1. A stream multiplexer, comprising:
a reception interface for receiving encoded data for each of at least two different spatial segments or different groups of subsequent spatial segments of a video picture of a video stream encoded thereinto; and
a data stream former configured to packetize the encoded data for each of the at least two different spatial segments or different groups of subsequent spatial segments into separate substreams, and to provide the separate substreams at an output,
wherein the at least two different spatial segments or different groups of subsequent spatial segments of the video picture of the video stream are encoded such that the encoded data comprises, for each video picture, at least one slice;
wherein the data stream former is configured to packetize the slice or slices for each spatial segment or group of spatial segments into one separate substream;
wherein the data stream former is configured to, for the slices of at least one of the spatial segments or groups of subsequent spatial segments,
packetize the slices of the at least one of the spatial segments or groups of subsequent spatial segments into the separate substream; and
provide a further separate stream comprising suitable slice headers, which are, relative to the slices of the at least one of the spatial segments or groups of subsequent spatial segments, modified with respect to its picture position or picture size.
