to a decreased picture area of the spatially smaller video, the extraction information comprising:
first information defining the spatial section within the picture area; and
second information explicitly signalling substitute slice addresses for a replacement of the slice addresses of the slice portions of the slices within the spatial section, the substitute slice addresses indicating, within the reduced video data stream, the location where, in the decreased picture area, the slices are located,
wherein the sequence of slice portions comprises: slice portions having encoded thereinto a slice within the spatial section and slice portions having encoded thereinto a slice external to the spatial section.
