Claim 6:
7. The method of claim 1, wherein constructing a 3D-Unitree comprises:
based on child nodes of the parent node included in a depth other than a last depth of the 3D-Unitree having different values, the value of the parent node of the 3D-Unitree is 1,
based on the child nodes of the parent node having identical values, the value of the parent node of the 3D-Unitree is 0,
based on codebook indices or absolute values of coefficients of a respective one of the plurality of CU3Ds having different values, a value of a node included in the last depth of the 3D-Unitree is 1, and
based on the codebook indices or the absolute values of the coefficients of the respective one of the plurality of CU3Ds having identical values, the value of the node included in the last depth of the 3D-Unitree is 0.
