Claim 17:
18. A non-transitory computer-readable storage medium storing instructions that cause at least one processor to:
obtain a plurality of transform coefficients from video data corresponding to a point cloud, the transform coefficients corresponding to attributes of the point cloud; and
encode the plurality of transform coefficients to generate an embedded bitstream by:
iterating over a first plurality of bit-planes of the plurality of transform coefficients to process all points in the point cloud;
iterating over a second plurality of Levels-Of-Detail (LODs), corresponding to points in the point cloud, in each iteration the first plurality of bit-planes to process all points in the point cloud; and
performing quantization with respect to the plurality of transform coefficients in each iteration the second plurality of LODs that are in each iteration of the first plurality of bit-planes,

wherein the iterating over the first plurality of bit-planes comprises iterating over the first plurality of bit-planes from a Most Significant Bit (MSB) to a Least Significant Bit (LSB), the MSB being of a maximum value of scaled version of a lifting transform coefficient, and the LSB being of a first syntax element that indicates a remainder to be encoded for the lifting coefficient after subtraction of a result of a bitplane coding iteration.
