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 and representing video information, the method comprising:\n extracting, from the data stream, multi-tree subdivision information and inheritance information associated with an inheritance coding block of the array of information samples, the inheritance information indicating as to whether inheritance is used, wherein the inheritance coding block corresponds to a first hierarchy level of a sequence of hierarchy levels in accordance with the multi-tree subdivision information and is composed of a set of coding sub-blocks, each of which corresponds to a second hierarchy level of the sequence of hierarchy levels in accordance with the multi-tree subdivision information; extracting, from the data stream if the inheritance is used with respect to the inheritance coding block, an inheritance subset associated with the inheritance coding block, the inheritance subset including at least one syntax element of a predetermined syntax element type; extracting, from the data stream, respective residual information associated with each of the set of coding sub-blocks; copying the at least one syntax element in the inheritance subset into a set of syntax elements representing coding parameters used in an inter coding process corresponding to each of the set of coding sub-blocks; determining, for each of the set of coding sub-blocks, a coding parameter used in the inter coding process associated with the corresponding coding sub-block based on the at least one syntax element; predicting a respective prediction signal for each of the set of coding sub-blocks based on information associated with a previously reconstructed coding sub-block in accordance with the inter coding process; and reconstructing each of the set of coding sub-blocks based on the respective coding parameter, the respective prediction signal and the respective residual information.
