摘要： A section-specific video data stream is derived by reducing a video data stream pertaining an entire scene with conservation of conformance by use of a file format and incorporating slices into which tiles of a set of tiles are encoded which forms the section, are incorporated into a set of one or more source tracks and a set of one or more gathering tracks including construction instructions is used in order to indicate a synthesis of the section-specific video data stream by signaling replacements of certain portions of the slices and instructing to copy certain portions of the slices. Further, there is described a concept pertaining an indication of a position of a region of interest.

摘要： 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.

摘要： A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and/or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.
