1. A method of decoding video data, the method comprising:
determining a ratio between a value of a dimension of a current block of video data and a value of a corresponding dimension of a neighboring block of the current block, the neighboring block being positioned adjacent to the current block;
determining a respective entropy decoding context for one or more of a a split direction syntax element, or a split mode syntax element for the current block of video data based on the ratio;
decoding one or more of the the split direction syntax element, or the split mode syntax element for the current block of video data using the determined respective entropy decoding contexts; and
decoding the current block of video data in accordance with one or more oft the split direction syntax element, or the split mode syntax element for the current block of video data, wherein the split direction syntax element or the split mode syntax element define a portion of a multi-type tree-based partitioning scheme and wherein the multi-type tree-based partitioning scheme includes a binary tree structure and a center-side triple tree structure, and the portion of the multi-type tree-based partitioning scheme comprises partitioning according to one of the binary tree structure or the center-side triple tree structure.
