Inheritance in sample array multitree subdivision

A method for reconstructing an array of information samples encoded in a data stream and representing video information, the method comprising:

• extracting, from the data stream, 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 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, the first hierarchy level being indicated with a lower value than that of the second hierarchy level;
• 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 inheritance subset including the at least one syntax element 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;
• and
• predicting a respective prediction signal for each of the set of coding sub-blocks based on the coding parameter determined for the coding sub-block,
• wherein each of the set of coding sub-blocks is reconstructed based on the respective prediction signal and the respective residual information.

A method for encoding an array of information samples representing video information signal into a data stream, the method comprising:

• inserting, into the data stream, 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 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, the first hierarchy level being indicated with a lower value than that of the second hierarchy level;
• inserting, into the data stream if inheritance is indicated to be used with respect to the inheritance coding block, an inheritance subset including at least one syntax element of a predetermined syntax element type associated with the inheritance coding block, wherein, during decoding, at least one syntax element in the inheritance subset is to be copied 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 in order to reconstruct the coding sub-block;
• and
• inserting, into the data stream, respective residual information for each of the set sub-blocks so that each of the set of coding sub-blocks in the inheritance coding block is to be reconstructed based on a respective prediction signal, which is generated based on one or more of the coding parameters used in the inter coding process, and the respective residual information specific to the coding sub-block.

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 information samples representing video 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 and is composed of a set of coding sub-blocks, each of which corresponds to a second hierarchy level, the first hierarchy level being indicated with a lower value than that of the second hierarchy level,

• the data stream further comprising respective residual information associated with each of the set of coding sub-blocks and, if inheritance is indicated to be used with respect to the inheritance coding block, an inheritance subset including at least one syntax element of a predetermined syntax element type associated with the inheritance coding block, so that the at least one syntax element associated with the inheritance coding block is to be copied as a corresponding syntax element representing a coding parameter used in an inter coding process associated with the corresponding coding sub-block, and each of the set of coding sub-blocks is to be reconstructed based on a respective prediction signal, which is generated based on the coding parameter used in the inter coding process, and the respective residual information specific to the coding sub-block.
