Assignee: PANASONIC INTELLECTUAL PROPERTY CORPORATION OF AMERICA
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 0:
1. A three-dimensional data encoding method, comprising:
calculating coefficient values from pieces of attribute information of three-dimensional points included in point cloud data;
quantizing the coefficient values individually to generate quantized values; and
generating a bitstream including the quantized values, wherein
each of the coefficient values belongs to any one of layers,
in the quantizing, each of the coefficient values is quantized using a quantization parameter for a corresponding layer to which the coefficient value belongs among the layers,
the three-dimensional data encoding method further comprises calculating the quantization parameter for each of the layers, and
the bitstream includes pieces of first information, the pieces of first information being for the calculating of the quantization parameter for each of the layers.
