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.

Abstract: For transmitting a panorama video having a resolution higher than a decoder can decode, at a transmitter side, encoded data coding different (groups of) spatial segments of a video picture of a video stream are packetized into separate substreams, to obtain a group of separate substreams. At a receiver side, from the group of separate substreams a proper subset of the separate substreams is extracted and combined to a data stream containing encoded data coding respectively a proper subset of the spatial segments or groups of subsequent spatial segments of the video picture of the video stream. Thus, a decoder may decode only a subregion of the video picture of the video stream, the subregion being defined by the spatial segments or groups of spatial segments coded in the encoded data contained in the data stream.
