Claim Text:
1. A computer-implemented method for video coding, comprising: projecting a reference quadtree pattern associated with a portion of a reference coding unit from a scalable video coding-type reference layer to a target coding unit in a scalable video coding-type target layer based at least in part on the resolution of the target coding unit; determining a target quadtree pattern associated with the target coding unit by performing an inter-layer quadtree pattern prediction between the reference layer and the target layer based at least in part on the projected reference quadtree pattern, wherein the inter-layer quadtree pattern prediction further comprises performing quadtree leaf node adjustment on the projected reference quadtree pattern to form a leaf node adjusted projected reference quadtree pattern, wherein the leaf node adjustment comprises adjusting a splitting pattern for individual leaf nodes associated with the projected reference quadtree pattern on a leaf node-by-leaf node basis based at least in part on individual leaf node split flags associated with individual leaf nodes; and coding the target coding unit based at least in part on the determined target quadtree pattern.
