Abstract
Embodiments of this disclosure relate to binary tree structures, and more specifically to assigning resources to a binary tree structure, such as for content protection. In embodiments, a total number of resources in a first category of resources is identified. The resources may be devices that play encryption protected content such as a CD, a DVD, an HD DVD, a BD, and a Secure Digital card, for example. In embodiments, a minimum number of dummy resources are assigned to a corresponding number of leaf nodes of the binary tree structure before resources in the first category of resources are assigned to leaf nodes in the binary tree structure. Generally, the minimum number of dummy resources is greater than or equal to 1+floor(2^floor(log2(N)−1)), wherein N is greater than or equal to the total number of resources in the first category of resources.
