Abstract:
A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.

Claim (Index 10):
A method for reconstructing an array of information samples encoded in a data stream, the array of information samples including spatially sampled information samples with regions of different sizes, comprising:\n extracting, from the data stream, multi-tree subdivision information and inheritance information associated with an inheritance region including a set of leaf regions, wherein each of the leaf regions has associated therewith a hierarchy level out of a sequence of hierarchy levels of the multi-tree subdivision and is to be reconstructed based on one or more coding parameters, wherein the inheritance information indicates, with respect to the inheritance region, whether inheritance is to be used for sharing at least one coding parameter among the set of leaf regions; extracting, from the data stream, if the inheritance information indicates the use of the inheritance, at least one syntax element associated with the inheritance region, the at least one syntax element representing a set of coding parameter to be shared among the set of leaf regions; and generating, for each of the set of leaf regions, a respective prediction signal based on the shared at least one syntax element inherited from the inheritance region; and reconstructing each of the subset of leaf regions based on the respective prediction signal.
