Abstract
A method comprising receiving a syntax element to be encoded as a code word of a set of code words, determining a mapping between the syntax element and the code word on the basis of a hierarchy level in a tree structure, using the mapping to obtain the code word, and updating the mapping is disclosed.
Claims53
A method comprising:
- receiving a syntax element to be encoded as a code word, wherein the syntax element relates to at least one of a coded block pattern, a transform split pattern, or motion partition information;
- determining, by a computing device, a mapping between the syntax element and the code word on the basis of a hierarchy level in a tree structure, wherein the tree structure relates to at least one of a transform block size, a prediction block size, or a block size, and wherein the hierarchy level represents division of a block into smaller blocks;
- using the mapping to obtain the code word;
- and
- updating the mapping.
