Abstract:
Coding schemes for coding a spatially sampled information signal using sub-division and coding schemes for coding a sub-division or a multitree structure are described, wherein representative embodiments relate to picture and/or video coding applications.

Claim (Index 11):
A method comprising:\n extracting, from a data stream representing video information, information related to first and second maximum region sizes and first and second subdivision information, wherein the first maximum region size and the first subdivision information is associated with prediction coding and the second maximum region size and the second subdivision information is associated with transform coding; dividing an array of information samples representing a spatially sampled portion of the video information into a first set of root regions based on the first maximum region size; sub-dividing at least some of the first set of root regions into a first set of sub-regions using recursive multi-tree partitioning based on the first subdivision information; determining whether a size of at least one of the first set of sub-regions exceeds the second maximum region size; responsive to a determination that the size of at least one of the first set of sub-regions does exceed the second maximum region size, dividing at least one of the first set of sub-regions into a second set of root regions of the second maximum region size; and determining, for each of the second set of root regions of the second maximum region size, whether the respective root region of the second set of root regions is to be sub-divided; responsive to a determination that the respective root region of the second set of root regions is to be sub-divided, sub-dividing the respective root region of the second set of root regions into a second set of sub-regions using recursive multi-tree partitioning based on the second subdivision information; and reconstructing the array of information samples using prediction coding in accordance with the first set of sub-regions and transform coding in accordance with the second set of sub-regions.
