Claim 0:
1. A three-dimensional data encoding method using a first encoding scheme and a second encoding scheme different from the first encoding scheme, the method comprising:
performing transformation, the transformation being one of (i) transforming a first quantization parameter to a first scale value and (ii) transforming the first scale value to the first quantization parameter, based on a first table indicating a correspondence between a plurality of values of the first quantization parameter and a plurality of values of the first scale value, the first table being shared between the first encoding scheme and the second encoding scheme;
performing encoding including a first quantization process to generate encoded attribute information, the first quantization process being a process of dividing, by the first scale value, each of first coefficient values based on items of attribute information of three-dimensional points included in point cloud data; and
generating a bitstream including the encoded attribute information and the first quantization parameter.
