Claim 0:
1. A method of encoding video data corresponding to a point cloud by at least one processor, the method comprising:
obtaining a plurality of transform coefficients corresponding to attributes of the point cloud; and
encoding the plurality of transform coefficients to generate an embedded bitstream, the encoding comprising:
iterating over a first plurality of bit-planes of the plurality of transform coefficients to process all points in the point cloud, wherein each of the first plurality of bit-planes comprises a plurality of bits;
iterating over a second plurality of Levels-Of-Detail (LODs), corresponding to points in the point cloud, within each iteration of 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 within the 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.
