1. A method for providing digital video data, the method comprising:

  • selecting plural representations of a video signal, wherein each of the plural representations includes a respective sequence of pictures, wherein each picture in each of the plural representations originates from a corresponding respective picture of the video signal, wherein the order of successive pictures in each of the selected plural representations of the video signal corresponds to the order of successive pictures in the video signal;

    processing the selected plural representations of the video signal, wherein processing comprises selectively shifting, in time, at least a first, selected plural representation of the video signal relative to a second, selected plural representation of the video signal different from the first, selected plural representation of the video signal, wherein selectively shifting is enabled by auxiliary information identifying a plurality of lattices, wherein the auxiliary information includes information indicating how decoded versions of compressed video frame partitions are to be assembled into a larger frame, wherein the auxiliary information further includes information indicating the relative temporal order of the plurality of lattices and corresponding segments in the video signal;

    processing second auxiliary information different from the previously processed auxiliary information, wherein the second auxiliary information providing spatial relationship information for the decoded versions of compressed video; and

    providing in a video stream a first plurality of the processed pictures of a second representation of the video signal (SROTVS) after providing at least a portion of a first plurality of the processed pictures of a first representation of the video signal (FROTVS).
