Inheritance in sample array multitree subdivision

An encoder for encoding an array of spatially sampled video information encoded into a data stream, the encoder comprising:

• a data stream inserter configured to:
• insert, into the data stream, multi-tree structure information associated with the array and an inheritance syntax element, wherein
• the multi-tree structure information specifies a primary subdivision associated with prediction coding of a video array and a subordinate subdivision associated with transform coding of the video array, and
• the inheritance syntax element indicates whether inheritance is used, and if inheritance is used, an inheritance region of the prediction coding which includes a set of leaf regions of the transform coding obtained by sub-dividing the inheritance region via the sub-ordinate sub-division,
• insert, into the data stream, a first intra-prediction mode syntax element and a second intra-prediction mode syntax element, wherein a type of the second intra-prediction mode syntax element depends on the first intra-prediction mode syntax element and the second intra-prediction mode syntax element represents an intra-prediction coding parameter used in an intra mode of the prediction coding associated with the inheritance region, wherein the intra-prediction coding parameter associated with the inheritance region is to be copied into a subset of coding parameters for each of the set of leaf regions of the transform coding, and
• insert, into the data stream, a respective residual signal for each of the set of leaf regions of the transform coding,
• wherein a respective intra prediction signal for each of the set of leaf regions is calculated according to the intra mode of the prediction coding using the intra-prediction coding parameter copied from the inheritance region and a reconstructed reference signal of already reconstructed neighboring leaf regions of the multi-tree structure, and
• each of the set of leaf regions within the inheritance region is reconstructed by combining the respective intra prediction signal and the respective residual signal.

A machine readable non-transitory medium for storing data associated with a multi-view signal, comprising:

• a data stream stored in the non-transitory machine readable medium, the data stream comprising an array of spatially sampled video information, multi-tree structure information associated with the array and an inheritance syntax element, wherein
• the multi-tree structure information specifies a primary subdivision associated with prediction coding of a video array and a subordinate subdivision associated with transform coding of the video array, and
• the inheritance syntax element indicates whether inheritance is used, and if inheritance is used, an inheritance region of the prediction coding which includes a set of leaf regions of the transform coding obtained by sub-dividing the inheritance region via the sub-ordinate sub-division,
• the data stream further comprising a first intra-prediction mode syntax element and a second intra-prediction mode syntax element, wherein a type of the second intra-prediction mode syntax element depends on the first intra-prediction mode syntax element and the second intra-prediction mode syntax element represents an intra-prediction coding parameter used in an intra mode of the prediction coding associated with the inheritance region, wherein the intra-prediction coding parameter associated with the inheritance region is to be copied into a subset of coding parameters for each of the set of leaf regions of the transform coding, and
• a respective residual signal for each of the set of leaf regions of the transform coding,
• wherein a respective intra prediction signal for each of the set of leaf regions is calculated according to the intra mode of the prediction coding using the intra-prediction coding parameter copied from the inheritance region and a reconstructed reference signal of already reconstructed neighboring leaf regions of the multi-tree structure, and
• each of the set of leaf regions within the inheritance region is reconstructed by combining the respective intra prediction signal and the respective residual signal.
